Hi dear Check with the physician that do you have any hormonal issues or all are fine. If all are OK, then do follow the right steps towards weight loss. Concentrate on the exercises mostly cardio, particular areas which are heavy, try to work out on those. Have small n frequent meals throughout the day. Avoid carbs n sweets. Keep yourself hydrated. Drink green tea once daily. N also consult a dietician for detailed personalized consultation.
