Fast 15 is the busy person's “minimum effective” protocol for building a leaner, harder physique. The purpose is to focus on the fewest, most fundamental efforts that produce the greatest conceivable results. Through intermittent fasting and high-intensity kettlebell complexes your body will be instantly stimulated into shedding unwanted body fat and forging lean, hard, functional (read: useable) muscle in its place. 

The brilliance of FAST 15 is found in simplicity:

=> No complicated eating plans

=> No expensive supplements

=> No time-extensive workout routines

The magic is that everything is built around 15:
*15 days

*15-minute workouts (I call these Power 15s)

*15-hour fasts

...And a few other heuristics (mental shortcuts) that make the fat loss feel almost automatic.

Simply, fast during the allotted hours, focus on simple nutritional parameters thereafter, and perform the daily, intense kettlebell routine — and in fifteen days you could (very reasonably) expect to lose anywhere from 7 - 10lbs (some have lost 15lbs!) of unwanted fat and fluid... while significantly increasing strength, improving muscle tone, and unlocking lost flexibility. 

The other benefit of Fast 15 is the increase in productivity and temperance. People often report feeling more alive and alert when following this particular fasting protocol and develop better emotional control when eating. They also tend to report less cravings and hunger over time, along with an overall increase in fortitude and mental stamina — in other words, Fast 15 rids weakness and makes people strong and tough!
