If you suffer from obesity due to a thyroid disorder, then using sea kelp can reduce the iodine deficiency, regulate metabolism rate and promote weight loss.

Since sea kelp contains good nutrients, consuming this can balance out the deficiency found in modern diets, improve digestion and fluid balance, leading to weight loss.   However, sea kelp supplements do contain varying quantities of iodine and caution must be exercised by those who consume this, especially if they have thyroid disorders.

Women who consumed plenty of calcium had less body fat and gained less weight.   Kelp contains 168mg calcium for every ¼ oz serving and also plenty of fiber, both of which promote weight loss.

Dietary fiber helps to relieve constipation and improve digestion. Kelp contains trace elements that maintain optimum balance of electrolytes in the body. When we exercise, we lose water due to excessive sweating.

At this time, electrolytes also get depleted from our system. Sea kelp which is rich in iodine helps to maintain electrolyte levels and normal metabolism, therefore promoting weight loss.

Low carbohydrate diets which are popularly recommended for weight loss programs can cause severe constipation and loss of calcium. Kelp contains calcium and acts as a natural laxative. It can therefore be used as a complementary diet to low carb diets.

How to make use of kelp to lose weight

Apart from those with thyroid problems, kelp can benefit anyone who wants to lose weight by adding it to various foods. For example, powdered kelp can be added to vegetables, salads, soups and baked dishes.

Kelp supplements can help digestion by promoting efficient burning of fat. A daily dose of 200-600mg kelp can be taken in three equal doses each day along with a glass of water.

Asian foods use seaweeds a lot and these foods are usually steamed or baked rather than deep fried. Deep fried foods contain unhealthy fats that promote weight gain. Liquid kelp is also available and this can be added to tea or smoothies.


Sea kelp can be used only for 2 weeks at a time.

Always take a break and start again. This avoids an overdose of iodine which can cause serious imbalances in functioning of the thyroid. Since most of seas and oceans are polluted, it is important to know where sea kelp is coming from.

Oceans surrounding Iceland, Hawaii, North West United States and Canada are relatively pristine and pollution free, hence choose kelp which is harvested in these seas.

Those with thyroid disorders must be careful, for excess kelp can worsen their conditions. In fact prolonged usage without a break can lead to greater risk of thyroid cancer and goiter.

Kelp harvested from heavily toxic areas will contain arsenic and other poisons.

Pregnant women and those who are breastfeeding, those who suffer from iodine allergies or women who are infertile must avoid kelp. Do not take kelp 2 weeks before any surgery for it could slow blood clotting and cause excessive bleeding after surgery.

Check with your doctor if any medication you are taking could interact adversely with kelp.

Follow all relevant dosages mentioned on the label to make sure you take the appropriate dosage for your age and health condition. Check with your doctor before starting any weight loss program.
