impact of physical activity on obesity, diabetes and cancer Flashcards
_____behaviors are the primary contributors to obesity
self-selected
self sleeted behaviors that lead to obesity
poor diet, sedentary lifestyle, excessive alcohol, poor sleep, unmanaged stress
high sugar/processed carbohydrates consumption causes
hyperglycemia and consequent hyperinsulinemia
when excess insulin is present it
promotes sugar conversion in the liver and blocks lipid oxidation leading to weight gain over time
fit-healthy body fat for males
<20%
fit-healthy body fat for females
<26%
stage 1 obesity in males
> 25%
stage 1 obesity in females
> 32%
stage 1 obesity in old age
> 38%
stage 2 obesity males
> 30%
stage 2 obesity females
> 40%
stage 3 obesity males
> 35%
stage 4 obesity females
> 45
high risk obesity waist circumference males
> 40in waist
high risk obesity waist circumference females
> 35 in waist
high risk obesity BMI
> 30
morbid obesity BMI
> 35
4 things obesity is associated with
mental health issues, reduced quality of life and physical function, increased risk for sleep apnea, metabolic syndrome, osteoarthritis, autoimmune disorders, increased risk for all-cause death
high visceral fat promotes
low grade systemic inflammation which leads to insulin resistance, hyperinsulinemia, atherosclerosis, hormonal/metabolic dysfunction
hormones that regulate hunger
leptin
hormones that communicate energy needs
adipokines
______ can cause hunger without the need for calories and additional eating
dysfunction of hormones that regulate hunger and communicate energy needs
visceral fat
fat that surrounds the internal organs in the abdominal region
hyperinsulinemia
excess levels of circulating insulin
hyperinsulinemia indicates
progressive insulin resistance as a precursor to diabetes
hyperinsulinemia increases
fat storage
combination of aerobic/anaerobic exercise can positively impact obesity via
improved insulin sensitivity, heightened caloric expenditure for body fat losses
potential mediation of systemic inflammation and hormone disfunction
is physical activity enough for obesity
no
diabetes mellitus
chronic disease involving an inability to. properly manage blood glucose
type one diabetes mellitus
autoimmune disease characterized by pancreatic atrophy and dysfunction due to compromised beta cells which results in an inability to produce insulin; hereditary usually in early life
