Sleep and Weight

Sleep and weight

Sleep and weight, are they related?  We discuss the relationship between weight loss and getting the all mighty zzzz’s. Check out our YouTube videos and follow us on Facebook.

Sleep and Weight (Loss)

Every year, a phenomenon in January takes place – New Year’s Resolutions. Studies suggest that up to 85% of people’s resolution include weight loss. If that includes you, please read on as there is some vital information that will help you push forward throughout the year.

Healthy food and exercises is the general focus of this goal, but your sleep habits can actually sabotage any efforts to reach your goals.

Yoga, sleep, health

Sleep actually helps manage your appetite. Sleep is the only time your brain can achieve certain goals such as memory consolidation, cell regeneration and ones body chemistry tries to becomes balanced.

The balancing of your bodies chemistry is imperative to weight loss due to three specific hormones. Leptin, Ghrelin and Insulin. All three are important individually and all affect each other when proper sleep is not
maintained, which in turn effects weight management.

Leptin and Ghrelin work together to regulate your appetite. Ghrelin tells your body it’s in need of fuel ( hungry) and Leptin tells your body that its full. After a poor night’s sleep the brain is not properly balanced, you might feel groggy and your brain releases more ghrelin in hopes of fueling your body to feel better, at the same time Leptin slows its release so you eat more before feeling full.


Weight Loss and eating

This need for fuel can lead to poor food choices, quick energy foods are normally high in calories, carbohydrates and high in fat. With Leptin in short supply the body doesn’t register it’s full and your hungry even after meals. The brain’s chemistry actually overpowers our sense and will power over snacks and unintended meals.

Now we know why we eat more when proper sleep hygiene isn’t present in the short term but there are long term effects as well. This is where that third hormone Insulin comes in.

Insulin is a hormone created in the pancreas. Its job is simply to convert (metabolize) incoming calories into energy. This is the fuel our body uses at a cellular level.

Insulin is only released into the bloodstream when there are calories that need to be processed. When incoming calories aren’t properly metabolized, blood sugar (glucose) remains in the blood when it should be absorbed by the cells to use as fuel. This can lead to insulin resistance. When the body is unable to recognize insulin in the system this can slow the metabolism which can lead to weight gain and type 2 diabetes.

Sleep better

Poor sleep leads to increased Ghrelin which makes us eat more which is completely at odds with insulins ability to metabolize food. If this becomes a regular habit, Leptin levels may be normal in the bloodstream but
increased consumption can lead to Leptin resistance where the brain ignores the message to stop eating.

Poor sleep not only leads to chemistry imbalances, it also drains daytime energy, mood changes, depression and anxiety which can lead to emotional eating and other poor choices such as foregoing that walk to binge watch Netflix.

Man sleeping

There are lots of reason for sleep deprivation. The most common reasons include:

1. An unidentified sleep disorder such as OSA (sleep apnea) or Insomnia
2. Social expectations
3. Medications may interfere or fragment sleep
4. Poor sleep hygiene

Diet and exercise are certainly major factors to weight loss but without good quality sleep, your valiant efforts could be thwarted.  If you suspect sleep apnea is disrupting your sleep, click here to download our RX form and take it to your doctor on your next visit.
