Obesity and metabolic syndrome are associated with abnormally elevated basal levels of sympathetic nervous system (SNS) activity, which may have the potential to fragment sleep and contribute to daytime sleepiness.
There is also evidence to suggest that obesity is associated with increased daytime sleepiness and fatigue , even in people who sleep through the night undisturbed. Researchers suggest that obesity may change metabolism and/or sleep-wake cycles in such a way that causes sleep quality to deteriorate.
The primary underlying mechanism that makes obese people feel overly tired is likely low-grade chronic inflammation. Fat cells, particularly from abdominal fat, produce immune compounds called cytokines that promote sleepiness, among other effects. Depressed individuals in the study also had high incidence of EDS.

A good night's sleep is one of the keys to good health-and may also be a key to maintaining a healthy weight. There is mounting evidence that people who get too little sleep have a higher risk of weight gain and obesity than people who get seven to eight hours of sleep a night.
Unfortunately, most people cannot have a healthy lifestyle with only four hours of sleep, research suggests. However, personal and anecdotal evidence supporting shorter sleep by using polyphasic sleep suggests otherwise. This means that we cannot say for sure if you can thrive on four hours of sleep.
Restricting sleep for up to 5 days can lead to short-term weight gain [18]. Several cross-sectional studies have indicated that short sleep duration is associated with obesity and the risk of future weight gain in both adults and children [19].
Your energy levels will skyrocket
When you're carrying around fewer pounds, you use less energy to simply go about your day, says Tsai. Weight loss also improves oxygen efficiency, so you won't find yourself out of breath so easily when climbing stairs or hustling to catch the bus.
If your body is carrying excess weight, it can be exhausting. It also puts extra strain on your heart, which can make you tired. Lose weight and you'll feel much more energetic. Apart from eating healthily, the best way to lose weight and keep it off is to be more active and do more exercise.
A larger body, especially a larger fat-free mass, requires more maintenance and thus induces a higher basal metabolic rate or resting energy expenditure.
Just sleep sleeping too little, sleeping too much can also make you gain weight. Studies show that people sleep for more than nine hours are approximately 21 per cent more like to get obese over the six-year period. Experts believe that these weight gain percentage doesn't change even with proper diet and exercise.
OSA is strongly associated with obesity [72]. Obese people must be screened for OSA and disorders that are associated with it. Both obesity and OSA patients have a greater risk of metabolic syndrome [73].
Overall, individuals who increased their sleep duration were able to reduce their caloric intake by an average of 270 kcal per day – which would translate to roughly 12 kg, or 26 lbs., of weight loss over three years if the effects were maintained over a long term.
New research, published in 2022, found not getting enough sleep led to an increase in calorie intake, body fat, and belly fat. The researchers found people who slept four hours a night had a 9% increase in subcutaneous belly fat and an 11% increase in abdominal visceral fat, compared to those who slept 9 hours a night.
For example, someone who is morbidly obese may be able to safely lose around 11 pounds a week, while someone closer to a healthy weight range may only lose as little as 200 grams a week as they have less weight to lose.
Some people may choose to restrict their daily intake to 1,500 calories. While factors such as age, gender, and activity level can cause caloric needs to vary, a 1,500-calorie intake is typically less than the average person requires. As a result, this diet may help some people lose weight.
Losing 30 kg in 6 months requires a combination of a well-balanced diet and a regular exercise routine for weight loss. Create a calorie deficit, focus on whole foods, and include both cardio and strength training exercises to achieve sustainable weight loss.
As your body metabolizes fat, fatty acid molecules are released into the bloodstream and travel to the heart, lungs, and muscles, which break them apart and use the energy stored in their chemical bonds. The pounds you shed are essentially the byproducts of that process.
The CDC state that a person can safely and effectively lose about 1–2 lb a week. Based on those numbers, in a month, a person could safely lose 4–8 lb.
Thermic foods like eggs and cruciferous vegetables burn fat by taking your body longer to digest. Some of the best fat-burning foods are green tea, salmon, apple cider vinegar, and lean chicken.
Elon Musk says he's upped his sleep to 6 hours per night—and that his old routine hurt his brain. Elon Musk, CEO of Tesla, speaks with CNBC on May 16th, 2023. Elon Musk says his days of trying to sleep less and work more are over — at least, relatively speaking.
While making a habit of spending the day in bed or on the couch is not good for anyone, using it as a well-placed conscious tool for your emotional and mental well-being is absolutely ok. As a matter of fact, it's an investment in your health.
