The Truth About the New Fat-Fighting Pepsi

“Pepsi Special” is now being marketed in Japan as a healthy soda that prevents the accumulation of fat.

Japan’s National Institute of Health and Nutrition has labeled this form of Pepsi a “FOSHU” product because it contains fiber in the form of water-soluble dextrin, a substance thought to help people lose weight.  FOSHU stands for “Food for Specified Health Uses.” Sodas previously given the FOSHU label have sold extremely well to their target audience: men and women in their 30s and 40s. The drink will be sold solely in Japan.

Are They Effective?

Presumably, no. Actual evidence of their benefit is scant.

While a 2006 study did demonstrate dextrin’s ability to reduce the amount of fat absorbed from diet, the test was conducted on rats. The effect has never been tested in humans.

Dr. Walter Willett, the Harvard School of Public Health’s chair of nutrition, told Time Magazine, “Unless Pepsi can provide data from controlled studies in humans to the contrary, their claim should be regarded as bogus and deceptive.”


Dietary fiber is known to help us feel fuller after a meal. Because it cannot be digested, fiber also helps naturally escort toxins from the body. What fiber will not do, though, is counteract the overwhelming volume of sugar common to many sodas.

Sugar can disrupt the function of the hormones insulin and leptin, both of which are crucial to maintaining a healthy body weight and proper blood sugar levels. We don’t know the exact sugar content of Pepsi Special because it is not listed on Pepsi’s website.

Just as damaging are the synthetic ingredients commonly found in soda, including high fructose corn syrup,artificial sweeteners, colorings and preservatives. These man-made chemicals can disrupt healthy hormone function and cause you to develop a hormonal resistance to healthy weight loss.

A Better Option

Treat fat-fighting Pepsi like you would treat an as-seen-on-TV infomercial: While it may seem amazing, its actual effect is probably less than impressive. Skip soda regardless of its marketing campaign. Instead, stay hydrated with properly filtered water.

It is important to make sure you’re eating adequate amounts of dietary fiber, as it has a multitude of healthbenefits (from the U.S. National Library of Medicine, the National Institutes of Health):

  • Regulates digestion.
  • Absorbs vitamins, minerals and amino acids.
  • Balances blood sugar.
  • Reduces triglycerides (fats in the bloodstream).
  • May help prevent gastro intestinal disorders and cardiovascular disease.

Fiber is an integral part of quality nutrition, but it is always best to get your fiber from natural sources like sweet potatoes, artichokes and zucchini—not soda.
