The Claim

In obese Mexican women aged 25–45, daily supplementation with 4.8 grams of omega-3 fatty acids (3.2 g EPA + 1.6 g DHA) for three months is associated with a significant reduction in fasting insulin and HOMA-IR, with these improvements persisting one month after stopping supplementation, suggesting a durable effect on insulin sensitivity independent of weight change.

In plain English

Taking a specific type of fish oil daily for three months may help lower insulin levels in obese Mexican women between 25 and 45, and the benefit might last even after they stop taking it — without needing to lose weight.

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 omega-3 fish oil for three months, and even after they stopped taking it, their blood sugar control stayed better — without them losing weight. So yes, the omega-3s had a lasting positive effect.
