Fat Burning Fat Burning Nutrition and Diet 1 — Questions and Answers
Question 1: Which macronutrient has the highest thermic effect of food (TEF), meaning the body burns the most calories digesting it?
- Protein (Correct answer)
- Carbohydrates
- Fat
- Alcohol
Correct answer: Protein
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?
- 3,500 calories (Correct answer)
- 2,000 calories
- 1,200 calories
- 5,000 calories
Correct answer: 3,500 calories
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?
- Intermittent fasting (Correct answer)
- Carbohydrate loading
- Bulking phase
- Glycogen supercompensation
Correct answer: Intermittent fasting
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?
- Omega-3 fatty acids (Correct answer)
- Trans fatty acids
- Saturated fatty acids
- Omega-6 fatty acids
Correct answer: Omega-3 fatty acids
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?
- Lipolysis (fat breakdown) (Correct answer)
- Glycogenolysis
- Protein synthesis
- Gluconeogenesis
Correct answer: Lipolysis (fat breakdown)
Lipolysis, the breakdown of triglycerides into free fatty acids and glycerol, requires water as a reactant in hydrolysis reactions.
Question 6: Which eating pattern prioritizes consuming the majority of daily calories earlier in the day to align with circadian metabolic rhythms for fat loss?
- Time-restricted eating with front-loading (Correct answer)
- Late-night carbohydrate cycling
- Reverse dieting
- Ad libitum eating
Correct answer: Time-restricted eating with front-loading
Consuming larger meals earlier in the day aligns with peak insulin sensitivity and circadian metabolic activity, supporting more efficient fat burning.
