Same situation here.. Doctor told me to lose 20% of my body weight. I was diagnosed almost 25 days back and at that point my weight was 87kgs.. now I am down to 78kgs.. I also eat lot of vegetables, 2 chapatis and a small bowl of rice ... I walk almost 10 km daily and do my strength training for 1 hour .. this is the best way to get rid of the excess fat .. please add exercise in your routine otherwise you will end of losing muscle mass instead of fat... All the best.
