A healthy and balanced diet during exercise is essential and will provide you with all the nutrients needed by the body to carry out physical activity.
Nutritional requirements in exercises

A diet low in carbohydrates results in lack of energy and low blood sugar levels.

The popular belief about proteins among those involved in physical exercises and body building is that it increases strength and enhances performance. Protein supplements are also taken by some athletes, however this should be discouraged as it puts additional stress on liver and kidneys.
In general the amount of proteins consumed by a normal individual is sufficient enough to meet the requirement of proteins during exercise and sports.
People involved in strenuous physical activities should consume 20-30% of their total calories from fats. For individuals who need to lose weight can limit consumption of dietary fat. Doing this eliminates excess calories but not nutrients.
