Cindy! I just wanted to chime in here. I have never done Atkins, but I know a lot of people who have. My dad, my stepdad, my husband's best friend, and one of my great friend's did. They all lost a lot of weight on it. They all experienced a drop in their energy level, though I don't know for quite how long. I know that my GF suffered with constipation. I don't know anyone who hasn't gained all of their weight back after they finished the diet and looked exactly as they did months earlier. My step dad has been on the diet for a few years now and we all pretty much expect him to go into renal failure anytime soon now (I hear he some some stinky urirne from all the protein he has consistently consumed over the past couple of years). I hate the Atkins diet. It cuts out antioxidents, tons of vitamins and minerals (supplementing with vitamins is not the same!), and necessary fiber, not to mention a great number of healthy foods that taste wonderful!
Do you do fitday.com? You can track all of your calories, where they are coming from, are you getting the nutrients you need?, and wether you are getting enough (a lot of people don't get enough so they can't lose weight!). I love this site!
I really don't like any diet of anykind as they only offer temporary solutions. It is really just a lifestyle change that makes a difference. I know how frustrating it is when you can't lose weight (I have had three kids!) but hang in their and make healthier choices and feed your body what it needs. It will respond in kind! Even if you don't get the perfect body, you will be rewarded with great health and a thinner if you if you treat it right.
Good luck!
