You can either be underweight or overweight.
Metabolism
Total of the chemical reactions that are going on in your body
Affected by
- Amount of exersise you do
- Genetics
- Muscle to fat ratio (muscle requires energy)
- Gender (females tend to have lower)
Cholesterol
Required in the body to make cell membranes
Too much can lead to blocked arteries (especially around the heart), restricting the blood flow
This can lead to a heart attack.
Type 2 diabetes

Means you cannot control blood sugar levels
Insulin is not recognised by body cells so cells don't take sugar out of the blood.
