ProLon Frequently Asked Questions

What are the benefits?

Potential benefits include:

  • Supporting the body’s natural processes of cellular clean-up and cell renewal
  • Supporting overall metabolic health and maintaining healthy systolic blood pressure*
  • Inducing fat loss without decreasing lean body mass*

*(Results were based on 3 consecutive monthly cycles)

Will I lose weight?

ProLon has been shown to help people lose an average of 5.7 lbs. of fat and 1.2 inches off their waist circumference, while preserving lean body mass. These benefits were seen in a clinical trial where participants consumed ProLon once per month, for 3 consecutive months (study source).

One of the most obvious visual differences will be a loss in fat. Excitingly, the weight loss includes the “bad fat” which clumps around internal organs, known as visceral fat. Whilst lean muscle mass gets maintained.

Showing the location of visceral fat, and how it compares to regular fat we think of (subcutaneous)

How big are the meals?

On the first day you’re allowed more food (~1100 calories) than the following four days (~800 calories). Day 1 your food looks like:

And then days 2 to 5 it looks more like this each day:

You’ll notice day 1 has more bars, and doesn’t include the L-drink.

How should I prepare for the fast?

Leading up to your ProLon 5-day fast, you might be thinking, is there anything I should do to get my body ready for this?

There are at least 3 areas to look at:

1) Start Reducing Your Caffeine Intake

On the ProLon diet it’s requested in the instructions that you only consume what’s in the box for each of the 5 days. With at most, if you need it, 1 cup of tea or coffee each day. For heavy coffee drinkers this restriction could come as a shock to the caffeine dependent body. Leading to potential caffeine withdrawal, which can feel uncomfortable, and may manifest itself with a headache, irritability and tiredness.

Cutting down on food is hard enough as it is, so there’s no need to pile on the difficulty.

With this in mind, it makes sense to start cutting down on your caffeine intake in the lead up. Perhaps by switching to de-caffeinated versions of your favourite beverages.

2) Reduce Sugar & Junk Food

Whilst caffeine is without doubt physiologically addictive, sugar can also be addictive, even if it’s predominantly psychological. Because of this, if you current eat a lot of junk, it makes sense to try and reduce it going into the fast.

3) Eat a Healthy Diet Prior

If you’d like some inspiration on your diet leading up to the fast, this meal plan was shared by ProLon ambassador Felice Gersh (click on it to view a bigger version):

What day is the best day to start?

Now of course you can start the fast on any day of the week you wish. But something that becomes very apparent during the fast is that eating is often as much about fun and excitement, as it is about satiating hunger. And not eating gets very boring very quickly.

Many people decide to start the fast mimicking diet on a Sunday night so they can engage normally in social eating the following weekend. Note that when you finish on the Friday night (last ProLon meal), you don’t resume your normal diet until you wake up on Saturday.

What should I eat after the fast?

For 24 hours following the end of the ProLon, people should follow a diet based on:

  • Soups
  • Complex carbohydrates (vegetables, cereals, pasta, rice, bread, fruit, etc.)

Minimizing consumption of:

  • Fish, meat, saturated fats, pastries, cheeses, milk, etc.
  • Anything too heavy on the stomach

Most people’s reaction (mine included) is to want to feast upon finishing.

Problem is, both your stomach and your gut bacteria have already adapted to the low, restricted foods you’ve been eating, and struggle to handle the big intake of new foods.

This can lead to some uncomfortable stomach ache, and potential trips to the bathroom.

However, if you can manage to take it easy on day 6 with food, you should be in for a smoother ride thereafter.

Which Soup Variety Should I Buy?

Up until August 2019 ProLon had only 1 version of their diet. Since then they’ve introduced the “Soup Variety 2” box on when you go to make an order.

Soup variety 2 swaps out:

  • Mushroom
  • Minestrone
  • Minestrone with Quinoa
  • Vegetable Soup

And adds in:

  • Butternut Squash
  • Butternut Squash with Quinoa
  • Spinach with White Bean
  • Black Bean

Below we’ll take a look at how these new soups look, and taste!

Butternut Squash Soup

This soup has a thick texture (owing to the rice flour they added) which makes it feel more substantial as a meal. If you’re familiar with butternut squash – then it tastes just like that – but with a slightly tart (sour) taste to it.

Butternut Squash with Quinoa Soup

This was my favourite of the two butternut squash soups. Whilst I liked the thickness of the “butternut only” version (this one is more watery) I think overall the flavour is slightly nicer.

Spinach with White Bean Soup

In contrast to the sweeter tasting butternut squash soups – this one (unsurprisingly) tastes more of spinach leaves. It’s perhaps a bit bland, but probably quite healthy!

Black Bean – L-Nutra only recently added Black Bean (swapping out the minestrone), and I haven’t yet done a fast with it in to take a picture of.

As far as your decision goes, it’ll come down to which soups you like the look of more, and if you have any special dietary needs that one will cater for more than the other. If you’d like to see the new soup’s ingredients list, look here:

Can I Add Herbs & Spices to the Soups?

If you’d like to “spice up” the soups, then the good news is you can. I’ve written a guide here, that provides (tried and tested) recipes for each of the soups.

ProLon’s official guidance on this is 1 teaspoon of herbs and spices (maximum) per day. In line with this the receipe’s each use up to 1 teaspoon, which means you can only “spice up” 1 of your 2 soups each day.

See ProLon Soup Tips – How to add some flavor and spice to the soups for all the recipes.
