Drinking enough water is a great way to stay hydrated. Additionally, some studies show that drinking water may also briefly boost metabolism by 24–30% (36Trusted Source, 37Trusted Source, 38Trusted Source).
Researchers note that about 40% of that increase is explained by the additional calories needed to heat the water to body temperature — known as water-induced thermogenesis.
However, the effects only appear to last for 40–90 minutes after drinking water, and the strength of the effect may vary from person to person.
12. Seaweed
Seaweed is rich in iodine, a mineral required for the production of thyroid hormones and the proper functioning of your thyroid gland (39 Trusted Source).
Thyroid hormones have various functions, one of which is to regulate your metabolic rate (6Trusted Source).
Regularly consuming seaweed can help you meet your iodine needs and maintain your metabolic health.
Furthermore, fucoxanthin is another seaweed-based compound — primarily found in brown seaweeds — that may increase your metabolic rate (40).
