Karl: Can you really gain weight from lack of sleep?
Megan: It’s not that lack of sleep equates to weight gain, rather, it’s the behaviors that result from the lack of sleep. Your brain actually responds differently to hunger cues and desires junk food. A sleepy brain also lacks the ability to reign in on impulses to eat. You also might be staying up later or just having more awake time, which could mean more caloric intake that may or may not be necessary. You may also experience increased levels of the stress hormone cortisol, which again makes your food decision making distorted and can tamper with blood sugar levels. Notice some of your habits on days when you don’t get enough sleep. You might find that you eat more or feel more hunger. Tune into your body and what it is telling you.
