"The Battle of the Diets"

This video is an hour and 30 minutes long.  Because there are a few instances where he mentions copyrighted materials in his slides, those are blacked out while he has his discussion.

Christopher Gardner led a study on weight loss comparing different diets, from high fat/low carb to low fat/high carb.  And the results were interesting, to say the least.

If you want, skip ahead to the end where he talks about people's ability to lose weight on low carb vs. low fat.  I won't spoil it for you, but even though I was already diagnosed with the diabetes at the time I watched this, it kind of cemented my reasons for going low carb.
