Hi welcome - hi you can make slim body but slowly consistently. First stop taking all fried foods, junk, cream based foods. No butter, ghee, dalda, no oily too much parotha, puri foods. Very less rice. Go for high fibre based diet, whole grains, multi grains flour, take plain roti, phulka, vegetables low in potatoes, more gourd s like bitter, bottle, snake gourd etc. Do not consume nuts group, coconut, banana, mango. Sleep only at night 7 hrs. Most importantly you be dynamic, more working not sitting one place but outdoor at pollution free zone. Diet & exercises can help you best. Keep on regular but more exercises needed two times, mainly early morning max. Jogging, brisk walking & normal running must may be full of sweating. So consume more water & electrolytes. Diet must be balanced based on low calorie all foods. Remember without exercises & well planned diet both clubbed can help you here.
Reduce intake of cereals, maida products, sweets. Keep yourself hydrated. Have lots of fresh veggies n fruits. Keep small gaps in between meals. Do exercise daily for 40min for atleast 5/6 days a week.
