According to foreign media reports,A large study published Friday in the European Journal of preventive cardiology, the Journal of the European Heart Association, found that exercise does not eliminate the negative effects of overweight on heart health."One can't be" fat but healthy, "said study author Dr. Alejandro Lucia of European University in Madrid, Spain. "This is the first nationwide analysis to show that regular exercise is unlikely to eliminate the adverse health effects of excessive body fat. Our results refute the claim that a positive lifestyle can completely negate the harmful effects of overweight and obesity

There is some evidence that fitness may reduce the adverse effects of overweight on heart health. Studies have shown that in adults and children, "fat but healthy" may be similar to "thin but unhealthy" cardiovascular health. Dr. Lucia said. "This has led to controversial recommendations for health policy that give priority to physical activity and fitness rather than weight loss. Our research attempts to clarify the link between activity, weight and heart health

The study used data from 527662 working adults insured by a large occupational risk prevention company in Spain. The average age of the participants was 42 and 32% were female.

Participants were divided into normal weight (BMI 20.0-24.9 kg / m2), overweight (BMI 25.0-29.9 kg / m2) or obese (BMI 30.0 kg / m2 or above). In addition, they were grouped by activity level: 1) regular exercise, defined as the minimum amount of adult activity recommended by the World Health Organization (who); 2) insufficient activity (some moderate to vigorous exercise per week, but less than the minimum amount of who activity); 3) no exercise (no exercise). Cardiovascular health is determined by the three major risk factors for heart attack and stroke, namely diabetes, high cholesterol and high blood pressure.

About 42% of the participants were normal weight, 41% overweight and 18% obese. Most people do not like to exercise (63.5%), 12.3% do not exercise enough, and 24.2% exercise regularly. About 30% have high cholesterol, 15% have high blood pressure, and 3% have diabetes.

The researchers investigated the association of each BMI and activity group with three risk factors. At all BMI levels, any activity (whether meeting the WHO minimum standards or not) is associated with a lower likelihood of diabetes, hypertension, or high cholesterol than no exercise at all. Dr. Lucia said. "It tells us that everyone, no matter how heavy they are, should take physical exercise to protect their health."

At all body weights, the risk of diabetes and hypertension decreased with increased physical activity. "The more exercise, the better, so it's better to walk 30 minutes a day than 15 minutes a day." He said.

However, overweight and obese participants had a greater cardiovascular risk than their normal weight peers, regardless of the level of activity. For example, obese people who exercise are about twice as likely to have high cholesterol, four times as likely to have diabetes, and five times as likely to have high blood pressure as inactive normal weight people. "Exercise doesn't seem to compensate for the negative effects of being overweight, and the overall picture of this finding was observed when men and women were analyzed separately," Dr. Lucia said

"Fighting obesity is as important as not exercising, it should be a joint battle," he concluded. Weight loss, along with the promotion of an active lifestyle, remains a major goal of health policy. "
