Does eating peanuts cause weight gain?

Under normal circumstances, moderate consumption of peanuts will not lead to weight gain, but excessive intake may cause an increase in body weight. Peanuts are rich in protein, unsaturated fatty acids, vitamin E, B vitamins, and minerals such as calcium, iron, and zinc. Eating peanuts in moderation can provide energy and essential nutrients, help increase satiety, and assist in controlling total calorie intake. The unsaturated fatty acids in peanuts can help accelerate fat breakdown and metabolism, which may aid individuals in achieving healthy weight loss goals.

However, peanuts are relatively high in calories and fat content. Excessive consumption may lead to excessive calorie intake and consequently result in weight gain. Eating large amounts of peanuts may also cause digestive problems, such as bloating and abdominal pain. It is recommended that individuals with normal weight consume no more than 10 peanuts per day, while overweight or obese individuals should limit intake to 2–3 times per week, with no more than 15 peanuts each time. High-calorie processed peanut products such as fried peanuts should be avoided, and healthier options such as boiled or roasted peanuts are preferred.
