4 Ways Skipping Sleep Can Make You Gain Weight

April 10, 2015 2 min read

Getting enough sleep is vital to your health but it is also vital to maintaining a healthy weight. "No question about it: Sleep is vital to every aspect of health, but it's especially important in controlling weight," says David Katz, MD, founding director of Yale University's Yale-Griffin Prevention Research Center. "We tend to think of sleep as downtime, but a better sleep comparison would be spa treatment, physical therapy, rehab, and rejuvenation, all rolled into one." Here is why sleep is so slimming:

Getting more than 6 hours of shut-eye keeps your appetite in check...

A new study published in The American Journal of Human Biology shows that getting fewer than 6 hours of sleep a night can impact appetite regulation. Researchers looked at brain images of participants and found that lack of sleep alters the secretion of the hunger hormones ghrelin (the hormone that makes us hungry) and leptin (the hormone that lets us know when we're full). So, you end up feeling hungrier and over eat, usually foods high in sugar, which increases your risk for developing obesity, heart disease, diabetes and high blood pressure.

...and makes junk food look less tempting.

A bad night's sleep can create a weakness for high calorie, low nutrient foods, says a study published in The American Journal of Clinical Nutrition. When participants got less than 4 hours of sleep a day, they were more likely to respond to food stimuli (like the sight and smell of bacon and pastries), than when they slept for 9 hours. Scientific Reports published research that says that not only do we consume more food after a sleep deprived night, we consume more fat.

A 30-minute power nap reverses the health effects of poor sleep.

If you didn't get your full hours last night, have a power nap. According to Journal of Clinical Endocrinology & Metabolism (JCEM), a 30 minute nap can reverse the hormonal impact of a poor night's sleep which can reign in some of your hunger, bolster your immune system and relieve stress.

Regularly cutting sleep short by even a half-hour adds pounds.

If you are staying up a little later to finish your television show or set your alarm early to work on something first thing, a new study from Weill Cornell Medical College in Qatar says that losing a half hour of sleep every day for a year can lead to a 72 percent increased risk of becoming obese and 39 percent increased risk of developing insulin resistance which promotes type-2 diabetes. Hmm, like I needed another reason to nap, are ya with me?

Shipping & Delivery

Due to COVID-19, shipping systems the world over are experiencing abnormal delays. There is an enormous demand on postal and delivery services as online shopping has skyrocketed, due to store closures and stay-at-home mandates. This is an unprecedented situation, and we are working around the clock to fulfill your orders as quickly as possible. To be clear, we are filling orders in 4-6 days, and we are shipping immediately after that. Once shipped, our shipping partner, UPS, will get your order out to you as quickly as possible. Thanks for your support and understanding.

Are you in Canada? Specifically, are you outside of a metropolitan centre? We need to alert you to a disruption in shipping due to COVID-19. Our preferred shipping provider, UPS, has informed us that they cannot guarantee express shipping for many locations. We have also seen that packages delivered to Toronto, Ottawa, Vancouver, etc, are not waylaid, but packages delivered to areas just outside of these cities are being held in transit for days or even weeks. UPS has discontinued their guarantee of 1-4 day delivery, which you can read more about here. Therefore, we can guarantee early fulfillment but not early delivery of our goods from our warehouse to your door at this time.

We want you to start your fitness journey with us as quickly as possible, that’s why we send every package to the USA & Canada via expedited or standard shipping (whichever is faster) with our partners at UPS. Once your order has been processed successfully we try to have your shipment prepared within 4-6 business days, and it typically takes 2-4 days to get to you once it leaves our warehouse.

We currently DO NOT SHIP to locations outside of the US and Canada. We DO NOT ship to a P.O. Box number.

We ship all of our physical products with UPS, from our warehouse location in Kingston, Ontario, Canada. Sometimes delivery can be delayed by circumstances out of our control, like postal & custom delays, back-ordered products or incorrectly entered shipping addresses. If there is a delay at Customs, a representative of UPS may contact you to provide your identification in order to receive your package. Please do this ASAP: Customers will be responsible for any additional shipping fees for failure to provide the required information to release a shipment.

Make sure when checking out and paying for your order that all of your information entered is correct! If you notice a mistake in your address, please try to contact us before your order is processed for shipping to avoid any missed shipments or delays. As soon as we process your order for shipping, you will receive a shipping confirmation email that contains your UPS tracking number. You can head on over to the UPS Website to see where your products are. Note: tracking information may take 1-2 business days to be updated in the UPS system

If you are not home when your package is delivered, BodyRock is NOT responsible if it is stolen. Please contact us if this happens to you and we will provide you with all the information needed to take the next steps.
