The Claim

In obese women, high-dose omega-3 supplementation (4.8 g/day EPA+DHA) for three months has no significant effect on body weight, fat mass, or lean mass, suggesting that metabolic and inflammatory improvements can occur independently of changes in body composition.

How it works
1 study reviewed
In plain English

Taking a high dose of omega-3 fish oil every day for three months doesn't make obese women lose weight or change their muscle or fat levels — but their metabolism and inflammation might still get better anyway.

See the scientific wording

In obese women, high-dose omega-3 supplementation (4.8 g/day EPA+DHA) does not significantly alter body weight, fat mass, or lean mass over three months, indicating that metabolic and inflammatory improvements occur independently of weight loss.

What the research says

1 study
  1. Study: Differential effects of high dose omega-3 fatty acids on metabolism and inflammation in patients with obesity: eicosapentaenoic and docosahexaenoic acid supplementation

    This study gave obese women a high dose of fish oil for three months and found they didn’t lose weight or change body fat—but their blood sugar and inflammation got better anyway. So, the health benefits happened without losing weight.
