The correct question is:
What is exercise?
What is fasting?
What is purging?
- Exercise is a safe way to lose weight. Walking, running, swimming, bicycling, aerobic dance
and other physical activities burn up calories.
- When you fast, you stop eating entirely. Without food, your body
won't get the nutrients it needs. Fasting can be dangerous.
- With purging, a person intentionally vomits or uses laxatives or diuretics to lose weight.
This dangerous practice harms the body and can even kill you.
