I have a similar story.

During the holiday season around the new year I was at my heaviest: 245.

By May I had managed to eat better enough to get down to 232, but I seemed to hit a wall. At this time my wife took a job in NYC that has her out of town during the week and home on the weekends so I decided to try modifying the South Beach diet we had tried (and got good results with) a year ago. For me though, the problem was finding things I really wanted to eat (as opposed to "have to eat") in order to stay on the diet.

I stumbled upon something that worked for me not long after, I recently found out I was actually doing the Keto diet all along but did not know it.

One good thing about me is that if I like something I can eat it every day for a month with no issues.

Here's my weekday diet:
6:30-7am(ish) - Breakfast consists of two eggs (sometimes three) sunnyside up and coffee with Splenda and sugar-free creamer.

10am(ish) - A mid-morning snack: one fat-free Frigo Cheese Heads cheese stick.

11:30am(ish) - Lunch is a diet A&W Root Beer along with a Healthy Choice Simply Steamers meal (usually the Three Cheese Tortellini to feed my Italian DNA ;) ).

2pm(ish) - A mid-afternoon snack: one small bag of Planters NUT-rition mixed nuts.

6pm(ish) - A couple of hamburger patties (I usually grill these up over the weekend. I treat them more as an evening snack than an actual meal).

This is with sitting at my desk job most of the day then being on the computer most of every week night before bed (ie: a VERY sedentary lifestyle).

After a quick loss of weight the first week I saw a more gradual decrease of around a pound every couple of days. I also drink around 2-3 bottles of water each day (at least one with each snack to help fill me up)

On the weekends I cheat somewhat (the extent varies) and although it slows my overall weight loss down, the diet itself has helped curb how much I need to eat before feeling full to the point where a good meal around 1pm or so may do me for the rest of the day.

When I started this in May I was 232, today I am bouncing around 214-215. My immediate goal was 219 (how much I weighed when my wife and I got married 4 years ago), my intermediate goal is 210 and my long-term goal is sub-200.
