I watched this video from a vegan doctor who claims that obesity in US stems from a low fiber high fat diet, abundance of processed foods that are high in calories.
Here is a movie "Forks over Knives" that he endorses:
I know he is wrong about being a vegan, but I am not so sure if he is wrong about eating high-fiber foods first. Somehow his logic seems off/skewed. But I cannot pinpoint exactly where he goes wrong.
The videos are a bit lengthy, but I am really interested in hearing your response to his high-fiber vs processed foods claim if you are willing to listen to it.
