Dr. Adkins was a cardiologist. Ivy League - Cornell Medical School and residency at Columbia.
All I know is, the diet I follow that limits sodium, carbs and fat has worked for me. Lost weight, improved cholesterol and diabetes numbers and has lowered blood pressure. The meds I take have been reduced and some of them I might one day not have to take anymore.
By the way, my cardiologist is highly regarded and respected by his peers too. But he also has enough sense to know that he, like most doctors, doesn't know everything about diet, so he referred me to a registered dietitian. The diet I follow came from that dietitian and it has worked for me. And I still consult with that dietitian once a year in case there are any new advances.
I got fat and wrecked my health through excess. Too much of anything — including fat — can damage your health. I'm not about to undo the progress I've made by following fad diets promoted by charlatans with MD after their names who only want to sell a book and a bunch of overpriced, totally useless products.
