Once a graceful ballet dancer, my cousin Michelle felt more like a blimp after gaining 50 pounds from her pregnancy. When calorie-counting plans left her with little energy to care for her son, Joaquin, she tried taking safe diet pills. Suddenly she was gliding through her days, taking good care of his son and has even added walking to her daily activity. A little more and she’ll go back to dancing again. I asked her if the pill had side effects, but she said she experienced none.
