Great book to get a scientific overview of the basis of moods and how moods influence behavior, especially in regards to eating and exercise. It does contain some self-help advice, but most of the book is about distilling knowledge based on scientific research. The assumption is that this knowledge will help people become AWARE of their moods and how they affect their behavior, and that this awareness in turn is the best basis for regulating oneself (in this case regarding especially eating and exercise). The only reason I didn't give it 5 stars is on style, because in certain parts of the book the author can be a tad repetitive.
