Fasting. With Food.

Our scientifically backed program keeps your body in fasting mode with food 
thanks to two decades of research. Life changing and easy to stick with.

“But wait, how can I fast and eat?”

It’s simple – fasting is a physiological state of being, not just the act of not eating. Our team of doctors and scientists figured out precisely what you can eat without breaking your fast. It's called Fasting Mimicking, a system backed by years of scientific studies.

Give us 5 days, and we’ll show you the power of 20 years of research.

Each kit includes 5 days of breakfast, lunch, afternoon snack, and dinner:
10 tasty soups in a variety of flavors
9 L-bars (Nut-Based, Choco Crisp)
5 packs of olives
3 packs of kale crackers
10 hot tea packets (Spearmint, Hibiscus)
4 L-Drinks
Water bottle

How it works

Fasting programs are everywhere these days, but your body only begins to reap the benefits of fasting after 2 days. Once you hit that point, your body is in cellular rejuvenation mode. That’s why ProLon provides multiple benefits many other plans don’t.




Transforming to a fasting state


Fat burning & ketogenesis


Autophagy clean-up state


Cellular rejuvenation


Renewal & change

The first 48 hours lay the groundwork.
Your body is transitioning into a fat-burning, ketone-production state. You got this.

On day 3, you enter the golden hour: autophagy.
Your body is starting the process of intracellular clean up and rejuvenation. Plus, your body is boosting its use of ketones. Keep going!

The last 2 days welcome cellular rejuvenation.
Your body is still burning fat, and you may notice enhanced mental clarity*. You did it!

*Over 95% of those who used ProLon for the first time said they successfully completed the 5-day fast. Over 60% reported that they experienced greater energy, mental clarity and focus.

Who is ProLon for?

Everyone and every body

ProLon has been studied and found effective and safe for generally healthy individuals with a wide range of caloric needs and body mass indices (BMIs).

We are biologically designed to fast from an evolutionary standpoint. Think about it – our ancient ancestors didn’t have 24/7 access to food. It’s just science!

ProLon is designed for healthy individuals who want to enhance their health or those who struggle with weight and want to take charge of their weight loss.

ProLon is unlike any other fasting program and is based on over 20 years of scientific research. The specially designed meal plan provides you with tasty food and delivers nutrition without activating the body’s food-recognizing sensors, also known as Nutrient-Sensing Pathways. It keeps these sensors below a certain threshold – so it’s essentially a “fast with food.”
