article imageInability to taste fat leads to obesity, says study

By Sonia D'Costa     May 27, 2014 in Health
A recent study has discovered a relationship between ability to taste fat and obesity. According to the researchers, people with greater sensitivity to fat eat less fatty food and stay slim, while those with lesser sensitivity overeat and become obese.
The study, conducted by a research team headed by Prof. Russel Keast at the Center for Physical Activity and Nutrition Research at Deakin University, is a build-up on prior research work done by Prof. Keast, who showed that the tongue can not only taste sweet, bitter, salt, and spice, but also fat.
The researchers selected volunteers with normal weight and tested their sensitivity to fat. For several days, the volunteers were made to eat breakfast that was either high in carbohydrate, fat, or protein or balanced. Later, they were invited to a buffet. They found that, on days when breakfast high in fat content was served, those with lesser sensitivity to fat consumed more lunch than those with higher fat sensitivity.
Prof. Keast said that people who consumed more lunch did not receive the “I am full” messages from their bodies that people with more sensitivity to fat received. These messages are very important as they make people stop eating.
Explaining the results of the study, Prof. Keast said: “These results suggest that the ability to taste fat is linked with the fullness experienced from fat. If you do not taste fat or experience the fullness associated with eating fatty food, you are likely to be more hungry and consume more energy after an earlier fatty meal. And as we know, over-consumption of foods—particularly fatty foods—is associated with people being overweight or obese.”
The results of the study have been published in a journal called Appetite.
