Latest research shows that gaining 15 pounds or more over several years puts one at greater risk for heart disease than those who are obese but maintain a stable weight .
Researchers studied nearly 2,500 adults between ages 18 and 30 over 15 years. Most participants gained 15 pounds or more during the study, and 20 percent of these people developed risk factors for medical problems such as heart disease, stroke and diabetes. But only 4 percent of those who didn't gain the weight had the risk factors after 15 years.
Specialists term these risk factors as metabolic syndrome which is characterized by unhealthy traits, such as excessive belly fat, high cholesterol, insulin resistance, glucose intolerance or diabetes, and either a high normal blood pressure or hypertension.
Thus researchers say greater public health efforts should be aimed at weight stabilization over the long term and the easiest way to do it is to decrease the amount they eat one eats and increase ones physical activity.
