Does a good night's sleep affect weight loss
If you have to get up very early every now and then, you may have experienced this before: You sit around limp and still have cravings, as if you had just cut down a small forest. Because a sleepless body prepares itself for hard times. It switches to energy-saving mode and sends out hunger signals.
The consequences have been shown in several studies. People who sleep less than six hours a night eat more and are more likely to gain weight than well-rested contemporaries.
But not only the duration, but also the times of sleep influence the weight. People with a late daily rhythm - who get up late and go to bed late - exercise less and eat more. This also applies if you do not spend more hours in bed than an early riser.
An Australian study found that teenage night owls sit on their bum 27 minutes longer a day than a comparison group who got up earlier. A study by Northwestern University in Chicago showed that people with a late daily rhythm ate almost 250 kilocalories more per day than early risers - especially in the evening. Their fast food consumption was about twice as high.
What is it about the trend diet?
The cause is not entirely clear: maybe people simply have fewer opportunities to get fresh, light food and exercise late at night. However, a disturbed biorhythm may also be responsible. The researchers suspect that those who stay awake for a long time and then sleep a good part of the day can disrupt the internal clock in such a way that the control of appetite, satiety and metabolism changes. Experiments on rats have shown that animals with a disturbed day-night rhythm gained weight, even though they did not receive more food overall than conspecifics who slept soundly at night.
However, all of these findings do not mean that you can simply reverse them and lose weight through long, regulated sleep. On the contrary: Those who spend more than nine hours a day in bed are also more likely to gain weight - probably because they move less.
Now Detlef Pape's slim-while-sleep method is based on a certain diet at the same time. The aim is to reduce carbohydrates before sleep in order to boost fat burning at night. But this has not been scientifically proven. Basically it is true that a lack of carbohydrates encourages the body to get its energy from other sources - namely from the love handles. But: There is no evidence that the restriction of carbohydrates only or especially at night has an effect.
Struggling with complicated diet regulations in the evening or even going to bed hungry is at least superfluous, and in some cases even counterproductive. It could disrupt sleep and then lead to food cravings the next morning.
