Unexpected weight gain

Another indicator of iodine shortage is unexpected weight gain. It might happen if the body does not have enough iodine to produce thyroid hormones. This is due to the fact that thyroid hormones assist regulate the rate at which your body transforms food into energy and heat.

When you have low thyroid hormone levels, your body burns fewer calories at rest. Unfortunately, this implies that more calories from your diet are deposited as fat. Increasing your iodine intake may help counteract the consequences of a sluggish metabolism by allowing your body to produce more thyroid hormones.
