Losing weight is a slow battle, but it’s a fight that can always be won with the right weapons. If you’re stalled in your weight loss goals or simply not losing as much weight as you’d like, it’s important to identify the major factors that are keeping you from success. Diet and exercise are obvious culprits, but what about sleep?

Sleep affects a number of physical functions that could either hamper or encourage weight loss, depending on whether or not you’re getting enough slumber. Let’s take a look at how sleep is related to weight loss, and why it’s crucial that you’re getting enough rest every night.

While hormones are obvious culprits behind stalled weight loss, there are two specific hormones—leptin and ghrelin—which are influenced by how much or how little sleep you’re getting.

Leptin is a hormone produced by the fat cells of the body; it influences the parts of the brain that control hunger. Essentially, leptin tells the body when it has had enough to eat. Think of leptin as the satiety, or fullness, hormone.

Ghrelin has the opposite function. It sends the signals to your body that you need to eat. It is thought of as the hunger hormone.

Here’s where all this science gets interesting: In a number of studies, those with restricted sleep saw increases in ghrelin and decreases in leptin. Essentially, when you get inadequate amounts of sleep, your brain begins sending additional hunger signals and curbing the sensation of fullness. Worse, studies further revealed that those with less sleep also have higher levels of body fat than those getting adequate sleep.

Another hormone that impacts weight loss is cortisol. Cortisol is known as the “stress hormone” and is released by the adrenal gland in times of distress. The body becomes stressed when it doesn’t get enough sleep and responds by going into the “fight or flight” mode, releasing cortisol and storing fat. In particular, this hormone encourages the storage of body fat in the abdominal area.

The good news is that sleep is a weight loss factor over which you have control. Setting a regular sleep schedule will not only help you lose weight by positively affecting leptin, ghrelin, and cortisol, it will also boost overall energy levels—energy that can be used for exercise and taking the time to plan meals more carefully. This is why some experts suggest to use supplements that sustain your diet and support weight loss.
