Is there a calories per day formula for male weight gain?

Question

I need to gain about 7 pounds in two weeks for a walk-on film part in an indie-short film. How many calories do I need to increase my daily intake by to achieve this?

Answer 1

As a rough figure, 3.500 calories is equal to one pound. So you will need to gain about .5 pounds per day.  So to gain 1/2 per day, you will need to consume about 1,750 calories per day BEYOND what you would normally burn. I hope this helps.
