The Commercialization of Intermittent Fasting Apps
Intermittent fasting is biologically simple: give your digestive tract a scheduled rest to deplete liver glycogen and stimulate cellular autophagy. Yet the app ecosystem has increasingly gated basic countdown clocks and history logs behind predatory trial paywalls charging up to $14.99 per month.
The Metabolic Stages of Fasting
Key Physiological Milestones
• Hour 0–4: Anabolic phase — blood glucose elevated.
• Hour 4–12: Catabolic transition — insulin drops, glycogen stores decline.
• Hour 12–16: Ketosis onset & fat oxidation accelerate.
• Hour 16–24: Autophagy peak — lysosomes recycle senescent cellular debris.
