I think that these videos hit the nail on the head if the nail is HEART DISEASE, but the thread is about OBESITY. Nevertheless, both videos were interesting and worth watching. What I got out of the videos is that saturated fats and cholesterol are not the biggest contributors to heart disease, but that pharmaceutical companies have capitalized on misconceptions focusing in particular on cholesterol. (The theory linking cholesterol to heart disease was based on bad science, with researchers cherry-picking evidence to support their hypothesis.) As far as diet goes the Mediterranean Diet is associated with a reduction in heart disease. It is relatively low in sugar and relatively high in Omega-3 Fatty Acids, but not particularly low in fat in general. Sugar is a problem because it is associated with inflammation. The same goes for stress. The pathway with sugar has to do with an insulin reaction, whereas with stress it has to do with release of cortisol. (I don't think the video mention cortisol, btw.) Trans fats are yet another problem substance mentioned in the videos. Also important is to get at least two hours of moderate, continuous exercise every week. (By continuous, I mean exercise sessions lasting at least 20 minutes.) Is this what you got out of the videos, SurfSteve, or am I missing something?
