Answer 10

Prospective Cohort Studys

Answer 11

HOMA-IR stands for HomeOstatic Model Assessment - Insulin Resistance It is a method for estimating beta-cell function and insulin sensitivity from fasting plasma insulin and glucose concentrations The relationship between glucose and insulin in the basal state reflects the balance between hepatic glucose output and insulin secretion, which is maintained by a feedback loop between the liver and β-cells The predictions used in the model arise from experimental data in humans and animals Decreases in β-cell function were modeled by changing the β-cell response to plasma glucose concentrations. Insulin sensitivity was modeled by proportionately decreasing the effect of plasma insulin concentrations at both the liver and the periphery No distinction is made between hepatic insulin sensitivity and peripheral insulin sensitivity. It is used appropriately for cohort and epidemiological studies.

Answer 12

Saturated fat should be less than 10% of total calories e.g. at 9 kcals per gram. For a reminder Protein 4 Kcal per gram CHO 4 Kcal per gram Fats 9 Kcal per gram ETOH 7 Kcal per gram There for for a 2500 kcal diet 10% = 250 kcals so less than 28 grams The lower the better pretty much.

Answer 13

This was a study called Effects of time-restricted eating on weight loss and other metabolic parameters in women and men with overweight and obesity. Q: what is the effect of time-restricted eating on weight loss and metabolic health in patients with overweight and obesity. It was a prospected randomized clinical trial including 116 adults for 12 weeks. Primary outcome was weight loss. Secondary outcomes were weight, fat mass, lean mass, fasting insulin, fasting glucose, HbA1c, estimated energy intake, total energy expenditure and resting energy expenditure. There was no significant difference for the primary or secondary outcomes. (specifically:, there were no significant differences in fat mass, fasting insulin, glucose, HbA1C, or blood lipids between the TRE and CMT groups.) Importantly though: The IF group loss significantly MORE lean body mass than the non-if group. In particular appendicular lean mass (aka arm and leg muscle). In particular they showed 65% of weight loss was lean mass in the TRE group when weight loss typically causes 20-30% of weight loss to be lean mass. However the eating window here was 12- 8 pm. Not early which Sutton et al., 2018 may have demonstrated it needs to be before 3 pm with a 6 hour eating window.

Answer 14

Sutton et al., 2018 published in Cell Metabolism a study "Early time-restricted feeding improves insulin sensitivity, blood pressure and oxidative stress even without weight loss in men with prediabetes.

It produces N-nitroso compounds (NOC), hererocyclic amines (HCA) and polycyclic aromatic hydrocarbons (PAH) that are potentially carcinogenic. N.B. even if something says nitrate free - and they preserve with celery juice - this still has a high nitrate content...

Answer 16

This study, titled "Saturated fat as compared with unsaturated fats and sources of carbohydrates in relation to risk of coronary heart disease: a prospective cohort study. Again another study that used the Nurses Health Study and Health Professionals Follow-up study Review picture in file associated with this card Isocaloric substitution of CHO from refined starches/added sugars in PUFA significantly reduces CVD risk up to 30% Substituting refined starches/added sugars doesn't benefit. Substituting trans fat is worse. Siri-Tarino SW, et al. 2015 in Annual Review of Nutrition supports these in their paper.

Answer 20

A double sided reflection involves both a pro-change statement and a resistant statement that the patient has made. .e.g. You say you know you need to exercise more regularly but that you find you have no time to do so.

Answer 21

A BMI of 23.0 to 27.5 kg/m2 is considered overweight for Asians. A BMI of ≥ 27.5 is considered obese for South Asian or Chinese Decent. - According to WHO advice on BMI. For people of South Asian or Chinese descent, the range is likely to be between 18.5 and 22.9 kg/m2 for health range. It's prudent to use these same thresholds amongst black people for prevention of diabetes. Alberti et al., 2007 International diabetes federation guidance: suggests that men with a waist circumference greater than 90 cm (35 inches) and women with a waist greater than 80 cm (31.5 inches) should be considered overweight. from NICE PH46 The evidence gathered does confirm that people from these groups are at an equivalent risk of diabetes, other health conditions or mortality at a lower BMI than the white European population. However, the Committee did not consider the evidence sufficient to make recommendations on the use of new BMI and waist circumference thresholds to classify whether members of these groups are overweight or obese.

Answer 22

1. Health Belief Model 2. Theory of Planned Behaviour 3. Social Learning, cognitive theory 4. Stages of change, transtheoretical model

Answer 23

First developed in the 1950s by Public health, looking at why people didn't adopt screen tests etc. Self - efficacy - the confidence in ability to act and succeed in completing the change Before seeking preventative measures one needs to 1. Believe there is a threat to health (perceived susceptibility, perceived severity 2. Believe that there is a preventative measure that is accessible and low risk (perceived benefit outweighs perceived barriers) 3. That the preventative measure will allow him to avoid the health trheat 4. There should normally be a cue to action, driving self-efficacy. Worked example could be. Perceived threat is heart disease causing morbidity or death. Perceived susceptibility might be low as assumes they are fit enough (walking everyday/fitter than their peers, not had any issues so far. Or perceived severity (even if I have a heart attack it won't be that bad because other people have them). Preventative measure could be adopting a Mediterranean/whole food plant based diet. Perceived barrier could be, doesn't know how to cook/prepare the foods/what foods it involves. (food islands etc). Could be a financial cost that doesn't out weigh perceived benefit of reducing risk of heart attack. Cue to action could be having a heart attack. (or medical reminders). Self-efficacy is the confidence in adopting in this example the change in diet. Can be considered under 3 topic headings. Individual perceptions Modifying factors Likelihood of Action It doesn't take into account that some behaviours are habitual (like smoking) Doesn't account for emotions or social aspects of disease. E.g. family could be influencing decisions.

Answer 24

Personal intention to engage in health behaviour is influenced by: 1. Beliefs (social normals/subjective norms, perceived power) 2. Attitude (evaluation about the risks, benefits, and capability of achieving (perceived behavioural control) the desired health outcome. So you have 1. Attitude towards the behaviour 2. Subjective norm 3. Perceived behavioural control Linking into intention and then behaviour B. Behavioural intent / internal motivation From Jeni Schul Attitude to weight lifting (she thought she could be silly, Subjective/social normals - most females were not weight liftings. Perceived control - didn't have access to tools needed. These all lowered intention and behaviour. Friendship group changed. More girls who lifted, attitude towards it changed - important for bone health etc. Access to better gyms, intention changed. and lifting behaviour achieved. Published by Ajzens theory of planned behaviour 1988

Answer 25

Developed in 1960 - combined theory in 1980s. ``` Personal factors (influence on thoughts and actions) - ta Environment (Culture, communication: talking with friends, policies) Human Behaviour (response to stimuli to achieve goals) ``` Reciprocal determinism, the person, the behaviour and the environment all influence each other in a dynamic and reciprocal fashion. Behavioural capability, self-efficacy. e.g. Observing an act of kindness, we are more likely to do an act of kindness.

Answer 26

Originally develop for smoking cessation. Describes something as a process rather than something that occurs quickly. Different interventions can be used at different stages, stages can be skipped, moved through quickly or maintained. 1. Precontemplation No awareness of problem behaviour, no plan for change 2. Contemplation Considering change in the next six months 3. Planning Aware of need to make change, prepare for change in next month May be making changes but no achieved goal. 4. Action Making change and goal behaviour achieved Behavioural change for less than 6 months. 5. Maintenance Made behavioural change for at least 6 months or more. (6). Relapse Goal behaviour change no longer happening. Patients once they've been in the maintenance phase aren't at risk of relapse as they were before.

Answer 27

1. Express empathy Opened ended questions, reflective listening, normalising feeling and concerns, support autonomy right to choose or reject change. 2. Developing discrepancy High discrepancy between patients values, goals, priorities and present behaviour Reinforce and support change talk and commitment language Build and deepen commit to change. 3. Roll with resistance Back off and use reflection when patient expresses resistance empathy Ask permission to provide information (can I tell you about the benefits of stopping smoking? Can I tell you about the benefits of eating more fruits and vegetables?) 4. Support self-efficacy Motivational interviewing is most helpful in the pre-contemplation and contemplation stages.

Answer 28

1. Autonomous or Internal motivation 2. External motivation produced by environment. Self-motivation and self-confidence are key for self-efficacy Self-confidence can be increased by eliciting positive emotions, leveraging strengths, developing strong support system and appropriate stage matched education. Self-efficacy is an individuals belief in his or her capacity to execute behaviour necessary to produce specific performance attainments. Self-confidence is understanding that you trust your own judgement and abilities Self-motivation is the drive, internal or external to continue, produce, develop or attempt.

Answer 29

``` All or nothing Catastrophising discounting the positive overgeneralising mind reading fortune telling (this will never work) Should and must statement. ``` You need to reframe non-productive thinking, examine the evidence for and against nonproductive thoughts. You can use self-talk - might feel forced at first but it can be helpful (I know this is difficult but I can do this).

Answer 30

relates to A: what ACTION or event occurred B: What BELIEFs do you have about what occurred C: What are the CONSEQUENCES of those beliefs, how does that make you feel? D: How can you DISPUTE those belief that seem to be distorted or unhealthy? Example: ACTION; eats package of sweets BELIEF: still had work to do and thought it would give me a boost CONSEQUENCES: I felt guilty for eating so much, I wished I'd had, had a good snack instead DISPUTE: In reality could have had a glass of water, I could have had a walk, I could have picked a high fiber food instead.

Answer 31

Patient centeredness, encourage internal motivation for change. It is not advice - not giving information. Its aiming to put patient at centre. Assess - health behaviour risk Advice - to change behaviour with clear, specific personalised advice. Agree - on the focus of the counselling and treatment based on patients interested and willingness. Assist - the patient in setting and achieving goals to change practices - here we can address motivational barriers, determine the need for additional information or help and refer if needed Arrange follow up and support. ** The 5A’s begin with assessing patient beliefs, behaviors, and knowledge, then advising by providing information about the health benefits of change, and then agreeing on a collaborative goal. Next, the provider assists the patient in identifying barriers, strategies and problem-solving techniques before finally arranging to follow up on plans.

Answer 32

Ask - identify tobacco use Advice - clear strong personalised for quitting Assess - is the tobacco user ready and willing to make a quit attempt Assist - provide counselling and or pharmacotherapy for those who are ready Arrange - schedule follow up and accountability, preferentially one week prior to quit date and three days following quit date. N.B. NICE advises Initially, follow the person up after: 2 weeks of nicotine replacement therapy (NRT). 3-4 weeks of treatment with varenicline or bupropion. Measure the carbon monoxide (CO) level 4 weeks after quitting. A CO level of 10 ppm or less suggests the person is a non-smoker. Thereafter, use professional judgement about the number, timing and frequency of appointments offered.

Answer 33

10 hour training achieves similar empathy results as those providers who have had longer training on empathy.

Answer 34

1. CBT techniques - especially when patients are dealing with feeling of outside pressures, failures ore being out of control 2. social support strategies 3. Community and employee programs 4. Support with digital technology

Answer 35

A short term period when an action plan is not followed. A relapse is a sustained period when an action plan is not adhered to. It requires following the same steps as starting a new action plan. You must address thoughts and emotions arising from a potential feeling of failure. Here the unhealthy behaviour may have become a habit again. Relapse prevention involves: a) when might a lapse occur b) under what circumstances c) with whom d) how to notice a lapse before it becomes a relapse e) who to turn to during a lapse or a relapse

Answer 36

Lifestyle prescriptions are actions needed to treat or prevent a condition based on the scientific evidence and the patient's medical condition e.g. 150 minutes of moderate physical activity per week. Action plans are the lifestyle prescription ADJUSTED for the patient's ability readiness and confidence. Action plan for achieving prescription: start with walking 5 minutes each day for 5 days a week. Then increase as tolerated up to the 150 minutes.

Answer 37

Increased appetite lasts the longest at more than 10 weeks and affects 70% Depression lasts less than 4 weeks and affects 60% This is similar for restlessness & poor concentration Nicotine craving lasts more than 2 weeks and affects 70% Disturbed sleep is less than a week and affects 25% Light-headedness is less than 48 hours and afffects 10% Irritability/aggression affects around 50% of people and lasts less than 4 weeks. on average 5 - 9 kg of weight gain occurs in people not adopting other healthy diet change when stopping smoking.

Answer 38

Answer 39

Three causes account for 70% of these deaths: lung cancer, chronic obstructive pulmonary disease (COPD) and vascular disease. More than a quarter of all cancer deaths can be attributed to smoking (including lung, oral, throat, bladder, kidney, pancreatic, stomach, liver and cervical cancers)

Answer 40

Very brief advice (VBA) It is typically less than 30 seconds. ASK about current and past smoking behaviour [relate this to 5 As] - Two most important indicators are How many cigarettes they smoke per day (0 points for <=10, 1 for 11- 20, 2 for 21-30, 3 for >=31 How soon after waking they smoke their first cigarette 3 points for within 5 minutes, 2 for 6 - 30 mins, 1 for 31 - 60 and 0 for after 60 minutes. Ask about previous quit attempts if successful and if they tried treatment, whether they had support and the experience of withdrawal symptoms and cravings. ADVISE with verbal and written information on the risk of smoking and benefits of stopping. Include treatment options, behavioural support, medication and e-cigarettes. The best way to quit is behavioural support and medication, set and quit date and commit to it. The hardest day are first 48 hours. Identify lapse and relapse triggers Stress, seeing other smoking, drinking (intoxication). Discuss medications. distraction techniques. There is a not-a-puff rule: the first lapse, such as a single puff from a cigarette almost always leads to ther person going back to regular smoking. 3/4 of people who relapse do so because of being with others who are smoking. Discuss barriers (weight gain). ASSESS is the person ready to quit? If they are continue if not think about harm reduction approach* ASSIST provide the prescription for which suits them best, refer to local stop smoking service ARRANGE - follow up Record the smoking status at every opportunity.

Answer 49

The best intervention is motivational interviewing. guiding style to engage clients, clarify their strengths and aspirations, evoke their own motivations for change and promote autonomy in decision making R - resist the urge to change the individual’s course of action through didactic means U - understand it’s the individual’s reasons for change, not those of the practitioner, that will elicit a change in behaviour L - listening is important; the solutions lie within the individual, not the practitioner E - empower the individual to understand that they have the ability to change their behaviour. (Rollnick et al 2008)

Answer 50

Cognitive Behavioural Therapy is the best intervention when someone is in the preparation, action & maintenance steps. The basic principles: Recognising and reframing non-productive thinking Being more aware of underlying beliefs and emotions (getting patients to connect their emotions with their actions). working through the ABCD of behavioural change A what action or even occurs B What beliefs do you have about what occurs C what were the consequences, how does that make you feel D How can you dispute those beliefs. In ALL stages use positive psychology (emphasing the postives, silver lining etc). .

Depression is 40% more likely to develop in adults who frequently eat fast food compared to those who avoid it. There MIGHT be some benefit to omega 3 intake in depression or bipolar.

Answer 53

Eudaimonia the perspective that happiness comes from inherent meaning and purpose, and human nature works to discover that meaning, finding what nourishes and what dampens it in order to live life in a full and deeply satisfying manner. Eudaimonia is associated with: less activation of the amygdala; more engagement of higher cortical function with negative stimuli; and sustained activation of the reward circuit with positive stimuli. Eudaimonia appears to aid adaptive and protective functions, and it’s associated with greater insular cortex volume. Eudaimonia is associated with gene regulation: pro-inflammatory genes are down-regulated while antibody synthesis genes are up-regulated. Hedonia is associated with the opposite pattern. Hedonia is the perspective that happiness is characterized by the presence of positive emotions and expressions and the absence of negative emotions and expressions, with an overall high amount of life satisfaction. The thought process behind hedonia is that humans are born empty, and they acquire meaning through social and cultural interaction.

Answer 60

meta-epidemiological study included 305 randomized controlled trials (RCTs) and found that exercise decreased mortality more than medications in post-stroke studies. Exercise also had an equivalent effect on mortality to medications for the secondary prevention of coronary artery disease (CAD) and pre-diabetes, but it was inferior to medications with regard to heart failure patients. [Naci et al. Comparative effectiveness of exercise and drug interventions on mortality outcomes: metaepidemiological study. BMJ. 2013]

Answer 61

People who want to lose a substantial amount of weight (more than 5% of body weight) and people who are trying to keep a significant amount of weight off once it has been lost need a high amount of physical activity unless they also reduce their caloric intake. Many people need to do more than 300 minutes of moderate-intensity activity a week to meet weight–control goals. Seventy-five minutes is likely insufficient to meet health recommendations or weight loss goals. Two and a half hours would be appropriate for general health benefits. Seven hours may offer additional health benefits and further assist with weight loss efforts

Answer 62

Research has shown that goal weight loss for health benefits is five to 10%, however weight loss of 15 to 20% may be necessary for continued disease improvement in individuals who have a BMI > 35 and comorbidities.

Answer 63

Answer 68

Sodium restriction typically reduces blood pressure by 2.5 to 7 mmHg. According the American Heart Association, the ideal limit of sodium should be less than 1.5 grams daily, with the upper limit being 2,300 mg daily. The largest sources of sodium in the US are processed foods and canned foods.

Answer 69

Facts learned from 2013 Baylor University Conference: If the serum total cholesterol is 90 to 140 mg/dl (2.327 - 3.620mmol/L), there is no evidence that cigarette smoking, systemic hypertension, diabetes, inactivity or obesity produces atherosclerotic plaques. Hypercholesterolemia is the only direct atherosclerotic risk factor, the others are all indirect. Optimal LDL is 50 to 70 mg/dl (1.293 - 1.810mmol/L). Plaque progression ceases with total cholesterol < 150 mg/dl (3.879mmol/L).

Answer 70

Participants were not placed on a strict diet. Rather, they were encouraged to gradually achieve the fat and calorie levels through: better choices of meals and snack items; healthier food preparation techniques; and careful selection of restaurants, including fast food and the items offered. The initial focus of the dietary intervention was on reducing total fat rather than calories. This allowed participants to accomplish a reduction in caloric intake while at the same time emphasizing overall healthy eating. It also streamlined the self-monitoring requirements, which was important given the diversity of educational and literacy levels among participants. After several weeks, the concept of calorie balance and the need to restrict calories as well as fat was introduced. The calorie goals were calculated by estimating the daily calories needed to maintain the participant’s starting weight and subtracting 500 to 1,000 calories per day (depending on initial body weight) to achieve a one to two pound per week of weight loss. The fat goals, given in grams of fat per day, were based on 25% of calories from fat. Four standard calorie levels were used: 1,200 kcal per day (33 grams fat) for participants with an initial weight of 120 to 170 lbs; 1,500 kcal per day (42 grams fat) for participants with a weight of 175 to 215 lbs; 1,800 kcal per day (50 grams fat) for participants with a weight of 220 to 245 lbs; and 2,000 kcal per day (55 grams fat) for participants weighing >250 lbs. The fat and calorie goals were used as a means to achieve the weight loss goal rather than as a goal in and of itself. Therefore, if a participant reported

This is the lifestyle heart trial. It randomised 48 adults with coronary artery disease into TWO groups. Randomized controlled trial conducted from 1986 to 1992 using a randomized invitational design. Objectives: To determine the feasibility of patients to sustain intensive lifestyle changes for a total of 5 years and the effects of these lifestyle changes (without lipid-lowering drugs) on coronary heart disease. Main outcome measures: Adherence to intensive lifestyle changes, changes in coronary artery percent diameter stenosis, and cardiac events. Forty-eight patients with moderate to severe coronary heart disease were randomized to an intensive lifestyle change group or to a usual-care control group, and 35 completed the 5-year follow-up quantitative coronary arteriography. 20 received usual care - including advice about health eating & exercise. 28 received lifestyle intervention. Which was a low fat (10%) vegetarian diet (The diet consists of unlimited consumption of fruit, vegetables, grains, beans, and legumes and restricts all meats (including fish), oils and fats, nuts, avocados, dairy products, and simple carbohydrates) aerobic exercise, smoking cessation, stress management and group psychosocial support. 4 No lipid lowering medications CAD stenosis were assessed with blinded quantitative at baseline N.B. There was self selection bias as 50% refusal rate amongst people. So not truely randomised. Outcomes: Experimental group at 5 years 37.3 % stenosis vs 59.7% for the control not taking a statin. There for a relative reduction of 7.9% vs 27.7 INCREASE in control group. The control group had 45 cardiac events (angioplastic, bypass, hosptalisation, MI or death) vs 25 in the experimental group. Risk ratio of 2.47 (more than twice the rate of cardiac events) There was a dose response to the intervention with 82% showing a regression in the experimental group.

Changes in prostate gene expression in men undergoing an intensive nutrition and lifestyle intervention Pilot study conducted to determine changes in prostate gene expression in a population of men with low-risk prostate cancer. The study participants all declined immediate surgery, hormonal therapy, or radiation and participated in an intensive nutrition and lifestyle intervention while undergoing careful surveillance for tumor progression. This study is known as the Gene Expression Modulation by Intervention with Nutrition and Lifestyle (GEMINAL) study. 30 men completed the protocol. 3 month lifestyle modification used 3 day residential outpatient phase where they was weekly telephone contact with a study nurse. Everyone showed improves in weight, abdominal obesity, BP, lipid profiles. They also had paired prostate biopsies taken at start and end. These showed modulated gene expression: (reduction in gene transcription). Only 30% of these biopsies contained tumour - major limitation.

Study: Reversal of type 2 diabetes: normalisation of beta cell function in association with decreased pancreas and liver triacylglycerol Eleven people with type 2 diabetes (49.5 ± 2.5 years, BMI 33.6 ± 1.2 kg/m(2), nine male and two female) were studied before and after 1, 4 and 8 weeks of a 2.5 MJ (600 kcal)/day diet 8 non-diabetics as matched controls Fasting plasma glucose normalized in the diabetic group (from 9.2 ± 0.4 mmol/L to 5.9 ± 0.4 mmol/l, or 166 ± 7.22 mg/dL to 106 ± 7.22 mg/dL; p=0.003). Insulin suppression of hepatic glucose output improved from 43 ± 4% to 74 ± 5% (p=0.003) versus controls 68 ± 5%. Hepatic triacylglycerol content fell from 12.8 ± 2.4% in the diabetic group to 2.9 ± 0.2% by week eight (p=0.003). The first-phase insulin response increased during the study period (0.19 ± 0.02 to 0.46 ± 0.07 nmol /min /m2; p<0.001) and approached control values (0.62 ± 0.15 nmol /min /m2; p=0.42). Maximal insulin response became supranormal at eight weeks (1.37 ± 0.27 versus controls 1.15 ± 0.18 nmol /min /m2). Pancreatic triacylglycerol decreased from 8.0 ± 1.6% to 6.2 ± 1.1% (p=0.03). The study showed that reducing dietary energy intake can reverse the abnormalities underlying type 2 diabetes.

Answer 81

Association of an intensive lifestyle intervention with remission of type 2 diabetes This is the LookAHEAD trial. Many people thought that bariatric surgery was better due to the modest outcomes. To examine the association of a long-term intensive weight-loss intervention with the frequency of remission from type 2 diabetes to prediabetes or normoglycemia. observational analysis of a 4-year randomized controlled trial (baseline visit, August 2001-April 2004; last follow-up, April 2008) comparing an intensive lifestyle intervention (ILI) with a diabetes support and education control condition (DSE) among 4503 US adults with body mass index of 25 or higher and type 2 diabetes. Intervention: Intensive:weekly group and individual counseling in the first 6 months followed by 3 sessions per month for the second 6 months and twice-monthly contact and regular refresher group series and campaigns in years 2 to 4 (n=2241) They also followed a 1,200 to 1800 kcal diet. with reductions in total and sat fat Also aimed for 175 minutes a week of physical activity. The DSE, which was an offer of 3 group sessions per year on diet, physical activity, and social support (n=2262). Outcome measures: Partial or complete remission of diabetes, defined as transition from meeting diabetes criteria to a prediabetes or nondiabetic level of glycemia without hypoglycaemics. ILI weight loss at 1 year <7.9% 4 years 3.9% versus diabetes education ILI had greater fitness - difference 15.4% at 1 year and 6.4% at 4 years ILI was more likely to experience remission 11.5% prevalence first year, 7.3% at year 4 Compared to 2% in the education. in ILI 9.2%, 6.4% and 3.5% had sustained remissions for 2, 3 & 4 years.

Published in JAMA 2018 To determine the effect of a healthy low-fat (HLF) diet vs a healthy low-carbohydrate (HLC) diet on weight change and if genotype pattern or insulin secretion are related to the dietary effects on weight loss. 609 adults aged 18 to 50 years without diabetes with a body mass index between 28 and 40. Randomized to the 12-month HLF or HLC diet. The study also tested whether 3 single-nucleotide polymorphism multilocus genotype responsiveness patterns or insulin secretion (INS-30; blood concentration of insulin 30 minutes after a glucose challenge) were associated with weight loss. Health educators delivered the behavior modification intervention to HLF (n = 305) and HLC (n = 304) participants via 22 diet-specific small group sessions administered over 12 months. The sessions focused on ways to achieve the lowest fat or carbohydrate intake that could be maintained long-term and emphasized diet quality. Primary outcome was 12-month weight change and determination of whether there were significant interactions among diet type and genotype pattern, diet and insulin secretion, and diet and weight loss. participants were not being instructed to follow a specific caloric restriction, the mean reported energy intake reduction relative to baseline was approximately 500 to 600 kcal per day for both groups at each time point after randomization. Weight change at 12 months was −5.3 kg (-11.7 lbs) for the healthy low-fat diet versus −6.0 kg (-13.2 lbs) for the healthy low-carbohydrate diet There was no significant diet-genotype pattern interaction (P = .20) or diet-insulin secretion (INS-30) interaction (P = .47) with 12-month weight loss. Eighteen adverse or serious adverse events were evenly distributed across the two diet groups. Previous research suggests genotype or insulin-glucose dynamics may modify the effects of diets. Neither of the two hypothesized predisposing factors was helpful in identifying which diet was better for whom. They comment: These results are inconsistent with similar analyses of other dietary weight loss intervention cohorts, and it seems implausible there is no interaction between genotype and weight loss with different macronutrient dietary patterns.

This was the DiRECT trial: Primary care-led weight management for remission of type 2 diabetes (DiRECT): an open-label, cluster-randomised trial In the UK, published in the lancet. Aimed to assess whether intensive weight management within routine primary care would achieve remission of type 2 diabetes. Open label, cluster-randomised. at 49 primary care practises in Scotland & Tyneside. T2DM diagnose within 6 years, BMI 27 - 45, not on insulin and 20 - 65 yrs Intervention: (1) withdrawal of antidiabetic and antihypertensive medications, and (2) total diet replacement (825 to 853 kcal per day formula diet for three to five months), and (3) stepped food reintroduction over a period of two to eight weeks, and (4) structured support for long-term weight loss maintenance. or Standard guidelines Outcomes were weight loss of 15kg or more remission of diabetes HbA1c <48 after 2 months off all antidiabetic medications during the 12 month study period. 306 individuals 24% achieved the 15kg loss in the intervention, but non in the control. Diabetes remission 46% in the intervention, 4% in controls. Odds 19.7 Remission was associated with weight loss. Remission not achieved in the 76 who gained weight. The more weight loss the higher the percentage of remission. Mean body weight fell by 10kg in intervention and 1 kg in the control. QOL improved in intervention. Nine serious adverse events by 7 of the intervention group. 2 by the control group. Importantly this DIRECT trial found that unlike the LookAHEAD which had 11.5% and 6% remssion at year 1 and 4. Here they had 46% had remission at 12 months.

Answer 85

he healthcare approach toward lifestyle-related diseases needs to change. Huge health and economic profits could be achieved if everyone would adopt an “optimal” lifestyle. This article presents abundant scientific evidence that lifestyle interventions can lead to major reductions in obesity, type 2 diabetes, and cardiovascular disease. The (economic) benefits of a lifestyle-based therapy for type 2 diabetes have been demonstrated by a 10-year study, yet the introduction of a new healthcare system for preventing and treating lifestyle-related diseases has not materialized for a number of reasons, as discussed in this article. One of the major reasons lifestyle measures aren’t used in clinical practice is that it’s difficult for patients to sustain the changes. In the short term, or in a setting where the lifestyle choices are rigidly imposed, lifestyle change can be achieved, but in the long term the daily life changes fade away due to a lack of support and the many counteracting stimuli from environmental pressures. Another reason lifestyle as medicine has failed to take hold is the lack of economic benefits within the context of our current healthcare system. And a major reason is the failure to take a systems approach instead of making reductionistic changes. Thus, the theory and practice differ, and we face a multifactorial challenge that requires removing economic, social, psychological and biological barriers. A reorientation of health research and care is needed, starting with: re-defining health and its underlying mechanisms; realizing that integrated participatory and personalized health optimization strategies are needed; redesigning the methods to quantify health toward the development of a new generation of health biomarkers, lifestyle interventions, support tools and economic values. All of these changes need to be focused on self- empowerment, as listed below. Refocusing on flexibility as a core characteristic of human physiology, meaning that chronic disease is reversible. Diagnosis has to quantify much more than the medical condition. A 360° diagnosis is needed to determine all the relevant biological, sociological, psychological and contextual conditions of the patient. The trajectory toward disease needs to be identified and quantified in order to empower the individual to achieve a sustainable and perceivable lifestyle change. Interventions will need to span all relevant bio-socio-psycho-economic factors and thus change from reductionist to systemic and from generic to fine tuned toward personal goals. Motivational tools are required in the form of personal coaching as well as Information and Communications Technology (ICT) support. Health literacy needs to be improved as part of personal health empowerment. Personal health data handling needs to completely refocus in order to empower the citizen/patient to valorize their health data for personal health and research. Together, the points above need to lay the foundation of a new approach in lifestyle-related health science and a new health economy. Type 2 diabetes is a “genotype–environment interaction disease”, meaning the diabetic phenotype is expressed as a result of accumulated environmental pressures (including wrong diet, too little physical exercise, disrupted sleep and too much stress) in concert with genes that render individuals susceptible to the disease. Over the past 50 years our environment has changed in ways that have increased the burden of all four components mentioned. Reversal and cure of type 2 diabetes thus needs to focus on: (1) biological reversal (i.e., using lifestyle as medicine), (2) coping with the environmental pressures (i.e., behavioral change), and (3) reduction of the environmental pressures (i.e., socioeconomic changes). In this article, the authors provide evidence for the reversibility of insulin resistance and the remission of type 2 diabetes by diet and lifestyle, asserting that complete cure may be achieved if beta-cell function is still appropriate and complications have not yet occurred. They demonstrate that type 2 diabetes is a “systems disease” with multiple organs and processes involved, and assert that the disease deserves to be treated in a personalized manner, and if necessary in a “personalized lifestyle-personalized medicine combination.” Compliance to lifestyle change has been a major obstacle for implementation in healthcare, but the advancements in behavioral change technologies, eHealth, health literacy, and personal health data valorization may now allow for a switch from a research setting to real-life socioeconomic implementation. There are enough arguments and instruments currently available to (1) implement a lifestyle-based therapy for type 2 diabetes and other food-related lifestyle diseases and (2) extend this to a prevention and optimal health focused healthcare. Also, they argue that in implementing a lifestyle-based healthcare system there will be an enormous economic gain. This economic gain will in turn finance healthcare system changes and economic changes that support lifestyle-based approaches for optimal health and prevention. Since stakeholders, losses, and profits in this new economy will be substantially different from the current situation, the present healthcare industry will transit slowly toward this new system. Therefore, creative ways to implement these changes need to be explored. Ultimately, health data cooperatives may become the basis and drivers for this change, but this will take some time to develop into an economic reality. In the meantime, creative new “ecosystems” need to be explored that combine all the necessary instruments for specific type 2 diabetes populations to be really effective. The goal would be to demonstrate its therapeutic efficacy but also—and possibly more important—to demonstrate that a new health economy that provides the necessary support services can become profitable while significantly reducing net healthcare costs. (Those services would including coaching, ICT, foods, diagnostics and medication, all of which should be personalized and integrated). Such ecosystems should preferably be regional, facilitating the simultaneous change of all relevant components in the “change system” to interact. This will allow community building and involvement of local healthcare centers, the local health and lifestyle-related economy and others. The Chicago-based South Side diabetics project, Improving Diabetes Care and Outcomes on the South Side of Chicago, is a good example. The key point is that many early adopter activities, programs and movements are already active in this area, and they’re covering parts of what’s needed. A challenge will be to connect and integrate these efforts into functional and flexible programs that can deliver “tailored systems solutions” depending on the personal and subgroup needs. The major challenge will be to fund these programs, at least to the point that they become self-sustainable. Here, sustainability does not necessarily imply a profitable service as such, but rather the identification of new natural funders, those being the entities that profit from the new systems. In addition to the actual service providers, these natural funders can include governments, health insurance, employers and investors.
