Topic: Hypothalamus

UVB light exposure to the eyes and skin triggers the production of Pro-opiomelanocortin (POMC) in the hypothalamus. While blue light can stimulate POMC in the pituitary gland to produce cortisol (ACTH), only UVB light unlocks the full repertoire of ten cleavage products. Chronic blue light exposure without UV balance leads to extended cortisol levels, which can promote catabolic tissue breakdown and systemic insulin resistance.

The discussion shifts to Monosodium Glutamate (MSG) and its role in the modern obesity epidemic. Dr. Blaylock cites neuroscientist John Olney’s research, which demonstrated that MSG destroys the part of the hypothalamus responsible for weight control in mice. This damage makes it biologically difficult for children exposed to MSG to lose weight, as the chemical also triggers high levels of free radicals in the liver.
