Calanus Oil Combined With Moderate Exercise May Help Increase Fat Loss
Calanus oil is a natural product extracted from marine zooplankton found in the North Atlantic Ocean. It contains the omega-3 fatty acids DHA and EPA and a red pigment called astaxanthin. According to a new study, supplementation with calanus oil in combination with moderate exercise may help mature adults lose fat.
Participants in the study included 134 healthy, untrained adults with an average age of 59.4 and an average BMI of 28. They were assigned to one of four interventions for 12 weeks:
- Aerobic and resistance training 2 times per week;
- Aerobic and resistance training 2 times per week combined with dietary counseling;
- Aerobic and resistance training 2 times per week combined with 2 grams daily of calanus oil;
- Control group.
Body composition, markers of glucose metabolism, and markers of blood lipids were evaluated at baseline and at the end of the study period.
Participants in the calanus oil group saw the highest loss of fat mass, 3.7 pounds, compared to 2.6 pounds in the exercise and dietary counseling group. Participants in the exercise only group only lost .49 pounds of fat mass. Participants in the calanus oil group also saw an increase of 1.8 pounds in lean body mass. No changes in lean body mass were seen in the other three groups.
No significant changes in glucose metabolism markers or blood lipids markers were seen. However, a trend toward improved fasting insulin was seen in the calanus oil and exercise and dietary counseling groups.
The study was conducted by researchers from Leibniz University Hannover and Justus-Liebig-University Giessen. It was published online ahead of print on July 18, 2020 in the journal Nutrients.
