hi anusha.u just need to concentrate on mainly two things workout n nutrition. eat clean, small meals at regular intervals. do weight training followed by cardio (hiit) .lack of details in ur question so its hard to customize d workout plan/diet plan. so keep it simple. if ur nutrition is good then u dnt need supplements. if u want to fill d gaps of ur nutrition u can try supplements like pure whey isolate. n for fat burning u cn try green tea+honey+cinnamon+warm water or u can try supps like carnitine+fish oil+cla+rasperry ketones or a stimulant fat burner like hydroxycut,lipo6 hers etc. stay motivated eat clean n dnt forget to lift the weights

Have you heard or tried of HIIT traning?

It burns max calories in a limited amount of time, have a look at this program where in all workouts rest times evertyhing is all done and ready for u and the best part is you van do the workouts from anywhere
