Benefits of Krill Oil Supplementation During Alternate‐Day Fasting in Adults With Overweight and Obesity: A Randomized Trial
Authors' conclusion
KO supplementation during body weight loss attenuates the decline in FFM and muscle strength.
Study context
- Population
- Healthy adults with overweight; completers age 39 ± 10 years, BMI 31.1 ± 4.2 kg/m², 25 women and 16 men41 completed
- Comparison
- Krill oil vs vegetable oil placebo during 8-week alternate-day fasting
Primary result
As reported in the abstract
Change in FFM · 8 weeks
Krill oil (KO)
−0.2
± 0.9 · kg
Placebo
−1.2
± 2.0 · kg
P < 0.05
Further findings
| Outcome | KO | Placebo | P value |
|---|---|---|---|
| Change in HGS · 8 weeks | −0.2 ± 0.5 kg | −0.9 ± 0.7 kg | P < 0.05 |
| Body weight reduction · 8 weeksNot different between groups | −4.6 ± 1.4 kg | −4.5 ± 1.9 kg | P > 0.05 |
- Change in handgrip strength (HGS): changes in HGS different between groups; no change with KO (p > 0.05), reduction with placebo (p < 0.05)
