excluding supplements I would say about about 300-400 a month. Physical job(warehouse) + naturally small skinny frame+heavy lifting in gym=huge amounts of food to maintain or increase current bodyweight
I burn between 3000 cals to 4000 cals somedays at work. So visits at tacobell or eating whole pizzas are a must some days on top of my clean eating.
I was in a competition with someone to see who could get the lowest weekly bill. I can’t seem to do it for under $80, with $100 being the general average. So, $400 a month.
I buy massive quantities of meat and freeze it. And I don’t buy organic or grass fed anything. Too poor, and really don’t see cost/benefit ratio being justified.
