The Fast 800 is flexible. All three approaches follow the principles of a moderately low-carb, Mediterranean-style diet. You can switch easily between each approach as your needs change – some people start with The Very Fast 800 (our 800 calorie diet) if they have a significant amount of weight to lose, or to kick start weight loss, while others start with The New 5:2 or The Way of Life for gradual weight loss or to improve their overall health.
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.

We all use two different types of fuel to function: glucose and fat. If you eat and snack regularly throughout the day, your body gets a continual source of glucose from food to fuel your muscles. Any excess (if you eat more calories than you burn off through exercise) is then stored as fat. However, when you spend some time fasting and lowering your intake carbohydrates, the glucose supply temporarily runs out, and your body has to switch to taking fat from your fat stores to burn as fuel. Scientists call this fuel transfer ‘flipping the metabolic switch’.
Having high levels of sugar (from sweet, carby meals) consistently in your blood damages your arteries and nerves. Sugar in high concentrations is toxic to the cells.
Insulin’s job is to regulate your blood sugar levels after you have eaten food. In a state of health, it pushes the sugar from your food into muscle cells to be burnt as fuel. If you are “insulin resistant”, your muscles find it hard to absorb this energy. Instead, it gets stored in your fat cells.
The trouble is, your body still craves fuel, so you continue to feel hungry and reaching for snacks. When you are insulin resistant, many of the calories you absorb get diverted into your fat cells. You put on weight and stay hungry.
The Very Fast 800 requires following a fasting approach of 800 quality calories every day for a minimum of two and a maximum of twelve weeks. You’re encouraged to incorporate time-restricted eating (TRE), exercise and mindfulness to round out the benefits of The Fast 800 lifestyle.
