Question: how much weight can you gain from a jar of peanut butter?
Answer: For most people, this means sticking to 1–2 tablespoons (16–32 grams) per day. Visually, 1 tablespoon (16 grams) is about the size of your thumb, while 2 (32 grams) is about the size of a golf ball. Opt for peanut butter that contains no added sugar and has a simple ingredient list, such as peanuts and salt.
