Does Soy Milk Promote Weight Gain?
Contrary to popular belief, there is no scientific evidence to support the claim that soy milk causes weight gain. In fact, several studies have shown that soy milk may actually help with weight management.
1. High Protein Content
The high protein content in soy milk can promote satiety, which helps reduce calorie intake and supports weight loss. Protein takes longer to digest, leading to a sustained feeling of fullness.

The fiber in soy milk adds bulk to the diet, which can help slow down digestion and absorption of nutrients. This can contribute to a feeling of fullness and reduce overall calorie intake.
3. Low Calorie Content
Soy milk is relatively low in calories compared to other dairy and plant-based milks. A cup of unsweetened soy milk contains approximately 80 calories, while a cup of whole milk contains around 150 calories.

- A study published in the Journal of the American Dietetic Association found that overweight and obese women who consumed soy milk experienced significant weight loss.
- A meta-analysis of 11 studies concluded that soy protein consumption was associated with a small but significant reduction in body weight and body fat.
