You train to increase athletic ability, while you eat to change body composition.
Despite what most Dietitians and “Health Professionals” tell us, losing weight and staying healthy is not just about burning more calories than our bodies are taking in. Sure, if you constantly eat highly processed foods, but the calories you burn is always higher you may lose or maintain your current weight, but you are just constantly chasing your own tail. What if you become injured? Or you go on holidays? Or you become sick? Or you don’t keep up the amount of exercise you are doing as you get older? Or you over train? If your eating habits are poor it will eventually catch up with you and you will put on weight, or even worse suffer from lifestyle diseases such as Diabetes or Cardiovascular Disease. If your food intake is always healthy, then none of those situations will have much effect on your total weight.
Food is the fuel that runs your body and provides it with the proper nutrients it needs. You will be surprised how much a diet full of real unprocessed food will both increase your training results and change your body composition for the better.
If your current idea is to do extra exercise only so you can eat poorly, reassess your thought process. You train to increase your strength, fitness, posture, co-ordination, while you eat a diet full of lean meat, fish, vegetables, fruits,and good fats for body composition and weight management!
