How to lose weight and sleep better at the same time
Have you ever noticed that when you are tired you eat more?
You may even feel ravenous and spend your day grazing the office freebies in the kitchenette. Your portions may be getting larger and the number of times you eat during the day may be increasing in an attempt to get more energy and combat fatigue.
Rest assured this is not your fault! It is not a lack of willpower. The answer may lie in your sleep and sleep apnea may be the culprit responsible for your weight gain.

Why do we pack on the pounds when we are sleep deprived?
When we’re sleep deprived, the hormones that control hunger and appetite start sending out faulty messages.
There are four hormones that control hunger and appetite:
- Ghrelin tells the body to eat
- Leptin tells it to stop eating
- Cortisol makes us crave sugary foods when we’re stressed
- Insulin stores calories
When we’re short on sleep, we produce more ghrelin (making us want to eat) and less leptin (the hormone that tells us to stop). On top of that, we produce more cortisol due to the stress caused by lack of sleep, so we crave sugary foods. And we produce extra insulin, which leads the body to store glucose in fat cells . . . so we gain weight.
It’s no wonder that as much as we might try, if we’re lacking sleep, we will invariably turn to food. We simply cannot combat the signals our bodies are sending us. Moreover, with an increasing amount of cortisol, we’re likely to give in to junk food cravings.
Sleep apnea and weight gain: a vicious cycle
Here’s what happens:
- In obstructive sleep apnea the airway becomes blocked (obstructed) during sleep, which causes a pause in breathing.
- When we stop breathing our oxygen levels drop, which triggers the brain to tell us to wake up and breathe.
- However, we don’t wake up completely (these sleep interruptions are called “micro-arousals”).
- It’s these micro-arousals that disrupt our sleep architecture and cause us to wake up in the morning feeling as if we haven’t slept a wink.
Gaining weight can cause us to sleep less and sleeping less can make us eat more! This vicious cycle can turn into a nightmare.
But there is hope: The cycle can be broken, starting with a proper night’s sleep. And the good news is Apnea Health can help you achieve a good night’s rest.
How to break the cycle
The first step is to get tested for sleep apnea.
If you have OSA symptoms and feel that your sleep is not restful, it’s important to talk to your doctor about it.
Apnea Health offers simple, fast and effective home testing. You can also contact us for a free evaluation to see if sleep testing is right for you.
Here’s a checklist to review with your doctor for signs of sleep apnea.
- Loud snoring
- Occasionally waking up during the night feeling that you’re choking or gasping
- Restless sleep
- Having a sore or dry throat in the morning
- Having a headache in the morning
- Sleepiness, low energy or fatigue during the day
- Feeling sleepy behind the wheel
- Weight gain
- Erectile dysfunction
- Forgetfulness, mood changes, and a decreased interest in sex
Will CPAP treatment help with weight loss?
Yes! A three-month study of CPAP users published in the New England Journal of Medicine showed a marked reduction in body mass index, as well as a mild to moderate decrease in blood pressure and cholesterol levels 1.
That’s three good reasons for people with sleep apnea to use their CPAP device every night!

Is it okay to stop CPAP treatment after losing weight?
Treating sleep apnea and restoring sleep will obviously have an impact on your health and weight. You’ll stop feeling drowsy and fatigued. You’ll want to be more active, and with your new energy you might take up exercise, which will support your weight loss. And, of course, your hunger hormones will work normally.
Still, even if you snore less and feel you no longer suffer from sleep apnea, you should never stop CPAP without checking with a sleep medicine specialist first. That’s because there is no 100% guarantee that your sleep apnea will be completely eliminated.
Although being overweight is a cause of sleep apnea, sometimes other factors are present too – such as ear, nose and throat abnormalities (including nasal obstruction, tonsillar hypertrophy, large tongue base, elongated uvula or palate), or facial abnormalities. If these factors are present, sleep apnea will not necessarily disappear with weight loss.
So you’ve lost that extra weight. What next?
After you’ve lost weight, it’s a good idea to visit your sleep clinic. It’s possible that the pressure setting on your CPAP machine will need adjustment because your airway has become less restricted.
After that, start thinking about other healthy lifestyle changes! With cravings under control, you can take the time to make nutritious meals. The extra energy you get from being well-rested can help you get a good workout, either outdoors or in the gym. You’ll find that with the help of Apnea Health, a whole new outlook begins with a good night’s sleep!
