Yoyo Dieting? You’re Now at a Higher Risk of Heart Attack and Stroke!
Yoyo dieting is frustrating for millions of Americans. As soon as you think you’re making progress, up goes the reading on the scale. One year, you’re in the middle of your healthiest BMI, the next, you’re edging on obesity again.
That said, a recent study has shown that yoyo dieting isn’t just a matter of frustration. For many people, it can also be a matter of health, or even life and death. The study determined that people whose weight fluctuates up and down again are also more likely to see fluctuations in their blood pressure, blood sugar and cholesterol levels. When that happens, the risk of heart attack and stroke rises, too.
Yoyo Dieting is Harmful to Health
It hasn’t come as much of a surprise that yoyo dieting isn’t good for you. After all, sending your weight down, only to have it spike back up again places many of the body’s systems under strain.
We’ve long known that obesity and continually raised blood pressure, blood sugar and cholesterol is unhealthy. After all, those factors increase the risk of heart attack and stroke. However, this new research shows that the fluctuations from yoyo dieting also places health at risk. This, according to Dr. Seung-Hwan Lee, the senior author of the study from the Catholic University of Korea, located in Seoul, South Korea.
Fluctuating Metabolic Risk Factors
The study focused on yoyo dieting, which is different from previous research. Most studies have examined the impact of being continually obese. They’ve looked into the risk factors associated with people whose weight and other metabolic risk factors remain high. However, as people increasingly try to lose weight, the trends are changing. Increasingly, people are losing weight only to gain it back.
The impact of that type of weight trend hasn’t seen much attention from the research community. This research analyzed data from over 6.7 million people from 2005 through 2012. The data had been collected by the Korean National Health Insurance System. The people whose data was used did not have any history of diabetes, heart attack, high cholesterol, or high blood pressure. They’d each had a minimum of three medical exams during the seven year study period.
Findings of the Yoyo Dieting Study
During the follow-up, data showed over 21,000 heart attacks, 22,000 strokes and 55,000 deaths. When compared to people whose metabolic factors varied very little, those with more fluctuations, such as from yoyo dieting, were 2.3 times more likely to die during that span of time. They were also 40 percent more likely to have a heart attack or stroke.
