I think that people forget that all vegetables, all fruit and all dairy have carbs (even some meat cuts and organ meat have carbs) and somehow believe that carbs equals starches in grains and potatoes. You can feel perfectly well on low carbs if that is what your body demands. I would be in constant food coma if I tried to eat 50% of my calories in carbs, and would be seriously sick if I tried to get all these calories from grains. Again everybody is different and some people are not doing very well on very low carb diets, but I can bet that you will find more people who feel better and lose more weight on low carb diets than on diets high in corn, grains and potatoes.
