I think most people know..

Generally we all know what is good and what is bad for us to eat. OK there is occassionaly an article that can question our beliefs but a bit of common sense can usualy hurdle that obstacle. Generally

1) Substances that artificially increases your energy levels will cause problems in the long run. If you are tired and need to rest then accept that it is your bodies way of getting you to stop. Yuppy flu or ME highlights the perils of ignoring these symptons.

2) Eat everything in moderation. Variety is key to peak performance.

3) Listen to your bodies needs. If you listen carefully it will tell you what it wants. Many weight problems are caused by not listening properly and allowing the heart to rule the facts. If you want some chocolate ask yourself why you need it. If it is for emotional support then that is comfort eating and is not needed for any reason other than to make yourself emotionally feel better. Learning to understand these impulses has far more long term benefits than dieting.
