WHY YOU NEED TO SLEEP TO LOSE WEIGHT
For anyone trying to lose weight or just get healthier, a chronic sleep debt is a giant eraser scrubbing away at all those healthy choices you’re making with your diet. Here’s a quick reminder of why sleep is so important for weight loss.
Sleep matters for weight loss for two big reasons. First, there’s the behavioral aspect: how much sleep you get influences what you’re likely to put in your mouth. Second, there’s the metabolic aspect: sleep deprivation profoundly changes what happens to that food once it’s already down the hatch.
Many scientific studies have shown that if they’re allowed to choose their own diet, sleep-deprived subjects will eat more food, especially more junk. Assuming you aren’t living in a metabolic ward, you too have the ability to choose your own diet – and you too will likely go for the “comfort food” in the face of sleep deprivation. Specifically, sleep deprivation is a huge risk factor for sugar cravings and overeating high-carb junk food.
Insulin sensitivity is the metabolic capacity to handle eating carbs – to use them for energy, instead of storing them as fat. A reduction in insulin sensitivity means that you’re more likely to store food as fat. In this study, for example, either sleeping 5 hours a night or sleeping at the wrong time (the shift work pattern) increased markers of inflammation.
This study makes it even clearer: “sleep deficient humans…exhibit a proinflammatory component; therefore, sleep loss (weight gain) is considered as a risk factor for developing cardiovascular, metabolic, and neurodegenerative diseases (e.g., diabetes, Alzheimer’s disease, and multiple sclerosis).
