No pain, no gain..right?

I was teasing my office mate a while ago because after our lunch we went to Healthy Options. She said she will look for green tea capsules. She really wants to get rid of her excess weight (I won’t say “fats” coz she might read this post, hahaha!) But alas, we found none. I told her since she’s so lazy to go to the gym and shed some sweat, she may want to try the best and quick solution: diet pills! She really wants to return to her pre-pregnancy weight, but she don't want to feel tired and exhausted with exercise. Any suggestion?
