Gwyneth Paltrow wants you to cleanse! The star has just completed a three-week detox program while she's filming Iron Man 2. "I feel pure and happy and much lighter. I dropped the extra pounds that I had gained during a majorly fun and delicious 'relax and enjoy life phase,'" Paltrow writes in her newsletter for her website Goop. The special program, conceived by Dr. Alejandro Junger, requires her to consume one solid meal with no processed foods, dairy, or sugar and two liquid meals each day. (Photo: WENN)
