A
  1. Know the average caloric needed per day
  2. Low-fat, high-fiber approaches
  3. No diet has a “metabolic advantage”
  4. Read and use food labels
  5. Control hunger

Energy can never be created nor destroyed

30
Q

What is the fat accumulation theory of overweight/obesity?

A

Overweight and obesity are not energy balance problems, they are fat accumulation problems

31
Q

According to the fat accumulation theory, what causes increased fat accumulation?

A

High insulin

32
Q

According to the fat accumulation theory, what causes high levels of insulin to be released?

A

High carb diets

33
Q

According to the fat accumulation theory, what would be the solution to the overweight/obesity problem?

A

Decrease the amount of insulin we secrete or increase our insulin sensitivity

34
Q

When the typical person feels hunger, what they are really experiencing?

A

Low blood suger

35
Q

What are the 4 main arguments against low carb diets?

A
  1. It causes ketosis
  2. The brain needs sugar
  3. It’s low in fruits and vegetables and thus nutrients
  4. The saturated fat and cholesterol problem
36
Q

Why are the 4 main arguments against low carb diets wrong?

A
  1. The diet does not have to be ketogenic to cause weight loss
  2. Your liver produces carbs
  3. Many fruits are fairly low in sugar, you may have to cut out very sugary fruits
37
Q

What are 4 other factors besides insulin that promote fat accumulation in the body?

A
  1. Stress
  2. Inflammatory diet
