Did you know that there have been studies proving that if you don’t get 7 – 8 hours of sleep per night, you tend to be heavier? It also depends on the quality of sleep to, so if you have sleep apnea and don’t use a machine to help, it will not matter how much sleep you get, it will not be good. Your hormones are effected by your sleep! Have you ever experienced a sleepless night followed by a day when no matter what you ate you never felt full or satisfied? If so, then you have experienced the workings of leptin and ghrelin. Leptin and ghrelin work in a kind of “checks and balances” system to control feelings of Hunger and fullness. Ghrelin, which is produced in the gastrointestinal tract, stimulates appetite, while leptin, produced in fat cells, sends a signal to the brain when you are full. So what’s the connection to sleep? “When you don’t get enough sleep, it drives leptin levels down, which means you don’t feel as satisfied after you eat. Lack of sleep also causes ghrelin levels to rise, which means your appetite is stimulated, so you want more food,” In a study by Stanford University, 1,000 people were asked about their sleep habits and were weighed and their levels of ghrelin and leptin were measured. Those who slept less than eight hours a night not only had lower levels of leptin and higher levels of ghrelin, but they also had a higher level of body fat. What’s more, that level of body fat seemed to correlate with their sleep patterns. Specifically, those who slept the fewest hours per night weighed the most. Sleep Apnea is the one issue that derails this for some people. If you have it, you could get 8 hours of sleep but it feels like you only got 4. People that have sleep apnea also tend to have higher levels of leptin. If treated, it not only helps you get get a good rest but it does help with weight loss! Snoring is a symptom as well as if people notice that when your sleeping, you stop breathing for a bit, then resume. I had sleep apnea and used a machine to sleep early on while my weight was in the 400’s. I, now, no longer have to use it!
