If you found yourself asking “why am I always hungry”, you can check if you are a restless sleeper. Cuz getting poor sleep or not enough rest can affect two hormones that are linked to influencing your appetite. “Not enough sleep causes rising levels of ghrelin, which stimulates appetite, and lowers levels of leptin, which causes feelings of fullness.” This is what I read from a medical article. Also according to this article, it’s believed serious fatigue also creates a hunger response in your system as a way of getting extra energy from the food you consume. You might be hungry all the time because you’re not getting enough sleep, but aiming for about 7 to 8 hours a night should get both your hormones and energy levels back on track.
