THE BASICS

WHAT FASTING ACTUALLY MEANS.

Fasting is simply a period of time without consuming food or meaningful calories.

It can take many forms — from extending the time between meals to longer, planned fasting periods.

The principle is simple. The execution should be too: understand your routine, stay adequately hydrated and avoid turning fasting into something unnecessarily complicated.

COMMON FASTING APPROACHES

  • TIME-RESTRICTED EATING

    Eating within a defined daily window and fasting for the remaining hours.

  • ONE MEAL A DAY

    A routine built around one main meal within the day and a longer fasting period between meals.

  • 24-HOUR FASTING

    A full day without food, often structured from one meal to the same meal on the following day.

  • EXTENDED FASTING

    Fasting periods that continue beyond 24 hours and require more planning around hydration, nutrition and individual circumstances.

HYDRATION

FASTING CHANGES FOOD INTAKE. NOT THE NEED FOR WATER.

Water remains essential during fasting, and electrolytes such as sodium, potassium and magnesium continue to play normal physiological roles in the body.

Longer fasting periods can also change how people approach hydration, making a simple and consistent routine increasingly important.

FastFuel was developed around this idea: a straightforward electrolyte and taurine formula without added sugar or unnecessary complexity.

A SIMPLE FASTING ROUTINE

  • WATER


    Still or sparkling water can form the base of a fasting hydration routine.

  • COFFEE & TEA


    Unsweetened black coffee and plain tea are commonly used during fasting, depending on personal tolerance and the type of fast being followed.

  • ELECTROLYTES


    Electrolytes can be included as part of a structured hydration routine, especially when fasting periods become longer or more demanding.

CONSISTENCY

SIMPLE ENOUGH TO REPEAT.

Fasting does not need to become a competition in duration or restriction.

A sustainable routine is one that fits your schedule, can be repeated consistently and does not require unnecessary complexity.

Start with an approach that suits your lifestyle, pay attention to hydration and nutrition, and adjust the structure when your circumstances change.

BREAKING THE FAST

THE FAST ENDS. THE ROUTINE CONTINUES.

Breaking a fast does not need to become a reward or an excuse to overcompensate.

Return to food deliberately, with a meal built around nutrient-dense ingredients and an amount that suits your individual routine.

Protein, whole foods and adequate hydration can provide a simple foundation, while highly processed foods and excessive sugar can be kept to a minimum.

FAST RESPONSIBLY

FASTING IS INDIVIDUAL.

Fasting is not appropriate for everyone, and longer fasting periods require greater consideration.

Individual needs can vary based on health, medication, pregnancy, age and other circumstances. If you have a medical condition, take medication, are pregnant or breastfeeding, or are unsure whether fasting is appropriate for you, seek advice from a qualified healthcare professional before fasting.

KEEP THE ROUTINE SIMPLE.

Fasting does not need more complexity.

FastFuel was created as a straightforward way to add electrolytes and taurine to a fasting-focused hydration routine, without added sugar and without turning supplementation into another complicated system.
