She followed it up with a book Meridian Health Protocol called 'Women and Weight Loss Tamasha'; the book has sold 1 lakh copies since its 2011 release.We call Diwekar a celebrity as her clientele includes the businessman Anil Ambani and Bollywood actress Kareena Kapoor. The daughter of chemistry Prof. Rekha Diwekar, Rituja's first book was published by Random House. She is also an avid trekker and undertakes marathon training programs.
But primarily she is a nutrition consultant who offers a particular eating pattern that you are never off your diet. Diwekar also operates a gym and has one by the name of Urja, a fitness studio.Rituja believes that exercise goes beyond what a person does within the confines of the gymnasium. It is for this reason that the country's first ever marathon training program has been initiated by her.
The training program is a 14-week long program and is a tedious exercise in outdoor sports. Presently no other agency or sports institute offers an exclusive course on marathon, so Diwekar is again making a mark in the Indian health sector. Those who have been part of Rujuta Diwekar's marathon program have talked about finding their positive energy again. There are others who have totally turned into running, they are now converts.
