I like Colpo despite the fact that he can be abrasive and has had at least one go around with just about everyone in the diet, fitness, and cholesterol world. Richard Nikoley, Martin Berkhan, Fred Hahn and Durrian (not saying that he's not a douche bag that tangles with everyone himself) have also all had inflammatory exchanges with him as well.
Colpo himself doesn't really advocate for sugar use, he just doesn't think that carbohydrates should be demonized and that exercise is an important part of staying healthy. He also thinks that if you're going to be giving out health and dietary advice you should be fit yourself. I agree with him on that. Guys like Lustig and Taubes would be better served to get into top shape themselves before they go advocating for their causes.
