The Fast 800 is a combination of intermittent fasting and a Mediterranean-style eating plan
The plan starts with a rapid weight loss phase that lasts between two and 12 weeks, during which you follow an 800-calorie daily eating plan. This initial stage is designed to switch the body into a mild ketosis. The diet is moderately low-carb and Mediterranean-style, with lean protein sources and vegetables. The Mediterranean-style diet promotes a daily intake of fresh vegetables, quality protein, and healthy fats, including anti-inflammatory foods that help keep blood sugar levels stable.
The Fast 800 is flexible, and there are three approaches to follow: The Very Fast 800, The New 5:2, and The Way of Life. The approaches are designed to be integrated into your life and can be switched between as your needs change. For example, you might choose to follow The New 5:2 but switch to The Way of Life over a holiday period.
The Fast 800 also includes weekly exercise plans with guided videos for high-intensity interval training (HIIT), resistance, and stretching, ranging from low-impact to advanced levels. Additionally, it offers weekly mindfulness content and meditations to manage stress and promote wellbeing.

The plan starts with a rapid weight loss phase that lasts between two and 12 weeks
The Fast 800 diet is a combination of intermittent fasting and a Mediterranean-style eating plan, with optional meal replacement shakes. The diet starts with a rapid weight loss phase that lasts between two and 12 weeks. During this initial phase, adherents follow an 800-calorie daily eating plan, consisting of a moderately low-carb, Mediterranean-style diet, with lean protein sources and vegetables. The Mediterranean-style diet promotes a daily intake of fresh vegetables, quality protein and healthy fats, including anti-inflammatory foods that help to keep blood sugar levels stable.
The rapid weight loss phase is not suitable for everyone and is not designed to be followed long-term. It is typically only recommended for those with a lot of weight to lose, who require fast results, have reached a weight-loss plateau, or have type 2 diabetes. This phase can help those who are overweight or obese based on their BMI to reach a healthier BMI.
During this initial stage, meal replacement shakes are available on days when cooking is not possible. These shakes are designed to be high in protein, fibre, and healthy fats, and to help stave off hunger. However, if you choose not to use meal replacement products, micronutrient intake may be low, and a vitamin and mineral supplement may be needed. The plan recommends no more than two shakes per day or ten per week, with the emphasis instead placed on whole, natural foods.
The Fast 800 diet is flexible, and adherents can easily switch between each approach as their needs change. The rapid weight loss phase is not meant to be followed long-term and is instead intended as a kick-start to weight loss, after which adherents can transition to a more gradual weight loss approach or a long-term maintenance approach.

The diet is not suitable for everyone and a healthcare professional should be consulted before starting
The Fast 800 diet is not suitable for everyone, and a healthcare professional should be consulted before starting. This is an intensive approach to weight loss and not everyone can tolerate it. The diet is based on a moderately low-carb, Mediterranean-style eating plan, with optional meal replacement shakes. The plan starts with a rapid weight loss phase that involves eating 800 calories a day for up to 12 weeks.
The Fast 800 diet is not a safe option for everyone. The NHS advises that, for most people wanting to lose weight in a safe and sustainable way, a reduction in calorie intake to 1,900 calories for men and 1,400 calories for women is recommended. The Fast 800 diet is typically only followed if you have an obesity-related complication that would benefit from rapid weight loss.
It is important to consult a healthcare professional before starting the Fast 800 diet, especially if you are under 18, elderly, have a pre-existing medical condition (including type 2 diabetes), or are on medication. A GP's support may be needed to make changes to medication and monitor blood sugar or blood pressure levels. Additionally, if you are taking warfarin, are on blood pressure tablets, or are pregnant, breastfeeding, or undergoing fertility treatment, seeking medical advice is crucial.
The Fast 800 diet may also be challenging due to hunger pains, especially if you choose the 'real food' version without meal replacement products. Micronutrient intake may be low in this case, and a vitamin and mineral supplement may be necessary. Furthermore, the diet involves intermittent fasting, which may be difficult to stick to due to increased feelings of hunger.
