How Peanut Butter Can Support Healthy Weight Gain
Peanut butter can help people gain weight because it contains many calories in a small serving.
This can be useful for people who find it difficult to eat large meals.
It also provides mostly unsaturated fats and some protein.
However, peanut butter alone does not build muscle.
Building muscle also requires strength training and enough protein from foods such as eggs, dairy, fish, chicken, soy and pulses.
Peanut butter can be mixed with foods like oats, bread, bananas or smoothies.
Eating too much can add calories very quickly, so portions still matter.
People with unexplained weight loss or trouble gaining weight should talk with a healthcare professional.
Peanut butter provides roughly 180–200 calories and 7–8 grams of protein per two tablespoons.
Its predominantly unsaturated fats offer concentrated energy that can help create a calorie surplus.
Peanut butter can be added to toast, oatmeal, bananas, smoothies, yoghurt, milk and pancakes.
Muscle gain requires peanut butter to be combined with resistance training and adequate protein.
People should choose products carefully, control portions and seek medical advice for unexplained weight changes.
