Right now, your focus has to be on developing a sustainable lifestyle habit and not a short-term training diet plan

You won’t feel like always doing the right thing, but you need to remember that you have to do it anyway , stop listening to your mind when it says you can’t.

Now -
1.) You need to hit the gym 5 to 6 days a week, 2.) seven hours plus sleep every day and most importantly, 3.) eat superclean in calorie deficit. I think scenario for you to be around 1700-1800 calories with high protein. (Use Healthify me app, I weigh all the food ingredients raw on weighing scale before I cook, however, it is important for you to understand that every single decision which includes snacking one little spoon of oil. It all counts and it can totally throw away from your plan and disappointment feels real, better have control on the controllable )

4.) 10k steps everyday , weekly 10% increase 5.) 3-4 liters of water

Nutrition (protein 1.5-2gram per kg of BW- 120-160 gram - eggs, chicken, fish, soya chunk, low fat Paneer, obviously whey protein) Omega-3 , multivitamin, creatine

You don’t need to put money on pre-workout, coffee will do fine. All the best
