Obesity dulls the sense of taste, according to research that offers new insights into why some people enter a persistent cycle of weight gain.
Researchers found that within eight weeks of becoming obese, mice lost 25% of their taste buds. The findings suggest that weight gain not only changes appetite but may also fundamentally alter the way taste is perceived.
“Obesity is by nature very complex,”said Robin Dando, a food scientist at Cornell University in New York and senior author. “There are a bunch of different factors that contribute to our state of obesity – we think a change to taste is one of those, and one that people don’t tend to consider.”
The findings are the latest to push back against the assumption that people become obese because they love food more than the average person and so find it harder to resist.
