"The study is novel because for the first time we are showing that increase in Body Mass Index (BMI) is not happening equally across the board," S. V. Subramanian, professor of Population Health and Geography at the Harvard School of Public Health, told IANS.
"Obese and overweight people are gaining weight rapidly in low-and middle-income countries, including India, while those who are severely undernourished are not experiencing similar weight gains," said Subramanian, the senior author of the study.
