Cycling, jogging, swimming walking for at least 30 min 5 times weekIy at gym or home you can start with -stretching exercises.
Please make sure you dont increase your food intake in mean time.
2. Drink more glasses of water,when you are thirsty please do not take any other fluids as a substitute like juice, coke, etc .
Take green tea twice daily that burns fat and keep you active.
Eat lot of fruits and vegetables, this will not only reduce hunger but also add to the bulk of the food.
Skimmed dairy products, take fresh salad after lunch and dinner like cucumber, tomatoes with curd.
