Blue-green algae, or spirulina, helps promote reductions in weight, body fat, waist circumference, and triglyceride levels.
Blue-green algae, or spirulina, is a rich source of protein, vitamins, minerals, and essential fatty acids. It also provides antioxidant and anti-inflammatory phytochemicals, and one constituent from spirulina has been found to inhibit pancreatic lipase, a fat-digesting enzyme. In one placebo-controlled trial, 64 people with obesity took 1 gram of spirulina or placebo daily for 12 weeks; those taking spirulina lost 3.5 pounds and reported a significant decrease in appetite, while those taking placebo lost 1.4 pounds and reported increased appetite. Another placebo-controlled trial that included 52 subjects with overweight or obesity found 2 grams of spirulina daily taken during a 12-week reduced-calorie diet program reduced appetite and enhanced weight loss, body fat loss, and waist circumference reduction. In a multi-phase crossover trial, people with overweight or obesity had more improvement in body weight and fitness during a six-week exercise program if they were given 4.5 grams of spirulina daily compared to placebo, and the synergistic effect of spirulina and exercise was more profound in those with obesity. In addition, spirulina had positive impacts on body weight and some markers of fitness even in the absence of exercise. Comprehensive reviews and a meta-analysis of results from five controlled trials add further weight to findings that spirulina can reduce body weight, body fat, waist circumference, and appetite, and may have positive effects on cholesterol and triglyceride levels in people with overweight and obesity.
