Query: Some good info, but bus. plan metaphor is tiresome

This book contains good basics (e.g. calories in vs. calories out). It helps you calculate your calorie expenditure and figure out how much you can eat. The information seems sound. I have two main objections to the book. First, he spends a lot of time explaining business terminology and cramming dieting into a business model framework. If you have even a rudimentary knowledge of business terms, you quickly get tired of his long explanations. Second, his exercise routines seem designed primarily to drive sales of the exercise equipment he shows in the book. This is a good business plan for his wallet. I think the book would have been better if he had offered weight exercises that did not depend on his special equipment.
