I lost almost 90 lbs and have kept it off for over 2 years following Dr. Atkins plan. The beauty of this is, even though my scale weight has remained constant I have continued to lose inches.

For me, lunch is often the hard part. If there is no leftovers (which I try to make sure there are, but sometimes my boys are extra hungry!), then I make deli ham or turkey spread with whipped cream cheese and toss in a pickle spear and roll it up. I went thru a whole freekin' jar of pickles last week and now I'm a bit green when I look at them! That will pass...its just so dang easy! Also, the deli up the street from my office makes a chicken salad with blue cheese dressing instead of mayo and adds hazelnuts and celery - oh lordy that sutff is beyond compare. And just a little bit satisfies you cuz its so rich. I'm going to try to make that at home as soon as I buy some really good blue cheese dressing. You can't really use the regular bottled stuff. It has to be super thick and creamy.

Good luck expanding your food list!

and since I live alone I can eat whatever I please:
so:I tend to eat a lot of steak, bacon, chicken, hamburg

and I grill a whole bunch at a time, freeze or store in plastic bags..........then microwave to reheat when I want to eat.
I also eat salad almost ev ery day.......or right now I am into frozen broccoli florets from SAM's which I cook 13 oz. at a time (just happens to be what fits the saucepan I leave on the stove every day) with 2 TBSP of Butter and 3 TBSP parmesan cheese and lots of fresh ground pepper. I am sure I will get sick of this but right now I love it and have it almost every day. It is filling and low carb and low calories.
For awhile, I did a Karen's crustless cheesecake and ate some every day for a couple of months or so..........but eventually tired of it.
I also do Quiche Lorraine, 4-egg cheddar cheese omelets,
pickled hard boiled eggs, lots and lots of cheese (mostly Cabots); some Carb Smart ice cream once in a blue moon, black olives, stir fry chinese cabbage, lots of cold cuts like roast beef, genoa salami, hard salami, pastrami, swiss cheese.
