I feel you can have good diet plan made by dietitian and follow it .It should be reducing diet of around 1200 to 1500 cals. with lots of fibre. You can have good calorie-burning exercise like running,swimming or cycling 45 mins./day 5 days in a week.You should do strength exercise like springs,dumbbells or weights two days in a week. You have to follow this diet-exercise plan very patiently for not less than 6 months because these measures are only effective and scientific means to lose weight. You can take drugs when these measures fail. Gluformin may work if you have insulin resistance proved by increased insulin levels. There are other drugs like orlistat tabs and lately Liraglutide Injs high dose which can be taken under medical supervison.
