Weight Loss Knowledge 3 — Questions and Answers
Question 1: Which eating pattern involves alternating between periods of eating and fasting within a day or week?
- The DASH diet
- Intermittent fasting (Correct answer)
- Carbohydrate cycling
- Volumetrics diet
Correct answer: Intermittent fasting
Intermittent fasting structures eating into defined windows, which can reduce total calorie intake for many people.
Question 2: What term describes the total number of calories burned through all movement that is not formal exercise, such as fidgeting and walking?
- REE
- TEF
- NEAT (Correct answer)
- BMI
Correct answer: NEAT
Non-Exercise Activity Thermogenesis (NEAT) accounts for a significant and highly variable portion of daily energy expenditure.
Question 3: Which nutrient is essential to prioritize during weight loss to prevent muscle loss and support metabolism?
- Simple sugars
- Saturated fat
- Protein (Correct answer)
- Sodium
Correct answer: Protein
Adequate protein intake during a caloric deficit helps preserve lean muscle mass and keeps metabolism from declining as much.
Question 4: What is 'metabolic adaptation' in the context of long-term dieting?
- The body burning more calories as you lose weight
- A reduction in metabolic rate beyond what weight loss alone predicts (Correct answer)
- Increased fat absorption from food over time
- Faster digestion of carbohydrates
Correct answer: A reduction in metabolic rate beyond what weight loss alone predicts
Metabolic adaptation is the body's compensatory downregulation of calorie burn, making continued weight loss progressively harder.
Question 5: Which popular diet strategy emphasizes very low carbohydrate intake to shift the body into a fat-burning state called ketosis?
- The Mediterranean diet
- The ketogenic diet (Correct answer)
- The Ornish diet
- The flexitarian diet
Correct answer: The ketogenic diet
The ketogenic diet restricts carbs to typically under 50g/day, prompting the liver to produce ketones from fat for fuel.
Question 6: What does the concept of 'energy balance' mean in weight management?
- Eating equal amounts of each macronutrient
- The relationship between calories consumed and calories burned (Correct answer)
- Matching meal timing to workout schedules
- Balancing electrolytes in the diet
Correct answer: The relationship between calories consumed and calories burned
Energy balance — calories in versus calories out — is the foundational principle determining whether someone gains, loses, or maintains weight.
Question 7: Which body composition measurement is most commonly used to assess health risk beyond just body weight?
- Total body weight
- Waist circumference (Correct answer)
- Shoe size
- Resting heart rate
Correct answer: Waist circumference
Waist circumference correlates with visceral fat, which is strongly linked to metabolic disease risk independent of total weight.
