Does Peanut Butter Make You Gain Weight? Expert Clarifies

People who are trying to lose weight often opt for peanut butter. However, they are often confused whether this spread is a friend or foe to their diet goals. While peanut butter is no doubt rich in calories and fats, if consumed mindfully, it may offer a powerful combination of protein and healthy fats. It can also keep you feeling full and satisfied. 

To set the record straight, Dt Gauri Soni, Head Dietitian at Fortis Hospital Ludhiana and Ms Chitra BK, Chief of Dietetics, KIMS Hospitals, Electronic City, Bengaluru clarifies whether peanut butter can lead to weight gain or not, as well as the best ways to add it into your daily diet.

Does Peanut Butter Make You Gain Weight? 

Let us begin by addressing the main point right away – can peanut butter lead to weight gain? Dt Soni says peanut butter can work for you or against you when it comes to weight loss; it really depends on how you eat it. 

The expert further explains, “On the plus side, peanut butter is a good mix of protein, healthy fats and micronutrients. I tell my patients to have it with something like bread or fruit, because its low glycemic index keeps you fuller for longer and stops that sugar spike. This  matters a lot if you have diabetes or PMOS, or you're just trying to manage your weight generally. The fats in it are mostly monounsaturated which support heart health. For vegetarians, it's a decent source of protein with around 7 to 8 grams in two tablespoons, in addition to magnesium and vitamin E.” 

Adding to this, Ms Chitra says, "Eating peanut butter alone doesn’t make you fat. You will be gaining weight if you are consuming more calories than the number your body burns. The reason for this is that the peanut butter is calorie dense, with around 90-100 calories per tablespoon. In addition to this, the product contains many essential nutrients including mono-unsaturated fats, vegetable proteins, fibres, vitamin E, magnesium and more."

How To Choose The Right Peanut Butter

Dt Soni says that here's where people go wrong — the store-bought ones are often loaded with hydrogenated oils and sugar. 

The expert explains, “If you're eating more than a tablespoon or two a day, those calories add up quicker than you'd think. Stick to something natural, homemade if you can, paired with fibre such as an apple slice at breakfast or as your evening snack, and watch it support your weight loss journey.”

Adding to this, Ms Chitra shares, "Consuming peanut butter in large amounts or opting for peanut butter that contains many additives such as sugar, salt, and hydrogenated oil will add up to the calorie count and diminish its nutritional value. The best option would be using natural peanut butter with as few ingredients as possible combined with whole-grain bread, fruits, or smoothies."

Do Peanut Butter Have Any Side Effects?

According to a 2022 study, published in the Foods journal, peanut butter has certain potential food safety hazards that may pose a significant public health risk. The research noted that the two major health threats associated with peanut butter are Salmonella bacteria and dangerous mold toxins known as aflatoxins. It noted that despite peanut butter's very low moisture content, Salmonella can survive inside it for remarkably long periods. Since peanut butter’s composition is a unique combination of high-fat and low-water, this acts as a shield, making it extremely hard to kill the bacteria. 

More studies have noted that peanut butter many commercially sold peanut butters have added sugar in them. Moreover, peanuts also have higher levels of Omega 6. According to a 2024 study, published in the Human Nutrition and Metabolism journal, a high intake of omega-6 may lead to an imbalance in the ratio of nutritious fatty acids and increase the risk of obesity and insulin resistance. Lastly, one tablespoon of peanut butter consists of around 95 calories, which may lead to weight gain if consumed in excess.
