Wonder Why

Feeling anxious all the time can leave you stuck in a rut—but anxiety isn’t just about stress or mindset. Sleep, diet, blood sugar swings, medications, stimulants, and even the gut microbiome can all influence how your body and brain respond.

In this episode of Wonder Why, we explore how anxiety connects to cardiovascular health, exercise performance, hormonal balance, and blood sugar regulation. We’re joined by Dr. Rosa Keller, a nutrition scientist and UCSF-trained Registered Dietitian, who explains how nutrition—especially plant-based foods—can support the microbiome, mood, and long-term metabolic health.

That sudden irritability when you haven’t eaten—better known as being “hangry”—is more than just a mood. It’s your body’s response to shifting blood sugar levels. But is the fix as simple as eating more often?

We’re joined by Karen, a licensed nutritionist and board-certified in integrative and functional nutrition. She specializes in helping people personalize their approach to blood sugar and cardiometabolic health so they can feel more in control every day.

You’re counting macros, sticking to routines, and doing “everything right.” So why isn’t the scale moving? The truth is, weight loss isn’t always the goal—or the full picture of health. Hormones, life changes, and even perfectionism can all play a role in how your body responds.
