Astrid, I see what you mean re the "low-fat" thing. I agree, most low fat packaged products contain way too much salt and sugar and are far worse for you in the long run.

I think my biggest beef with low carb diets is the effect it has on exercise. Glucose (a form of Carbs) is a major fuel source for the body and when too little carbs are consumed the body uses fat and protein to make energy. The problem is your body takes a lot longer to provide fuel from fat rather than glucose or glycogen so can really only be used when exercising at a low intensity. I think that the population as a whole should be undertaking more exercise and as such should be fueling their bodies appropriately but this is my personal opinion so please don't attack it!
Won't attack your opinion, it is just there is just so much myth out there about low carb, Atkins or some other style, that I like to show that is is not just about eating mounds of bacon. Low carb with exercise is something to be careful of, but then so is any eating with exercise. I have know of people who go to the extreme of exercising whilst only drinking juice for breakfast and eating fruit salads for lunch. I suppose it is all about balance and what is best for each individual.
