Summary

Peptides are everywhere right now—touted as tools for weight loss, muscle growth, faster recovery, and even longevity. But what are they actually, and do they live up to the hype? In this episode of Office Hours, I break down the science behind peptides, how they influence the body’s signaling systems, and how to think about them wisely within a functional medicine approach. In this episode, I cover: • How peptides act as signaling molecules that regulate metabolism, repair, appetite, and energy • The major peptide categories people are using today—from GLP-1 medications to growth and longevity peptides • When peptide therapies may be helpful and the situations where caution is important • Why foundational health habits still matter more than any advanced therapy Peptides may represent an exciting frontier in medicine, but they’re not shortcuts. They amplify the biological environment you already have. When your foundation is strong, targeted therapies can enhance healing and performance. But when your biology is inflamed, sleep-deprived, or metabolically dysfunctional, no peptide can override that terrain. Health isn’t built from hacks—it’s built from habits.

1:01.8	They burn fat and improve sleep. Here you're a gut, boost your brain. But what are they?
1:07.3	And are they the future of medicine or just another biohacking fad? Well, these tiny molecules
1:13.6	control almost everything in your body. So what happens when we start manipulating them? Well,
1:18.6	today we're going to cover what peptides actually are, how they work in the body, and the most
1:24.3	common types that people are talking about. We're also going to talk about who might benefit from them and who should be a little cautious
1:31.7	and also what functional medicine says about them.
1:35.0	Peptides aren't magic.
1:36.2	They're signaling molecules and understanding signaling is health.
1:40.8	So what is a peptide?
1:43.7	Peptides are being called the future of medicine. If you've been
1:47.1	anywhere in your social media, wellness clinics or biohacking podcast, you heard the claims,
