How taste and smell differences relate to weight and eating

Researchers want to understand why people with obesity may experience taste and smell differently than people without obesity. This study will compare taste and smell abilities in about 350 people—some with obesity and some without—to learn how these senses influence what people eat and how much they eat. The findings could help doctors create better treatments for obesity in the future.

Obesity is a major health problem in America, and changing eating habits has been difficult. Scientists believe that differences in how people perceive taste and smell might play a role in obesity, but very little is known about why these differences exist. Understanding this connection could lead to new and more personalized ways to help people manage their weight.
