As you all know, sleep is one of the four main pillars when it comes to achieving fat loss results. To answer the question we need to look into the matter from two points of impact: indirect and direct.
So indirectly yes, poor sleep does affect fat loss, directly not so much, as directly fat loss will still come down to energy balance or creating a calorie deficit. If you have an amazing sleep, but you’re not in a calorie deficit, you’re not going to get fat loss. However if you have poor sleep, it does affect fat loss indirectly.
Poor sleep & indirect fat loss impact
Why poor sleep affect fat loss indirectly? It’s because when it comes down to having poor sleep what it does it can affect hormones that regulate satiety, and basically overall hunger cravings. So when you have poor sleep, what’s happening is your leptin levels, your hormone that regulates satiety, it actually decreases. So when leptin decreases, the feeling that you get is that you are full from a meal actually is lowered. The feeling that you’re not as full as you wish when you’re eating a meal is obviously not a great thing when it comes to fat loss.
Does poor sleep make you hungry?
Another thing which poor sleep affects is that when leptin comes down it allows for the hunger hormone ghrelin to rise. When ghrelin rises, it signals to your body that you are hungry and the hungrier you are the more likely you are to over-eat. As you can see, the poor sleep indirectly affects fat loss, because it’s going to make you hungrier and have less satiety signals. Not a good combination when you are trying to lose weight.
To summarise, if you want to achieve your fat loss transformation make sure you get proper, consistent and enough sleep time to avoid feeling hungry and poor satiety, otherwise your weight loss result becomes harder to achieve.
