I've been doing a lot of reading lately on health. I came across this article. Dr. Dwight Lundell, a heart surgeon for over 25 years and 5,000 surgeries under his belt, makes a definitive statement that heart disease is caused by inflammation in the artery walls, not by elevated blood cholesterol. And the inflammation is caused by the low-fat, high carbohydrate diet recommended to us by the medical profession and USDA for the last decades, and the overuse of Omega-6 oils.
I've been low-carb for 6 months (fat is the predominant calories, followed by protein), and my body fat is much lower, my weight lower, and my cholesterol also better. I don't suffer from "low" blood sugar sensations, and my muscular recovery from hard exercise is also mild.
