Lose Weight with the Help of AI

What if the one thing standing between you and lasting weight loss wasn’t willpower, but being able to do the maths?

For decades, Julie Creffield tried everything...marathons, CrossFit, endless diets, calorie counting, spreadsheets. As the founder of the global plus-size fitness movement Too Fat to Run, she inspired thousands of women to lace up their trainers and embrace fitness at every size. Yet despite running six marathons and training almost daily, she could never quite get the nutrition piece right.

In her forties, Julie was diagnosed with ADHD, and suddenly it all made sense. The relentless calculations, the decision fatigue, the inability to stick with complicated tracking systems… it wasn’t a lack of discipline. It wasn't a character flaw. It was a brain-based challenge that was totally fixable with a bit of emerging tech support.

So she turned to the one tool built for relentless pattern-spotting and always on solution support: Artificial Intelligence...Also known as AI.

Blending her 30 years of experience as an innovation and transformation expert with her proven Year to Change methodology, Julie built a custom GPT—a personal AI weight-loss coach—and set herself an impossible challenge: lose 100 lbs in a year. Eleven months later, she’d done it. And to prove that she wasn't an anomaly, she tested the process with more than 100 people and proved it works for as wide range of people.

This book isn’t another diet plan. It’s a system. A compassionate, flexible, AI-enabled approach that helps you:

• Break free from the “start again Monday” trap.

• Use AI to handle the maths of food, exercise, sleep, and energy tracking.

• Reset your macros as you lose weight, without overwhelm.

• Turn tiny daily actions into big, lasting change.

• Build momentum with binary tasks and compassionate accountability.

Whether you’ve failed at every diet under the sun, or you’re just curious about how technology can finally give you the edge, this book offers a bold, practical path forward.
