To reply to your desire/concern for low sodium--Do NOT use regular iodized salt. Buy sea salt or kosher salt, and you will know the difference. You will be surprised to see the difference in the amounts of sodium per serving between the two. Also, with sea/kosher salt, you don't use as much because it has a naturally very organically salty flavor, if that makes sense. Do a taste test of your own. You'll find that you could actually be cutting your sodium intake in half, and actually getting a healthier version of the sodium that your body needs. (It's not just about cutting the bad stuff; it's also about replacing it with good stuff.) You don't always taste the salt, but it's in everything because of its chemical benefits with how it helps food to cook a certain way and how it preserves, etc. Read the instructions for cooking oatmeal. They tell you to add salt to the water! There is no healthy way around taking control of what you consume. The reason that we are in the bad shape that we're in is that we are looking for shortcuts--prepared/processed foods, ways to cook food faster, etc.--all of these unnatural ways of eating. If you really want to be successful, you will have to figure out how to slow it down. You will need to commit to a way of life that will include eating more naturally, natural ingredients that your body can process instead of the packaged and processed stuff. It's not necessarily about the recipes as much as it's about the ingredients. You can eat lasagna everyday if you use fresh ingredients with no junk in it...and if your body can process everything. (I can't eat the pasta. My grandmother can't eat the tomato or spinach. Some bodies don't process the cheeses.) I cannot stress enough that all diets are NOT the same and do not work the same for everyone because all bodies are not the same. Apples are an awesome food to consume, but if you are allergic, they can be deadly for you. At the very least, they would break down your body's ability to process foods, thus compromising your entire digestive system.
One thing that works for me is to keep carrots and cucumbers and sunflower seeds, etc. around. I basically sit at a desk all day and am a grazer, so I keep around the things that I know won't hurt me. Instead of grabbing a bag of potato chips, I go to the refrigerator and grab some pineapple chunks, from a pineapple that I cut open myself, not a can. Maybe you don't like carrots. Find something healthy for your body that you can enjoy, and keep it around. I opt to park in a place that forces me to walk a little to my office, including one flight of stairs. (Contrary to what someone else might say, exercise IS extremely important. You don't have to run a marathon or even go the gym, but you have to move around to keep things moving in your body. Without proper circulation, things literally get sluggish--organ function, blood flow, bowels.... There is no way around it, if you're looking to be healthy. If you're just looking to lose weight, then you can just lie down and drink water all day. You'll be weak and have no muscle tone...but you'll be thin--yea! That's not what you want, and it's not what you want to teach your little girl.

I think that you won't be successful in losing and maintaining unless you know why you are overweight in the first place. Never mind the psychological effects of certain foods, certain types of foods and activities affect our bodies differently, and you'll only be discouraged to fail at what works so well for someone else.
For one, stay off the scale. I am not really overweight, but my breasts are so friggin' heavy that I feel fat when I get on the scale. That was the case even when I was pretty thin (I have a small frame.), and I KNEW that I was no where near fat. Also, muscle is heavier than fat, so the more muscle you build, the heavier you might be...and if you start losing weight, you'll think that's good, but you could actually be losing muscle, which is bad.
Until I figured out that I have a gluten intolerance, I never understood why my always "healthy" diet still left me bloated and constipated and so tired, too tired to exercise, which made me feel depressed and sorry for myself because I wasn't being active. All I did was cut the gluten for two weeks, and I noticed a HUGE difference! I felt the depression lifted within a day or so--seriously--and I had a bit of energy. Depression is actually one of the symptoms of my condition. My bloat went down, and I began to see definition again.
I'm a person who grew up with a taste for fruits and vegetables and no love for cookies and cakes, etc. I like wheat germ and oatmeal, and my occasional piece of bread was always some whole wheat something or other. I couldn't understand why I just suddenly "blew up" and couldn't go back down. It turns out that those things are THE WORST things that I could consume. I'd have done better to eat candy for days than to eat that stuff. It's all just a matter of what's good and not so good for YOUR body. In order to be successful, you'll need to be willing to become a student of your body, no shortcuts. For now, you might wear a cincher so you can feel good in your clothes, to motivate you. It'll be rewarding, though, to learn what you learn and know that you can do it on a permanent basis and BE HEALTHY!
