Diets. Several members of my family, like my wife and my father, have truly benefited from diets based on the Hay method. Not for slimming purposes (they don't need to) but for well-being and general good health. No question, the diets work for them.
However, being obsessive, I weigh myself daily, removing my watch and socks to ensure absolute accuracy. I am therefore looking always for scientifically sound methods of staying well, living longer, and losing weight. New research is always coming along, so this area ought to really easy to get the best info on. In fact, as you know, it's the reverse. There is probably no field of human interest that has so much hokum and deliberately misleading information about it. There are almost no independent summaries of latest scientific thinking, and every 'new diet' contains highly one-sided collections of news reports and badly interpreted research that purports to support their method.
I was prompted to investigate further after thinking about the Hay diet (and its' follow-ons, such as Fit for Life, the Atkins diet, and my own favorite, Dine out and Lose Weight). I wondered what the latest scientific view was of food combining, which is at the core of all these diets. As a result of searching, I found the following resources/links. You might find them interesting. Like may of the other sections in Good Stuff, I'll expand more later, and tell you why the Montignac Method (as described in 'Dine Out and Lose Weight') is such fun (and the father of all Glycaemic index diets).
