"Some people fast as a way to lose weight. Others fast to try to detox their bodies, or for religious reasons.
If you're fasting to lose weight, you may want to reconsider. The weight loss may not last after you finish fasting.
If your goal is to detox your body, you should know that there's no proof that it works. Your body naturally detoxes itself.
Fasting diets aren't all the same. Some allow only liquids like water, juice, or tea.
