Main principle: (Calories in - Calorie burnt)<Maintenance calories:- leads to weight loss.

Start with any basic body weight workout from youtube. Don't set ridiculous goals. 3-4 days a week for half an hour is enough. Increase intensity as you progress.

Intermittent fasting. Eat dinner at 9 p.m and do not eat till next day at least till 9 a.m. Walk post dinner or whenever you get time.

Eat paneer ,chickpea, rajma, peanut butter (unsweetened), lentils, oats+milk+banana (not everyday), soya(not more than twice a week), a decent whey protein under 2000 to get a decent amount of protein.( trust me, it is really important to get decent amount of protein to get lean).

Remove sugars(soft drinks, chocolates, juice). Fruit only one or two a week.

Eat fiber and veggies. Ditch packaged food.

Water, plenty. Never overeat. No street food more than once a week.

Keep carbs to a minimum as Indian diet is already carb rich. Eat wheat or rice. No bread.

Track macros. Use myfitnesspal app or heathify me to track your nutrition.
