One anecdotal story does not make it true, DarlinLaurie. If you wish for an anecdote, I am full of energy always and I do not eat a low carb diet. I have been saying that different diets fit different training routines and that form follows function.
Carbs are the bodies primary source for energy, that statement is scientifically accurate and no amount of debate can make it false.
I have stated that processed flour and sugar is bad. I have stated that most every long distance runner carbo loads. Just because one was found, does not make my statement invalid.
I was a fat kid all through my life until I turned 16. The method I used to lose the weight was limiting my caloric intake and exercise. At the time I did not know about dietary specifics, I just did it with a good old calorie counter.
Carbs are converted to energy much easier then protein. Protein is an inefficent energy source is all I am saying. Fat is calorically dense and that is why eating to much of it might make you fat. It has twice the calories of protein and carbs.
Diabetes and all the problems associated with Americans are because of too much processed sugar and sedentary lifestyles. I guess I am one of the few "Bad guys" on this thread and damn it, its fun! ;)
