Bariatric surgery could also alter a person’s taste along as being a solution for obese people. Altering taste could further contribute to weight loss.
Researchers from the Stanford University School of Medicine found that patients who underwent the bariatric surgery felt a decrease in the intensity of taste which led them to further lose weight after three months.
After being told by the patients that they experienced a loss of sensitivity in their taste and felt an aversion for food, the researchers conducted a study.
Bariatric surgery includes several types of weight-loss surgery and it is a collective term. It is the procedure in which the subject’s digestive system is being changed in order to help him lose weight. It is done by limiting the amount of food a person could eat or by lessening the nutrient absorption.
33 healthy non-obese people were used as control for the study and another 55 obese patients suffering from obesity and about to undergo the bariatric surgery were used as well. They each were subject to a test after 3, 6 and 12 months after the surgery. It was a taste test that was using flavor-saturated paper strips to see their ability to identify bitter, sweet, sour, salty and savory tastes.
Chief of bariatric and minimally invasive surgery at Stanford, Dr. John M. Morton said:
“Even before surgery, the tests showed the obese patients were uniformly less taste sensitive than normal weight patients. Obese patients may seek to derive satisfaction through volume rather than taste appreciation.”
42% of the subjects said the food didn’t taste good after the surgery and most of the subjects (87%) said they noticed a change in their taste perception after the surgery.
Morton also said that patients no longer preferred salty foods after the surgery.
The subjects who had less intensity in taste lost 20 percent more weight in three months than those whose taste intensity grew.
Former president of the ASMBS and medical director of bariatric surgery at the Hamilton Medical Center in Dalton, Georgia, Dr. Jaime Ponce said the study provides exceptional new insight on taste after bariatric surgery and:
“More research is needed to see how we can adjust for taste perception to increase weight loss,”
