FAQ: Will Eating Peanut Butter Make Me Fat?

Q: Does eating peanut butter cause weight gain?

A: No. Fats used to have a bad rep because high fat foods have a lot of calories. Thankfully, we now know that fat is actually really important and not something to be avoided. That said, if you are trying to lose weight, it’s not a good idea to eat peanut butter all day long, since the calories will add up more quickly than they do for other foods.
