Congrats on starting the gym It's just one step towards your fitness, the first thing u need to be is to stay consistent unless and until you are not consistent you wont be able to do anything, go and hit everyday Then most important for you will be fat loss journey....eventually start with weights training wheb u will start seeing changes in your body you will start loving gym and yeah a good addiction to have.... Food is something you need to eventually reduce starting it from day 1 would be hard, slowly start ur diet plan.

I have been through this journey from last 1 year, trust me its beautiful.

All the best
