There were researches that shows mental work induces an increase in appetite. The research team measured a the spontaneous food intake of 14 student correspondents after each of three tasks: relaxing in a sitting position, reading and summarizing a text, and completing a series of memory, attention, and vigilance tests on the computer. And it shows a relative increase in the calorie intake.
This must be the reason why some people tend to eat more when feeling stressed or after a hard day mental work. Here are some reasons why people feel hungrier:
- Seeing food, which makes your body anticipate eating.
- Time of day. Your body is conditioned to eat at certain times.
- Drinking alcohol, which can impair your judgment and make you eat more than normal.
- Eating refined carbs, which generates a rapid rise in blood sugar, followed by a subsequent “crash” that makes you want more food.Portion size. Studies show that the larger the portion, the more you’ll eat.
- Eating too fast, which allows you to consume more food before your body has a chance to let you know it’s full (it takes about 20 minutes for this to happen, so you should wait at least 20 minutes before going back for seconds).
- Not sleeping enough, triggers hormone imbalances that boost your desire to eat.
