Not mental… but bodily health.
If you are 5% body fat, like me, with a six pack, sleeping 8 to 12 hours a night, lifting weights every day, spending all day outside in the beautiful sunlight… Lifting weights, intermittent fasting all day… Certainly you will have no mental health issues. Also, no smoking, no weed, no cigarettes, no alcohol… Only 100% carnivore diet, at night.
Eat beef ribs, cure your problems.
