5 Day Fast is a structured 5-day fasting mimicking programme.

You don't stop eating completely. Instead, you get an adaptable menu with specific, high-quality vegetables, fruit and nuts, supported by supplements and guidance. Alongside nutrition, the programme also includes daily sport and exercise activities. The goal is to mimic certain effects of fasting, without stopping eating completely.

Want to understand the full programme better before you order? Check out the 5 Day Fast product page.

You get the supplements for the 5 days, access to your menu choice, a shopping list, a handy checklist with clear explanations and instructions, and an exercise plan to support you.

The aim is to prevent guesswork. You'll know what to take, what you can eat, what to buy, and how to structure the 5 days.

5 Day Fast can support various effects, such as a drop on the scales, less strain on your digestion, more awareness of eating habits and a temporary shift towards more fat use and ketone production.

The exact results vary per person. They depend on your starting point, how well you follow the programme and what you do after the 5 days.

Yes, you can work out during the 5 Day Fast. In fact, exercise is an important part of the programme, as it can help your body use stored glycogen and support the transition towards more fat burning and ketone production.

Keep the intensity low. Go for a pace where you can still chat comfortably, and shorten the duration if you need to. Walking, gentle cycling, light jogging or mobility exercises are a great fit.

The goal isn't to perform during the 5 days. The goal is to stay active in a controlled way, support the metabolic shift and avoid unnecessary stress. Avoid high-intensity sessions, long heavy workouts and heavy strength training during the programme.

No, 5 Day Fast isn't suitable for everyone.

The program temporarily lowers your energy intake and therefore asks quite a bit from your body. Don't start if you are pregnant, breastfeeding, actively ill, under 18 years old, or if you have or are recovering from an eating disorder.

If you use medication, have diabetes, a medical condition, a low BMI, or if you're not sure, please consult a doctor or treating specialist before you start.
