S. - I think the responder below who talked about starvation mode is right! Check your BMI, http://www.nhlbisupport.com/bmi/ , from what you poasted, you area at a healthy//normal weight for your height. Remember, your body went through alot to bring this baby into your life, and it will never be exactly the same as it was before baby, even if you do get down to the same weight, the changes are in hip width, and structure down there, and the C-Section ( I have had 2) will make it harder to not have a poochy thing. Also, your skin will take some time to tighten back up...make sure you are drinking enough water to help with elasticity.
Especially if you are nursing still, cutting your calories in half is going to throw your body into survival mode, it is conserving fat stores to make enough to feed the baby before losing it for you! Here is an article on La Leche Leage website about caloric intake for nursing:http://www.llli.org/llleaderweb/LV/LVOctNov97p115.html
Children's Hospital of Boston says this:
"sufficient caloric intake - Eat many different foods to get the calories, vitamins, and minerals you need to remain healthy. A minimal caloric intake of at least 2000 calories per day, with an optimal intake of 500 calories above a non-pregnant caloric intake of 1800 to 2200 calories is recommended. (This is the equivalent of a peanut butter sandwich and a glass of milk.) Foods from the following food categories offer the most nutritional value:
meats
beans
vegetables (especially leafy green vegetables)
fruits or 100 percent fruit juice (not fruit drinks)
breads, cereals, and grains
milk, cheese, and eggs "
Try to eat 5-6 mini-meals a day, with a combination of some protien, veggie and carb (fruit or whole grains) in each one, eating smaller portions, more often will stoke up your metabolism, and you will probably burn more than just 1-3 meals a day. It gives your body reassurance that more food will be coming ina few hours, so it doesn't think you are starving and hold on to everything!
I have also recently heard about dry brushing your body to tighten skin and improve appearance of cellulite - t encourages blood flow, lymphati flow, and exfoliates. That might be something you want to look into doing to help tighten things back up. Also, there is a great exercise system called T-Tapp tha is all about usin all your layers of muscle and forming an internal muscle "girdle" around you abdomen to achieve that flat stomach look again, you might look into that : http://www.t-tapp.com/
Good Luck!
