The aim is to take away any doubt. You don't have to work out what to eat, which supplements to take, when to take them, or how to structure the 5 days all by yourself. 5 Day Fast has been developed to make the process clear and practical.

How it works
How does 5 Day Fast work?
5 Day Fast works by combining controlled energy restriction with targeted nutrition and supplements.
During the programme, your body gets less energy than normal. The availability of carbohydrates decreases, glycogen stores gradually get lower, and your body starts to rely more on fat as an energy source. As the programme progresses, ketone production might increase.
At the same time, the load on your digestion is reduced, because your food intake is temporarily decreased and you only take in fresh, healthy products.
5 Day Fast builds on fasting mimicking research and makes copying a five-day fast practical: every day you know what you're eating, which supplements you're taking, and how to stay active.
On the first day, your body mainly uses stored carbohydrates, also known as glycogen. Because glycogen is stored alongside water, the number on the scales might drop quite quickly.
This early weight change is mostly down to water and glycogen, certainly not just fat.
As glycogen availability drops, your body starts using more fat for fuel. Ketone production increases too.
Some people feel pretty stable during this phase. Others might notice more hunger, less energy, or changes in focus. That's completely normal and depends on your starting point, sleep, stress, and any previous fasting experience.
On days 4 and 5, your body gets better adapted to using fat and ketones as an energy source. The digestive load stays lower and your body is in a different metabolic state to normal. You enter ketosis.
That doesn't mean everyone feels the same. Some participants feel clearer and more energetic, while others still experience lower energy levels. How you feel depends on things like your starting point, sleep, and previous experience with fasting.
The phase after the programme is also important. After 5 days of fasting or fasting mimicking, your body needs to rebuild again. Glycogen stores are replenished. Part of the “water weight” returns with that too. Protein intake becomes more important again. You should also build up your training gradually.
When you use 5 Day Fast periodically, it can contribute to longer-term progress. In the period right after the 5 days, it's often easier to adapt old habits and lock in new habits as your default behaviour.
The results
What results can you realistically expect with 5 Day Fast?
For many participants, the number on the scales drops over the five days. A big part of that is down to losing glycogen and the water bound to it, not just fat. As you get further into the programme, your body uses more fat as an energy source.
5 Day Fast also helps you to take a step back from certain eating habits. For some people, the structure makes it easier to become more aware of snacking, portion sizes, cravings and routine behaviour around food.
Realistic results could be:
• weight loss during the 5 Day Fast, which varies per person
• more use of fat as an energy source
• a structured break from old eating habits
How much of the results you keep depends on your starting point and what you do after the 5 days. Results vary per person. 5 Day Fast doesn't guarantee fat loss, better sleep or a specific number on the scales. The programme is most valuable when the 5 days are followed by good nutrition, enough protein, exercise and recovery. Those who repeat 5 Day Fast periodically and use the time in between to build healthy habits usually get the most out of it.
