Bariatric surgery, which shrinks the stomachs of those who undergo it, may lead to less capacity for tasting food, according to research conducted at the Stanford University School of Medicine in California.
The study, presented at the American Society for Metabolic & Bariatric Surgery and The Obesity Society (TOS), surveyed data on 55 obese patients who underwent the procedure, and 33 healthy people who did not.
Eighty seven percent of the bariatric surgery patients reported a change in taste perception after the operation, with 42 pecent adding that they consequently ate less.
"Compared to the normal weight [participants], obese patients had consistently less taste sensation," study author Dr. John M. Morton told FoxNews.com. "My speculation is that obese patients may make up for lack of taste intensity with volume."
The Agency for Healthcare Research and Quality (AHRQ) notes that metabolic/bariatric surgery is the most effective and long lasting treatment for severe obesity and results in significant weight loss.
