What are the roles of diet in fitness and how health is related to diet.

A famous quote of all the time, "Healthy mind lives in a healthy body". The latest version of it "A healthy body is related to healthy diet". If you go to gym or you do any type of physical exercise, then main role is always played by diet. A healthy body is 30% workout 30% sleeping and 50% proper diet. A balanced diet provides all of the energy you need to keep active throughout the day and nutrients you need for growth and repair, helping you to stay strong and healthy and help to prevent diet-related illness. 

Keeping active and eating a healthy balanced diet can also help you to maintain a healthy weight. Deficiencies in some key nutrients - such as vitamin A, B, C and E, and zinc, iron and selenium - can weaken parts of your immune system. A healthy diet rich in fruits, vegetables, whole grains and low-fat dairy can help to reduce your risk of heart disease by maintaining blood pressure and cholesterol levels.

Eating a healthy diet that includes lots of fruit, vegetables, whole grains and a moderate amount of unsaturated fats, meat and dairy can help you maintain a steady weight. Having a good variety of these foods every day leaves less room for foods that are high in fat and sugar - a leading cause of weight gain.
