Sunflower Seed Extract May Help Decrease Body Weight and BMI
The worldwide rate of obesity has nearly tripled between 1975 and 2016. A recent study suggests that sunflower seed extract may help decrease body weight, BMI, and waist circumference in obese people.
Fifty adults with a BMI between 30 and 40 kg/m2 and waist circumference greater than 40 inches for men and 34 inches for women participated in the study. Half of the participants took 250 mg of a sunflower seed extract twice daily for 12 weeks, and the other half took a placebo. All participants were monitored throughout the study period for body weight, waist circumference, BMI, fat mass, and lean mass.
Participants in the sunflower group saw significant reductions in BMI and waist circumference, 1.1 and 3.21 inches respectively. In comparison, participants in the placebo group saw reductions of 0.5 and 1.7 inches. Participants in the sunflower group lost an average of 6.8% of total body weight compared to 5.7% in the placebo group.
Participants over the age of 30 in the sunflower group lost an average of 7.7% of their baseline weight, compared to 5.9% in the placebo group. In addition, sunflower group participants tended to have greater changes in fat mass, lean mass, and fat percentage compared to placebo participants.
The study was conducted by researchers from Vidya Europe SAS. It was published on May 15, 2019 in the journal Nutrients.
