I've recently started an(other) effort to lose my excess weight. Since this time I am on the web I have been looking for more research. It appears there is very little useful information available. The biggest problem, it appears to me, is the lack of any financial incentive to run large controlled trials of diets as there is in drug trials. What we really, really need for nutritional science to advance much more, is for large-scale controlled experiments, but without the millions of dollars drug companies put into testing their products, in the hopes of making it back from sales on successful drugs, it is not going to happen.
