The Natural Diet - by Andres Digenio (Paperback)

About the Book

The Natural Diet is a science-based, easy-to-follow approach to weight loss and healthy living that helps people break free from ultra-processed foods, which now make up 50% of the American diet and are the leading cause of obesity and metabolic disease. Unlike restrictive diets that eliminate entire food groups, The Natural Diet takes a balanced approach, using history and science to guide readers toward sustainable, real-world eating habits--without cutting out dairy, grains, or even the occasional treat.

Designed for individuals, couples, and families, this 24-week flexible action plan blends nutrition, exercise, and behavioral strategies to create lasting change. Readers will learn how to differentiate between processed and ultra-processed foods, improve food choices, increase physical activity, and build healthier habits--all without counting calories or feeling deprived.

At the heart of the book is Brenda's story, a busy professional in her 40s recently diagnosed with diabetes and at risk for heart disease. Unsure of how to make meaningful changes, she joins a web-based lifestyle program with coaching support. Through small, realistic adjustments, she learns how to eat smarter, incorporate movement into her daily routine, set achievable goals, and overcome obstacles. Over 24 weeks, Brenda loses 7% of her body weight, improves her diabetes, and adopts lifelong habits that benefit both her and her family.

With scientifically-backed guidance, real-life case studies, and an accessible, practical approach, The Natural Diet is a refreshing alternative to fad diets--helping readers lose weight, stay active, and reclaim their health for good.
