Hi Thank you for posting your query.I have gone through your question and according to my view weight gain and weight loss depend upon BMR ( basal metabolic rate ).So I will suggest you to keep your metabolism good by eating proper balanced diet and doing proper exercise and yoga regularly.Here I m giving you proper diet which you can follow to reduce weight - Have a low calorie diet like eating green vegetables,veg soup,green salad,citrus fruits,fruit juices. Limit the consumption of rice,potato,sugar,mango,litchi,bananas,grapes. Limit the consumption of dairy products in your diet like cheese,ghee,butter,paneer. Drink 1 tbsp honey with 1 tbsp lemon in a glass of water. Take 30 ml of aloe vera juice empty stomach everyday. Have 1 tbsp trikatu and 1 tbsp triphla churn with lukewarm water.. Here are few asanas or exercises which you can follow for reducing weight Suryanamaskar ,pavanmuktasan,naukasan,bhujangasan,ushtrasan,dhanurasan,kapalbhati pranayam. Go for a walk everyday morning and evening. I would highly recommend a panchkarma therapy udvartan in which medicated herbs in powder form are rubbed all over the body.It helps in reducing 5-10 kg weight in 10-15 sittings. Hope this answer is useful to you. Best wishes for your health! Regards Dr.Pallavi
