I've made a big point of not paying attention to the world of diets, and so I am rather horrified by what I find now that I have to pay attention. There are not only so many conflicting and extremist approaches but so many conflicting goals. At the moment I'm trying to follow the goals explained here. I can do that and eat not too low carb a diet. But would it be better to eat fewer carbohydrates and have still lower blood sugar? Some people definitely think so, but at the moment I incline against the idea. The glycemic index approach allows selecting carbohydrates that have somewhat lower effect, but I don't find that much difference.
