Weight Loss 100 Pound In Six Month 

Jessica Simpson took to Instagram Tuesday to announce that she's lost 100 pounds in six months, after giving birth to her daughter Birdie Mae in March. The 39-year-old former pop star (and current businesswoman) shared the news along with two photos of herself in a black dress cinched at the waist with a belt. One of the images shows her holding her holding her Birdie Mae. "6 months. 100 pounds down (Yes, I tipped the scales at 240 :stuck_out_tongue_winking_eye:)," Jessica wrote in the caption. "My first trip away from #BIRDIEMAE and emotional for many reasons, but so proud to feel like myself again. Even when it felt impossible, I chose to work harder. :green_heart:" Clearly, dropping 100 pounds in six months sounds pretty remarkable—and Jessica's followers chimed in to ask what exactly she did to lose the weight (seriously–most of the comments are asking her how she did it). Jessica didn't divulge how she lost the weight (or at what rate), but it begs the question: Is it healthy to lose that much weight in such a short amount of time?
