Waist circumference measurements - >44" for men
>32" for women
apple shape (android) - common in men
central obesity
pear shape (gynoid) - common in women
lower-body obesity
...estrogen falls, raises risk of chronic diseases
healthy weight lose = lb - 1 lb per week (~3,500 kcal)
what kind of diet is good for healthy weight loss? - low-fat, high fiber diet
Behavioral therapy techniques for healthy weight loss - chain-breaking
stimulus control (environment)
cognitive restructuring
contingency management (plan ahead)
self monitoring
when to use drugs or medication for weight loss - BMI of 30 or more
27-29.9 with weight loss related health conditions
Amphetamine (Phentermine) - decreases appetit
prolongs activity in the brain
Orlistat (Xenical) - reduces fat absorption by 30% in the small intestine
fat is deposited in the feces - can result in malabsorption of soluble fat vitamins
, Bariatric - surgery that focuses on treating obesity
severe
very-low cal diet - protein sparing modified fast (PSMF)
allows person 400-8000 kcal per day, often in liquids
adjustable gastric banding - opening from esophagus to stomach to is reduced by a
hollow gastric band
Gastroplasty - (stomach stapling)
limit volume of stomach to ~30 milliliters
Sleeve Gastrostomy - (gastric sleeve)
permanent surgical reduction of stomach by about 75%
Lipectomy - suctioning out through a thin tube
recommended tactics for healthy weight GAIN - increase intake of energy and nutrient
dense food (energy input)
Reduce activity (energy output), strength training

Recommended activity for the week - 150 minutes per week of MODERATE
INTENSITY
or
75 minutes per week of VIGOROUS INTENSITY
Aerobic vs. Anaerobic - aerobic - lower intensity, fuels prolonged
anaerobic - limited oxygen - intense physical activity
Aerobic Glycolysis - end product: breakdown of glucose - 95% of ATP made form
complete glucose metabolism
- liver glycogen released into bloodstream
2 mins to several hours of work
Anaerobic Glycolysis - produces more lactic acid
30 secs to 2 mins of work
Hydration recommendations - 9 cups per day for women
13 cups per day for men
fluid replacement after exercising - within 4-6 hours, consume 2-3 cups of fluid for every
pound lost
