OBESITY REVISITED
Two years ago I wrote three articles about obesity. In them I described the basic biochemistry facts of fat use and storage. It was a very simplified view, since I described the functions of only three hormones (insulin, adrenaline and glucagon) involved in energy metabolism. There are a few more whose functions are known and undoubtedly others that remain unknown, but for my purposes those three were and still are enough for you to understand the problem.,Two years ago I wrote three articles about obesity.
