He first dives deep into GLP-1 agonists, most notably semaglutide and tirzepatide, which originally came to market as diabetes drugs but are now being studied and prescribed for weight loss. He walks through the data and compares the effectiveness of the two drugs, the side effects, and perhaps more importantly, his reservations around wide use of these drugs and who he would consider to be a candidate for them. Next, Peter discusses how metformin, another drug originally brought to market for diabetes management, gained popularity as a potential longevity drug even for non-diabetics. Peter gives his take on this possibility and reviews data from a more recent study investigating the question of whether metformin should be used for general "geroprotection."</p> <p>If you're not a subscriber and are listening on a podcast player, you'll only be able to hear a preview of the AMA.

Actionable Insights

1. Seek Professional Medical Advice

This podcast is for general informational purposes only and not a substitute for professional medical advice; always seek assistance from healthcare professionals for any medical conditions.

2. Prioritize Insulin Sensitivity

When addressing type 2 diabetes, the primary goal should be to increase insulin sensitivity, as this will ultimately result in a reduction in blood glucose levels.

3. Evaluate GLP1 Use Critically

Critically evaluate the use of GLP1 agonists for weight loss, especially if not genuinely overweight, as many individuals seek them for minor cosmetic weight loss rather than medical necessity.

4. Explore Gyroprotective Drugs

Consider exploring “gyroprotective” drugs such as rapamycin, SGLT2 inhibitors, or metformin, as they appear to act broadly across various hallmarks of aging to improve overall lifespan and healthspan.

5. Lower Blood Glucose Strategy

An important strategic plan to lower blood glucose involves using things that either stimulate insulin release or inhibit glucagon release, as both actions reduce blood glucose levels.

6. Listen to Richard Miller (148)

To understand the science, testing, and considerations for “gyroprotective” drugs, listen to podcast episode 148 featuring Richard Miller for amazing insights.

7. Consider Oral Semaglutide

If you prefer not to inject or face refrigeration challenges, consider oral semaglutide as an alternative to injectable GLP1 agonists, though it is also very expensive.

8. Understand GLP1 Agonists

If you are thinking about taking, currently taking, or curious about GLP1 agonists like semaglutide (Ozempic, Wegovy) or terzepatide, listen to this episode for deep insights and reservations.

9. Explore Metformin’s Benefits

If you have an interest in metformin, particularly its potential “gyroprotective” effects beyond diabetes, this episode delves deeper into the relevant studies.
