I am totally confused by you now Sean. The post I have just replied too made it look as if you were discouraging eating starchy foods this one is far more sensible and advocating them as primary source.
I would go further on the starch food in a way, because staple foods, potato etc. is starchy, as are most vegetables.
The carbs are fattening myth annoys me severely. Sugar messes with the insulin curve, but starch doesn't, both can be burned as energy before being committed to store, the body would rather burn it, next priority is store it using glycogen, only when these stores are full will the excess be converted to fat. Protein in excess, if absorbed, will be converted to lipoproteins (the lipo bit means fat) or excreted out of the body so high protein fanss will continue to wonder why those last pounds aren't dissappearing. Fat doesn't need converting because, hey it's already fat. And there are still so many labelling carbs as the bad guy.
As you said carbs are 4 calories per gram, same as protein, fat is 9 so over double.
The final nail in the coffin for low carb diets is metabolism. The body uses various methods to assess the ideal metabolism, activity, general health etc. but a few are dietary and the most major is assessing the amount of carbs coming into the body. We are designed for most of the calories to be from carbs so this makes total sense. So eating less carbs makes your boday assume you are in a lean time and it needs to conserve energy. In contrast eating more tell it you are in time of plenty and ironically it will be more willing to unlock fat stores because it is confident of getting the energy back.
You have confused me but that could easily be me misunderstanding, senility hits hard you know. Welcome to the boards.
