Losing weight on an empty stomach can lead to malnutrition and affect health. Being hungry for a long time is very unhealthy. It is no problem to keep a regular diet for three meals a day, and it is 1 to 2 hours between meals. However, if you are hungry for more than 3 hours, there is a great risk of stomach trouble.

In addition, losing weight on an empty stomach will slow down the body's metabolism and make it more difficult to lose weight.
