Weight Loss Weight Loss Nutrition 1 — Questions and Answers
Question 1: Which macronutrient has the highest satiety effect per calorie, helping reduce overall food intake?
- Protein (Correct answer)
- Carbohydrates
- Fat
- Fiber
Correct answer: Protein
Protein has the highest thermic effect and promotes satiety hormones like PYY, making it the most filling macronutrient per calorie.
Question 2: What is a caloric deficit required per week to lose approximately 1 pound of body fat?
- 1,750 calories
- 3,500 calories (Correct answer)
- 5,000 calories
- 2,500 calories
Correct answer: 3,500 calories
One pound of body fat contains approximately 3,500 calories, so a weekly deficit of 3,500 calories (500/day) yields roughly 1 lb of fat loss.
Question 3: Which dietary pattern is characterized by high intake of fruits, vegetables, whole grains, legumes, and olive oil, and is associated with sustained weight loss?
- Carnivore diet
- Mediterranean diet (Correct answer)
- BRAT diet
- Western diet
Correct answer: Mediterranean diet
The Mediterranean diet emphasizes whole foods and healthy fats, and research shows it supports long-term weight management and cardiovascular health.
Question 4: What does the glycemic index (GI) measure in relation to weight loss?
- Total calories in a food
- How quickly a food raises blood sugar (Correct answer)
- The fat content of food
- The fiber content of food
Correct answer: How quickly a food raises blood sugar
The glycemic index measures how quickly a carbohydrate-containing food raises blood glucose levels, with high-GI foods linked to increased hunger and fat storage.
Question 5: Which eating pattern involves cycling between periods of eating and fasting and has been shown to reduce caloric intake and promote weight loss?
- Grazing
- Intermittent fasting (Correct answer)
- Night eating
- Free feeding
Correct answer: Intermittent fasting
Intermittent fasting restricts the eating window, which naturally reduces caloric intake and may improve metabolic markers associated with weight loss.
Question 6: Which vitamin deficiency is commonly associated with obesity and metabolic dysfunction in the US population?
- Vitamin C
- Vitamin B12
- Vitamin D (Correct answer)
- Vitamin K
Correct answer: Vitamin D
Vitamin D deficiency is prevalent in obese individuals because fat tissue sequesters vitamin D, and low levels are linked to impaired fat metabolism.
