Has anyone tried a liquid diet after giving birth? I gained quite a lot of weight dieting my pregnancy and I have 4 weeks left. My doctor says she only wants me to gain no more than 2 to 3 more pounds. So I got rid of carbs and sugar and lost 2 pounds. Since I won't be able to do anything but light exercise for over 6weeks I was wondering if a liquid diet has worked for anyone after giving birth?
