Want to lose weight | 23M | 5'6 feet | 82kg

I have been hitting the gym for the past 15 days. I only do treadmill at the gym and reduce food consumption at home.

Excercise: about 1hr treadmill with 4.5kmph speed at 8 incline to reduce 400 calories per day

Diet: eat only twice a day instead of thrice. But I don't have much control over what I eat because I am living with parents. So my food is mostly rice, gravy and veggies.

In the past 15 days I have reduced my weight from 83kg to 81.5kg. I want to hit 79kg before new year.

Am I going in the right direction?
