Can omega-3s affect metabolic rate?

Omega-3 fatty acids, specifically EPA and DHA, have been shown to affect metabolic rates in various ways. Research indicates that they can increase resting metabolic rates and fat oxidation during exercise, particularly in older women. For instance, a study reported a 19% increase in resting metabolic rate and a 27% increase in fat oxidation during exercise when omega-3s were administered 1 .

The mechanisms behind these effects could involve the incorporation of omega-3s into mitochondrial membranes, potentially altering how energy is managed and utilized at the cellular level 1 . Additionally, omega-3s are known to promote metabolic homeostasis by enhancing fatty acid oxidation and reducing triglyceride synthesis in the liver. This can help in decreasing liver fat and lowering blood triglyceride levels, which are significant factors in metabolic health 2 3 .

Overall, omega-3s support various aspects of cardio-metabolic health, suggesting their beneficial role in managing metabolic rates and improving metabolic outcomes 4 .
