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.
