The book appears to have been written around the late 1930s to the late 1940s, a time when societal standards of beauty and health were evolving, particularly for women. The aim of the book is to provide practical advice for women seeking to either lose weight or gain it in a healthy manner. The book takes a conversational approach, addressing the emotional and psychological aspects of dieting while emphasizing the importance of proper nutrition. It presents the idea that both overweight and underweight individuals have challenges related to their respective body types. It encourages readers to consult medical professionals and to adopt a balanced diet rich in essential nutrients, such as proteins, vitamins, and minerals, while also providing sample menus and calorie guidelines. Ultimately, Abel seeks to demystify dieting and instill a sense of empowerment in readers, advocating for sustained, healthy choices rather than fad diets or quick fixes.
