Lack of appetite
I'm not sure if this is really a problem per se but I don't get hungry enough to eat very much. I have coffee with salted butter, octane oil and collagen first thing (with a Thorne Research multivit) Then I work for 12 hours and when I get home I'm barely hungry enough to finish one meal.
Just to clarify I eat one actual meal per day. A portion of meat and some vegetables (all green on the bulletproof sheet) cooked in ghee and soaked in melted butter.
On paper this is half the recommended amount of protein per day. I'm a 75kg 27 year old male. The recommended amount of protein per day is 60g for my body weight and I'm having 30g.
