Losing weight is not an impossible task and could be done with patience,resisting temptation and dedication. Let me make you clear.
1)Say no to foods containing fats and sugars( Ice cream,sweets, cheese ,butter)

1. Start doing a cardio session( Running or dance)
   3)Join a gym or go with home workouts, take enough amount of proteins so that you could make a muscle.
   4)Have proper sleep, not heavy but adequate (6-8 hrs)
