How To Do The Fast 800
The Fast 800 is the umbrella term for a healthy lifestyle based on scientific evidence, encompassing diet, movement and mindfulness.
It’s not just 800 calories
The goal of The Fast 800 and our online programme is to empower you with the tools and knowledge to live a healthy lifestyle long-term. As a result, there are three flexible dietary approaches that can be followed:
- The Very Fast 800
- The New 5:2
- The Way of Life
Every approach follows the principles of a moderately low-carb, Mediterranean-style diet, one of the most researched and scientifically-praised diets. These approaches are designed to suit your goals and circumstances, and you can switch between each approach as your needs change. There is likely to be an approach suitable for you, whether you’re looking to lose a lot of weight for better health, or want to eat in a way that will support healthy ageing and promote longevity.
How to transition between approaches
When you join The Fast 800 online programme, your personalisation questionnaire will determine the most appropriate approach for your start. From there, you’ll learn how to move through the approaches as your goals and needs change.
Weight loss is not linear and being aware of this is important; with social events, holidays and hormones, it is likely, and completely normal, that unwanted weight will creep back on or be harder to lose at times. If this does happen and you want to shift it quickly, you can change your meal plan back to The Very Fast 800 and follow it for a short period of time (we recommend just two weeks) or follow The New 5:2 for a more gradual approach. Alternatively, you can use the approaches in planning for events, holidays or periods that might be trickier to navigate.
For example, you might choose to follow The New 5:2, but switch to The Way of Life over a holiday period. If you come back from a holiday feeling sluggish or want a kick-start back into fasting, you might do a week or two of The Very Fast 800, before transitioning back into The New 5:2 long-term. The approaches are designed to integrate seamlessly into your life.
An example journey
Everyone is different, however, here’s an idea of how a member who starts The Fast 800 with a lot of weight to lose might move between the approaches throughout their first year.
- Do up to 12 weeks of The Very Fast 800
- Transition to The New 5:2 with some TRE, continuing until they reach a healthy weight
- Switch to The Way of Life, still practising TRE but perhaps adjusting eating and fasting windows
- If weight does creep back on, transition to The New 5:2, potentially increasing their TRE fasting window, or do a short reset of two weeks on The Very Fast 800 before moving to either of the long-term approaches.
Alongside diet, this person would also do a few short sessions each of resistance exercise and high-intensity interval training weekly, and regular mindfulness activities.
Progress markers to look for:
Not all progress is reflected in the numbers on the scale. If you’re not seeing much change in your weight, look for other signs of progress:
- decreased waist as well as other body measurements;
- healthier hair, nails and skin;
- better quality sleep;
- increased energy and fewer “crashes”;
- improved fitness;
- changes in how your clothes fit;
- improved digestion;
- clarity of mind; and
- reduced cravings.
“Five months after starting The Fast 800 I reached my target of three stones lost. I’ve gone on to lose a few more pounds to bring my total to 45lbs. I have a whole new figure, necessitating a whole new wardrobe! I feel wonderful, am much more active, and have no joint pain. This WORKS!”
Flexibility and finding what works for you are pivotal in maintaining a long-term, sustainable lifestyle. The Fast 800 is designed to complement your life and any event, holiday or challenge that comes with it.
