Gynoid
Waist to hip ratio for significant health risk in men and women?
Men = >/ .95 Women = >/.80
These lead to a potential for obesity?
- Low EE
- High energy intake
- Genetic and parental influence

Negative energy balance
Do obese people eat more?
Controversial
Studies indicate that obese people --- caloric intake --- physical activity Choose more ---- food Have different -----
- Underestimate
- Overestimate
- High fat
- Eating behaviors
Energy to maintain life and normal body functions?
Resting metabolic rate
RMR varies among the same?
Age, sex, body weight
Higher FFM = higher ?
Higher RMR
Glycemic index:
Low, moderate, high
Low = 60
Too much protein causes — and excessive production of —?
Dehydration, urea
Why is treatment of obesity a tremendous challenge?
- Many will not stick to workout
- Many will not achieve goal BW
- Most who lose weight will gain it back
- Not successful long term
To reach optimal health how many calories should be burned through planned exercise?
200-400cals
How many minutes of PA are recommended per day?
30 mins/day
This is 10% of energy in the body, it increases in EE above RMR and can be measured several hours after a meal?
Thermic effect of food
How much total daily energy do you get from RMR?
60-75%
What decreases in direct relationship to obesity?
Physical activity
Why should a diet include at least 58-70% carbohydrate?
- Maintain normal nervous system function
- Prevents glycogen depletion
- Restricted carbs = ketone bodies
Why do low carb diets produce such rapid weight loss?
Low carbs = depletion of glycogen stores, which gets rid of the water in the body
Are low carb diets safe?
No, blood PH levels get dangerously lose and fatigue, hypoglycemia, ketosis are common
Are high-protein diets safe?
They promotes muscle tissue loss and can be hard on kidneys
Are diets with a low GI safe and effective way to lose weight?
More research is needed, it makes you feel full w/o consuming excess calories
What is the danger of fasting or skipping meals to promote weight loss?
It causes the body to store more fat, and when the fat is gone it starts taking protein from your body
What are the conservative ways to lose weight?
- Diet
- Exercise
- Behavior modifications
What are the non-conservative ways to lose weight?
- Drug therapy
2. Surgery
What drugs are FDA approved to lose weight?
Meridia, Orlistat, Belvia, Qsymia

10% reduction
According to NHLBI: wight loss should be —lbs (— cal/day) deficit by decreasing caloric intake —- cals and increasing PA by — cals?
- 1-2lbs
- 500-1,000
- 300-600
- 200-400
What behavior modifications should be made to lose weight?
- Self monitor dietary habits
- Control events that precede eating
- Control act of eating
- Be wise and think positive
- Have rewards (that aren’t food)
What are the pyramid/ my plate weight management guidelines?
Low saturated fat, low salt, lower sugar intake, alcohol in moderation
Food intake must be over – for men and – for women for it to be a good weight loss program
1600, 1200
How do you find RMR in men and women?
Men: BW x 11 kcal/lb
Women: BW x 10 kcal/lb
Exercise does not counter – and —?
Diet induced decrease in RMR and diet induced decrease in FFM
