Some people go on a very low-calorie diet for rapid weight loss, often consuming only 800 calories a day. This type of diet usually includes special foods such as shakes, bars, or soups to replace meals and for added vitamins. Very low-calorie diets can help a person achieve weight loss of up to 3 to 5 pounds per week.
The NHS advise that for the majority of us to lose weight in a safe and sustainable way, we should reduce our calorie intake to 1,900 calories for men and 1,400 calories for women. Dr Mosley claims that by following the rapid weight loss stage of the Fast 800 you may lose as much as 14kg over 8 weeks.
According to founder Dr Michael Mosley, those who closely follow the Fast 800 plan could see themselves lose up to 11lb in two weeks by limiting their daily intake to 800 calories a day. It's been praised, alongside the 16:8 diet, as one of the diets that work fast.
In addition, consuming as few as 800 calories daily may not give you the energy you need for daily living and regular physical activity, especially if you eat the same foods every day. Talk to your doctor or dietitian to make sure you get the nutrients you need while on a very low-calorie diet.
The 800-calorie rapid weight loss phase is safe for most individuals for up to 12 weeks, as long as you stick to our recommendations, drink plenty of water and use a multivitamin.

It simply takes time. Another common reason why people report not losing weight despite reducing their calories is that they don't give it enough time. Our bodies will do their utmost to hold on to our fat reserves and you often have to be in a calorie deficit for a while before you will see any meaningful weight loss.
The participants on the 800 calorie diet made a gradual return to a more normal diet after the 12 weeks of 800 calories. Both groups were then followed for two years. The results in the rapid weight loss group were astounding. Average weight loss was 10.5kg and nearly ¼ of participants lost over 15kg.
An ideal daily intake of calories varies depending on age, metabolism and levels of physical activity, among other things. Generally, the recommended daily calorie intake is 2,000 calories a day for women and 2,500 for men.
Most adults need a minimum of 2000 calories to sustain metabolism, muscle activity, and brain function. However, too many calories can lead to weight gain and a variety of diseases.
Please note, 800 calories a day (The Very Fast 800) is too low for those who are doing intense or endurance exercise. If you are doing intense/endurance exercise, you will require more energy than most.
Yes, it is possible to lose weight fast and within two weeks healthily and realistically. One way to do it is simply by reducing your calorie intake by 500 to 750 calories per day — you can create a calorie deficit to stimulate weight loss. Another excellent way to shed kilos faster is by being physically active.
Losing around 1.5 to 2.5 kilos of body weight in a month is considered healthy. Losing more than this means you are putting pressure on your bodily functions and internal organs, kidneys especially.
Your portions are too big. Yes, you may be checking the calories per serving but not many people realised just how big the servings should be. Think about cereal; the recommended serving size is considerably smaller than you may think with most brands recommending between 30-40g, which is less than 3 tablespoons.
Is The 800-Calorie Diet Safe? No, it is not. As a general rule, men and women require about 2500 and 2000 calories, respectively, to maintain weight. You should note that this is not a standard number as your recommended daily caloric intake is determined by weight, ages, height and level of physical activity(23).
If you are eating too many refined carbs, and your diet is low in protein, fat, or fibre you may feel hungry more frequently as your body is craving what it really needs. This is why a Mediterranean-style diet is what we recommend, and is at the core of The Fast 800 Online Programme.
For weight maintenance, the Dietary Guidelines for Americans 2020–2025 suggest a range of 1,600–2,400 calories for women and 2,200–3,000 for men — so you could consider anything below these numbers a low-calorie diet. But some popular diet plans take users to extremely low levels.
One of the main reasons that undereating can lead to weight gain is because consuming too few calories can cause your resting metabolic rate to slow down. This means you may burn fewer calories throughout the day.
Dr Michael Mosley's latest diet encourages people to eat 800 calories per day, fast intermittently and replace some meals with nutritious shakes, in a new iteration of his famous 5:2 diet. Dr Michael Mosley has unveiled a new diet that he describes as his “best plan ever”.
An overweight, out-of-shape person who starts a healthy weight-loss diet and exercise regimen may get a bigger bump that first week, maybe up to 6 pounds—but that's fleeting. Even that person will quickly revert to 1-2 pounds per week. So, a realistic healthy weight loss for 12 weeks would be 22-24 pounds.
The Fast 800 diet has quickly become one of the most popular weight loss plans out there, with slimmers typically losing around 10kg in three months. While the plan involves limiting calorie intake to just 800 each day, Michael Mosley's plan ensures that followers receive all the nutrients and vitamins they need.
Consuming 800 calories or less on a daily basis has the greatest effect of slowing your metabolism. Not only does consuming too few calories slow your metabolism while you are dieting, it will also cause your metabolism to stay in “slow-down” mode for a period of time even after you go off the strict diet.
Not likely. Generally an adult maintains their weight on about 2000 calories a day. But even if your particular BMI and metabolism only requires 1500 calories a day to maintain, if you would be eating less than 1200 calories per day. You would most likely be losing weight.
Some individuals try strict eating regimes, such as a 1,000-calorie diet, to lose weight quickly. However, drastically cutting calories does not typically result in sustained weight loss and can have harmful outcomes. Extreme diets have undesirable effects and do not result in sustained weight loss.
