Spirulina has been used by some people as an aid to weight loss. It has been found that many people experience a reduction in appetite if they take a few grams of spirulina thirty to sixty minutes before a meal. This can be attributed to the high fiber and protein content along with low calorie content leading to a filling of fullness. When the stomach sends the message that it is full to the brain a lower appetite results.

Large quantities are not required to receive such benefits because of the fact that spirulina is so nutrient rich. Spirulina has also been used to aid in detoxification.
