Dr. Walford explains the basic theory of Calorie Restriction and gives some practical advice on how to implement it. In this respect, the book was exactly what I had hoped for: less theory and more practice.
I was also excited about the recipes, but they seem rather intricate and daunting. I'm a reasonably able cook and I think I could manage OK, but my pantry lacks many of the ingredients required. To cook any one of the primary meals listed, I would need to find a half dozen ingredients that I've never purchased before. I don't enjoy shopping much, so finding and buying all those things seems like a big hassle. I'm sure the recipes taste delicious and prove that Calorie Restriction doesn't need to me asceticism, but it's hard to get started when there are no simple recipes to ease its adoption.
Also, I don't think my wife would appreciate me cooking and storing about 50 meals in our freezer as the author suggests. There's hardly any room in there as it is.
All that said, I'll give some of the recipes a go, but I can see myself simplifying them.
