Jason Fung is probably the world's leading research expert on obesity. If you want videos to watch on it, it starts and ends with this guy. He has done a ton of lectures and blogposts going back over a decade, and also has the stereotypical clickbaity YouTube videos. [VIDEO]

Minor point, but Dr. Jason Fung has a very interesting and, in my opinion, compelling explanation of obesity and weight gain. He argues that the main driver of obesity in the long term is insulin rather than total calories, and because alcohol doesn't significanlty raise insulin it doesn't contribute to obesity, despite the calories.

[VIDEO] i'm not sure if you're being serious but it'll take longer than 20 miutes, more like 6 hours. this isn't a simple topic but the new science on it is compelling.
