Weight Loss Weight Loss Nutrition 2 — Questions and Answers
Question 1: Which type of dietary fat is most associated with increased abdominal fat storage and cardiovascular disease risk?
- Monounsaturated fat
- Polyunsaturated fat
- Trans fat (Correct answer)
- Omega-3 fat
Correct answer: Trans fat
Trans fats (partially hydrogenated oils) increase LDL cholesterol, promote visceral fat accumulation, and significantly raise cardiovascular disease risk.
Question 2: What is the recommended daily water intake for an average adult that supports weight loss by promoting satiety?
- 1–2 cups
- 4–6 cups
- 8–10 cups (Correct answer)
- 15–20 cups
Correct answer: 8–10 cups
Drinking 8–10 cups (about 2 liters) of water daily supports metabolism, reduces hunger signals, and can decrease caloric intake when consumed before meals.
Question 3: Which hormone signals fullness to the brain after eating and is primarily produced by fat cells?
- Ghrelin
- Cortisol
- Leptin (Correct answer)
- Insulin
Correct answer: Leptin
Leptin is produced by adipose tissue and signals satiety to the hypothalamus, helping regulate long-term energy balance.
Question 4: What is the primary role of dietary fiber in weight management?
- Provide quick energy
- Increase caloric density
- Promote satiety and slow digestion (Correct answer)
- Stimulate insulin release
Correct answer: Promote satiety and slow digestion
Dietary fiber slows gastric emptying and digestion, promotes feelings of fullness, and reduces overall caloric intake by adding bulk without calories.
Question 5: Which beverage is most likely to contribute to hidden caloric intake and weight gain in American adults?
- Black coffee
- Unsweetened tea
- Sweetened sodas and juices (Correct answer)
- Sparkling water
Correct answer: Sweetened sodas and juices
Sweetened sodas and juices are a major source of added sugar and liquid calories that do not trigger the same satiety response as solid food.
Question 6: Which meal timing strategy is associated with better weight management outcomes in research on US adults?
- Eating the largest meal at night
- Front-loading calories earlier in the day (Correct answer)
- Skipping breakfast daily
- Eating every 30 minutes
Correct answer: Front-loading calories earlier in the day
Consuming more calories earlier in the day aligns with circadian metabolic patterns, improving insulin sensitivity and supporting weight loss.
