When I was visiting Bangladesh in 2004 I noticed that peasants in the rural areas were shorter, wirier and "tighter" in their physique than many people in Dhaka. Though Dhaka residents weren't tall, they did strike me as taller, and a substantial subset were endowed with a plump visage which one rarely saw among rural peasants.
