Hey man, Hows it going? I think we are in the same boat, just I started in January. I have lost about 50 pounds now, and its all about getting a routine established that you can follow long term. Another thing I would suggest after reading through all your posts is this: You are eating enough calories to support organ function, and thats about it. Your body will be okay with that short term, but like someone else said, it will go into starvation mode eventually, and you will totally plateau/ put weight back on. In order to "trick" your body, have some variety in how many calories you eat. On a low cal day, do about 1800 cal, and then go as high as 2700 some days. The calories you eat need to full of nutrients. Your body has extra energy (stored fat) and you need to eat to give it nutrients and repair building blocks (protein) . This will give the muscle tissue and organs food and let your body burn its extra fat for energy. Then another thing is one meal every 2 weeks or so, go ahead and cheat a little. If you don't think you have the willpower to get right back into eating the right stuff, then don't cheat! Don't eat like 5000 calories or anything, but eat something you miss in moderation. It will let your body know that its not being starved, you're just training it.
One last thing. When I first started I was obsessed about the numbers on the scale, and weighed myself daily. Forget that. Scales make errors and your body changes from day to day. Since then, I have decided that weight training is important to my long term weight loss goals. The more muscle you build, the more fat your body burns all the time. When I was so obsessed about weight loss numbers, I would stay away from weights because i made my weight loss slow....little did I know that it was because my muscles were growing and inflamed with water weight. The point is don't worry so much about day to day weight as you do about building a better body that can burn that fat 24/7, and fueling that fat burning machine with good fuel.
