Fat Science What Happens to Your Body When You Stop Taking GLP-1s
What really happens when you stop GLP-1 medications — and are the headlines telling you the whole story? The answer is more nuanced than social media wants you to believe.
This week on Fat Science, Dr. Emily Cooper, Mark Wright, and Andrea Taylor break down four recent studies on GLP-1 treatment outcomes, weight regain, and a groundbreaking new drug that could preserve lean mass during treatment. They walk through the methodology behind each paper, explain why two studies asking the same question got opposite answers, and reveal what a new monoclonal antibody called bimagrumab could mean for the future of metabolic treatment.
Key Takeaways
When you stop treating any chronic metabolic condition, the condition returns — that's not failure, that's biology.
Real-world data showed 56% of people who stopped filling GLP-1 prescriptions maintained or continued losing weight — likely because they continued working with their clinician on alternative treatments.
A new monoclonal antibody called bimagrumab showed 11% body weight reduction on its own, while simultaneously increasing lean mass by 3% — without affecting appetite.
When combined with semaglutide, bimagrumab reduced lean mass loss from 28% to just 11% of total weight lost.
Not eating enough while on GLP-1s drives greater lean mass loss — nutrition is still the best tool for preserving muscle.

"It wasn't my failure and it was disease underneath everything. Finding that out — that it wasn't my fault — that was the miracle of the whole process to me." — Andrea Taylor
