But, some people on blogs trying it and then some of them saying a diet works is not really scientific. What would be needed is a larger scientific study. You can argue that such a study should be funded.
In fact, there does appear to be some scientific research, based on some quick googling [1]. If your goal is to increase the adoption diets based on those studies, then I would cite them directly. Promoting that work might work better.
