Guided Fasting Protocols
Clinically guided fasting for insulin sensitivity and mitochondrial repair
Therapeutic Fasting for Metabolic Health
Fasting is one of the most powerful metabolic interventions available — when done correctly. At Duluth Metabolic, we design personalized fasting protocols that enhance insulin sensitivity, promote cellular repair, optimize fat metabolism, and restore metabolic flexibility.
Unlike unguided fasting or trendy diets, our protocols are clinically supervised, biomarker-informed, and tailored to your individual physiology. We monitor your progress closely to ensure safety and effectiveness.
Types of Fasting Protocols
- Intermittent Fasting (16:8, 18:6) — daily eating windows for consistent metabolic benefits
- Extended Fasting (24-72 hours) — deeper cellular repair and autophagy activation
- Alternate-Day Fasting — cycling between fasting and eating days
- Fasting-Mimicking Diets — low-calorie periods that trigger fasting benefits
- Time-Restricted Eating — aligning eating with circadian rhythms
How Fasting Supports Metabolic Health
Fasting lowers insulin levels, allowing your body to access stored fat for energy. It activates autophagy — your cells' natural cleanup process that removes damaged components. It enhances mitochondrial function, improves insulin sensitivity, reduces inflammation, and promotes metabolic flexibility.
These benefits extend beyond weight loss: improved mental clarity, sustained energy, better blood sugar control, reduced inflammation, and cellular rejuvenation.
What to Expect
We begin with an assessment of your metabolic state, medical history, and goals. Initial protocols are conservative — typically starting with 12-14 hour overnight fasts and gradually extending as your body adapts.
Throughout your fasting protocol, we monitor biomarkers, track symptoms, and adjust timing based on your response. Most clients experience initial hunger that diminishes within 1-2 weeks as metabolic flexibility improves. You'll receive detailed guidance on what to consume during fasting windows, how to break fasts properly, and how to optimize nutrition during eating periods.
