Many participants see a drop on the scales during the 5 days.

Some of this is due to loss of glycogen and water, especially in the first few days. As the programme progresses, the body may shift more towards fat as an energy source, which could contribute to fat loss.

How much weight you lose and keep off varies from person to person. It depends on your starting point, how closely you follow the programme, and what you do after the 5 days.

Both are related to fasting and metabolism, but they're not the same thing.

Sportvasten is usually built around a combination of dietary restriction and exercise. 5 Day Fast is a fasting mimicking approach with a structured menu, supplements, shopping list and exercise plan.

A key difference is the scientific basis. 5 Day Fast is based on the principles of research into fasting mimicking diets, where the aim is to mimic certain effects of fasting through a specific balance of calories, fats, carbohydrates and proteins. Sportvasten is less standardised and can vary quite a bit depending on the method, provider or coach.

Looking for a structured 5-day protocol with a menu, supplements and exercise plan? Then 5 Day Fast might be the more practical option for you.

Intermittent fasting usually means adjusting your daily eating window, for example by eating within 8 hours and fasting for 16 hours.

5 Day Fast works differently. You don't follow a strict daily eating window. Instead, you follow a structured 5-day fasting mimicking menu with controlled nutrition, supplements and an exercise schedule.

Throughout the day, you eat the meals and snacks from your menu without an intermittent fasting schedule. The structure doesn't come from limiting your eating window, but from what you eat, the quantities and the balance between macronutrients.

No, 5 Day Fast isn't the same as water fasting.

With water fasting, you don't eat anything. With 5 Day Fast, you follow a structured menu with controlled nutrition, supplements and an exercise schedule.

The aim is to mimic certain effects of fasting without cutting out food completely, making it easier to stick to than water fasting.
