Well, he was on IVs and bed ridden (for a couple weeks) on top of what you mentioned. I personally think that eventually low carb will be accepted as beneficial by the medical community. And not just token concessions like the recent one by the ADA (who still recommend at least a whopping 120 grams of carbs for people with diabetes who want to lose weight with "low carb" and only recommend the diet for 12 months). Problem is, people really need to understand what it is that makes it work. Just eating low carb products or drinking soda as your carb for the day isn't going to give you much benefit.
It drives me nuts when people call it a fad diet. It's not a fad diet. The very first published diet was low carb (people can google "A letter on corpulence" if interested). It was published in the 1800s. It was devalued by the medical community at the time because Banting wasn't a doctor, but it was tremendously popular. Until calories became public knowledge, dieting was known as "Banting".
The idea that starches make you thinner is counter-intuitive to what we knew about reducing weight before the low fat diet became popular. I don't think that there's any coincidence in the fact we have gotten fatter and fatter the longer we are pushed to eat lower fat (with sugar usually replacing fat in dairy and processed food) and grains and pasta. Yeah, there's tons of sugar laden food out there, but not everyone's getting fat just eating that. If you have problems with insulin in your system, a glass of grape juice is probably going to do the same thing to your insulin levels (and how your body stores fat let alone cravings and diseases like yeast problems, pcod, heart disease, etc) as a glass of Coke.
Just a little upset by the little health advisory on all the packets of food yesterday. They listed calories, fat, saturated fat, but no mention of carbs. You had to look at the wonky table based on 100 grams or 100 ml thing. I think moving more towards an American system of listing the numbers per serving is great. Leaving out carbs is a huge mistake.
