Hormonal Hijack: How Sleep Deprivation is Making You Fat

Everyone knows to avoid junk food and exercise regularly, but how many of us give the same priority to our sleep?

Approximately 40% of American adults report sleeping less than 7 hours each night, with even more reporting not feeling “well rested.” Far too many of us use caffeine to wake up and sedatives to calm down. However, caffeine does not actually wake us up. Rather, it simply masks fatigue by blocking adenosine receptors. Further, the human body is not designed for constant chemical dependence just to get through the day.

For metabolic health, quality sleep is paramount. Research shows poor sleep raises your hunger hormone (ghrelin) by 28% and drops your fullness hormone (leptin) by 18%. Ghrelin is the gas pedal; it doesn’t just make you hungry, it spikes your cravings for high-calorie, starchy food. Leptin is the brake; when it drops, your brain doesn’t receive a fullness signal, making overeating inevitable.

So, when you wake up early from a late night out, your body craves sugar, hyper palatable food, and oversized portions, and thinks it’s hunger. It’s not. It’s your body looking for the quickest energy source. It’s not just a matter of willpower but a biological shift that makes overeating inevitable.

I once had a client who needed to lose over 100 pounds. Not only did I train her in the gym, but we also discussed her diet and lifestyle. During one of our sessions, I asked about her sleep, and she revealed she did not sleep well. When I asked why, she said it was because her cat sleeps in her bed and keeps her awake. And when I suggested she put the cat in another room? She looked at me like I wanted to murder her own child!

No matter what I said, she was not budging from having that cat with her all night. Ultimately, she lost about 30 pounds in a few months with me, but I truly believe this cat kept her from getting the deep sleep necessary to reach her full weight loss potential.

Quality sleep is a superpower. It drives physical restoration, supports mental health, and ensures you are optimized on every level. Everyone is at their best when they get a good night’s sleep, and at their worst when they don’t, regardless of what anyone may claim. This is why we should not make big decisions or have serious conversations when tired.

The stakes are higher than just a bad mood, too. Lack of sleep also spikes injury risk due to impaired motor skills. Sleep-deprived driving is equally as impairing as drunk driving. In fact, 24 hours of total sleep deprivation is the physiological equivalent of legal intoxication in every state. We (hopefully) won’t show up to work drunk, but we show up exhausted all the time. Therefore, the hours before bed should be treated with reverence- a time to wind down, not wind up.

You will perform at your best when you prioritize your sleep. Shohei Ohtani, arguably the world’s greatest baseball player, travels with a custom mattress because he understands how vital sleep is for recovery and performance. While you don’t have to be this extreme, the ROI on high-quality bedding and a restful environment will always outperform any supplement. In fact, good sleep is the closest thing to a performance-enhancing drug a human can utilize.

As someone who has struggled with sleep, here are five science-backed sleep tips:

• Go to bed and get up at the same time every day, even on weekends.

• Get 10 minutes of sunlight upon waking and before looking at your phone. This will set a chemical timer for melatonin production when it is time for bed.

• Remove all screens from the bedroom at least one hour before bedtime. Use a bedside alarm, if necessary.

• Make your bedroom a sanctuary, dark, cool, and relaxing. The bedroom is only for two things, and they both start with the letter S.

• No caffeine or stimulants. If you do have caffeine, wait at least 60 minutes after waking, taper down by noon, and keep it below 200mg, so your circadian rhythm will not be disturbed. Waiting 60 minutes after waking to consume caffeine also allows your body to clear adenosine naturally, preventing the mid-afternoon crash.

To find success from these steps, you will probably need to change your habits while applying discipline, patience, and consistency. However, even if you follow all these steps, you will still have some sleepless nights. Everyone has emergencies and major life stressors, and no one is perfect 100% of the time.

On these occasions, you can leverage higher doses of creatine, which can rescue your brain. Creatine is simply a combination of three amino acids (arginine, glycine, and methionine) that your body naturally produces. It is highly researched, safe, affordable, and beneficial for everyone - not just athletes or bodybuilders. It also mixes easily in liquid or food with very little taste.

Additionally, you can take Magnesium Glycinate or L-theanine, which will support your body’s natural transition into sleep. However, try not to use sedatives because sedation and unconsciousness are not sleep. Substances such as Ambien, THC, or alcohol will cause significant REM suppression and bypass the natural process of sleep.

These substances switch the brain off and fragment sleep, rather than usher it through the necessary cycles for complete mind and body restoration. REM suppression also dysregulates blood sugar and appetite hormones (leptin and ghrelin). Therefore, pharmacological sedation and natural sleep are opposites that only seem similar on the surface.

Lastly, nothing will help you deal with stress better than consistently good sleep. Chronic stress raises cortisol, which promotes insulin resistance. This makes it physiologically harder for your body to burn fat when you are stressed or tired.

So, before you try the next fad diet or exercise routine, examine your sleep and make sure you don’t have a “cat” in your room keeping you from reaching your full potential.
