We’ve got the 5:2 diet and intermittent fasting, but now Dr Michael Mosley has created the Fast 800 Calorie Diet, which could see you shed up to 11lb in two weeks. Simply limit your daily intake to 800 calories a day and the benefits will be amazing.
There’s a new diet on the scene and it could finally be the secret to long-term weight loss. Incorporating periods of intermittent fasting along with fast days, while still eating filling, nutritious foods, you’ll not only look amazing, you’ll also give your brain a boost, improve your mood and motivation, potentially reverse and prevent diabetes and reduce blood pressure. And those are just a few of the benefits.
As the founder Dr Michael Mosley says himself, “Eating well doesn’t just help you lose weight. Good food can boost your immune system, give you energy and even impact your mood.
“It can be pretty confusing to know what we should eat to stay healthy. My advice? Turn to the Med.”
This is one of the foundations of the Fast 800 Calorie Diet. Read on to find out more…
What is the Fast 800 Calorie Diet?
The Fast 800 diet involves cutting your calories intake to 800 a day for the first couple of weeks. You then progress to 5:2 stage – where you’re only required to eat this number of calories for two days a week, while following a sensible diet on the other days.
Involves sticking to 800 calories a day for at least two weeks. This should induce mild ketosis, associated with fat burning.
The new 5:2. When you’re nearing your weight-loss target, eat 800 calories on two days of the week and on the others, follow a Mediterranean diet, exercising portion control.
During this period of the diet, it’s advised you enjoy fewer processed and more home-cooked foods, with plenty of vegetables and fruit as well as whole grains, beans, lentils, extra fibre, lots of nuts and plenty of full-fat dairy and oily fish. Sugar should be reduced or avoided, starchy carbs, like white bread and white pasta, are gone, and 45-60g of good-quality protein should be consumed daily.
Why is this stage important? On your two fast days, your body will enter a state of ketosis just as it would if you undertook a rapid weight loss plan. With the new 5:2, you will lose fat and achieve a better response to insulin which will in turn, make it easier for you to keep portion sizes regular during the week.
The new 5:2 also gives those on the plan the chance to experience other fasting benefits, such as apoptosis (clearing out of old or damaged cells), tissue regeneration, reduced risk of cancer, increased metabolic rate and decreased inflammation.
Dr Mosley says, “The Mediterranean diet is the healthiest diet on the planet. There is this perception that Italian food is predominantly pasta and pizza, but this is not true. It’s actually packed with fruit, vegetables, nuts, olive oil and fish – all of which are good for you and have been proven to help prevent dementia, strokes, cardiovascular disease, heart disease and has even in some cases, been known to reverse type 2 diabetes.”
The main components of the Mediterranean Diet are…
- Daily consumption of vegetables, fruits, wholegrains and healthy fats.
- Weekly intake of fish, poultry, beans and eggs.
- Moderate portions of dairy products.
- Limited intake of red meat.
By following the Mediterranean Diet at this stage of the Fast800, you can keep on track and stay healthy.
You’ve hit your goal, so maintenance is key. Continue the Med-style approach, throwing in the odd fast day as and when, eating a low-sugar diet and moderately low amounts of starchy carbs.
