Weightloss

Everybody is giving u the right advice but what's sustainable for you that you should decide. It's not hard but you need certain fundamentals to understand. I would advise you to watch hypertroph channel's fat loss series to get the fundamentals then decide on the approach. Loosing 20kg can be done in a year.

You cant control what you cant measure

just start tracking calories with any of apps ( i use loseit, or healthifyme).

Try to keep it below 2k for a start, eventually youll find your way around it.

Measure weight alternate day, same philosophy

To start with, pick out healthier options to eat and maintain atleast 13 hour gap between dinner and breakfast.
This should drop 3-5 kg in the first 4 weeks.

@TidyGeneral7 brother, don't be so hard on urself. Try to cut the sugar like reduce coffee tea juice cool drink consumption. Walk regularly morning and evening. Whenever u r on call just walk and talk. Try to do stretches.. Eat healthy food, avoid outside food. Try to replace calorie foods with raw fruits, sprouts, boiled veggies.. Drink luke warm water with honey, in empty stomach in morning. These r simple yet effective. I tried this and it worked well for me..
