According to a study, the meals of the americans have become irregular and long, to take no calories at night 10-12 hours, could prevent obesity
Scientists from the SALK institute in la jolla suspect that not only lack of exercise and calorie-intensive diet for the epidemic of obesity and diabetes contribute, but also the eating behavior. This has adapted to the way of life in a 24/7 company, which no longer knows no shutdown, in which the sleep time becomes ever quick and in the at least american also all the time to take something to oneself. That could not only make fat, but also sick. Animal experiments at the SALK institute as well as other studies have shown that mause, which could eat very fatty food as often as often often, were much strong obese than those who could eat daily only during a period of 8-9 hours.
The scientists have with a smartphone app that for you an instrument for one "personalized medicine" and to become interesting for hospitals and life insurance, the eating habits of 156 healthy people from san diego logged in the course of 3 weeks to "feedogram" to create as you in your in your "cell matabolism" write a published study. The participants were neither diet, nor did they shift them, they should take everything they aben and drank, photograph or at least enter as text into the app that collected the time and place with. By samples about push requests, tried to find out how often the participants had forgotten to document the dose of food or drink. The scientists derived from it that there is a falstonate of about 10 percent.
From the video of the scientists from the SALK institute.
The americans drink milk or coffee in the morning, like to tea and alcohol in the daytime. Yoghurt is being consumed to fruhstuck, rather sandwiches and burger, during the evening more vegetables and ice cream is eaten. Chocolate and minus is available from 10 o’clock in the morning. Little surprisingly, that at the weekend the breakfast takes place by one to two hours later, the last calorie intake during the night, however, shifts only slightly and mostly less than an hour.
Storing of the biological day and night rhythm
The background of the study is the amption that the changes in the modern life associated with the modern life of the biological day and night rhythm, set at 24 o’clock and connected with phases of activity, sleeping and food intake at certain times, drove to metabolic disorders can. So the seasonal food times are on the "rhythms of gene expression and protein functions" a. When animals, the circadian rhythms of the "corporal watch" genetically or with shift workers through the behavior, this can lead to sanctions. The scientists speak of one "metabolic jet lay".
Experiments with animals have been observed that a frequent feeding of calories steam the molecular circadian rhythms. Conversely, in the case of animal experiments, it may show that with the degree of food intake to a time window of 8-12 hours, without a change in the diet, a stable circadian rhythm is required, which should be accompanied by the decrease of obesity, increased lean mass, long-range sleep, increased stamina, reduced systemic discharging, slowdown in the hearing and other health factors.
The study came to the conclusion that most of the whole day always take some calorie-containing. Those who have the least often eating averages 4.22 "ease events", the 10 percent, the most commonly eat, make this 15.5 times a day. The majority is eating and drinking a time of 15 hours during the day and more and more and again something of which less than 9 hours is taken to be taken during the night. 75 percent of the calories are consumed after noon, a third after 6 pm, less than a quarter to noon. Between 1 and 5 o’clock in the morning the least is taken to himself, the absolute deep was averaging at 4 o’clock. The scientists therefore love the "metabolic day" not after midnight, but starting from 4 o’clock.
The times when the daily routine, due to work, business, school and universitat, was still regularly clocked for the majority of people in a regular way, there is a fresh stuck in a period of up to 12 hours in the morning, a lunch and at noon fruest evening gave a dinner and you slept at night, like many other traditional ways of life are already largely dissolved. There is hardly any more alignment on three main meals, but a rough variation. However, most participants still stated that the daily three main meals.
On average, a meal takes just over 14 minutes. A quarter of the meals was just 1 hour and 25 minutes away from the next, the median was about 3 hours. Only a quarter of the meals were taken after a period of 6 hours and 41 minutes of fasting. The big part of the calories were consumed from spatem afternoon and in the evening hours. According to the calculations of the scientists, the calories that are taken to himself after 18:30, overlapped to keep the body weight stable.
Animal experiments show the effect of a long fast times
The amption that the changing of the lifestyle from an ordered daily routine in about the biological clock to a temporally less and less after the day-night rhythm-ordered adult and sleep, which also affects the dance style is initiated by animal experiments. The scientists from the SALK institute have shown in a study published in the magazine science, that drosophila melanogaster, which could eat only in the day and fattened at night, did not increase and better health values at night.
In a more early study, it turned out that mausa were different depending on the lifestyle with exactly same diet differently for obesity. Mause, which could always eat a highly fatty food at any time, tended to obesity, during mausage with the same food, which were allowed to eat only in a time window of 8 hours, less frequently obese, although during the short time, the same amount of calories take. The mause, who fasted a long time every day, were otherwise healthy. At them were less frequently inflamins, a fatty liver, high cholesterol levels and metabolic disorders.
In an attempt with people, the cause of weight loss is unclear
Even if animal experiments are not transferable directly to humans, the scientists ame that long sailing fast times of 10-12 hours could be more effective to achieve a normal weight than the reduction of calories. But also to take no alcohol in the evening and sleep for 10-12 hours, so that the body watch is again adjusted without disruption by an unregulated 24/7-diet for its allegedly natural sleep-wake rhythms and during sleep the combine calories can burn.
In order to demonstrate this, the scientists turned out eight overweight or obese trial participants, which are usually a few more than 14 hours a day. They were asked to take nothing more for 10-12 hours, which contains more than 5 calories, and fasting the rest of the night. In the 10-12 hours they were allowed to drink water only, no coffee or tea. After 16 weeks, the test persons who have theirs "eating time" an average of 4.5 hours, average seven pounds lost, they reported better sleep and more energy a day.
However, the subjects in contrast to the malls also reduced their sailing calories by 20 percent. That was probably simply by the tangling of the time in which calorium-containing is taken to oneself. The scientists ame that the subjects do not preferred to what they had eaten or drank otherwise, but have left away. For example, the alcohol could play a rough role. However, it is hardly saying whether the long-festive fasting time or the resulting reduction of calories was the cause of weight loss. And general goods also the question of who can afford such a change of lifestyle, which deviates from that of the rest society.
