Indians have for over a thousand years been deliberately bred to be a servile weak people.
It's entrenched in their caste system. It is genetic for them, fitness forums all over the internet are awash with jeets bemoaning their permanent skinnyfat physiques and their seeming total inability to make gains. This is because their masters bred them to weak. It is not in their genes to be strong.
This of course also filters down into how they were fed. Much like how the ancient greeks did not allow slaves to eat meat, so the Brahmins taught the lower castes to be vegetarians and only threw them scraps of meat to eat with their gruel.
This is also why traditional Indian food essentially revolves around the concept of making a slop that can be spread as thinly as possible in order to flavor the otherwise plain rice that they subsist on.
The thick sauce curries with large chunks of meat that you think of when you think of Indian food is not actually Indian cuisine. It was invented by the British.
