Though there is little evidence that directly supports kelp's weight loss benefits, it contains numerous vitamins, minerals, fatty acids and amino acids, in addition to iodine, that could benefit weight loss.
Kelp has the potential to reduce iodine deficiency and help regulate an individual's metabolic rate in cases where individuals are suffering from a thyroid disorder. Because it contains many beneficial nutrients, kelp may treat vitamin deficiencies caused by modern diets, resulting in improved digestion, fluid balance, and possible weight loss.
Kelp is a good source of calcium with 168 milligrams for every 1/4 ounce serving. In addition, kelp contains fiber, which aids in weight loss through improved digestion. Sea kelp consists of elements that help with electrolyte imbalance in the body, which is caused from excessive sweating and water loss. The presence of iodine in kelp also helps regulate electrolyte levels and normalize metabolism.
Kelp supplements can help digestion by supporting the burning of fat. It is recommended that kelp be taken for a maximum duration of two weeks to avoid iodine poisoning, which is known to cause imbalances in thyroid function. In addition, prolonged usage of kelp increases the chance of thyroid cancer and goiter, especially for individuals who already have a thyroid disease.
