I'm one of the authors of "The Spark Solution," and I'm happy to answer your questions.
The book is NOTHING like any of the books you mentioned--it is uniquely SparkPeople. We don't have three "stages" but do focus on boosting metabolism, creating momentum, and inspiring motivation. I should also point out that though we used the word "diet" on the cover, this is a two-week plan designed to build healthy habits you'll continue for life. Unlike other plans, which you abandon when you reach your goal weight (leading to yo-yo dieting), "The Spark Solution"--just like SparkPeople.com--is designed to stick with you for life, leading to lasting weight loss and life-long healthy habits!
There are 70 recipes and a 2-week 1,500 calorie meal plan. The workouts can be customized. The strength moves are not all suitable for someone in a wheelchair, but the cardio workouts are your choice. If you do decide to purchase the book, I can share with you all of Coach Nicole's seated workout routines so you could swap those in.
Even without being able to do the strength workouts, I think you would still find the book useful. Let me know if you have any other questions!
"Maybe chance is a pretty common thing after all. Those kinds of coincidences are happening all around us, all the time, but most of them don't catch our attention and we just let them go by. It's like
fireworks in the daytime. You might hear a faint sound, but even if you look up at the sky you can't see a thing."
