thats EXACTLY what i said a couple of posts back, so we can agree on that.
actually, muscles primarily use fatty acids at rest for energy. when exercise begins, muscle glycogen becomes the primary source of energy in muscles. as muscle glycogen is depleted, muscles then begin to use blood glucose for energy.
i assure you atkins did not invent ketones, and it is not babble.
under NORMAL conditions (normal carb intake), that is true. once the body stores of glucose are depleted and fat is being broken down to be used as an energy source, ketones can be used by the brain as a source of energy. perhaps this is physiology 201. do a web search using brain/ketones/energy and you will see that is correct.
earlier, you said:
i agree. a serious athlete that is not fat has no use for the atkins diet. the atkins diet is meant to loose fat. if your body fat % is reasonable, i dont see why you would want to be on atkins.
