Question 1

Which macronutrient has the highest thermic effect of food (TEF), meaning the body burns the most calories digesting it?

Accepted Answer

Protein

Answer

Protein has a thermic effect of approximately 20–30%, meaning the body uses more energy to digest and metabolize it compared to carbohydrates (5–10%) or fat (0–3%).

Question 2

A caloric deficit is necessary for fat loss. How large a deficit (in calories) theoretically yields one pound of fat loss per week?

Accepted Answer

3,500 calories

Answer

One pound of fat contains roughly 3,500 calories, so a 500-calorie daily deficit over seven days equals approximately one pound of fat lost per week.

Question 3

Which dietary approach cycles between periods of eating and fasting to promote fat oxidation?

Accepted Answer

Intermittent fasting

Answer

Intermittent fasting restricts eating to defined windows, depleting glycogen stores and shifting the body toward fat oxidation during fasting periods.

Question 4

Which type of dietary fat, found in fatty fish and flaxseed, is associated with improved insulin sensitivity and enhanced fat metabolism?

Accepted Answer

Omega-3 fatty acids

Answer

Omega-3 fatty acids help reduce inflammation and improve insulin sensitivity, creating a hormonal environment more conducive to fat burning.

Question 5

Adequate hydration supports fat burning primarily because water is required for which metabolic process?

Accepted Answer

Lipolysis (fat breakdown)

Answer

Lipolysis, the breakdown of triglycerides into free fatty acids and glycerol, requires water as a reactant in hydrolysis reactions.
