I think you guys might be talking past each other. from what I seen the fundamental problem is many overweight people don't get the key for weight loss is to decrease the calories in and increase the calories spent. I had a couple of co-workers do the various Akins and Keto diets and still couldn't lose weight. Having them add up their calories, they were still eating 2000+ a day and walking a mile for their exercise. Trading bread for bacon only can do so much.
