You can't lose weight by starving yourself. It's a disease from a lack of cobalt. Cobalt is crucial in mechanisms that tell the body how much oxygen you need. If cobalt isn't present, its place is likely taken by zinc, which is different and so the point is set incorectly. Zinc willingly replaces cobalt in proteins, and in most cases the enzyme works, but not exactly the same. For example, the antiferromagnetic bond between cobalt and copper in superoxide dismutase cannot form with zinc. Carboxypeptidase is much less active with zinc. etc. Either the mechanisms that tell your body it has enough fat are also affected, or, which happens regardless, your brown fat atrophies as it isn't supplied with enough oxygen and it's the amount of BROWN FAT that dictates how hungry you feel.

Avoid zinc and take cobalt

>You only need to follow strict paleo diet, workout two hours a day and take curcumin, ashwaganda, protein powder three times a day and crushed whale penis to get lean.

Nobody actually followed such a diet and those supplements are virtually all scam. BTW, have you actually seen real hunter gatherers? They are super tiny.

>you can't starve before you burn all fat.

False. You can and do starve before you burn fat. The body will burn some fat but your metabolism drops so low that you will regain more than you gained. You will be hungry, cold and weak and eventually get tired of that and regain.

>You can get cobalt from eating steaks

You can get tiny amounts of B12, but you need free/ other forms of cobalt in much bigger amounts. Even if it worked, there is no reason for supplementing cobalt through cow.
