ProLon ReSet is designed to support intermittent fasting (overnight fasts, and fasts lasting less than two days) as part of an everyday healthy lifestyle. If you’re looking for the benefits of prolonged periodic fasting (longer than 2 days) including support for weight loss and fat loss, metabolic health, or a jumpstart to lifestyle transformation, we recommend that you try the ProLon 5-day Fasting Mimicking Programme.
