What Really Happens to Your Body During a 5‑Day Fast — And How You Can Reap the Benefits Without Going Hungry
Imagine your body as a business. A thriving company brings in revenue to pay for operations, growth, and employee needs—just like your body uses calories to fuel cells, organs, and systems. But what happens when the cash stops flowing?
That’s exactly what happens when you stop eating during a fast.
Phase 1: Using Up Reserves (Day 1)
Think of the first day of fasting like a company losing its income stream. To stay afloat, it begins dipping into savings. Your body does the same—it pulls from liver glycogen and muscle stores for energy. This is the science behind intermittent fasting and why it supports weight loss.
Phase 2: Operational Optimization (Days 2–3)
If the company still has no revenue after a few weeks, it begins tightening internal operations, cutting unnecessary spending, and using existing materials to survive. Your body responds the same way by activating autophagy—a powerful cellular clean-up process that recycles damaged cells, organelles, and proteins to survive and thrive under the stress of fasting.
Phase 3: Full Reset & Renewal (Days 4–5)
At this point, the business has to make tough calls—letting go of inefficient systems and staff to stay lean and focused. In your body, this means eliminating old, dysfunctional cells and replacing them with new, younger, and more efficient ones. This regeneration is why prolonged fasting has been hailed for its potential to support healthy aging, metabolic health, and cellular repair.
This groundbreaking connection between fasting and cellular renewal was discovered by Professor Valter Longo at the Longevity Institute at USC. His research has been featured by TIME Magazine, which named him one of the Top 50 Most Influential People in Healthcare.
But Let’s Be Real—Fasting for 5 Days on Water Alone Is Hard
Extended fasting can come with side effects: fatigue, nutrient depletion, and electrolyte imbalance. That’s why Prof. Longo and his team, backed by the NIH, created the Fasting Mimicking Diet (FMD)—a scientifically formulated, plant-based program that allows you to eat while keeping your body in a fasting state.
