Weight loss and subsequent weight gain is nothing new, many of us do it. But new research has found that perhaps we should make more effort to keep the lost weight off.
According to new research, entitled Body-Weight Fluctuations and Outcomes in Coronary Disease, that was published in The New England Journal of Medicine on April 6, yo-yo dieting could increase the risk of heart disease.
This can therefore increase the risk of death by heart attack and stroke by those who already have a pre-existing coronary artery disease.
What is yo-yo dieting?
The term yo-yo dieting was originally created by Kelly D.Brownell of Yale University, who was inspired by the children’s toy when describing the up and down movement of people weight.
Has yo-yo dieting been linked with heart disease before?
Yo-yo dieting has been linked to heart disease in the past. With previous studies showing that post-menopausal women were most at risk.
This new study however, looked in particular at those with a history of heart disease, and how yo-yo dieting would affect them.
Sripal Bangalore, the lead author of the study had this to say:
“Back in the 90s there was a study done in patients with no heart disease, who were pretty healthy, that found that weight fluctuations over a decade actually increased the risk of death from heart disease.”
What occurred in this study?
In this new study the researchers looked at a previous study that had examined 9,500 men and women between the ages of 33 and 75.
These participants had a history of heart problems, such as high cholesterol, and coronary artery disease.
In the older study these participants were prescribed cholesterol medication in differing doses, with the researchers monitoring any changes over a 5 year period. During this time their weight was checked too.
What were the findings of the study?
During the 5 years of observation it was found that those who’s weight fluctuated were associated with coronary artery disease.
However, those who were overweight at the start of the study had the biggest risk.
Those with the largest weight fluctuation had a 136% increased risk of stroke, 117% risk of heart attack and 124% more increase of death.
With this information at hand it is clear that not only is weight loss a good idea, but to keep the lost weight off is also desirable.
