What exactly does it do to the diabetic?
Carbs are what cause insulin and blood sugar to spike. Keto is a high fat, moderate protein, extremely low carb diet. Some people think large amounts of protein will also spike insulin release and blood sugar, but that not everyone thinks it’s much of a problem.
If you don’t eat carbs, you don’t release a lot of insulin, so your blood sugar doesn’t go up. Many think the increase in circulating insulin is what really damages the body, more so than the increase in blood sugar.
People who go on a very low carb diet, usually lose weight and report less hunger. In spite of the high fat diet, triglycerides go down and HDL goes up. For some, LDL also increases, but I think cholesterol is a bogus risk factor, unless you are one of those plagued by a genetic condition that causes astronomical cholesterol levels.
Atkins was more of a high protein diet, but keto is high fat and moderate protein.
Seniors should read the book “Rethinking Aging: Growing Old and Living Well in an Overtreated Society” by Nortin Hadler, MD. He’s not a proponent of any particular diet, but he does shine a light on all the unnecessary tests and treating for numbers that happens today.
