whaaat !!! 110kgs, that was so a lot. Anyway prolonged sitting brings weight gains because the body is inactive so it does not burn any calories henceforth all the fat is retained inside. I'm happy that you are doing something to reduce the weight though it is advisable to take a 30 minutes break from your desk every after 3 hours of sitting because exercising at the end of the day does not counteract the impacts caused by sedentary living. By the way, Are you kenyan?
