In conclusion, after all the explorations of the real-world evidence that looked at the association between eating fast and the risk of developing type 2 diabetes, data support a possible relationship between them. The eating speed is a modifiable risk factor, and eating slowly could be, therefore given a priority as one of the essential lifestyle modifications in preventing the risk of diabetes. Also, interventions should be aimed at altering eating habits, such as education initiatives to reduce eating speed at the population level. However, interventional and long-term studies are warranted to evaluate the causal relationship, and whether avoidance of fast eating is beneficial for the prevention of diabetes.
