In terms of the texture of the cookies, tough cookies are more likely to be fattening. Tough cookies usually contain high starch and fat content, these ingredients will be converted into energy and stored as fat during digestion. In addition, tough cookies tend to have a high calorie content, and consuming too much of them can lead to energy intake exceeding consumption, which in turn leads to weight gain.

In contrast, shortbread cookies usually contain more fat and sugar, but because of their crunchier texture and lighter taste, they may contain relatively fewer calories for the same weight. However, whether it is tough cookies or shortbread cookies, excessive intake can lead to energy intake exceeding consumption, which can lead to obesity.
