New study findings indicate that high blood pressure and unhealthy levels of cholesterol risk were similar in who are obese (but were now a healthy weight) and those who had always maintained a healthy weight.
Major weight loss appears to reverse most of the heart disease risks linked to obesity, according to a cross-sectional analysis of the US adult population presented at the Annual Meeting of the European Association for the Study of Diabetes (EASD). More than 40% of adult Americans have obesity (BMI of more than 30kg/m²) and one in 10 have severe obesity.Body weight is directly associated with heart disease risk factors.
As BMI increases, blood pressure, bad cholesterol, other abnormal blood fats, blood sugar, and inflammation also increase. These changes increase the risk for heart disease, stroke, and death from cardiovascular disease.
However, little is known about whether the effects of obesity persist in those who subsequently achieve and maintain healthy weight.
To find out more about this, researchers analyzed cardiovascular risk factors in 20,271-non-elderly US adults (aged 20-69 years) by comparing those who had obesity in the past but had been maintaining weight for at least a year (326) to those who had a healthy weight (6,235) and those who currently have obesity (13,710).
The study findings are published in the journal Diabetologia.
They used data from a series of cross sections, collected biennially from the 1999-2013 National Health and Nutrition Examination Survey to compare the prevalence of high blood pressure, elevated blood cholesterol and type 2 diabetes between the groups.

Compared to those who were always healthy weight, people who used to have obesity had three-fold higher odds of diabetes than those who never had obesity.

These findings are from observational associations rather than cause and effect, and they cannot rule out the possibility that other unmeasured factors (including socioeconomic status) or missing data (e.g., dietary habits, physical activity behaviors) may have affected the results.
The study relied on self-reports of disease diagnosis and medication, as well as highest-ever body weight (which might not be accurate).
Finally, this study indicates that losing weight and maintaining it can not only prevent but also reverse significant health problems.
