> Do not give yourself diabetes by eating vast amounts of sugar.
This can help sustain a high level of exercise (the more the better). Certainly don't if you're sedentary, but the sugar during exercise is really helpful for getting in 10+ hours/week of exercise.
I think the recent stance (not really recent in terms of assumptive idea, but now there is evidence) is that not all forms of sugar intake are equal. For instance, habitually drinking beverages with sugar in them (what are called sugar-sweetened-beverages in literature) is associated with a risk of developing T2D, where getting sugar from normal foods isn't really.
