Yo-yo diets: a danger to the hearts of young people

A good body is something to which we all aspire but which is very difficult to achieve. Avoiding overweight requires perseverance: balanced diets, exercise and a lot of willpower. However, the social pressure and the search for quick solutions based on the suppression of some food and that quickly reduce the kilos of those who practice them. But, once this process is finished, what has been lost comes back.

These subsistence allowance that make people change weight quickly are known as 'yo-yo' is very common to see in young people. The search for a body adapted to the canons of beauty make these ineffective practices to find the ideal weight and also have many negative effects on the health of those who perform them.


Cardiovascular risk

Health is the first to suffer from these sudden losses and weight gains that have an effect on the human body. In fact those who perform the subsistence allowance 'yo-yo' have a higher risk of cardiovascular disease as revealed by a new study of the Langone Medical Center of NYU, in the city of New York.

The effects of rapid weight fluctuations in the heart of patients were analyzed in 10,000 patients. For 4 years the researchers took note of the weight changes in the participants, the time that had passed to reach them, as well as the hardening of the arteries to analyze the situation of their cardiovascular health.


After taking note of all these aspects, the researchers found that those patients who had experienced more dramatic weight changes were 117% more likely to die from a heart attack. The researchers point out that these sudden changes in BMI end up stressing the body, which ends up leaving sequels in the cardiovascular state of people.

Other problems derived

The researchers also observed that the stress produced by the 'yo-yo' diets in the patients also had Negative effects in other ways. For example, these people were more likely to smoke due to the nervousness that their body experienced. This, together with the state in which the organism remains, increases the risk of cardiovascular diseases.

The authors explain that although losing weight, in cases where it is needed, is not bad, it must be done in an appropriate way. The first thing you have to do is go to a nutritionist to mark the way forward. This specialist will determine some guidelines that will help the patient to find an adequate BMI for their health and maintaining a balanced diet.


This weight loss should be seen as a goal long-term, not as something that you want to get immediately. The loss of kilos should be gradual and not in a short space of time, and should never be the fruit of the diet alone. The menu recommended by the nutritionist should accompany daily exercise sessions.

The specialists also remember that once the correct BMI has been obtained, it must be maintained. Just like losing weight quickly is a problem, earning it just as quickly also makes health resents in the same way. The technique is the same: balanced diet and daily exercise to keep fit.
