Cornell University in the United States has studied the tongues of obese and normal mice and found that eating a diet high in fat can reduce the number of taste buds  Taste buds are structures on the tongue, including about 100 cells  After the mice gained weight, the rate of death of mature taste buds became faster, while the growth rate of new cells became slower  The loss of taste buds can lead to dull taste, which makes it difficult for obese people to eat a certain diet, because if they want to taste the same delicacy as normal people with 25% more taste buds than they do, they have to eat heavier food
This means eating more sugar, fat and calories
The way that taste bud achieve metabolism.
