She admitted in the same interview that by age 23 she was told that she would never be able to conceive; her older children Akash and Isha were born through in vitro fertilisation. At 20 years old, Anant hired celebrity personal trainer Vinod Channa to help him get fit, and it was during this 18-month process that his mother Nita felt inspired to join him.

How Nita Ambani spends the family fortune “A child does what his mother does, so I couldn’t be seen eating while putting him on a diet,” Nita told The Times of India . “So I went on a diet along with Anant. Whatever he ate, I ate. Whenever he exercised, I did too. If he went for a walk, I would go along. By virtue of being his mother, I lost weight.

There are so many children who have this, and mothers feel shy admitting it.” View this post on Instagram Good Morning ️ A post shared by Nita Ambani ️ (@nita_ambani3) on Oct 25, 2020 at 8:26pm PDT Getting into a routine with her son helped Nita achieve her goals, and she found herself returning to the weight she was before getting pregnant. 5 controversies the Ambani family can’t seem to get away from Mrs. Nita Ambani, Mr. Akash Ambani & Mr. Anant Ambani proudly pose with the @IPL trophy! #CricketMeriJaan pic.twitter.com/w13guqPh3U — Mumbai Indians (@mipaltan) May 22, 2017 Anant had a strict exercise regime that, for the most part, Nita followed, too.
