I wanna be a health buff

I feel so desperate to lose my weight. I know that I could run and shed away my extra pounds but the thing is my schedule would not allow me to do so. The holiday season is coming and feasting on unhealthy treats would result in additional kilos in my body. My constant flight on foot from the hospital basement to the fourth floor would not be sufficient to burn the fats I am foreseeing to gain. I am thinking of popping some diet pills but before I try that I will try my hardest to enrol to a gym so I would require to do some cardio workout.
