When you’re craving a midnight snack, peanut butter is a tempting choice due to its rich flavor, creamy texture, and sweet and salty taste.
Thanks to its impressive nutrient profile, some health advocates recommend eating peanut butter at night to support muscle growth, stabilize blood sugar levels, and improve sleep quality.
However, it also contains a lot of calories per serving, so you may wonder whether eating this filling food before bed leads to weight gain.
This article explains whether eating peanut butter before bed causes weight gain.
Therefore, it’s a great food for a healthy, balanced diet, but large amounts may increase your daily calorie intake. If you consume more calories than you burn throughout the day, you may gain weight in the long run (
Nonetheless, weight gain is based on many factors, including your age, size, activity level, health status, and overall calorie intake.

Peanut butter is high in heart-healthy fats and calories, meaning that eating too much before bed may lead to weight gain.
Research on the connection between eating late at night and weight gain has turned up mixed results.
Potential for weight gain
A few studies suggest that eating large amounts of food late at night impairs weight loss and raises body weight. However, other factors may also play a role, including your overall diet quality, sleep duration, and other habits, such as skipping breakfast (

If you’re trying to lose weight, consider lower calorie snacks like hummus, yogurt, hard-boiled eggs, or fresh fruit instead.
However, if you’re trying to gain weight, build muscle, boost metabolism, or improve sleep quality, snacking on a spoonful of peanut butter can be a good choice, as it supplies key nutrients like protein, vitamins, minerals, heart-healthy fats, and tryptophan.
