Your CPAP Machine Can Help You Lose Weight (New Study!)



Lose Weight Faster With Your CPAP


Obese adults with obstructive sleep apnea who follow a calorie-restricted diet can lose more weight if they also use a CPAP machine.

According to a new study, “CPAP can actually facilitate weight loss,” says study leader Yuanjie Mao, MD, an endocrinology fellow at the University of Arkansas for Medical Sciences in Little Rock.  He presented the findings in New Orleans at Endocrine 2019, the annual meeting of the Endocrine Society.


Combine Diet and CPAP Use For Best Weight Loss


Yuanjie Mao, M.D., Ph.D., was the lead researcher on the study and is a fellow physician in the Division of Endocrinology and Metabolism in the UAMS College of Medicine Department of Internal Medicine.

Mao is one of four participants in the Endocrinology and Metabolism Fellowship at UAMS. Peter Goulden, M.D., associate professor of endocrinology and metabolism, oversaw Mao’s work. At the Endocrine Society meeting, Mao’s work was selected for presentation and was featured for its especially newsworthy findings.

The study was featured at the Endocrine Society’s annual meeting, ENDO 2019, March 23-26 in New Orleans.

“This study highlights the importance of sleep quality and hints at the possible underlying neuroendocrine changes associated with poor sleep,” Mao said.

“These results suggest that physicians should recommend a combination of weight loss and CPAP treatment for obese patients with obstructive sleep apnea.”


Obstructive Sleep Apnea and Obesity




The most common cause of obstructive sleep apnea in adults is obesity. Wearing a CPAP machine during sleep is the first-line treatment.

However, some people may think the CPAP will not be needed if they lose weight and attempt to lose weight without initiating CPAP treatment.

In contrast, this study found that when obese people who have obstructive sleep apnea try to lose body weight by dietary calorie restriction, starting CPAP machine treatment can actually result in more body weight loss.


Overweight sleep apnea patients who use a CPAP machine lose more weight than those who don’t.


The study looked at patients undergoing a 16-week intensive calorie restriction program that included exercise, weekly individual counseling and cognitive behavioral therapy.

Some in the group with sleep apnea were treated with CPAP and others were not. The CPAP-treatment group saw a larger absolute weight loss than the non-CPAP group.

Obesity Has Become a Worldwide Pandemic


The prevalence of obesity has been recognized as a worldwide pandemic. Obesity is abnormal or excessive fat accumulation and is associated with earlier death related to several conditions, such as type 2 diabetes and cardiovascular diseases.

Worldwide, obesity increased by 47.1 percent in children and by 27.5 percent in adults between 1980 and 2013. In 2016, globally 39 percent of adults were overweight, and 13 percent were obese.


Obesity in the U.S.



Obesity has continued to grow within the United States.

At this point, two of every three American men are considered to be overweight or obese, but the rates for women are far higher.

The United States contains one of the highest percentage of obese people in the world.

In fact, the United States has the highest rate of obesity within the OECD grouping of large trading economies. From 23% obesity in 1962, estimates have steadily increased.


Estimated (Age-Adjusted) Percentage of US Adults with Overweight and Obesity


All (Men and Women) Men Women
Overweight or Obesity 70.2 73.7 66.9
Overweight 32.5 38.7 26.5
Obesity (including extreme obesity) 37.7 35 40.4
Extreme obesity 7.7 5.5 9.9

As shown in the above table

  • More than 2 in 3 adults (70.2 percent) were considered to be overweight or have obesity
  • About 1 in 3 adults (32.5 percent) were considered to be overweight
  • More than 1 in 3 adults (37.7 percent) were considered to have obesity
  • About 1 in 13 adults (7.7 percent) were considered to have extreme obesity
  • More than 1 in 3 (38.7 percent) of men, and about 1 in 4 (26.5 percent) of women were considered to be overweight
  • Obesity was higher in women (about 40 percent) than men (35 percent)
  • Extreme obesity was higher in women (9.9 percent) than men (5.5 percent)
  • Almost 3 in 4 men (73.7 percent) were considered to be overweight or have obesity; and about 2 in 3 women (66.9) were considered to be overweight or have obesity.

Final Thoughts


Obstructive sleep apnea occurs when the muscles in the throat intermittently relax during sleep and block the patient’s airway.

CPAP machines are worn over the nose or mouth and use a constant stream of air to keep the patient’s airways open as they sleep.

If your doctor has CPAP use, know that in addition to easing your nighttime breathing, your CPAP also makes it easier to lose weight.
