Low carb diets work, but when people eat things that are from commercial farms, pesticides, or processed meats from commercial farms,etc and expect to get healthy... well... they don't.
These things that are happening to the health of the world, and Americans in particular are from all of the coeporations wanting to get rich of of us, and putting processed junk packaged to sell in our stores. When WE as consumers begin to eat only those things that are healthy, and let the porcessed junk rot on the shelves... then we will be not only healthier, but there will not be as much need for those pharmeceutical drug pushers either.
