Diet- For a healthy diet you need to privide energy, just as long as it isn't too much.
You need a balance of different foods which provide different uses in the body

- Protein for growth, cell repair and replacment
- Fibre ti keep your digestive system running smoothly
- You also need vitamins and mineral ions to keep skin bones and everything else generally healthy.
You need energy to fuel chemical reactions in your body called your metabolism, they go at the speed of your metabolic rate.
people with larger muscle in their body will have a higher metabolic rate than those that contain more fatty tissue
The bigger you are, the higher your metabolic rate because your body needs more energy due to having more cells
Men have higher metabolic rate becasue they are bigger than woman and tend to have more muscles.
Exercise boots your resting metabolic rate becasue it builds muscle.
Your metabolic rate goes up during excercise becasue you need more energy, for example, people who have active jobs need more energy.
Your active level affects the amount of energy your diet should contain, so if you do little excercise you need to eat less fat and carbohydrate.
