Researchers have identified how obesity dulls the sense of taste, driving people to eat larger quantities of calorie-rich foods to satisfy their cravings.
More than one third of American adults are obese and that number is growing rapidly, creating an urgent need for a better understanding of the disease and how it can be treated.
Obesity has been linked to a reduced taste sensitivity that leads people to seek out foods that are richer in sugar, salt and fat to get the same amount of satisfaction.
