Diet Comparison

Keto, carnivore, low-carb, Mediterranean: every diet has people swearing it's the one that finally worked. Most of them do work for weight loss, and mostly for the same reason. They help some people eat less without feeling miserable. The real difference is which one you can stick with. These head-to-head comparisons look at how two diets differ in what you eat, how restrictive they feel day to day, what the research says about results, and who each one tends to suit. Read them before you commit to a plan, not after you've already given up on one.
