Results with 5 Day Fast

  • Boost your sports performance

    During 5 Day Fast your body learns to use fat for energy, ideal for endurance sports such as running or cycling. You reach the ketosis phase, which allows you to exercise longer and more efficiently with a lower heart rate. This means better performance without your heart working overtime!

  • Burn fat and lose weight

    During 5 Day Fast you can lose 3-7 kilos! This is mainly fluid from your muscles, but you also lose fat - up to 2 kilos if you are slightly overweight. Plus, the more active you are, the more fat you burn! With 5 Day Fast you eat and exercise in such a way that your body starts using fat for energy and that process continues for a while afterwards. This is your chance to become slimmer and fitter!

  • Break unhealthy eating patterns

    With 5 Day Fast you break unhealthy eating patterns. You eat fresh, high-quality vegetables, fruit and nuts and even though you eat less, you feel better. Even if you eat unhealthy immediately after the program, your body will provide immediate feedback from within. With 5 Day Fast you reset and break eating patterns. The result? You feel more energetic, fitter and more vital than ever!

What kind of results can I expect from 5 Day Fast?

With 5 Day Fast you can do a lot of good for your body. Here are a few things you can improve:

  1. Recover : You help your intestines become healthier. This means that your intestines can work better and cause fewer problems, such as with leaky gut.
  2. Stimulate : Your body becomes better at cleaning out unhealthy substances, such as heavy metals stored in fat. It also helps your digestion and improves your ability to burn fat as an energy source.
  3. Regenerate : Your body will "clean up" and renew itself. This means that you become healthier on an organ level, your body clears away old, incorrectly produced proteins (plaque) and even activates stem cells.
  4. Supplement : The program ensures that your body gets the important nutrients it needs.

So, by participating in 5 Day Fast, you do much more than just lose weight. You make your entire body healthier!

Are the results of 5 Day Fast guaranteed?

Yes, results from the 5 Day Fast program are guaranteed for everyone if you eat and drink what is on the menu and stay active according to the proposed exercise plan. The program is carefully balanced to guarantee optimal results. The program is designed so that you consume less energy than your body uses at rest. This automatically activates all kinds of restorative processes in your body, without you having to do anything extra. But please note: it is very important that you stay active and exercise during the five days. The more active you are during your 5 Day Fast week, the greater the positive effect on your body will be!

How much weight can I lose?

By following Ramon Siljade's 5 Day Fast program, you can lose between 3 and 7 kilos in one week. It is important to know that this is primarily fluid that comes from your muscles. This means that after the 5 days you will regain some weight as your body replenishes this fluid. But the good news is that if you're a little overweight, you'll probably also lose 1 to 2 pounds of body fat every time you participate in 5 Day Fast. And remember, the more you exercise and exercise during these five days, the better your results will be. This ensures that your body has to switch completely to fat burning (ketosis) more quickly.

The data from our participants from the past three years shows that participants with a BMI of +25* who do 3x 5 Day Fast in 8 months lose about 6 to 9 kg of body fat over that period.
(*A BMI of 25+ means that you are not extremely heavy, but that you cannot see your abdominal muscles in the mirror. The higher the BMI, the more body fat you will lose after three participations in 8 months)

How does 5 Day Fast help improve my sports performance?

During the 5 Day Fast program you teach your body to use different energy sources in a better way by activating your 'fat burning engine'. Ultimately, your body switches completely to fat burning during 5 Day Fast. This is also known as "being in ketosis". This teaches your body to use fat effectively as an energy source. This improves performance in all sports that require continuous exercise for more than 45 minutes.

Why do you experience that improvement during exercise? This is because your body can better use fat for energy during exercise. If you use more fat as an energy source during exercise at the same running speed, this will result in a lower heart rate and perceived exertion than before at the same speed. Pure profit.

How does 5 Day Fast differ from sports fasting and intermittent fasting?

Although sports fasting and other forms of fasting can produce similar results, 5 Day Fast offers unique benefits.

1. A big difference is that 5 Day Fast only lasts five days and is less intense than, for example, sports fasting.

2. The 5 Day Fast program is backed by more than 30 years of scientific research. Most other forms of fasting have little or no evidence of this. This scientific substantiation is not only crucial to demonstrate the positive effects, but also essential to guarantee the safety of the program. In addition, the same research also shows that your entire muscle mass is preserved if you do a 5 Day Fast. And this is crucial not only for athletes, but for everyone!

3. Another advantage of our program is that we not only help you during the five-day treatment, but also provide advice on how you can integrate healthy food products into your daily life after the program. We offer practical tips on what to eat and where to find these healthy products.

4. Intermittent fasting can mean many things. For most people it means: every day, so structurally, 8 hours of eating and drinking, 16 hours of nothing eating or drinking. This does not have the same scientific basis as 5 Day Fast. And you cannot achieve the same effects that you can achieve with the 5 Day Fast program. Everyone who participates in 5 Day Fast will receive substantiated advice from us immediately after their first participation about which form of intermittent fasting best contributes to good health.

What do I eat during the 5 Day Fast program?

The menu of the 5-day program is completely vegan.

During the 5 days of the program you mainly eat vegetables, fruit and nuts.

When you go shopping, we advise you to choose high-quality products, such as those with an 'EKO' or 'Bio-Dynamic' quality mark.

These products are not only good for you during the program, but also afterwards they help improve your health and ensure a better digestive system.

Does everyone get the same food and supplements at 5 Day Fast, regardless of their weight?

Yes, with 5 Day Fast everyone gets exactly the same amount of food and, with the exception of one supplement (this supplement is based on weight), the same (amounts of) supplements, regardless of whether someone weighs 55 kg or 120 kg.

The reason for this is that everyone consumes food (energy) below his/her resting metabolism (that is your resting energy expenditure). This means that you consume less energy than you would use if you lay still on the couch all day. In practice, the resting metabolism of the 55 kg person can even be higher than that of 120 kg. Finally, all research into the 5 Day Fast program has been done this way. This means we can guarantee both safety and positive effects for everyone.
