Weight Loss: Intestinal bacteria prevent the diet



The study reveals changes in intestinal bacteria in obese people

Pregnant and over-repeat weight loss try out the diet. But after the abandonment phase, there is a frightening JoJo effect. On the one hand, on the other hand, many return to old eating habits, on the other hand, because the bacteria in the intestine prevent long-term effects. This is the conclusion of the Israeli study.

Scientists from the Weizmann Institute in Israel have found in their recent research that certain intestinal bacteria can be associated with frequent gaining weight after the baby. Physicians have released the results of their research in Nature.

Does intestinal bacteria remember our previous weight?

Are you one of those people who gain weight quickly after a baby? If so, it could be related to bacteria in your gut. "They seem to retain some kind of memory of their last weight," experts say.

The Jo-Jo effect promotes long-lasting changes in intestinal bacteria

The current study was performed on mice. "The results indicate that the so-called yo-yo effect is not just a matter of repetition of unhealthy eating habits," the researchers say. This effect seems to be related to long-term changes in bacterial intestines, which are usually caused by obesity.

Changes in the intestines last for a very long time

Changes in the thickness of the thick intestine last about five times longer than the actual time of eating. This has prompted the mice to quickly regain their weight after the end of the diet, scientists say. If the results can be transmitted to people, it would lead to more evidence-based methods, experts say. The observed effect can explain why some people have such problems that control their weight after a child, says author Eran Elinav of the Weizmann Institute.

The study on mice studied the effect of diet conversion

In the study, obese mice switched from diet to high-fat to a balanced diet. These animals no longer differed from the control group of mice by changing their weight and numerous metabolic factors (such as blood sugar levels), say the medical profession.

Tumor mice retain differences in intestinal bacteria

Researchers have found that prematurely mice retained the differences in their intestinal bacteria, which increase the weight of animals by consuming high-fat foods. When the bacteria from the fat group were inserted into the intestine of the control mice, they also gained weight faster.

The discovery can be a kind of psychological buffer

The observed effect could act as a weight loss swab at times of food shortage, the researchers explain. However, in the case of obesity, this mechanism can lead to faster weight gain.

Changes in intestinal bacteria can last for years in humans

In mice, the microbe slowly changed. Bacteria took six months to re-establish normal microbial control as a control group. This time range is about a quarter of a mouse's life in captivity, explained scientists. Physicians have predicted that a period between months and years can be compared to humans. This can be a really gruesome thought for the sick, says Elinav.

Does a successful microbiotic change require antibiotics?

If a human microbe is subjected to similar changes as in mice, it can help the target group. When the changes in the microbial turn away, this can help maintain a healthy body weight that is achieved after the baby, experts say. However, the consumption of some probiotic yogurt is not enough. The composition of intestinal bacteria is difficult to change. The treatment would eventually require antibiotics to eradicate the existing bacterial population, the researchers explain.

It seems that intestinal bacteria from the diseased turn more energy into fat

The weight gain rate can be predicted based on the composition of the microbial mice, the authors say. The data indicate that a change in metabolism causes intestinal bacteria to convert existing bacteria into energy into fat, the authors explain.

People with persistent obesity return 80 percent after the baby
Other studies have already suggested that people with long-lasting obesity who lose weight through weight gain weight again in 80 percent of cases within 12 months. (As)
