tl;dr: Stop eating sugar. Especially stop eating fructose. Don't obsess over the fat.

Body: Most of us understand this, and that's fine. This is for the fatties among us who don't understand why they keep staying fat.

Here is the video by the guy that explains it in gory detail. Dr. Lustig: https://www.youtube.com/watch?v=dBnniua6-oM

Quick summary of the video for the impatient:

  1. The government went on a crusade to get us to reduce our fat consumption, which we did. As a result, every single age and body type is more obese today than before.
  2. Every society that doesn't have an obesity epidemic avoids fructose and the "western diet."
  3. Every society that converts to the "western diet" gets an obesity epidemic.

It isn't in our genes. It's in our education. The fatties of the world are trying to eat healthy, trying to eat right, but the game is stacked against them. If they all learned what this guy is trying to teach them, they could stop being fat.

Lesson Learned: I should have a little bit of sympathy for fatties. I should give them a link to this video. If they reject its lesson, I should cut them out of my life.
