A very low fat plant based diet was shown to reverse and prevent major cardiac event in 177 adherent patient over 3.7 years, Among 177 adherent patient cardiac event rate was 0.6%. among 21 non adherent patients 13 ( 62%) experienced major cardiac events.
The CHIP complete health improvement program and plant based dietary intervention with cost savings.
The program was found to be effective in treating type 2 DM and to have a positive return on investment with in a few months.
percutaneous angiography compared with exercise training in patient with stable CAD.
- to determine if patients with stable CAD can improve myocardial perfusion and reduce disease progression
- to compare the effects of exercise training to standard PCI with stenting on: clinical symptoms, angina free exercise capacity, myocardial perfusion, cost effectiveness, frequency of combined cardiac events
( death of cardiac cause, CABG, angioplasty, Acute MI, worsening of angina resulting in hospitalisation) - duration 12 months
- 101 male patient <=70 Germany
- Ergo spirometry
- 20 mins of bicycle ergometry
- cost effectiveness was calculated on average expanse US dollars needed to improve the Canadian cardiovascular society class by 1 CCS
*
*
Key results: exercise training associated with
- high event free survival 88% vs 70% for PCI resulting in 26% low risk in exercise group than PCI group.
- increased O2 uptake 16%
- increased exercise tolerance to by 20%
- increased ischaemic threshold by 30%
- significantly increased HDL after 12 months HDL decreased in control. LDL remained unchanged during study period.
- in the PCI group only ischaemic threshold showed a significant increase after 12 months.
- clinical symptoms improved in both groups
- to gain 1ccs class $6956 PCI vs $3429 in training group
- in both groups symptoms significantly improved
- physical work capacity increased 133w to 159w in exercise group but no change in PCI group
- resting heart rate was low in exercise group and the maximal heart rate and Vo2 max higher in exercise group at the end of the study.
- exercise training more cost effective due to lower repeat hospitalisations and revascularisation as exercise capacity improved in exercise group.
VO2 max: 22.6 ml/kg to 26.2in exercise group
22.3 to 22.8 in PCI group.
Comparison of Atkins ( low carb), Ornish (Low Fat), Weight Watchers ( calorie restriction) , and Zone’s diet (macronutrient balance) for weight loss and heart disease.
- RCT one year JAMA 2005 Boston MA USA
- Each diet reduced LDL/HDL ratio by 10% and no significant effect on glucose or BP @ one year.
- the amount of weight loss was associated with self reported dietary adherence levels but not with diet type.
- for each diet weight loss was associated with decreased total cholesterol and HDL ratio, CRP and insulin with no significant difference between diets.
- overall adherence rate was low. <25%
- 160 patients 40 each for each diet.
- discontinuation rate 50% for Ornish, 48% for Atkins both extreme diets, 35% for Zone and WW both Moderate diets: reason not yielding enough weight loss and too hard to follow.
- Adherence and intensity of intervention is more important than the specific diet for weight loss. Intensity is directly related to adherence.
The Geminal Study: Gene expression modulation by intervention with nutrition and lifestyle: Ornish Magbanua USA 2008
Pilot study to determine changes in prostate gene expression in a population of men with low risk prostate cancer undergoing intensive nutrition and life style intervention.
* N; 30
* 3 days intensive residential retreat followed by an outpatient phase of weekly tel contact.
* careful surveillance of tumour progression.
* outcomes significant improvement in weight, abdo obesity, BP, lipid profile,
* biopsy taken before and 3 months post intervention
*pairing in RNA samples
* low fat 10% calories from fat, whole food plant based diet, patients were provided with all their food,

* stress management: 60 mins of daily yoga based stretching, breathing meditation, imagery, or progressive relaxation.
* moderate aerobic exercise 30 mins walking /day 6 days a week.
* a one hour of group support session per week.
* after 3 months they reported: 11.6% of fat cal/day, exercising 3.6 hours/week, and practising stress management 4.5 hours/week.
*limitations: small group, absence of comparison group: this prevents us from definitely saying that gene expression changes are due to the comprehensive lifestyle modification and not due to normal changes in the gene expression.
Large RCT needed.
* Bonferroni correction: to correct large no: of data points.
* only 30% biopsies had tumour tissue. these results are based on normal tissue for male with prostate cancer. This indicate that lifestyle modifications can affect cancer and normal tissue and benefits of lifestyle modifications not only restricted to gene associated with prostate Ca.
although the results are largely based on normal tissue in male with prostate cancer that doesn’t mean that the results indicate that life style modifications doesn’t apply to prostate cancer.

Answer: CG
Reversal of Type 2 Diabetes: Normalisation of Beta Cell Function in Association with Decreased Pancreas and Liver Triacylglycerol
Hollingsworth et al, 2011
P347 of manual
Objectives
1) Can both beta cell failure and insulin resistance be reversed by dietary restriction of energy intake?
2) Does acute negative energy balance alone reverse Type 2 Diabetes by normalising both beta cell function and insulin sensitivity?
Study design
Case-control study (intervention study)
Intervention group
N=11
Type 2 Diabetes
Age 35-65 yrs
HBA1c 6.5-9.0% (48-75mmol/L)
Diabetes duration < 4yrs
BMI 25-45kg/m2
Asked to continue their habitual pattern of eating till start of the study.
For the study, restricted 600 calorie/day diet and statin therapy continued
Control group
N=9
Matched for weight, age, sex
Assessments of beta cell function, insulin sensitivity, liver and pancreatic fat content and total body fat at:
Baseline (day -1), after 1, 4 and 8 wks of low-energy diet
Results
After one week of restricted energy intake
- Fasting plasma glucose normalised in diabetic group
- Insulin suppression of hepatic glucose output improved vs control group
- Hepatic triacylgycerol content fell in diabetic group by week 8
- First-phase insulin response increased during study period and approached control values
- Maximal insulin response became supranormal vs controls
- Pancreatic triacylglycerol decreased
Strengths
- Demonstrated for the first time that normal blood glucose levels without medication achievable after 1 week with a very low energy diet and accompanied by reversal of hepatic and pancreatic triacylglycerol in the subsequent 3-4 weeks.
Limitations
- Small sample size (necessary to allow for metabolic investigation and examination by magnetic resonance techniques)
- Pancreatic fat measurements included intraorgan adipocyte fat content because current methodology precludes assessment of the more mechanistically important islet intracellular fatty acid content. Animal data suggests the two variables are linked.
- Participants selected to have a relatively short duration of Type 2 DM (up to 4 years). Further studies must establish the extent of reversibility with longer duration Type 2 DM.
- Observations made after 12 weeks of return to a normal diet limited.
- The G allele of the PNPLA3 gene determines high liver fat levels, but in a form that is not associated with metabolic abnormality. Provides a clear genetic basis for the observed individual variation in susceptibility to insulin resistance despite raised liver fat content, and offers a partial explanation of the overlapping hepatic fat levels in type 2 diabetic and control groups. Likely other genetic factors yet to be defined.
-
Conclusions
- Normalisation of both beta cell function and hepatic insulin sensitivity in Type 2 diabetes achieved by dietary energy restriction alone. Associated with decreased pancreatic and liver triacylglycerol stores.
- Abnormalities underlying Type 2 Diabetes reversible by reducing dietary energy intake.

The DIETFITS Randomized Clinical Trial (The Diet Intervention Examining The Factors Interaction with Treatment Success) JAMA 2018
By Gardner, Trepanowski , Del Gobbo
Objective
To determine the effect of a healthy low-fat diet versus a healthy low-carbohydrate diet on weight
change, and to determine whether genotype pattern or insulin secretion are related to the dietary
effects on weight loss.
Study design
12-month randomized clinical trial
Sample population
N = 609 adults (18–50 years old) without diabetes with a body mass index (BMI) of 28–40.
Location/venue
Not specified
Intervention
Health educators delivered the behaviour modification intervention to the healthy low-fat participants, (N = 305) and the healthy low-carbohydrate participants, (N = 304) via 22 diet-specific small group sessions administered over 1 year.
Control group
N/A
Outcome(s) of interest
• Effects of a healthy low-fat diet vs a healthy low-carbohydrate diet on weight change
• Relationship of genotype pattern or insulin secretion to dietary effects on weight loss
Summary of methods and intervention
N = 609 overweight adults. Participants were randomized to the 12-month healthy low-fat (HLF);
(N = 305) or healthy low-carbohydrate (HLC); (N = 304), diet.
Key results
• Among 609 participants, 244 (40%) had a low-fat genotype; 180 (30%) had a low-carbohydrate genotype; mean baseline INS-30, 93 μIU/ml
• For the healthy low-fat versus healthy low-carbohydrate diets, respectively:
•The mean 12-month macronutrient distributions were: 48% vs 30% for carbohydrates; 29% vs 45% for fat; and 21% vs 23% for protein.
•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 (mean between-group difference, 0 .7 kg [95% CI, −0 .2 to 1 .6 kg], or 1 .5 lbs [95% CI, −0 .4 to 3 .5 lbs]). This difference in weight loss was not statistically significant.
•No significant diet-genotype pattern interaction (P = 0 .20) or diet-insulin secretion (INS-30) interaction (P = 0 .47) with 12-month weight loss.
•Eighteen adverse or serious adverse events were evenly distributed across the two diet groups
Limitations
• 481 (79%) completed the trial.
• 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. It is possible there were confounding factors. For instance, it could be that for the range of macronutrients consumed in this study there is no difference in the interaction, or that the study was underpowered and therefore unable to detect a small difference.
• It is impossible to identify the effect of a gene (genotype) without measuring the epigenetic state and knowing if the gene is active or quiescent. The epigenome was not assessed in this study, a major limitation in any genotype association study.
Strengths
Health educators delivered the behaviour modification intervention to both groups via 22 diet-specific small group sessions administered over 1 year. The sessions emphasized diet quality and focused on ways to achieve the lowest fat or carbohydrate intake that could be maintained long-term.
Key conclusions
There is considerable scientific interest in identifying the genetic variants that help explain inter-individual differences in weight loss success in response to diet interventions, particularly diets with varying macronutrient compositions. In this 12-month weight loss diet study, there was no significant difference in weight change between a healthy low-fat diet versus a healthy low-carbohydrate diet. Also, neither genotype pattern nor baseline insulin secretion was associated with the dietary effects on weight loss. In the context of these two common weight loss diet approaches, neither of the two hypothesized predisposing factors was helpful in identifying which diet was better for whom. Significance for lifestyle medicine
Dietary modification remains key for successful weight loss, yet no one dietary strategy is consistently superior to another for the general population. Previous research suggests genotype or insulin-glucose dynamics may modify the effects of diets. This study demonstrates that epigenetics must be part of the measures assessed in lifestyle diet intervention studies. Diet determines the expression of many genes.

DiRECT trial
Population
- adults, NIDDM < 6 yrs w BMI 27-45, not on insulin
- n = 306 from 49 practices.
Design: Open label cluster RCT at 49 1’ care practices in
Scotland & England (statistician blinded)
Intervention
1) Withdraw anti-diabetic and BP drugs
2) Total diet replacement (850 cal/d) with liquid formula x 3-5 months then stepped food reintroduction (2-8 wks) &
structured support for LTM weight loss maintenance
Control: best-practice care by guidelines
Outcome: Wt. loss > 15 kg & Remission of DM (HbA1c <
6.5% after at least 2 months off all diabetic meds
Results: 1) Mean decrease in weight: 10.0 vs 1.0 Kg -
delta 8.8 Kg (P<0.0001)
a) Loss of > 15 kg in 24% v 0%; P<0.0001
2) QOL (EuroQol VAS) improved by 7.2 points vs decrease by 2.9 points. (delta 6.4 points; p=0.0012)
3) DM remission 46% vs 4%, OR 19.7; P<0.0001
4) Primary predictor of remission was weight loss:
- none in those who gained weight.
- 86% in those who lost 15kg or more
Comparison with Lookahead:
Overall Direct had a 46% remission rate for NIDDM vs 11.5% (both at 1 yr) in Lookahead (& 2% on ADA diet)
- due to differences in dosing strength (1,200-1,800 cal/d in Lookahead vs 850 cal/d in Direct).
- used a low energy liquid replacement diet.
Fasting Mimicking Diet
Aim: To examine whether cycles of the FMD are able to
promote the generation of insulin-producing B cells
Fasting mimicking diet in mice:
a) FMD induces stepwise expression of Sox17 and Pdx-1
b) followed by Ngn3-driven generation of insulin-producing beta cells resembling that observed during pancreatic development.
c) In mice w NIDDM & IDDM, FMD cycles restore insulin
secretion and glucose homeostasis.
Fasting mimicking diet on humans
a) In human IDDM islet cells, FMD
reduce PKA and mTOR activity and
induce Sox2 and Ngn3 expression and insulin production.
b) The effects of FMD are:
Reversed by IGF-1 treatment
Recapitulated by PKA and mTOR inhibition
Fasting mimicking diet on mice & humans:
1) A FMD reverses IDDM and NIDDM phenotypes
in mouse models
2) A FMD promotes the reprogramming of
pancreatic cells to restore insulin generation in islets from
IDDM patients
FMD for humans:
1a) Calories: day 1 = 1100 cal, day 2-5 = 720 calories
1b) % calories: Protein 10%, fat 45%, CHO 45%
2) The human FMD comprises formulations of vegetable based soups, bars & snacks plus an algal oil capsule.
Diabetes Care to Cure
A major reason lifestyle measures (LS) aren’t used in clinical practice is that it’s difficult for patients to sustain the changes due to lack of support and the many counteracting stimuli from environmental pressures.
Multiple changes of the health system need to be made
focusing on patient self-empowerment.
These include:
1) Making a 360’ diagnosis (determine all the relevant
biological, sociological, psychological, contextual
conditions of the patient).
2) Identifying the trajectory toward disease
3) Achieving a sustainable and perceivable
lifestyle change
4) Motivational tools are required in the form of personal
coaching and IT/communications support
NIDDM is a genotype-environment interaction disease.
- environment: wrong diet, inadequate [exercise],
disrupted sleep, too much stress
The articles authors provide evidence for the reversibility of insulin resistance & the remission of NIDDM by diet &
lifestyle.
They assert that complete cure may be achieved if:
1) Beta cell function is still appropriate
2) Complications have not yet occurred

What do you Hear in your internal dialogue?
Analyse your internal dialogue: any cognitive distortions?
Reconstruct your thinking: write factual statements to replace distorted thinking.
Practice: to eliminate distorted thinking.
takes a lot of practice…
10 Examples Non productive Thinking or cognitive distortions
- All or Nothing Thinking: i have not accomplished anything since i have been in graduate school
- Overgeneralisation: he never washes his dishes
- Mental Filter: my boss’ review of full of criticism
-
Mind Reading: i know my partner think i did a terrible job on that presentation
5.Fortune Telling: i will probably just mess up and make a fool of myself. -
Magnification/Minimisation: i haven’t accomplished anything since i’ve been in medical school.
7.Personlisation and blame: that jerk just cut me off and made me spill my coffee they just ruined my day.
8.Emotional Reasoning: i feel like an idiot so i really must be one. - Labelling/Mislabelling: i am such a disorganised person.
- Disqualifying the positive: giving up caffeine may have benefits but those benefits will be worthless since i might have a headache for a few days.
ABCDE Model of Dr Albert Ellis to identify and reframe non productive thinking
A: what Action or Event occurred
B: what Beliefs do you have about what happened
C: What are the Consequences of those beliefs? how does it make you feel?
D: how can you Disrupt those beliefs that seem to be distorted and unhealthy?
E: what Effect does this new way of thinking have on how you feel and how you will move forward?
- What are the 3 approaches within positive psychology?
- What are 4 benefits of this approach?
- APPROACH
emphasizes patient’s current skills and abilities, strengths and positive actions (and associated successes)
Values positive emotions, engagement relationships and meaning
- healthy ratio of positive to negative
- BENEFITS
Builds patient’s confidence
Reinforces autonomy and self efficacy which are keys to sustainable self management.
Enhances resiliency and helps undo negative feelings.
Increases the positivity of the patient-provider interaction.
life style prescription vs action plan
lifestyle prescriptions are brief, clear instructions for care or treatment pertaining to an individual patient
prescriptions describe the action or behaviour change in the full extent necessary to treat or prevent.
e:g a prescription for 150 minutes of moderate PA for a week.
action plan: the life style prescription is adjusted and personalized for the patient’s ability, readiness and confidence.
e:g of action plan: start with walking 5 minutes a day for 5 days a week increased as tolerated up to the recommended amount of 150 minutes per week.
What are the three components of motivation?
Importance, relevance, readiness
Define the 5 components of a SMART goal:
specific: identify the exact behaviour to be addressed
measurable: how one will know when the goal is reached.
Attainable: the goal is achievable and can be accomplished with current resources
Relevant: the goal is in alignment with the specific behaviour change
time-bound: the time frame for achieving that goal.
3 questions for maintenance of action plan
what benefits have you gained from the changes you have made
what have you learnt from the challenging areas
how do you feel about your situation.

assist: the patient in achieving goals to change practices, address motivational barriers via counselling, if needs additional info or help, refer to dietitian
arrange: regular follow up and support.
In relation to the evidence base for effective coaching that promotes health behaviour change and improves health outcomes, which of the following is/are not correct
A. a 2017/2019 systematic review published in AJLM showed the most consistent effects of health and well being coaching were observed in both exercise and nutrition behaviour. Health coaching also improved HbA1c, weight reduction and BMI
B. systematic review of 35 studies results: 73% trials showed that intervention did alter provider/patient interaction. Health outcomes were positively affected in 44% trials and negatively affected in 20% trial
C. Physician’s with high empathy scores from their patient were less likely to achieve good HbA1c control than those with low empathy scores.
D. Ten hours of provider training on empathy skills can achieve similar empathy results as those providers who have had longer training on empathy.
E. Health outcomes for HT, glucose levels and functional status are NOT related to the patient-provider relationship.
Answer C and E
C Physician’s with high empathy scores from their patient were more likely to achieve good HbA1c control than those with low empathy scores ( 56% vs 40%)

Answer C and E
C be empathic
E share where disclosure will be beneficial to the patient.
Self motivation is also known as autonomous or internal motivation.

Screening and diagnostic tests in LM
U&ES LFTs Blood Glucose, Blood proteins, Acid base balance, FBC Fasting lipids ( TC, HDL-C, LDL-C, TG, High sensitivity CRP). HbA1c, OGTT, Fasting serum insulin, possibly c peptide, Homeostatic model assessment for insulin resistance ( HOMA-IR) Vitamin D, TFTs.
If the TC is <150mg/dl or 3.879 mmol/L the risk of heart disease is low.
LDL-c Friedewald equation LDL=TC-HDL- (TG*2) not validated if TG is >400 ( 4.516mmol/L)
particle size has been shown to help stratify risk. particle density alone doesnt completely describe the role and function of cholesterol fractions.
TG elevation is often associated with low HDL and increase girth waist circumference.
C peptide is used to assess endogenous insulin production in order to identify how well b-cell are functioning to meet demands of insulin production. its used to determine if patient has type 1 or type2 DM.
HOMA-IR is an estimate of insulin sensitivity and beta cell function based on the fasting plasma glucose concentration, fasting plasma insulin or c peptide measurements.
lab testing for diabetes based on evidence based national guidelines.
Diabetes
HbA1c of >6.5% but this diagnose 1/3 fewer cases of undiagnosed diabetes then looking at fasting plasma glucose test

What are 6 benefits of GROUP VISITS?
(includes shared medical appts, drop-in group)
- improved access to care
- increased patient adherance, satisfaction, lower hospiltalization rates, higher trust in providers, improved access for complex and elderly patient, better monitoring, received greater education from group discussions and peer support, improved access, gain additional choices in their care treatment options) and
- provider satisfaction (more efficient use of time, enhances quality, outocomes patients’ health experiences while containing cost and improving income, something different interesting and fun, reduces repitition allows more time and more frequent contact with patients, Group support and collaborative care is helpful in managing difficult, time consuming and psychologically needy patients)
- reduce cost. among uncontrolled type 2DM patients group visits reduce total health care expenditure cost by ~30%
- group visits also increases physician’s productivity.
- billiable when billing criteria are met.

- four health risk behaviours: tobacco use, Risky alcohol use, unhealthy diet, lack of PA.
- findings- **primary care offices were capable and wanted to address health behaviour when funding and support were available via PBRNs.
- **health care delivery model such as patient centre medical home was important.
- *substantial practice design needed to occur with the integration of public health and community resources.
- dozens of studies were published
- prescription for health toolkit not accessible now.

Scientific data supporting that physicians who practice healthy lifestyle are more likely to offer counselling and patient outcomes.
Physician’s personal health behaviours.
2009 survey of californian physicians: number 763
severe to moderate stress: 53%
no or occasional exercise 35%
6 or few hours of sleep 34%
never or occasionally ate breakfast 27%
sedative/tranquilizer use 13%
depression 7%
Marijuana use 4%
2012 survey 53% of primary care physicians were obese.
in 2013 36% of canadian 4th year medical students surveyed didnt meet PA guidelines
in 2013 article overweight resident physicians under acknowledged their overweight status and their under- acknowledgement increased by training year.
other studies have found physicians are practising healthy behaviours therefore arguing against unhealthy doctors’
in 2000 study in men, mortality outcome suggest that physicians live longer than same race professionals and non professional in the US population.
in 2015 study: physicians and medical students engage in more PA than the general US adult population.
Physician’s personal health and attitudes impact patient care
A. in Life style medicine 3rd edition 2019 by J Rippe. Erica Franks says
1. providers need to focus on their own health.
2.healthy doctors are more likely to produce healthy patients.
B. meta-analysis of 24 studies high correlation between physician’s PA habits and counselling frequency odds of counselling 1.4-5.7 times higher among the exercising physicians.
C. Cross sectional study on 1349 internists
Male internists: with smoking, alcohol, seat belt use, and PA were positively associated with counselling for each health behaviour except alcohol use.
Female: with PA positively associated with counselling patients about exercise and alcohol use.
D. physician who exercise( aerobic and strength) are more likely to counsel patients on exercise than who dont
E.physician attempting to chase their own poor habits counsel more
F. training primary care physician in behavioural counselling and providing them with tools and resources helps in their practice of weight related care.
G. in 2014 study physician and medical student with normal BMI felt confident about counselling their patients about PA.
H. non smoking physician emphasize the risk of smoking.
I physician more likely to record diagnosis of obesity and initiate a conversation if they perceived patient weight to be more than their own.
J. female physician’s personal health practices, counsel of behaviour change at least once a year= if they ate less fat counsel on cholesterol, if ate five fruit and veg per day they counsel more on nutrition, if consumed veg diet counsel on weight loss and nutrition.
K. poor physician health habits impact counselling they provide to their patients.
L. The American Medical association code of medical ethics’’ physician health and wellness’’ physicians have responsibility to maintain their health and wellness for safety and effectiveness of the medical care they provide.
M. Physicians are high risk of burn out: which is syndrome of high emotional exhaustion, high depersonalization and a low sense of personal accomplishment from work.
2019 consensus study by national medical academy NAM report US 35-45% on nurses and physicians have substantial symptoms of burnout. medical students 45-60%.
suboptimal care for patient may be one of the unintended consequences of physician burnout.
NAM suggests interventions to prevent and reduce burnout need to be both individual based and organisationally focused strategies.

When counseling patients on physical activity, one approach is to use the 5A’s. What is the correct order that these steps should be delivered in?
A) Ask, assess, assist, agree, arrange
B) Ask, assess, assist, advise, arrange
C) Assess, advise, assist, arrange, agree
D) Assess, advise, agree, assist, arrange
E) Ask, advise, assist, agree, arrange
D. The correct order is: assess, advise, agree, assist, arrange.
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.
and for tobacco or intervention counseling are Ask, Advise, Assess, Assist, and Arrange.
With regard to pre-participation screening, what are the major disease entities one needs to consider when deciding whether additional medical clearance is needed?
- Cardiovascular disease
- Pulmonary disease
- Renal disease
- Metabolic disease
A) 1, 3 and 4
B) 1 and 2
C) 1
D) 1, 2 and 3
E) All of the above
A. 1, 3 and 4.
Referral to a health provider should be made on the basis of current physical activity levels and presence of signs or symptoms and/or known cardiovascular, metabolic or renal disease. While one might modify an exercise prescription for someone with pulmonary disease, pulmonary disease alone does not require medical clearance, as it has not been shown to increase the risk of cardiovascular complications.
[Riebe D, et al. Updating ACSM’s Recommendations for Exercise Preparticipation Health Screening. 2015;47:2473-2479.]
When using the Talk Test as an exercise intensity measure, a patient performing vigorous-intensity exercise is able to _____.
A) Sing but not talk
B) Talk but not sing
C) Sing or talk
D) Barely talk
E) None of the above
D. Barely talk
The Talk Test is an intensity measure that’s easy for patients to perform on their own.
Very light or light activity should allow patients to talk and/or sing without difficulty (HR 63% or less of maximal).
Moderate exercise (64 to 76% of maximal) should allow individuals to talk but not sing (Answer C).
Vigorous to maximal exercise (77 to 100% of maximal) should make it difficult for an individual to talk or hold a conversation.
[Persinger R, et al. Consistency of the talk test for exercise prescription. Med Sci Sports Exerc, 2004. 36(9): p. 1632-6.]
Who should be referred to a health provider for medical clearance prior to starting a moderate- intensity exercise program?
A) A 45-year-old male who has no known cardiovascular, metabolic or renal disease, and who does not currently participate in regular exercise and is asymptomatic.
B) A 55-year-old male who has known cardiovascular disease, currently participates in regular exercise and is asymptomatic.
C) A 30-year-old female who has known diabetes, does not currently participate in regular exercise and is asymptomatic.
D) More than one of the above.
E) None of the above.
C. A 30-year-old female who has known diabetes, does not currently participate in regular exercise and is asymptomatic.
An asymptomatic male with no known cardiovascular, metabolic or renal disease does not require medical clearance before beginning a moderate-intensity or vigorous-intensity exercise program.
An adult with known cardiovascular, metabolic or renal disease who is already participating in regular moderate-intensity exercise and is asymptomatic does not need a referral for moderate-intensity exercise. However, a referral is recommended if they want to pursue vigorous-intensity exercise.
It’s recommended that an adult with known cardiovascular, metabolic (e.g., diabetes), or renal disease who does not currently exercise should be referred for medical clearance, even if they are asymptomatic.
Any symptomatic individual should be referred for medical clearance.
[Riebe D, et al. Updating ACSM’s Recommendations for Exercise Preparticipation Health Screening. 2015;47:2473-2479.]
For 5% weight loss, many people need to do more than _____ per week of moderate-intensity activity.
A) One hour and 15 minutes
B) Two and a half hours
C) Five hours
D) Seven hours
C. Five hours.
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.
[CDC. 2008 Physical Activity Guidelines. Active Adults. 2008. [2/25/18]; Available from https://health.gov/ paguidelines/guidelines/chapter2.aspx.]
