One possible explanation is that increased mechanization has reduced calorie needs. Even in rural areas bus services have increased greatly and the use of cycles and motor-cycles has reduced walking time.
Tractors combine harvestors, dehusking machines, health milling machines and other such devices have greatly reduced the physical labour involved in agriculture. Even in urban areas, mechanization has reduced the need for physical effort. It is rightly said that there are large variations in calorie requirements from person to person.
