In short
- Snoring is more common in people who are overweight, and Cleveland Clinic says fatty tissue in the neck can press on the throat when its muscles relax during sleep.
- In a small 1995 study of heavy snorers, men who lost at least 3 kg went from about 320 to 176 snores an hour, and three who lost an average of 7.6 kg nearly stopped snoring.
- A large Wisconsin study found a 10% weight loss predicted a 26% drop in breathing pauses during sleep, while a 10% gain predicted a 32% rise.
- A German guideline recommends weight loss for all overweight snorers, while noting that studies of weight loss for snoring alone are scarce.
- Nasal strips, side sleeping and, for open-mouth snorers with a clear nose, mouth tape can help while weight loss takes time, but none of them treat sleep apnea.
Extra body weight makes snoring more likely, mostly because fat around the neck can narrow the airway once your throat muscles relax in sleep. Losing weight, if you need to, is standard snoring advice, and small studies suggest even a few kilograms can make a real difference for some people. The research is thin, so pair weight loss with other simple changes in the meantime.
How does weight affect snoring?
Snoring happens when the airway is partly blocked and the tissue around it vibrates as you breathe. The NHS explains that the tongue, mouth, throat and nasal airways relax and narrow when you're asleep, which is what lets them vibrate. Anything that narrows the airway further makes snoring more likely. Cleveland Clinic says snoring and sleep-related breathing disorders are more common in people who have overweight or obesity. The NHS lists being overweight among the things that make you more likely to snore, alongside smoking, drinking too much alcohol and sleeping on your back.
The neck is the key area. Cleveland Clinic explains that during sleep, fatty tissue in your neck can press on your throat and block your airway when your throat muscles relax. Its advice is that losing weight can take some of that pressure off and limit your snoring.
Weight is one factor among several, though. Cleveland Clinic also lists age, family history, enlarged tonsils or adenoids, a deviated septum, nasal congestion and alcohol.
Does snoring stop with weight loss?
Research: limited (what this means)For many people who are overweight, snoring does appear to ease with weight loss. Both the NHS and Cleveland Clinic list losing weight, if you need to, as a way to cut down on snoring.
The most direct study is small and old, but the results are encouraging. In 1995, researchers in Florida followed 19 men who snored heavily but had no other symptoms. They had already tried sleeping on their side and using a decongestant nasal spray, which made little difference to how often they snored. They then joined a six-month weight loss program, and 12 of them lost weight.
The nine men who lost at least 3 kg went from about 320 snores an hour to 176. Three men who lost an average of 7.6 kg almost stopped snoring altogether. Men who gained weight saw no improvement. The authors concluded that weight loss seemed to be responsible for most of the benefit.
The study is worth reading with its limits in mind. It included 19 men and had no separate control group. Weight loss also didn't change the men's apnea-hypopnea index, a measure of breathing pauses, so the effect it found was on the snoring itself.
What do guidelines say about weight loss for snoring?
A 2019 German guideline on snoring in adults, published in Deutsches Ärzteblatt International, lists weight loss as one of the main conservative treatments. It recommends a lower body mass index for all overweight snorers, at its highest recommendation grade.
It is also honest about the gaps. The guideline found that studies of weight loss were only available in people with sleep apnea, not in people who simply snore, and it lists whether snoring improves after weight loss in overweight snorers as an open research question. So the advice rests on good reasoning and related evidence rather than a large trial in snorers.
How is weight linked to sleep apnea?
Weight is closely linked to sleep apnea, and this is where the evidence is stronger. A study published in JAMA in 2000 followed 690 randomly selected working adults in Wisconsin, with an average age of 46 at the start, and checked their breathing during sleep twice, four years apart. Compared with people whose weight stayed stable, a 10% weight gain predicted about a 32% rise in the number of breathing pauses and shallow breaths per hour of sleep. A 10% weight loss predicted about a 26% drop. A 10% gain also predicted a sixfold increase in the odds of developing moderate to severe sleep-disordered breathing.
The AASM says the risk of sleep apnea increases with the amount of excess body weight. If you've gained weight and your snoring has become louder, or come with new symptoms, that's worth taking seriously. See sleep apnea and high blood pressure for one of the reasons it matters.
How should you go about losing weight?
Lose weight through better nutrition and regular exercise, since there's no special diet for snoring. Cleveland Clinic suggests losing weight by improving your nutrition, exercising regularly and, if you need support, working with a weight management specialist. For reference, the AASM notes that an adult with a body mass index of 30 or higher is considered obese.
In the 1995 study, the men who lost at least 3 kg saw a clear drop in snoring, so a modest loss may be enough to notice a change. Our guide to exercise and sleep covers how activity affects your nights.
What else helps while you lose weight?
Side sleeping, not smoking, less alcohol and avoiding sleeping pills can all help while you lose weight, and you don't need to wait for weight loss to get quieter nights. The NHS lists sleeping on your side, not smoking, not drinking too much alcohol and avoiding sleeping pills among its main snoring tips. Our guide to sleep position and snoring goes into the first of those in more detail.
If your nose feels blocked at night, nasal strips are an easy add-on. Cleveland Clinic says strips lift the nostrils open to improve airflow, and calls them inexpensive and easy to find. In a small randomized trial of 12 people with chronic rhinitis, a real strip lowered snoring from about 258 to 173 snores an hour compared with a placebo strip, though it didn't make the snoring quieter. Our guide to how nasal strips work explains how they open the nose.
If your mouth falls open as you sleep, the NHS suggests something that holds it closed or keeps you breathing through your nose. Mouth tape does that simply for adults who breathe comfortably through their nose. Try our nose test first, then read does mouth tape help with snoring? and how to start mouth taping.
Check this first. Skip mouth tape and see a doctor if you snore loudly, wake up gasping, have been told you stop breathing in your sleep, or can't breathe comfortably through your nose. More on safety
If you want to try nasal strips, our pick is TitanAir Nasal Strips.
Strips and tape can make the nights easier while weight loss does its slower work. Neither one treats sleep apnea.
When should you see a doctor?
The AASM says snoring paired with choking, gasping or silent pauses in breathing is a reliable indicator of sleep apnea, and lists excessive daytime sleepiness and obesity as other warning signs. The NHS advises seeing a GP if lifestyle changes aren't helping, if your breathing stops and starts while you sleep, or if you feel sleepy during the day. Our guide to snoring vs. sleep apnea explains the difference between the two.

Common questions
Does losing weight stop snoring?
It often helps people who are overweight. Both the NHS and Cleveland Clinic list losing weight as a way to reduce snoring. In a small 1995 study, heavy snorers who lost at least 3 kg snored about 45% less, though not everyone's snoring went away.
How much weight do you need to lose to snore less?
There's no set figure. In one small study, men who lost 3 kg or more snored significantly less, and three who lost an average of 7.6 kg nearly stopped. Men who gained weight saw no improvement.
Why does weight gain make you snore?
Cleveland Clinic explains that fatty tissue in the neck can press on the throat and block the airway when the throat muscles relax during sleep. That narrowing makes the surrounding tissue more likely to vibrate.
Can thin people snore?
Yes. Weight is only one cause. Cleveland Clinic lists others including age, family history, enlarged tonsils or adenoids, a deviated septum, nasal congestion, alcohol and sleeping on your back.
Does weight gain raise the risk of sleep apnea?
Yes. The AASM says the risk of sleep apnea increases with the amount of excess body weight. In a study of 690 adults followed for four years, a 10% weight gain predicted a sixfold rise in the odds of developing moderate to severe sleep-disordered breathing.
What can I do about snoring while I lose weight?
The NHS suggests sleeping on your side, not smoking, not drinking too much alcohol and avoiding sleeping pills. Nasal strips can help if your nose is blocked, and some adults with a clear nose use mouth tape if their mouth falls open at night.
Can losing weight cure sleep apnea?
Losing weight can make sleep apnea less severe, but it isn't a guaranteed cure. In a Wisconsin study of 690 adults followed for four years, a 10% weight loss predicted about a 26% drop in breathing pauses and shallow breaths per hour of sleep. If you might have sleep apnea, see a doctor for a diagnosis and a treatment plan.
