Melanie, first of all, congratulations on sticking with the no sugar.no flour part. That is a big hurdle to get over, and you should feel very good about what you're doing. My question to you would be, what else are you eating? Slow weight loss can be caused by too much food, but also, surprisingly, by too little food. Your body needs a certain amount of food every day to sort of stoke the furnace of your metabolism, and to make sure it doesn't think you're starving yourself, which can cause your metabolism to slow WAY down, trying to conserve every bit of energy it can in case there's a food shortage.
I have honestly seen a person losing weight really, really slowly (in fact in a complete plateau for 6 months), who started dropping pounds again when she had more food added. Are you using a program or trying to do it on your own? Certainly if you're in a 12-step and have a sponsor, that's the person you should be working with to tweak your food plan (and your doctor, of course). If you're doing it on your own, you can try a site like fitclick.com (I have no affiliation with the site; just find it's one of the easiest to use for tracking daily nutrition). See how many calories you're getting, and what the site recommends you need to be eating to achieve your goal. There are other sites that can also help you choose a realistic goal weight and give you some numbers in terms of how many calories it will take to maintain at that goal, and how many calories you need to be eating now in order to lose the weight. Please don't make the mistake of thinking the less you eat the faster you will get there. It really is a "tortoise and hare" situation, where slow and steady wins the race. But it isn't a race, either - please try to get your mind around that. If you're going to succeed and keep the weight off, you absolutely need to change the way you eat and your relationship with food FOREVER!!! So really, what difference does it make if you get to goal in 3 months, 6 months, a year? The only thing that will change is that you'll be able to start building a wardrobe of clothes that will fit you every time you put them on.
You can do it!!! But please do it wisely.
