Soybeans have the capablility of getting converted into different foods and is often used instead of meat. As you are aware soybeans are rich in protein, they also contain a variety of beneficial compounds such as isoflavones. Isoflavones are antioxidants that have a structure similar to the hormone estrogen found in humans.

Health and nutrition circles have raised one concern about consuming soy products and that is whether it can lead to unintended weight gain by affecting the functioning of the thyroid gland. The thyroid controls the body’s metabolism and anything that makes your thyroid underactive can slow down the body’s metabolism, resulting in weight gain. Several studies have measured the effects of soy on the function of the thyroid gland. In one review published in 2006, all the studies were examined and it was found that there was no significant effect on the function of the thyroid gland. This suggests that soy is not different from other proteins when we talk of its ability to cause weight gain.

Points to be noted

Soybeans are no different from other foods when you talk of its ability to cause weight gain. If you want to add protein to your diet in order to increase your muscle mass, soy will help in increasing your protein intake. On a different note, soy does not seem to be more likely to cause weight gain when compared to other food of similar calories.
