Calorie for Calorie, Dietary Fat Restriction Results in More Body Fat Loss than Carbohydrate Restriction in People with Obesity

This is a fascinating interview with one of the top metabolic researchers who has just come out with a groundbreaking new study.

Dr. Hall is famous for this article; a meticulously performed study where he kept people in a hospital ward and used state of the art scientific investigations to analyze their body composition and metabolism. He placed them on a very controlled diet, either low fat or low carb. Contrary to what he expected, and contrary to much of the common dietary advice, the low fat group lost more fat than the low carb group.

This study was criticized for not being long enough. In other words, the dogma is that the body must adapt to a high fat diet in order to start burning fat. SO Dr. Hall aimed to do a 2 month study. How he got people to stay on a hospital ward for 2 months is beyond me.

Interestingly, part of his funding came from an organization run by Gary Taubes. The organization specifically aims to prove the benefit of ketosis in diets. Well, after a very well controlled study, the ketosis did NOT increase fat loss, and there was an increase of protein lost.

These 2 studies really do seriously harm the common notion that it is carbs and insulin that cause obesity.

I really would watch this video by Yoni Freedoff to listen to an intelligent discussion of the science.
