Working Fast

Fasting hacks are framed as transitional tools rather than equivalent to water fasting. Working fasts may include aids such as coffee, fat-based coffee, MCT oil, butter, or prebiotic fiber when they do not substantially raise insulin or mTOR. Bulletproof-style coffee is described as blended coffee with grass-fed butter and MCT oil, intended to keep insulin stable, keep mTOR low, and provide ketones. A working fast is intended to improve ordinary daily performance rather than create a retreat-like spiritual setting. Black coffee, fat-based coffee, and prebiotic fiber are presented as fasting hacks that make fasting easier without substantially changing insulin or mTOR.
