Omega-3 fatty acids are able to stimulate the activation of brown and beige adipose tissues, a discovery that would promote the development of new therapies for obesity and other metabolism diseases, according to a research study.
In inguinal WAT (iWAT), fish oil has been reported to increase expression of several browning marker genes such as Ucp1, Prdm16, Tbx1, Pgc-1α, Cidea, Adrb3, Cd137, and Cpt-1β [8,11].
Exposing your body to cool and even cold temperatures may help recruit more brown fat cells. Some research suggests that just 2 hours of exposure each day to temperatures around 66°F (19°C) may be enough to turn recruitable fat brown. You may consider taking a cold shower or ice bath.
Increasing exercise and physical activity may help to increase a protein called irisin, which may be able to convert white fat to brown fat, says Prest. “Leaner people tend to have more brown fat than those who are sedentary.”
The omega-3 fatty acids in fish oil have various potential health benefits, one of which is aiding weight loss. More importantly, fish oil omega-3s may help you lose inches and shed body fat. However, studies have found these effects appear to be modest, and they may not apply to everyone.
Fish oil helps build muscle mass in the body and burns extra fat. Regular consumption of fish oil per dosage can help you lose weight and burn belly fat.
Resveratrol, a polyphenol compound found in red wine, cabbage, berries and spinach initiated fat browning in tissue cultures and also in live mice. Capsaicin, the spicy component in hot peppers, activated brown fat in rodents and humans in other studies. Curcumin, a component of turmeric, induced fat browning in mice.
Scientists have discovered that exposure to cold conditions is a way to activate brown fat. It was shown in a study that brown adipose was activated after subjects were exposed during 10 consecutive days in mild-cold conditions (15-16 degrees).

However, how to safely increase brown fat tissue has eluded researchers, until now. In a study published by Scientific Reports , scientists report their success with a method to directly convert white fat to brown fat outside the body and then return it to the patient as a transplant.
There's strong evidence that omega-3 fatty acids can significantly reduce blood triglyceride levels. There also appears to be a slight improvement in high-density lipoprotein (HDL, or "good") cholesterol, although an increase in levels of low-density lipoprotein (LDL, or "bad") cholesterol also was observed.
They also bind to receptors in cells that regulate genetic function. Likely due to these effects, omega-3 fats have been shown to help prevent heart disease and stroke, may help control lupus, eczema, and rheumatoid arthritis, and may play protective roles in cancer and other conditions.
Although recommendations can vary widely, most health organizations recommend an intake of at least 250–500 milligrams of combined EPA and DHA, the two essential forms of omega-3 fatty acids, per day ( 24 , 25 , 26 ).
A high omega-6 fatty acid intake and a high omega-6/omega-3 ratio are associated with weight gain in both animal and human studies, whereas a high omega-3 fatty acid intake decreases the risk for weight gain.
Aging skin may also benefit from omega-3 supplementation. Sagging skin results from loss of elasticity and unfortunately is inevitable with aging. The combination of EPA and DHA (from fish oil) and GLA (from evening primrose oil) has been shown to increase skin elasticity (Segger et al., 2008).
In general, omega-3 helps to reduce risks of heart diseases and cancer. However, women benefit more as omega-3 protects against certain conditions that affect only women such as menstrual pain, osteoporosis and rheumatoid arthritis.
It is well understood that omega-3 fats play a key role in boosting heart health, but evidence has also found them to be a potent weapon against visceral fat. Studies in adults and children with fatty liver disease show that fish oil supplements can significantly reduce liver and abdominal fat.
How long does it take for omega-3's to work? Levels of omega-3's build up quickly in the body once you take supplements. But it may take 6 weeks to 6 months to see a significant change in mood, pain, or other symptoms.
Summary. Some evidence suggests that taking supplements that contain omega-3 with a meal that contains fat can increase absorption. As a result, people may wish to take fish oil at breakfast, lunch, or dinner. However, there is no correct or incorrect time to take it.
For adults with high cholesterol levels: The AHA recommends an omega-3 fatty acid supplement (as fish oils), 2 to 4 grams daily of EPA and DHA. It may take 2 to 3 weeks to experience benefits from fish oil supplements. Supplements should be taken under the direction of a physician.
Older adults and the elderly typically shouldn't take more than 250 milligrams of EPA and DHA daily. However, when treating high triglycerides, your doctor may recommend up to 15 grams if you have high blood pressure and as much as 10 grams if you have rheumatoid arthritis.
People taking blood pressure medication should talk to a doctor before trying these supplements. Blood clotting: Omega-3s might also affect blood clotting, so people with clotting disorders, bleeding disorders, and those taking clotting medication should talk to a doctor before supplementing with fish oil.
Answer: Long-term use of fish oil is safe as long as the daily dose is not too high and the fish oil is not contaminated, as discussed in the Concerns and Cautions section of our Fish Oil Supplements Review.
"Classical" brown fat is found in highly vascularized deposits in somewhat consistent anatomical locations, such as between the shoulder blades, surrounding the kidneys, the neck, and supraclavicular area, and along the spinal cord. This is the smaller of the two types and has numerous small lipid droplets.
