Query: Disappointed, but persevering

I just finished the 9-week program, which the authors wisely emphasize is just meant to get you started. I complied with the diet about 80 percent of the time, and the workouts about the same. I have gained a small but noticeable amount of muscle definition in my shoulders and arms, but I lost only about six or seven pounds ... roughly half of what I had expected based on the testimonials in the book. I'm pulling my belt in one more notch, but still wearing the same size pants, so I didn't lose the four or five inches their test subjects claim to have.The diet is easy enough to follow, and includes enough recipes to not be too monotonous, especially if you use the principles to find additional meals. But at this rate, it will take me a year to reach my goal weight, and I know I won't follow it that long unless I get some significant success much sooner than that.
