Unexpected Weight Gain
An unexpected increase in weight can be a sign of inadequate iodine levels, as iodine is vital for synthesizing thyroid hormones that regulate metabolism. A deficiency in these hormones slows down the metabolic rate, leading to the body storing more calories from food as fat rather than converting them into energy. Increasing iodine intake can aid in reversing the effects of a slowed metabolism by facilitating the production of thyroid hormones.
Feeling Colder Than Usual
A notable sensitivity to cold may indicate an iodine deficiency, as more than 80% of people with low thyroid hormone levels report feeling colder than is typical for them. Thyroid hormones play a crucial role in regulating metabolism and body heat production. A deficiency in these hormones can lead to a decreased metabolic rate and reduced heat generation, making one feel unusually cold. [4]
