The Last 15: Say Goodbye to Those Most Stubborn Pounds

Nationally recognized health expert and #1 NY Times bestselling author Dr. Ian Smith releases a transformative 7-week program that helps men and women finally overcome the hardest weight to lose—those last 15 pounds—and keep it off for life. The “last 15 pounds” are where most Americans get stuck, and The Last 15finally explains why.

Dr. Ian breaks down how metabolism adapts, why quick fixes backfire, and how strategic nutrition phases turn plateaus into progress. While many diets chase temporary solutions with extreme strategies, The Last 15 focuses on natural, sustainable methods backed by the latest science. Each week introduces a targeted nutritional phase—from protein optimization and carb cycling to hydration, fiber, and sodium control—that helps readers retrain their metabolism and reshape their body as they finally shred those stubborn pounds that otherwise won’t go away.

“The last 15 pounds represent more than stubborn fat—they symbolize the body’s resistance to change,” says Dr. Ian. “Once you learn how to move through that resistance with strategy instead of struggle, everything about your metabolism and your mindset transforms.”

Backed by physiology, psychology, and real-world practicality, The Last 15 offers: A complete 7-week metabolic reset built for men and women of all ages Weekly meal plans with portion guides for men and women Science-driven principles: metabolic reset, carb cycling, micronutrient balance, hydration, and sodium optimization Over 50 simple, affordable, nutritious, and tasty recipes A Maintenance Blueprint that teaches readers how to stay lean for life As a bonus, the book includes over 50 recipes and over 50 snacks to make following the plan even easier and more affordable.
