Athletes must acquire the perfect combination of calories that can be consumed from protein, carbohydrates and fats, which are great sources of energy. Carbohydrates are the most important fuel source, which can be found in foods such as breads, pastas, rice, fruits, veggies and cereals. These foods can supply the body about seventy percent of the needed daily calories. It is difficult to assess free radical damage in athletes and it has been found out that large amounts of antioxidant nutrients may actually cause cellular damage and impair performance. The Carbo loading technique has been widely used over the years by athletes all over the world. A carbohydrate-rich diet is important in maintaining muscle glycogen stores thus ensuring high endurance levels. You, assuming that you are an athlete or thinking of becoming one, must, first and foremost, understand the principles of sports nutrition completely. What is the point of staying healthy when you do not even know what being healthy is all about? You must also avoid engaging yourself in false beliefs and misconceptions. But bear in mind that protein, is not only a source of energy, but exactly gives your body the power build new muscle tissues. Also during exercise, the entire array of your body s healing power is summoned. This dynamic of the human body is lost to many, specifically for those who do not believe on the necessity of involving into sports, or even simple physical activity. If you are losing fat quickly by starving yourself, over dieting and doing too much exercise, you may be at a risk of slowing down your metabolism and your body might start using the glucose found in your muscles as a source for energy. That is why losing weight bit by bit for a long period of time instead of losing weight quickly is much more preferable. Another is the Creatine, which is also for sports nutrition and muscle growth but it also involves bodybuilding this time; HCA or Garcinia Cambogia, for losing weight and suppressing your appetite; and last but certainly not the least, Vitamin B-12, this one is for overall health and nutrition.
