According to the Massachusetts Institute of Technology, the idea that anything you eat before going to bed will turn into fat is not true, but there are good reasons not to sleep after a meal. When you take a nap, it is difficult for your body to digest the last meal, which can lead to problems such as indigestion and possibly increased risk of stroke.

When The time you eat is not so important, how much you eat. In order to lose weight, you must consume more calories than you consume. It doesn't matter if you take all the extra calories in the first thing in the morning or the last thing in the evening. There are other dangers of eating late at night, including weakened judgment and weakened willpower, not fatigue. When you are hungry at midnight, spending time making salads may not be as appealing as ice cream or completing the remaining pizza. Making an unhealthy decision before going to bed means you have no chance to burn extra calories.
Heartburn
Lying on your back after a big meal may feel good at first, but when your body is at rest, your digestive system will work hard. Heartburn is caused by an excess of stomach acid, which causes a burning sensation to spread from the stomach to the chest and sometimes to the throat. It can also be accompanied by a nap. This may make it difficult for ge to get a good night's sleep.
Acid reflux
Gastroesophageal reflux disease, also known as GERD or acid reflux, is caused by the inability of the valve between the stomach and esophagus to be completely closed. This will allow stomach acid to return to your throat, which can cause a burning sensation. Lying on your back after a meal can exacerbate this situation. If left untreated, gastric acid flushing into your esophagus may damage the mucous membranes.
