Inklink, you are on the right track. Gradually cut the carbo. I eat 5 table spoon of rice per meal (3 meals a day). That is all the carbo I need. I consider my kung fu exercise vigourious (twice a week). The instructor is worst than a drill sargent it the military program. At the end of the session, even my undergarments are soak. In spite of that, I do not eat more to compensate for it. I gone from 85kg to 66.9 kg in 1.5 years. Very soon I will be in the right BMI (height 163cm).
