The results of experiments that some volunteers took part in to assess the sweetness of drinks showed that those who regularly drank sugary drinks and were fatter rated the sweetness of the same drink lower than those of normal size  This shows that their taste buds are less sensitive to sweetness  The results also show that people who are fatter tend to choose sweeter foods subconsciously  This suggests that eating too much sugar may form a vicious circle, that is, eating sugar regularly will lead to a decrease in the sensitivity of taste buds to sweetness, and a decrease in satisfaction caused by eating the same amount of sugar, which will subconsciously ask for more sugar
The volunteers were able to evaluate the sweetness of the drink more accurately.
 The result is that eating too much sugar leads to obesity
