When you don’t get enough sleep, hunger and appetite increase.
You’ve probably noticed that when you don’t get a good night’s sleep, the next day your whole routine is out of whack. Research has uncovered that part of this is due to an imbalance in metabolism caused by sleep deprivation. There’s a link between sleep and weight gain: When you don’t get enough sleep, hunger and appetite increase.
“This can lead to poor food choices, such as carb loading in order to get an energy fix,” said Meredith C. Sweeney, M.D., bariatric surgeon. “When that energy wears off, you’re back to feeling sluggish and looking for something to give you a boost again.”
Suspect a Sleep Disorder?
The first stop should be your primary care provider before poor sleep starts affecting your health.
In addition, complex changes in brain function after poor sleep make it harder to practice self-control and stimulate the brain’s reward center, making that candy bar extra enticing.
A Slippery Slope to Obesity
Add feeling too fatigued for activity and exercise, and over time poor sleep becomes a slippery slope that can lead to obesity.
“Especially if you are trying to lose weight, getting enough sleep is critical to success. There’s strong evidence that sleep is the missing ingredient with people who are having difficulty losing weight,” Dr. Sweeney said. “Weight gain also can lead to sleep apnea, which creates another factor contributing to poor sleep.”
If that’s not enough, sleep deprivation increases insulin resistance, meaning blood retains more sugar and the body produces more insulin to compensate.
“The excess insulin makes you hungrier and tells the body to store calories as fat,” Dr. Sweeney said. “This can lead to Type 2 diabetes.”
The bottom line is when you get plenty of sleep, it’s easier to make healthier food choices.
