Intermittent Fasting Collection

While periodic prolonged fasting is a key element of longevity, what - and when - we eat between those fasting cycles is just as important. Incorporating intermittent fasting (IF) methods such as time-restricted eating (TRE) into your daily routine can help maintain the benefits of your Prolon 5-Day Fasting Mimicking Diet (FMD), supporting healthy aging, energy levels, weight management, sleep, and metabolic health.

Prolon offers a range of Fasting Support products designed to extend your fat-burning and fasting window while still providing nourishment, as well as offer a deeper reset between FMD cycles.
