Basics of the ProLon® Fasting Mimicking Diet


The fasting mimicking diet is an alternative to fasting. However, it can have several benefits for your overall health and wellness. We will discuss everything you need to know about the regimen. The article below describes how to do it, its benefits, and how it’s different from normal fasting. The benefits of the fast mimicking diet will have you wanting to try it for yourself.

What is the Fasting Mimicking Diet?

The fasting mimicking diet is a type of modified fasting. The regimen produces the same benefits of fasting by eating small amounts of food. The fast mimicking diet generally lasts about five days and it includes a healthy protocol of carbohydrates, proteins, and fats.

Calories are also maintained at approximately 40 percent of the average calorie intake. This permits the human body to remain nourished without the stress of normal fasting. Calorie restriction can cause health issues, however, the fast mimicking diet is safe and effective. Below, we will discuss just how much the fast mimicking diet differs from traditional fasting.

Traditional Fasting Vs Fast Mimicking Diet

The fasting mimicking diet is always compared to intermittent fasting. There are many myths about these types of modified fasts. Some claim that our muscles waste away while others claim that they change our metabolism, and that it’s downright unhealthy.

The health issues discussed above may be true for a person who’s actually restricting their calorie intake. Some types of fasting may cause metabolic damage which may not be recommended for people with underlying health conditions. However, the fast mimicking diet gives you all the advantages of fasting without the side effects. Below are the benefits of the fast mimicking diet.

Benefits of the Fast Mimicking Diet

The benefits of the fast mimicking diet are essentially the same as those of regular fasting. The benefits are listed below.

The fast mimicking diet “tricks” the human body into feeling as though it’s fasting. Now that we have discussed what this alternate form of fasting is and why it is worth doing, the following advice will demonstrate how to do the diet itself.

How to do the Fast Mimicking Diet

Research studies have found that the best results for the fasting mimicking diet occur in about five days or when your glucose ketone index drops below 1.0. Doing this regimen anywhere between 3 to 7 days is also beneficial. The regimen should also be repeated every month to fully experience its benefits, unless otherwise instructed by a healthcare professional.

If you’re interested in monitoring your fasting outcomes, you should consider quantifying specific biomarkers. This could be measured through lab tests before and after following the fasting mimicking diet. Measuring blood glucose, ketones, and weight changes every day can also be helpful to determine your biomarkers. You might also want to set up your environment by:

  • Telling friends and family about what you are doing and asking them for their support.
  • Eliminating any snack foods at home or work that might interrupt your regimen.
  • Giving yourself more time to sleep, as you will probably be more exhausted than usual.
  • Planning for exercise and physical activity every day. But keep away from intense workouts during this time.

Now that we discussed how you can do the diet, let’s discuss the basics of the fast mimicking diet.

The fasting mimicking diet provides the same great benefits of fasting while still providing your body with some nourishment. If you are following this regimen, make sure that you maintain a low-calorie intake and utilize appropriate supplements to achieve ketosis without experiencing health issues. Set up your environment for the diet. And if you decide to blend the ketogenic diet with this alternate form of fasting to get into ketosis faster, you can achieve the maximum advantages out of the two regimens. Be sure to consult a healthcare professional before following the fasting mimicking diet.

Fasting Mimicking Diet Basics

Some people today might eat a slightly higher amount of calories the first day as they ease into the fasting mimicking diet. They might then decrease their total caloric intake. You also want to make sure you eat smaller amounts of foods which are easy to digest.

ProLon® offers a pre-packaged box which contains all five days’ worth of meals for you to do the diet. The meals are all plant-based. One day, by way of instance, offers tea and a nut bar for breakfast, a small portion of vegetable soup and a few kale crackers for lunch, several olives in the afternoon, and finally another small portion of vegetable soup for dinner.

You can also do the fasting mimicking diet without the need for a pre-packaged box like ProLon®. Simply follow the right proportions and plan out how you will space them out every day. Macros for the fast mimicking diet are 34 percent carbohydrates, 10 percent protein, and 56 percent fat for the very first day and 47 percent carbohydrates, 9 percent protein, and 44 percent fat to the rest days.

A cup of black tea and coffee every day are generally allowed. Just make sure they don’t contain any added sugars or oils. Remember that people with health issues should consult a healthcare professional prior to doing the fast mimicking diet in your own home.


Dr. Anthony Gusting followed a four-day ketogenic fasting mimicking diet. Every day, he consumed different amounts of bone broth, coconut milk, coconut oil, BCAAs, and exogenous ketones. Avocados and grass-fed butter can also be included in the fast mimicking diet. This is a great way to combine the ketogenic diet with the fasting mimicking diet to benefit from the two regimens.


Taking nutritional supplements can also make the fasting mimicking diet easier by providing enough nutrition. These may include:

  • Electrolytes like magnesium and salt to replenish any lost during water loss
  • Grass-fed liver tablets to provide micronutrient support
  • Branch chain amino acids, or BCAAs, to help prevent loss of lean tissue
  • Greens powder to provide micronutrients
  • Algal oil or cod liver oil for omega-3s

You may also take exogenous ketones to achieve ketosis through the keto diet. The fast mimicking diet can also help you achieve ketosis before following a ketogenic diet. Below, we will discuss how the fast mimicking diet promotes ketosis.

Ketosis and the Fast Mimicking Diet

The fast mimicking diet is an excellent way to prepare you for the ketogenic diet. This is because it allows you to get into ketosis. Additionally, eating keto foods makes it possible to remain in ketosis throughout the regimen. To follow a ketogenic fasting mimicking diet you must maintain your macros over the suitable range of 5 to 10 percent of carbohydrates, 20 to 25percent of proteins, and 70 to 80 percent of fats. If you’re unsure about whether you’re properly maintaining your macros, always choose something with more fat.

Additional Topic Discussion: Acute Back Pain

Back pain is one of the most prevalent causes of disability and missed days at work worldwide. Back pain attributes to the second most common reason for doctor office visits, outnumbered only by upper-respiratory infections. Approximately 80 percent of the population will experience back pain at least once throughout their life. The spine is a complex structure made up of bones, joints, ligaments, and muscles, among other soft tissues. Injuries and/or aggravated conditions, such as herniated discs, can eventually lead to symptoms of back pain. Sports injuries or automobile accident injuries are often the most frequent cause of back pain, however, sometimes the simplest of movements can have painful results. Fortunately, alternative treatment options, such as chiropractic care, can help ease back pain through the use of spinal adjustments and manual manipulations, ultimately improving pain relief.
