Excessive weight gain can be associated with how many calories a person uses per day, and over time, which takes in food. Such conclusions about the biological clock and their relations with the meal began coming American scientists studying the behavior of animals.
The study was conducted on mice, some mice were not restricted in the diet throughout the day, other animals were given feed with an interval of 8 hours. It turned out that the first group of animals was protected from metabolic changes in the body, and they have not developed the deposition of excess fat.
"Every body has a clock," said the study's lead author Panda Satchidananda of the Salk Institute for biological studies. Biological clocks affect the liver, intestines, muscles, allowing them to work with minimum or maximum efficiency. Metabolic cycles affect the utilization of cholesterol, glucose decomposition with the formation of energy, and these processes are included in the meal. Therefore, the mouse who ate during the day indefinitely, fell into biological cycles, in which food was cut effectively without fat accumulation. If in the metabolic cycle misses a meal, it is the deposition of calories and develops obesity.
The same principle sleeping and waking, which is associated with the individual hours of the person, due to the influence of genes. If we have enough sleep, we feel tired all day, and as a consequence work less efficiently.
Work from Paul Hardin of the University of Texas, published in the new issue of the journal Current Biology associated with the study of eating behavior in fruit flies. Taste factors depend on the time of day. All flies a natural instinct to search for food constantly.
But it turned out that there is an internal clock of Drosophila, which control the sensitivity to the same food, but also affect how often flies eat. Found to have a high sensitivity to sugar in the daytime, and much less occurs at night. If you eliminate these hours, flies eat much more food.
Sex Hardin says: "Dependence on biological time exists in humans. Further study of data on biological time to understanding how to control "watch" the meal, it was possible to find an effective way to combat obesity in humans".
