The yo-yo effect is particularly harmful to the heart

Most people have been on a diet at least once in their lives and many of them have already experienced the unloved yo-yo effect. Staying on a diet is usually difficult. It is all the more annoying if the lost pounds are put back on in no time and can be read on the scales during daily use. In a recent study, researchers have also found that the yo-yo effect also damages the heart.

After the diet, it's mostly like before the diet

If you eat normally again after a diet, the so-called yo-yo effect often occurs quite quickly. This means that by returning to the usual diet, the kilos lost are usually back faster than expected. It can get even more annoying if the weight increases higher than before the diet. These fluctuations in weight are a considerable burden for our cardiovascular system.

The metabolism adjusts itself to a diet

During a diet, which is naturally reduced in calories, the metabolism adjusts to it. If you eat as usual after a successful diet, your metabolism is still geared towards the low level of calorie-reduced time. The result is that the body uses less energy and therefore stores fat faster.

On the one hand, all the energy that has been put into the diet has been wasted, and on the other hand, the yo-yo effect also has a detrimental effect on heart health, the researchers report on the results of their study on the American Heart Association portal. The more often a yo-yo effect occurs, the worse the heart is.

Requirements for the study

Only women who had lost at least five kilograms through a diet and who increased it again within a year were eligible for participation in the study.

Great study

There were 485 women averaging 37 years of age involved in the study. In the past, almost all of these women had experienced a yo-yo effect up to a maximum of 20 times. Most of these subjects were still overweight. Here it becomes clear that diets usually do not lead to permanent weight loss. And the more often a woman has experienced the yo-yo effect after completing a diet, the worse the health of the heart.

Furthermore, it was found that younger women, who had never been pregnant, had started dieting madness much earlier and their heart health was worse. Conclusion: The earlier you experienced yo-yo effects, the worse it looks for heart health.

Heart health was assessed as follows

The heart health of the participating women was assessed based on these seven factors:

  • Did the women have high blood pressure?
  • Did the women have problems with their blood sugar levels?
  • Did women have high cholesterol?
  • Were there smokers among them?
  • Was the woman overweight?
  • Were the women active in sports?
  • How do women eat?

Is weight loss possible without a yo-yo effect?

However, it will also take into account that most Yo-yo women had poor heart health in advance due to their permanent overweight. So it is highly recommended both for the heart and for a permanently healthy body weight to stop trying short-term diets.

Lifestyle change

Instead of going on a diet after another, you should rather change your lifestyle and diet permanently so that you have a happy and healthy body weight. This would regulate blood pressure in the long term, level the blood sugar level and improve cholesterol levels. (fm)
