Is fasting healthy and safe?

For most people, yes. And prolonged fasting contributes to transformative, sustained health benefits. However, if you have a health condition of any kind, or any concerns about fasting, you should speak to your healthcare provider before starting a prolonged fast.

Due to the nature of fasting, people often experience fatigue, headache, dizziness, and difficulty with concentration during the fasting period. These symptoms are generally mild and well-tolerated, and tend to decrease with each successive fast.

ProLon is designed to prevent many of these symptoms of fasting by providing specific macro and micronutrients. However, because it is still a low-calorie program, we encourage you to discuss with your healthcare provider whether the practice of fasting or the use of fasting mimicking diet is right for you. To minimize any risks associated with fasting, please follow these recommendations during the 5-day program: Please avoid the following during the 5-days of the program:

  • Avoid any strenuous exercising or activities that may consume a high level of calories. 
  • Avoid extreme temperature environments like hot tubs and saunas, or driving long distances under strong sun or heat exposure. 
  • Since ProLon is a food-based program, please stop the product should you experience any symptom of an allergic reaction such as a rash, change in voice, swelling or fever.
  • If you feel light-headed or faint, you should eat something, drink juice, or consume a beverage with sugar. If your symptoms do not subside, please contact your physician, or if you feel this is a life-threatening emergency, call 911.
