What is autophagy during fasting?
A cellular recycling process where cells degrade and clean out damaged organelles and misfolded proteins, typically peaking after 24 to 48 hours of fasting.
Estimate fat loss and body weight reduction from intermittent water fasting.
Estimates projected fat loss, glycogen depletion, and metabolic ketone transitions during intermittent and multi-day water fasting protocols.
Daily Fat Loss = Net Calorie Deficit / 7,700 kcal per kg fat | Water Loss = Initial Glycogen Bound Water (~1.5–2.5 kg)
Models metabolic phases: Glycogen Depletion (0–24 hrs), Gluconeogenesis (24–48 hrs), Ketosis (48–72 hrs), and Protein Conservation.
Inputs: Fast Duration = 72 Hours (3 Days) | Maintenance TDEE = 2,200 kcal/day
Summary: Fast Duration = 72 Hours | Adipose Fat Lost = 0.86 kg | Temporary Water Drop = 1.8 kg | Total Scale Loss = 2.66 kg
A cellular recycling process where cells degrade and clean out damaged organelles and misfolded proteins, typically peaking after 24 to 48 hours of fasting.
Headaches are usually caused by acute electrolyte depletion (hyponatremia) as insulin drops and the kidneys excrete sodium; drinking water with electrolytes resolves this.
Pregnant or nursing women, individuals with a history of eating disorders, type-1 diabetics, and underweight individuals should not water fast without medical supervision.
