The Fast 800 by Dr. Michael Mosley has become one of the most talked-about approaches to weight loss and health improvement in recent years. Built on the principles of intermittent fasting and calorie restriction, this program emphasizes rapid but safe weight loss, balanced nutrition, and long-term healthy habits. Many people are drawn to the Fast 800 Michael Mosley method because it promises not only to help shed excess weight but also to improve blood sugar levels, energy, and overall well-being. Understanding how the plan works, what foods are recommended, and what to expect can make it easier to follow and achieve sustainable results.
What Is the Fast 800?
The Fast 800 is a structured dietary plan designed by Dr. Michael Mosley, a British doctor, journalist, and author known for his work on health and nutrition. The program centers around eating 800 calories per day for a specific period, usually 8 to 12 weeks, before transitioning to a more flexible maintenance plan. Unlike extreme crash diets, this approach is intended to be medically safe and nutritionally balanced, focusing on whole foods rather than processed options.
The Science Behind the Fast 800 Michael Mosley
The Fast 800 combines elements of several well-researched strategies
- Intermittent fastingRestricting eating hours to allow the body to burn stored fat more efficiently.
- Very low-calorie diet (VLCD)Limiting calories to around 800 per day triggers rapid fat burning, especially around the abdomen.
- Mediterranean diet principlesEmphasis on vegetables, lean proteins, healthy fats, and whole grains for better nutrition.
Dr. Michael Mosley’s research and experience show that this combination can help reverse type 2 diabetes, reduce insulin resistance, and improve cardiovascular health alongside weight loss.
Phases of the Fast 800 Plan
The program is divided into different stages to make it easier to follow and maintain in the long run.
1. Rapid Weight Loss Phase
This initial stage involves eating 800 calories a day for 8 to 12 weeks. It is strict but effective, often leading to significant weight loss in a relatively short time. Meals are typically high in protein, fiber, and healthy fats to keep hunger under control.
2. The New 52 Phase
Once the rapid weight loss phase is complete, many transition to a 52 approach. This involves eating normally and healthily five days a week, then restricting calories to around 800 on two non-consecutive days. It is less intense but helps maintain results.
3. Maintenance and Lifestyle Phase
The final phase focuses on building long-term habits. Here, the emphasis is on following a Mediterranean-style diet with balanced meals, mindful eating, and occasional fasting days if needed to stay on track.

- Rapid weight loss, often noticeable within the first few weeks

Potential Challenges
While effective, the program can also be challenging, especially in the beginning. Common issues include
- Hunger and fatigue during the first few days of calorie restriction
- Difficulty maintaining strict meal planning in social situations
- Risk of nutrient deficiencies if the diet is not followed carefully
Dr. Michael Mosley emphasizes the importance of nutrient-dense meals and proper hydration to minimize these challenges. Consulting with a healthcare provider is also recommended before starting, especially for those with medical conditions.
Exercise and Lifestyle with the Fast 800
The Fast 800 is not just about food; it also encourages lifestyle adjustments. Regular physical activity is recommended, but intense workouts may not be necessary, especially during the strict calorie phase. Instead, moderate exercises like walking, cycling, yoga, or strength training are encouraged. Sleep and stress management also play a role in long-term success, as both affect weight and metabolism.

The Fast 800 diet can be suitable for many people, including those who want to lose weight quickly, individuals with pre-diabetes or type 2 diabetes, and those looking to reset their eating habits.
