As I listened to this presentation, I was surrounded by the same group of people I remember seeing at Atkins events years ago (I used to attend for insight into that trend). Overweight people who are being misled by other overweight people who have good intentions but, need to open their minds and understand more than weight management and observational science, and the nutrient poor model of nutrition.
When weight gain is short term, all other lifestyle factors aside; it's not just the food, it is the affect of the food that really makes the difference.
This moderation in everything nutritional approach has been a disaster. It's not even a nutritional principle, it's an economic one. - John Allen Mollenhauer
This is a big question and it’s been on the minds of people for decades, particularly the last 50 years. This question raises countless more questions about health, whether you’ll get enough protein, calcium etc, and less importantly, but no less urgent for most people, it raises questions around weight.
