[369] - You Might Look Fine…But This May Be Quietly Killing Shift Workers
About this episode
Text me what you thought of the show 😊
You can look fit on the outside and still carry dangerous visceral fat—driving inflammation, insulin resistance, and long-term disease risk behind the scenes.
In this episode, I break down why shift work and circadian disruption make visceral fat more likely—and what you can start doing to bring your energy, metabolism, and blood markers back into line.
In this episode, we cover:
• What visceral fat is—and why it’s metabolically active
• Why shift workers can carry visceral fat while looking “normal”
• How circadian disruption impacts metabolism and digestion
• The role of cortisol, insulin, and melatonin timing
• How sleep loss disrupts leptin and ghrelin—and increases cravings
• Why eating overnight worsens glucose tolerance and insulin response
• The long-term risks: type 2 diabetes, heart disease, and fatty liver
Practical strategies:
• Mediterranean-style eating to reduce inflammation and improve energy use
• Reducing (or eliminating) alcohol to support liver health
• Cutting ultra-processed foods that amplify hunger signals
• Resistance training 3x per week as a non-negotiable
• Daily walking—and short walks after meals for glucose control
• Optional: one weekly high-intensity session for efficiency
• Optimizing your sleep environment and maintaining a consistent wake-up time
• Using tools like DEXA scans and GP checks to measure what you can’t see
