Question:

What are the side effects of very Low-Calorie Diets?

Answer:

People on a very low-calorie diet for 4 to 16 weeks report minor side effects such as:
- Fatigue,
- Constipation,
- Nausea
- Diarrhea

These conditions usually improve within a few weeks and rarely prevent people from completing the program. Gallstones are the most common serious side effect of very low-calorie diets. Gallstones are more common during rapid weight loss. When the body experiences a calorie deficit, it starts to break down fat for energy. The liver then secretes more cholesterol and when combined with bile, can form gallstones.
