If I consume 2400 calories before bed every night, will I gain weight, and if so, how quickly do you think I would...?

I maintain a 2000 calorie a day diet, but most of the time it's always less by 100-300 calories. But that's going to change soon anyways.

Also, my current height/weight is 5'3 and 131 lbs
