How to effortlessly lose weight with spirulina
Spirulina is a weight loss supplement. If overweight or obese people take 2 grams of spirulina every day for 6-12 weeks, they might just lose 1.8 kg without having to change their lifestyle. This is the conclusion of a meta-analysis of five trials that Iranian researchers published in Complementary Therapies in Medicine.
The researchers traced 5 studies in scientific literature in which, for 6-12 weeks, overweight or obese subjects had received supplements with 1-4.5 grams of spirulina per day - and in which the researchers subsequently determined the effect of the supplementation on body weight.
The researchers then aggregated the results of the studies and analyzed them again.

Supplementation with spirulina resulted in an average body weight reduction of 1.76 kilos.
The optimum dose seemed to be 2 grams per day.
The greater the body weight of the test subjects, the more weight they lost as a result of supplementation, the researchers discovered when they compared the test subjects with a BMI of 25-30 to those with a BMI of more than 30.
In human studies, spirulina supplementation improves insulin sensitivity, [Eur Rev Med Pharmacol Sci. 2017;21(10):2473-81.] and reduces appetite. [BMC Complement Altern Med. 2017;17(1):225.] The researchers suspect that these effects explain how spirulina induces weight loss.
