My belly is increasing in size. i work as software engineer. sit 7-8 hrs a day in front of computer. how shall i reduce belly? i eat normal diet.

First of all: as a software PRO you should know there are programs and work stations which will encourage you to GET UP AND MOVE and not spend your time SITTING! Secondly belly fat may be a "genetic" issue(Insulin Resistance Type II Diabetes etc and a talk with your PCP (Primary Care Provider) may be useful Hope this is helpful NB Both FITBIT and APPLEWATCH have built in programs to help you!
