If a Muslim woman got together with an Indian man, would they become vegetarians?

When a Muslim woman marries a Hindu man, in 90% of the cases, the male converts to Islam. On the other hand, if a Muslim man marries a Hindu woman, then in 99.99% of the cases, the Hindu female converts to Islam. So it is obvious. The vegetarian starts eating beef after marrying a Muslim.
Them that there is nothing more to talk about in the family? Who cares what faith? I'm an atheist but Buddhism and Hinduism do. And cows in India someone kills you? Only the Muslims? In stores probably also sell beef. What are Muslims too?
