If diets worked, we'd all be thin by now.
So why do smart, successful people continue to struggle with weight loss?
In this episode of the Fit Over 50 Life Podcast, Mark Patrick and Kelli Calabrese sit down with Lizzie Merritt, certified weight loss coach, former middle school science teacher, bestselling author of LIGHT: The New Psychology of Weight Loss, and an expert in helping women over 40 lose weight without dieting, willpower, guilt, or starting over every Monday.
Lizzie shares her own journey from frustration and emotional eating to discovering a completely different approach to lasting weight loss—one rooted in neuroscience, behavior change, self-compassion, and understanding how the brain actually works.
This conversation goes far beyond calories, diets, and exercise.
It explores the hidden psychological drivers behind overeating, emotional eating, self-sabotage, people-pleasing, perfectionism, shame, unresolved trauma, fear of success, and why so many people know exactly what to do but still struggle to do it.
If you've ever said:
"I know what to do... I just can't seem to stick with it."
This episode is for you.
In this episode, we cover:
• Why diets continue to fail so many people
• The real reason knowing what to do isn't enough
• How shame fuels the weight loss cycle
• The connection between perfectionism and self-sabotage
• Why people-pleasing can make weight loss harder
• Fear of success and how it secretly holds people back
• The role unresolved trauma can play in weight gain
• Why emotional eating is often a coping mechanism not a willpower problem
• How stress and the nervous system influence food choices
• The science behind behavior change
• Why self-compassion is more effective than self-criticism
• How to stop starting over every Monday
• A practical framework for creating lasting change
One of the biggest takeaways?
You are not broken.
Your brain is doing exactly what it was designed to do.
Once you understand why you're eating, the weight loss journey becomes much simpler and far less painful.
