Here’s an interesting video about weight loss/gain. It’s definitely worth your time watching if you take this stuff seriously.

general idea of video: It’s not necessarily all about watching your calories as much as the type of carbohydrates you consume.
Personally, I also obsessively try to avoid artificial sweeteners like high-fructose corn syrup and aspartame.
