I have tried, but Dukan needs to eat oat bran to lose weight, and he has to eat it all his life, which is particularly troublesome. And ask to eat less salt, that's all. Without salt, many meat dishes can't be eaten at all, which is no different from being hungry and thin.

I later transferred to McGee Plus, which looks similar to Dukan, but the principle of losing weight is (ketogenesis+gluconeogenesis), which is easier to adhere to and has clear theoretical support. I won't give you a prescription to do this, and I won't tell you the reason behind it.
