Take your weight, multiply it by 10 and then add 30%. That’s your base.

Less calories than that you burn. More you gain weight.

All it takes is a meal from Mickey D’s and that’s it for the day.

K. 120 x 10 x 1.3.

That's 1560 Kcals.

I eat more than that for first and second breakfast.

I don't gain weight.

Different people process food differently. There is no rule that works for everyone. (unless you are a gooberment employee)
