Given the task definition and input, reply with output. In this task, you're given reviews from Amazon's products. Your task is to generate the Summary of the review.

The book did a pretty good job of explaining the diet, but there were no online calculators to accompany the book to figure out how many calories, fats, carbs, protein, you need. It just had formulas. Also, this is not really a book to get you started on the diet; it's more like background information.. The recipes in the book are few and the 28 day meal plan has no accompanying recipes!
Disappointing: No calculators, no recipes to accompany the diet plan!
