Eating. Yes, as I am a kick boxer  I must stick to a strict diet. I must have lots of greens for iron, vegetables to fill up on, meat and protein so that my muscles can form well. Not too many carbs, because they'll turn to fat; however, some are good to keep up your energy.

Sugar is a big 'No', and that is definite. 

Most people know that sugar is bad for those who work out, but they don't always know why. 

Here's why:

Once consumed, most sugary sweets turn into glucose. Yes, they do give you a sudden hit of energy, but if it's not burned off soon, it turns into fat for storage. When you work out and you've had sugar, the exercise first burns off the glucose in your body, and then the fat. But you'd want to burn the fat off straight away, right? So if you've had no sugar, then the fat burns off first, and you're doing exactly what you want. Then once the fat is burning off, the muscles start to get going and build. 

If you're wondering about what kind of meat to have, try to avoid sausages, fried meat, duck, pork, the fatty bits of meet and processed food. Also, when you have any food, try not to add too much salt, as that clogs up your arteries and blood. Fish is very, very good for you.
