HighGBS: 86 (High Risk)fasting

Fasting Mimicking Diet (FMD)

Developer: Valter Longo

5-day cycles monthly or quarterly

Protocol Overview

5-day low-calorie, low-protein, plant-based diet (800-1100 cal/day) that mimics fasting metabolically while providing some nutrition. Triggers autophagy and stem cell regeneration without full fast. ProLon is commercial product.

Conditions Treated

Longevity

cancer adjunct

metabolic health

immune regeneration

Protocol Steps

5-day protocol: Day 1: ~1100 calories (500 cal carbs, 500 fat, 100 protein)

Days 2-5: ~800 calories (400 carb, 350 fat, 50 protein)

Macronutrient focus: Very low protein (<30g), high healthy fats (nuts, olive oil), plant-based

ProLon kit: Commercial product with everything packaged (~$250/kit), nut bars, soups, olives, crackers, tea

DIY approach: Avocado, nuts, vegetable soups, olives, small amounts of vegetables, herbal tea

Timing: Once monthly for 3-6 months for metabolic benefits, then quarterly for maintenance

Cancer patients: Longo's research shows benefit before/during chemo (consult oncologist)

Activities: Light activity only, rest, no intense exercise

Medications: Adjust with doctor (especially diabetes meds, blood pressure)

Day 6 transition: Resume normal eating gradually, avoid binging

Monitor: Blood work shows improvements in IGF-1, glucose, inflammation markers

Contraindications & Risks

Pregnancy/nursing, underweight, eating disorders, diabetes (med adjustment needed), expensive if using ProLon

Important Notes

Gold-standard research from Valter Longo at USC. Clinical trials show immune regeneration, stem cell activation, metabolic benefits. Safer than water fasting (less extreme). ProLon is convenient but expensive. Can DIY with same macro targets. Used in cancer clinics as adjunct to chemo. Strong science. Most evidence-based fasting protocol. Accessible compromise between normal eating and extended fasting.

Critical Safety Warning

This protocol is documented for educational purposes only. The Gabriel Bullshit Score (GBS) of 86 reflects significant institutional response and controversy. Some alternative health protocols have resulted in serious harm or death.

Always consult with qualified healthcare professionals before beginning any treatment. Do not delay or forego proven medical care.

About GBS Score

The Gabriel Bullshit Score reflects the magnitude of institutional response, controversy, and documented concerns. Higher scores indicate greater institutional pushback, not necessarily inefficacy. This is a research tool, not medical advice.
