There are several diets out there- particularly Keto, that people have had a lot of success with. In just 2 months I almost lost 30 pounds (call it water weight all you want) and it was a low carb, high fat diet. My bad cholesterol even went down a couple points, and I still feel like I have my muscles. There is a lot of research supporting this idea out there, if you realize that the FDA is probably bought out by people who make high-carb, high-profit foods.
