Sorry, dear, but the only way you can possibly permanantly lose any weight is through the most obvious way: decrease the calories, up with the exercise. Is it a pain in the ass? Yes. But it will benefit you the most.
I have lost around 25 pounds since arond march, but the only reason why it's been so slow is because I have a tendency to cheat (working on it! :?)
i try my best to limit my calories to 1,200-1,300 a day, I eat lots of fruit and veggies, and try to avoid junk. I eat loads of fish and chicken, too. I also do an hour on the treadmill 5-7 days a week, plus yoga, crunches, and a bunch of other stuff. Oh, and definitely avoid drinking alcoholic drinks more than once a week. On weeks when dad brings home dark amber cider, I bloat up so fast it's hilarious, even when I stay within my 1,200 cal. Range. Weigh yourself every day in the morning. It's the most concrete way of tracking progress (obviously, there will be days when you are bloated or have water weight a week before or during your cycle, but you should know yourself if it's because you are about to have the painters in, or if it's you ate one french fry to many--be honest with yourself.). Definitely buy a small food scale, and go on nutritiondata.Com to find the caloric value of your food. Because you are already so overweight (absolutely no offense meant there!!!), it won't be so quick that you begin dropping clothing sizes, even afte 15 pounsds or so, but ass you lose more weight, the difference will increase, and you'll see more dramatic results, but your clothes will be looser, you'll look trimmer, and you'll have much more energy. I only dropped one clothing size, but I got rid of my high blood pressure. Best of luck to you and your baby!!!
