Frankly speaking there is no medicine to reduce belly fats. Sitting continuously for long hrs is a major cause of this problem. However some stretching may even be done while sitting on chair as well as walk inside your office room off and on whenever possible. Your diet protocol is very important. Taking high roughage diet and low caloric food will help you. Also deep breathing for at least 10 minutes daily to start with and fresh air walk for 30 minute at a stretch is useful. Some medicine which evacuate the bowels properly and help regulating the itch for repeated eating will control your longing for extra food, junk etc. Hot water boiled with some daily use herbs such as ginger, pepper etc. if drunk daily also sheds some fats. Similarly purest asafoetida, mixed with Ajwain seeds and black salt, if taken with such hot water, will further reduce little fats. In any case fats on belly comes the first, goes the last. If you agree, pl consult through direct question for further guidance and treatment plan with more such safe herbomineral formulae such as Medohar guggul, Arogyavardhini vati, Pathyadi Kwath etc Hope you will understand but never, ever, go for hormonal or toxic wt shedders pl.
