What if the explosion of GLP-1 drugs like Ozempic and Wegovy is not a weight loss revolution, but rather a warning sign that something in our metabolic health is fundamentally broken?

Today, we take a deep dive into the lesser-known satiety hormones, such as CCK and PYY, exploring how dysfunction in these hormones could be silently accelerating your aging and sabotaging your health span.

I’m excited to welcome Ashley Koff, a registered dietitian with more than 25 years of experience in functional and integrative nutrition, for a two-part series. In Part 1 today, we break down why your satiety hormones may be underperforming, how this links to aging and longevity, and simple strategies you can start using today to support metabolic health naturally.

How to support your weight-health hormones:

Focus on supporting your digestion first, rather than jumping straight into weight loss or metabolic fixes
Ensure you’re consuming enough protein and amino acids to support peptide hormone production
Reduce gut irritants like alcohol, ultra-processed ingredients, and unnecessary fasting
Nourish your body consistently, especially during times of hormonal change, instead of restricting
View digestive symptoms as signs of dysfunction instead of problems to push through or ignore
