Weight loss seems to be a tricky thing. Cutting out starches and sugars will definitely make a difference in terms of the health benefits, but how much weight you will lose is pretty unpredictable.
I started an Atkins-like diet last June and lost 56 pounds by November. Then the loss stalled, but I was able to maintain my weight until mid- March. Since then, I am back on Induction, but I have only lost 1 pound in 12 days. However, I am now at the upper end of what could be considered a "normal" weight for my height and age.
The reason a second (or third, or forth) run at the same weight-loss protocol may not work as well as the first for several reasons:
The first time around, you didn't know what to expect, and the weight loss came as a nice surprise. The second time around, you have certain expectations about how things should unfold. When the weight does not come off as quickly as you remember from the first round, you may doubt the protocol or get frustrated and throw in the towel.
Also during Round 1, you learned how far you could push the boundaries of your weight-loss protocol. All those small allowances that crept in later in the cycle may now become part of the protocol right from the start, creating different conditions than last time that could lead to different results, as well.
If you happened to lose muscle during your previous weight-loss attempts, any subsequent attempts will be more difficult, since you now have a lower basal metabolism (the number of calories you burn at rest).
The same is true if you didn't lose muscle but lost a lot of weight and maintained that loss. Your body now doesn't need to work so hard to move your body from here to there, hence you need fewer calories for everyday tasks
If you have gone through many weight-loss cycles, your body may have become very savvy at functioning on a small calorie budget, and creating a further calorie deficit may be difficult.
Finally, your health status may not be the same now than it was then. If you are on new medications or suffer from new health problems, those may prevent weight loss, or even result in weight gain.
You'll never know until you try, though. I would give it a serious effort for about a month. If nothing budges, it's time to investigate what could be wrong. Consider this an experiment. You'll only get correct results if you stick to your chosen protocol for a good length of time.
Don't throw in the towel too soon, just because the scale doesn't want to cooperate. Maybe you'll be losing inches, rather than weight, and that would be an indication of progress, too !
Highest weight ever: 220 pounds
Followed the IP protocol with slight modifications from June to December 2012 and lost 58 pounds.
In Maintenance mode from December to July. Didn't re-introduce any of the carbs recommended by IP for Phase 4 and Maintenance. Increased fat intake and was able to maintain my weight.
Back on Phase 1 of IP to get to 140 pounds. Hitting some snags, though.
