Explanation:

• For question 20: Taking excessive supplements can lead to toxicity, organ damage, and imbalance in the body.
• For question 21: Age affects metabolic rate and nutrient requirements (e.g., children vs. adults). Gender influences muscle - fat ratio and hormonal needs. Activity level impacts calorie and nutrient (like protein for muscle repair) demands. Preferences do not directly affect nutrient needs but may affect intake.
• For question 22: Fad diets often severely restrict food groups, leading to nutrient deficiencies. They are usually unsustainable, causing weight regain. Some may have extreme calorie limits that harm metabolism.
• For question 23: A poor body image can cause a person to overly restrict food (e.g., anorexia nervosa to achieve an "ideal" body) or engage in binge - purge cycles (e.g., bulimia nervosa as a distorted way to manage body perception).

Answer:

1. True
2. Age, Gender, Activity Level
3. Fad diets are dangerous and ineffective because they often severely restrict food groups (causing nutrient deficiencies), are unsustainable (leading to weight regain), and may have extreme calorie limits (harming metabolism).
4. A poor body image might result in an eating disorder as a person may overly restrict food (e.g., anorexia) to achieve a perceived ideal body or engage in binge - purge cycles (e.g., bulimia) as a distorted way to manage body perception.
