I bought the book and cookbook to lose 10 - 15 pounds. I lost 8 pounds in the first 5 days and have managed to keep it off since I purchased the books 4 weeks ago. I priced these books elsewhere and found that they were a GREAT bargain. The cookbook was filled with a variety of recipes that are very easy to make and taste even better. I've also found that by substituting some ingredients I can easily cater to my preferences. I found that purchasing the 30 minute recipe book and the South Beach Diet book together allowed me to understand better what foods are acceptable to my new lifestyle. Today I feel healthier and I see that over time I'll be able to reach my weight loss goal.
