There is no scientific research that shows that lecithin aids in weight loss. In fact, lecithin supplements may actually cause weight gain due to the fact that it contains fatty acids and is thus highly caloric. There is just no validity to the rationale behind the weight loss claim. Lecithin makes sure that the fat and cholesterol that is travelling through the blood stream stays solvent in the water so that it will not attach to the artery walls. Even though lecithin does disperse fat in water and keeps fat from clogging the cardiovascular system, this does not mean that the subcutaneous fat that we associate with being overweight is just dissolved and flushed out by lecithin.
Humans get lecithin from cell production and from the nutrients in our diets.
The estimated amount of lecithin in a human's diet is 50mg, which is sufficient for the body's proper functioning. Any healthy person whom consumes a well-balanced diet does not need to take lecithin supplements. Not much is known about the relationship between the average person's dietary patterns, food processing and lecithin intake. Further studies of lecithin intake in the American diet would prove beneficial to resolve this question of the necessity of lecithin supplements. But even research on lecithin's effects on these other ailments are inconclusive and irreplicable.
