Might not be explaining very well here. Not like me at all....
I realise that you could lower your carbs dramatically without increasing your fat intake.
However a flick through the recipes in this GI Diet book seemed to have a lot of what to me looked like pretty unhealthy meals due to them being very high in fat.
The whole point is that the fat becomes the first port of call fo renergy consumption and therefore is never stored. Most of the fats tend to be simple fats to (ie not transfats)
From what I understand the body burns protein first because it can't store that?
That's why you have to take a protein shake after training because you've got none left and need to feed the muscles if you want them to grow.
The protein doesn't take long to burn though so it's gone pretty quick.
After that it's simple carbs (sugars, glycogen, red bull, energy drinks), complex carbs (potatoes, oats) then fat.
If you have no carbs in your body you will burn fat. Simple.
If you have eaten loads of fat you will burn that. If you haven't eaten loads of fat you will burn fat that is stored.
So basically if you go for a high protein, low carb, low fat diet (in percentage terms) you will lose weight.
If you aim for a 45/35/20 ratio for a total of 2200 calories and combine that with training you can't fail to lose weight.
