Like other poster said, carnivore. 40% protein, 60% saturated fat. Keto {<25g carb) will shred the weight, but non-keto carnivore plus some honey and fruit will improve insulin sensitivity over Keto and will help you retain electrolytes.

Throw out the “protein” shakes and powders. Those are soy, pea, fiat garbage. The only protein you should be eating is meat.

Enough fat is the key. Fat will turn off the hunger and cravings in your brain. Eat enough fatty red meat (ribeye, 80/20 grnd beef) that you are not only full, but physically can’t eat any more. For me this is just under 1kg per day.

As far as intermittent fasting…with a high fat carnivore diet, you can eat 1 meal a day, even skip a day eating, and not feel hungry in the slightest. I go about 30 hours before I really start to feel hunger, and even then, it’s very gradual, I am still able to function normally.
