Summary

This study looked at whether taking krill oil (a source of omega-3s) while following an alternate-day fasting diet helps adults with overweight or obesity lose fat without losing muscle strength. Fifty healthy adults were randomly assigned to receive either krill oil or a placebo for 20 weeks, which included a weight-loss phase and a maintenance phase. Researchers measured changes in body composition, muscle function, and inflammatory markers.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: krill oil (omega-3 fatty acids)
What this could lead to: If it works, this could point toward a way to lose weight while preserving muscle strength and reducing inflammation.
What could go wrong: This is a small, early-stage study (50 people) with no phase designation, so results may not apply to everyone. The supplement may not provide additional benefit beyond the fasting diet alone.
