Fat Burning Fat Burning Exercise and Training Methods 1 — Questions and Answers
Question 1: High-Intensity Interval Training (HIIT) promotes fat burning after the workout through a phenomenon known as:
- Excess Post-Exercise Oxygen Consumption (EPOC) (Correct answer)
- Glycogen supercompensation
- Anabolic window effect
- Steady-state oxidation plateau
Correct answer: Excess Post-Exercise Oxygen Consumption (EPOC)
EPOC (the 'afterburn effect') describes elevated oxygen consumption and calorie burning that continues for hours after high-intensity exercise ends.
Question 2: The 'fat-burning zone' during cardio exercise typically corresponds to what percentage of maximum heart rate?
- 60–70% (Correct answer)
- 85–95%
- 45–55%
- 100%
Correct answer: 60–70%
At 60–70% of maximum heart rate, the body uses a higher proportion of fat as fuel, although total caloric burn is lower than at higher intensities.
Question 3: Resistance training supports long-term fat loss primarily because it:
- Increases lean muscle mass, raising resting metabolic rate (Correct answer)
- Burns more calories per session than all cardio forms
- Completely suppresses cortisol production
- Eliminates the need for dietary changes
Correct answer: Increases lean muscle mass, raising resting metabolic rate
Building lean muscle through resistance training raises resting metabolic rate because muscle tissue requires more energy to maintain than fat tissue.
Question 4: Performing cardio in a fasted state (e.g., before breakfast) is theorized to enhance fat oxidation because:
- Glycogen stores are lower, so the body relies more on fat for fuel (Correct answer)
- Cortisol is at its daily low point in the morning
- Insulin levels are elevated, promoting lipolysis
- Muscle protein synthesis is highest after fasting
Correct answer: Glycogen stores are lower, so the body relies more on fat for fuel
Overnight fasting depletes some liver glycogen, and lower insulin levels during fasting allow greater access to stored fat for energy during exercise.
Question 5: Which type of cardio exercise—performed at a sustained, moderate pace—is sometimes called 'steady-state cardio' and is effective for burning fat?
- Low-Intensity Steady-State (LISS) cardio (Correct answer)
- Tabata intervals
- Plyometric circuits
- Sprint intervals
Correct answer: Low-Intensity Steady-State (LISS) cardio
LISS cardio, such as brisk walking or light jogging sustained for 30–60 minutes, keeps heart rate in the aerobic fat-burning zone and is easy to recover from.
Question 6: Non-Exercise Activity Thermogenesis (NEAT) contributes to daily caloric expenditure by encompassing:
- All physical movement outside formal exercise (e.g., walking, fidgeting, household tasks) (Correct answer)
- Only structured gym workouts
- The calories burned during sleep
- Digestive processes and organ function
Correct answer: All physical movement outside formal exercise (e.g., walking, fidgeting, household tasks)
NEAT can account for 15–50% of total daily energy expenditure and is a highly variable component that significantly impacts fat loss outcomes.
