How to stop feeling tired all the time:

• ramp up to at least 25g of fiber. frozen berries & psyllium husk are the cheapest sources afaik, & convenient smoothie ingredients

• track thermogenesis in foods. complex carbs & proteins lose up to 30% of their calories digesting. you want high thermogenesis but not so much you burden yourself

• get at least 1/3 of your calories from protein after the deduction I just mentioned above

• get a lot of potassium and magnesium. They are not found in vitamins. Magnesium oxide does not actually do anything

• drink plenty of water & don’t have caffeine after noon.

• stop vaping. Stop it. It fills your pleural cavity etc in your lungs with white blood cell goop
