Nutrition,

Moving away from faddy, over complicated diets. Most diets in magazines and other places are complicating a very simple concept that is getting your body enough nutrients to survive, and live an active illness-free life. Calorie intake is based on the average person using 80 Calories every hour for normal daily functions, these include breathing and digestion. Also your body will not distinguish between different foods; once food has left your pallet you body only recognises SIX things, Proteins, Carbohydrates, Fats, Vitamins, Minerals and Water. (Fibre as a separate item as it has little or no nutritional value, it I though essential for the health of your digestive tract). You should be aiming to eat a varied balanced diet containing about 65-70% Carbohydrates, 20-25% Protein and 5-10% Fat as a good average, and drinking 2-3 litres of non-alcoholic fluid a day.
