Metabolic health appears to be directly linked to both body health and mental health

Eating local whole foods, nothing from a factory or a box or a bag - is a great way to remove a bunch of junk from your diet.

Check out your tg/hdl ratio on your last lipid panel, if its less then 2 its a good indicator your metabolic health is doing well, if its less then 1 then your metabolic health is doing great. If you have room for improvement then you could consider doing whole food low carb diet, as carbohydrates are heavily implicated in many instances of impaired metabolism.

Incorporate exercise and movement into every aspect of your day, don't stay indoors, get sunlight as much as you can, don't sit to long in one position at the office, etc. Exercise snacks, even as simple as taking the stairs, helps.
