Why I Created Fasting That Works
I'm Dr. John D'Ambrosio, a chiropractor with 33+ years of clinical practice, former personal trainer, and author of "Fasting That Works."
While fasting is naturally muscle-sparing, unlike traditional calorie restriction that destroys muscle, most people still aren't optimizing their results. They preserve muscle, but they're not building it.
I created this method to help you do both: a strategic approach that combines intermittent fasting with intelligent strength training protocols, so you burn fat while actually gaining muscle and strength.
My Approach
Science-backed. Sustainable. Results-driven.
After 33 years as a chiropractor and decades training clients, I've watched every diet fad come and go.
Traditional calorie restriction destroys muscle and metabolism. Fasting preserves muscle naturally, but most people stop there.
My protocol takes it further: strategic fasting windows combined with high-intensity strength training, so you're not just maintaining muscle, you're building it while burning fat.
