Early weight loss can cut diabetes risk

Early weight loss can cut diabetes risk

New research has found that the risk of diabetes associated with obesity can be reversed if obese young people make efforts to lose weight before middle-age.

The team of researchers from St George's University of London wanted to look at the effect of BMI in earlier life on the risk of heart attack, stroke or diabetes in later life, three major diseases in which obesity is an established risk factor, Zee News said.

To look at a possible link the team measured the body mass index (BMI) of 7735 middle-aged men between 40 and 59 years of age.

The measurements were then compared to data collected on the BMI of the men aged 21, taken from their military service records or previous participation in a medical study.

From the 4846 men that provided complete data, and taking into account their varying ages and smoking status, the researchers found that men who had had a high BMI at aged 21, but had lowered it by aged 50, had similar or even lower rates of diabetes than those who had a normal BMI when they were younger.

However a similar reversible effect was not seen for the risk of heart attack or stroke, and a high BMI when aged 21, although associated with a higher risk of diabetes in later life, showed no effect on the risk of heart attack or stroke later in life.

Lead researcher Professor Christopher Owen commented on the results saying, "Even in men who carried out UK National Service and were relatively thin in early life compared to more recent men, higher levels of fatness in early adult life appear to be associated with later diabetes. However, effects of early body mass appear to be reversible by subsequent weight loss. These findings have important implications for Type 2 diabetes prevention, especially in more recent adults with high levels of obesity."

Men who were obese at aged 50 however, still showed an increased risk of diabetes, as well as an increased risk of heart disease and stroke.

According to the World Health Organization (WHO) worldwide obesity has more than doubled since 1980.
