Let's not forget that the body burns more energy to digest some foods more than it does with others. When you eat proteins you burn more energy than when you eat carbos
No, that is something you can safely forget because the difference in energy requirement when breaking down food is very little when you also account for the differences in energy gained
. I am not saying there isn't a difference, just that for all practical purposed is it of absolutely no relevance to the huge majority of dieters.
When eating cold food burns your body burns more energy than when eating warm one.
The difference is so small, when compared to the different energy content of different foods, that this is close to being a myth. So again, this is something we can easily forget.
Actually I didn't exercise at all when I lost my kilos. I started doing this later. Another plus of proteins is that it build muscles and losing weight by means of this diet doesn't mean that your skin will droop and look grey. Proteins are digested for a longer period than carbos, so you won't crave food as often as before.
Going from a carbohydrate rich diet to a protein rich diet is an efficient way of reducing the amount of biologically available energy in the diet. But it shouldn't be necessary for people who only eat less enough or exercise enough, e.g. to people who can't get the basics down.
