F Blocker, as the name suggests, is a weight loss supplement that works by blocking fat. Its main ingredient is Chitosan which purportedly absorbs fat and allows it to be excreted from the body without being digested. This substance is contained in many fat blocking and absorbing formulas. People who take this product are advised to make dietary changes such as reducing the consumption of fatty foods and eliminating trans and saturated fat. Absolute Nutrition, the developer of this product, claims that this supplement was formulated after years of working with professional athletes.

Absolute Nutrition promotes living a healthy lifestyle that includes taking the supplement F Blocker by giving dietary tips and fat reducing hints leading to weight loss. At the same time the site uses the pleasure principle as a platform to push the product telling dieters that they can still enjoy eating fatty foods while blocking it. F Blocker does not contain any other ingredient commonly associated with weight loss such appetite suppressants and metabolic boosters.
