Does kelp help with weight loss?

Kelp is rich in iodine, so it can help reduce weight in people suffering from obesity due to a thyroid disorder because it reduces iodine deficiency and regulates metabolism, according to The Superfoods. Kelp can also improve digestion and fluid balance, which promotes weight loss.

As of 2015, there is very little research supporting claims about kelp's general weight loss benefits, notes The Superfoods, however kelp can be used to supplement other weight loss methods such as eating a low-carb diet and exercising. The body loses electrolytes during exercise, and kelp's high iodine content helps maintain electrolyte levels. Low-carb diets often lead to calcium loss and constipation, and kelp contains calcium and acts as a natural laxative.
