Yes, yes, yes, and I say again, YES! This is so very true. This is a subject near and dear to my heart--I am a fitness fanatic who never had a weight problem until I had babies. I successfully lost the weight after #1, and am still losing after having #2 9 months ago--only 5 lbs left to go!!
Anyway, my point is that it's true--there is no quick fix or easy way, but then you knew that already, of course! It's HARD work losing weight. If it weren't, there wouldn't be so many overweight people in the world. You're doing great. One thing I noticed after both my babies, is that no matter what I did, it seemed the weight just would not come off in earnest until I was at least 6 months post partum. Something about that timeframe made a big difference in the amount of effort I had to put forth in order to see results. I don't know if it's hormones or just being exhausted, but once I made it past the 6 month mark, the weight seemed to come off much quicker and easier than before that.
I used Weight Watchers (still using as I'm still losing from second baby) both times. It works great for me. I used the online program the first time around, no meetings--not my cuppa tea. Now I know the program and don't even have to use the online features, I just track my points myself. Anyway I find it to be a very convenient way of eating--no calorie counting, and nothing's really off limits, although you quickly learn to eat high fiber, low fat foods because you can eat MORE of them than any other type of food.
Anyway--hang in there. Post partum is an especially tough time to lose weight, I believe, because you're dealing with hormones and exhaustion and just being a mommy to a young baby! That makes everything more difficult. Keep plugging away, and you'll get there. And remember that losing weight slowly really is more effective for long-term weight loss. You want it to be fat that you lose, not just water, and definitely not muscle!
Oh yeah--and EXERCISE!! It's so important. Not just cardio, either. Weight lifting will build lean muscle mass, and muscles burn more calories at rest than fat and other body tissue. You don't have to look like a bodybuilder to get the benefits from it. As far as cardio, even if it's only 20 minutes, 3 times a week, DO IT. It'll make such a difference in your energy levels, and it helps SO much when trying to lose weight. I think trying to lose weight through diet alone is really, really difficult. Add in a little exercise and it increases your results dramatically. Plus it just makes me feel so much better, personally.
Good luck, and hang in there. Try not to be too hard on yourself--it's tough enough being a new mom as it is.
