Water Fast Estimator
Estimate your body's transition into ketosis and autophagy. Our tool models the weight loss curve, distinguishing between glycogen-bound water and long-term fat oxidation.
Water Fast Weight Estimator
Estimate potential weight loss (Fat vs. Water) during a metabolic fast. Includes Mifflin-St Jeor BMR integration and glycogen depletion modeling.
Crucial Safety Protocol
Warnings Signs
- Extreme pulse fluctuations (heart palpitations)
- Severe, persistent dizziness or fainting
- Chest pain or shortness of breath
- Mental confusion or severe lethargy
Who Should NOT Fast?
- Individuals with eating disorders
- Pregnant or breastfeeding women
- Anyone under 18 or over 70
- People with Type 1 Diabetes or Kidney issues
Metabolic Phases
When you stop consuming calories, your body undergoes a predictable hormonal shift. Understanding these phases helps manage expectations and maintain safety.
Weight Loss Timeline
Glycogen Depletion: High weight loss (mostly water). Insulin drops. Hunger peaks.
Ketosis transition: Fat burning becomes primary. Hunger usually fades. Autophagy increases.
Deep Autophagy: Maximum cellular repair. Requires strict medical supervision.
The Electrolyte Stack
Essential for any fast over 48 hours to prevent "Fasting Flu" and heart stress:
- Na
Sodium: 3-5g per day (Pink Himalayan or Sea Salt).
- K
Potassium: 2-3g per day (No-Salt or Potassium Chloride).
- Mg
Magnesium: 300-400mg before bed (Magnesium Glycinate).
