We recommend consuming the Fasting Shake once daily, as we want people to follow a healthy, balanced diet that includes regular meals throughout the day. It can be consumed in the morning after an overnight fast, or as a healthy snack at any time of day, in addition to meals, to help curb hunger. The impact and safety of consuming multiple Fasting Shakes per day have not been studied, so we recommend consuming only one in the morning or evening, along with a healthy, balanced diet during other meals.
The Fasting Shake is ideal for supporting limited-time fasting and other short-term fasts. If you're looking for the benefits of extended fasting, our ProLon 5-day Program has been extensively tested and safely used by hundreds of thousands of overall healthy consumers and has been clinically proven to provide many benefits and support overall metabolic health when used in multiple cycles.
