Eating peanuts will make you fat, because peanuts are oil-rich crops. Generally, eating 15 to 16 peanuts is equivalent to a spoonful of oil, and a spoonful of oil is 10g oil. Therefore, if you eat peanuts in large quantities without restrictions, it is equivalent to drinking many spoonfuls of oil, which will cause obesity because of the high energy brought by oil.
Peanut texture is definitely good, which helps to keep cardiovascular patency and keep weight loss, but the amount of peanut oil is large. Peanut is a kind of good dried fruit, known as longevity fruit, but long life can't be at the expense of gaining weight.
