Millions of women are on GLP-1 weight loss drugs. The results are real. So are the risks nobody is talking about.

In this solo episode, Dr. Mindy breaks down the new research linking GLP-1 medications to bone density loss and fractures, compares them head-to-head with a fasting lifestyle, and gives you five concrete steps to protect yourself — whether you're on the drugs, considering them, or looking for a free alternative that works just as well.

This is not a takedown of GLP-1 medications. It's the conversation that should be happening alongside every prescription.

What You'll Learn

• The new research from a leading orthopedic surgery conference linking GLP-1s to a 30% increased risk of osteoporosis

• Why menopausal women are at compounded risk when combining GLP-1 drugs with natural bone density decline

• The two theories behind why weight loss drugs may be weakening bones

• How GLP-1 medications compare to a fasting lifestyle: muscle loss, metabolic outcomes, and long-term body composition

• Why fasting preserves muscle while GLP-1 calorie restriction doesn't and the evolutionary mechanism behind it

• When GLP-1 medications are genuinely the right tool (and when fasting is better)

• How to naturally stimulate your body's own GLP-1 production through food and eating patterns

• The foods that amplify GLP-1 and the ones that destroy the gut microbes that make it

• Five action steps to start building a fasting lifestyle today
