I have followed the diet plan for over 4 weeks now, and have only lost '1' lb. I am not much into diet drinks, so did not have too many of the Smoothies. Other than that, I followed the food suggestions as mentioned.The only thing positive I feel is the exercise program. I still continue to do the strength training 3 days a week, and then 3 days of either doing laps in the pool or 30 min. on my eliptical trainer.I feel that originally this book was written for men because it doesn't seem to address women other than pictures of women in the exercise section. I am over 50, so for some reason, the food suggestions/combinations is not working with my metabolism.
