What is a Diet Plan?
A diet plan is a structured and goal-based eating system that defines the following:
- What you should eat
- How much you should eat

It is designed to support your specific fitness or health goal, such as weight loss, muscle building, or improving energy levels.
A good diet plan ensures that your body receives the right balance of
- Protein
- Carbohydrates
- Healthy fats
- Vitamins & minerals

4. Prevents Diseases
Proper diet reduces the risk of:
