I agree that fructose (when eaten separately without the surrounding real fruit) is bad. But people should go some steps further: The whole composition of stuff most people eat is wrong (low fat, high carb). I recommend having a look at paleo-style diets (e.g. http://www.gnolls.org/1141/ http://www.gnolls.org/1141/ ) which mean high fat, mid protein, low carb. They provide more satiety, no after-lunch tiredness and a lot more. My own way was going from no fructose (thanks to Lustig's video) to now cutting grains too. Feels good. EDIT: And forget about counting calories or thinking that (eating fat == becoming fat). That's not how digestion works. Calories were afaik defined by burning (with an actual flame) the food. That's not how your organs, enymes, stomach, ..., bacteria work.
