How many calories do you eat per day on average?

For me it's 3500 normally
.
And about 6000 to 9000 when an ganing

I don't know. To be honest not looking to gain.

But anything over your Basal metabolic rate will lead to weight gain. There is calculators online to get a rough approximate.

Rule of thumb apparently is 3500 cal over bmr is 1lb gained. Do with that what you will.

Not a doctor might be worth doing your own research. Try to stay heathy-ish
