Weight Gain from High Chocolate Consumption: A Calorie Analysis

Question
My friend who is 51 years old eats 440 calories worth of chocolate every evening. She eats a total of 3000 calories weekly that comes from milk chocolate. She is physically active and is a vegan. Can you tell me how many pounds she might gain from eating chocolate at this rate?

Answer
Louise,
It totally depends on how active she is and the other calories she eats, but in theory it takes 3500 extra calories to gain a pound a week, so .85 of a pound a week is possible.  For some people they could gain more, or less, or not at all.  
I hope this helps,
Lea
