It was tough for Anant Ambani during his initial weight loss days as he suffered from chronic asthma. The medication he took, led to 'medicine induced-obesity'

However, Mukesh and Nita Ambani's youngest son was determined to shed weight and he ensured that his medical condition did not come in the way towards achieving his goal

Anant Ambani's progress was slow initially due to his body's balancing issues. Anant would, during his first phase, walk every day for a time frame between 30 minutes to 2 hours. Pic/Instagram

In addition to walking, Anant Ambani pursued resistance training. This involved the use of pieces of equipment like leg press and chest press. Pic/Instagram

Once Anant Ambani lost all the excess weight, he moved on to workouts like planks, push-ups, burpees, and other methods of functional training for toning purposes. He followed light intensity exercises with higher number of reps

Just before his 21st birthday, Anant Ambani was able to achieve the unthinkable. He reached a weight of 100 kgs and ended up weighing less than the weight he lost

The weight loss journey was not all smooth-sailing for Anant Ambani. It has been reported that days when he did not lose a few grams, he would be worried. However, Anant Ambani did not let his insecurities get to him

Many naysayers proposed that Anant Ambani had a little extra medical surgery to help him shed the fat. However, according to his doctors and his parents, it was not possible to perform surgery on Anant Ambani due to his medical condition as it would have been too risky. His weight loss was all natural, a result of regular exercise and a healthy diet. Pic/Instagram
