I have had several readers contact me about switching from a Keto diet to the Mediterranean diet. Let me start by saying that any diet for weight loss will have results if you follow it. Studies have shown that optimizing adherence is the most important factor for weight loss success. Having said that, when choosing a diet, an eating plan, a way of life- you really need to think about how realistic it is. Can you eat this way forever and be content? If the answer is no, then most likely that diet will be a failure.
