Much of the "increased energy levels" that people report from excluding gluten probably has to do with the fact that gluten elimination diets often end up having a lower glycemic index. Most gluten sources are high in carbohydrates, specifically processed carbohydrates. Eating lots of processed carbohydrates spikes your blood sugar giving you short-term energy, but makes you tired once the sugar is removed from your blood stream. Gluten free diets often end up being higher in raw foods simply out of convenience, since most of the gluten free food items you can buy at the store are things like nuts, vegetables and the like. While gluten free dieting may be a fad that is annoying to your friends, the end result is that the majority of food people avoid is stuff they probably shouldn't eat that much of in the first place.
