With respect to T2 diabetes only, a great deal of money is spent establishing wrong/no dietary advice, making three million people ill and giving them tablets that don't do anything except giving quite a lot of people adverse side effects. Also, those three million people (UK) have foot checks, eye checks, blood tests, courses on how to avoid fat and while they are at it they are given blood pressure pills. The papers by Dr David Unwin are revealing. He and his wife took a group of patients, put them on low carb while he weaned them off of pills he didn't think they needed. He now has a group of lighter patients who feel well and he has saved a lot of money. I haven't got the exact figure but I think it's around £40,000 all because he uses fewer pills. If all of that was rolled out across the country we wouldn't have the impending disaster which is repeatedly forecast.
