Here are some foods which help produce more brown fat.
Hot Peppers
Capsaicin is a compound found in hot peppers that stimulates brown fat, and can increase your energy expenditure and help you burn fat faster. You can sprinkle hot peppers onto your meals to get this brown fat-stimulating booster.
Green Tea
Green tea can also increase brown fat. It has caffeine, eigallocatechin-3-gallate, and catechin. All of which assist your body with burning fat and calories. Antioxidants in green tea decrease inflammation and prevent oxidative damage.
Turmeric (Curcumin)
Turmeric can increase brown fat and calorie expenditure. It’s important to be liberal with your turmeric intake though, as it can be hard to digest fully. You can add turmeric to soup, stews, curries, and marinades.
Menthol (Spearmint and Peppermint)
Metabolically active brown fat can be increased by the long-term use of menthol. This helps prevent weight gain and increases caloric expenditure. It can also reverse sensitivity to insulin.
Omega-3 Fatty Acids from Fish
Omega-3 fatty acids are great for weight loss. Whether you’re a fish fan or not, you can get them in supplement form. Consuming fatty fish can reduce your visceral fat and increase the production of brown fat.
