When i initially started this thread i was originally going to dive straight in at the deep end and explain the importance of carbohydrates, protein and fat. In the end i decided to give my best explanation of how the body's energy system works. This hopefully will give you a better understanding of why nutrients are important.

So now i think i have pretty much covered everything i wanted to go through so i'll move on to talk about carbohydrates. I get a feeling this chapter is going to be quite long so i'll try complete it in stages...

to be continued......
