Answer:
Because of structure and timing
Step-by-step explanation:
What I mean by structure and timing is that:
- Fad diets only make people look good, or attracts people because of the lifestyle. There isn't anything very good about fad diets according to actual health and science, but it attracts people to lose weight by the looks.
- Most fad diets only work for a limited time due to them not lowering your body fat, but just lean muscle and water for a short amount of time.
Hope it helped.
