3 Dr. Tanmay a senior cardiothorasic surgeon is concerned about depleting health index in
India. Being a CMO (Chief Medical Officer) of Government Hospital , he is given the
responsibility to probe into the situation by health ministry. One of the major reason found in

authorities were instructed to guide some segments of hotel industry to prepare zero-oil food
with all basic nutrients required by body. The concept was unique within itself and was
appreciated by health conscious people. Only selected restaurant’s outlet were called for a
need based training. In this process first approach was to eliminate unnecessary items from
menu card and add calorie value as well as precautions if any along with the price. Next
standard time for processing the order was fixed to avoid waiting time. Movement of waiters ,
cook and other staff was closely monitored. Within 6 months the concept gained momentum in
market. Identify by quoting lines the following:-
