This book, what I call a guide or maybe you'd call it a diary, is separated into four chapters. One chapter equates to a week covering nearly one month-28 days to be precise, but it's not intended to be step-by-step or chronological. I decided on four chapters despite the '28 Days' title because my eating habits described within this book are quite boring and 28 separate chapters, while convenient for fleshing out pages, appeared a bit silly to me...
