With 18.25 biceps to show, Prateek now has a new mission: he would like to propagate the vegetarian-as-bodybuilder notion and see more bodybuilders go veggie.
And how does he feel to be so apolitical in a family of leading politicians?
Politics only interested him ever when he was eight years old, Prateek says.
"I would see my father on TV, and then try to imitate him: 'Brothers and sisters, I am now just a young boy...' my speech would go, the young man says, chuckling.
And what does he have to say about his father Mulayam Singh Yadav and brother Chief Minister Akhilesh Yadav
"Netaji has a great memory, he remembers everyone," says Prateek. "Akhilesh bhaiyya has a vision, he wants much changed," he says
A beautiful body, and politically correct: that's Prateek.
