there is no fastest method of loosing weight. Looking at your height ideal body weight is 60 kg. Bmi is 26.97kg/m2, best way to reduce weight is to plan a loss of 2 kg per month, can be done by cutting 550 calories per day from existing intake, exercising regularly so that extra caloreis are burnt, which help in reducing about 1/2 kg per week. This approach will be better than any drastic reduction. If you want me to guide then come in a private conversation with the details like - fasting and pp sugar
levels, hba1c%, medications being taken, level of physical activity and dietary pattern. The exercises that are to be planned should suit your age and capabilities. I am not sure if you are a person who has been exercising regularly earlier.
