It’s been commended, alongside the 16:8 diet, as one of the diets that function fast. . Some individuals also take on the diet as they can’t lose weight in other methods and have found fasting to be most efficient.

Dr. Michael Mosley states this diet plan: “Consuming well doesn’t just help you lose weight. Good food could boost your immune system, provide energy, and even affect your mood.”

What Is the Fast 800 Diet?

The Fast 800 diet restricts your calorie consumption to 800 daily for the first couple of weeks. You, at that time, progress to the 5:2 stage, where you only need to consume this amount of calories for two days a week while being on a reliable diet on the other five days.

Stage 1

Consist of sticking to 800 calories a day for at least two weeks. This must induce mild ketosis (like the keto diet), which is linked with burning fat.

Must Read: 500 Calorie Diet

Stage 2

The new 5:2. When you’re approaching your weight-loss goal, consume 800 calories on two days of the week, and the others, follow a Mediterranean diet.

During this diet stage, you should enjoy fewer refined and more home-cooked foods, with lots of veggies and fruit and whole grains, beans, lentils, extra fiber, nuts, and a good amount of full-fat dairy and oily fish. Sugar must be decreased or avoided, starchy carbs, such as white bread and white pasta, are gone, and 45-60g of good-quality protein must be taken daily.

Why Is This Stage Significant?

On your two short days, your body would enter a state of ketosis just as it would if you undergo a quick weight loss plan. With the new 5:2, you would lose fat and get a better response to insulin which will successively make it easier for you to keep segment sizes regular through the week.

The new 5:2 also allows those on the plan to experience other fasting benefits, like apoptosis (cleaning out of old or damaged cells), tissue regeneration, decreased risk of cancer, enhanced metabolic rate, and reduced inflammation.

Dr. Mosley states, “The Mediterranean diet is the best on the planet. There is this thinking that Italian food is primarily pasta and pizza, but this is not true. It’s loaded with fruit, veggies, nuts, olive oil, and fish – all of which are great for you and have been highlighted to help avoid dementia, strokes, cardiovascular disease, and heart disease and has even been termed in some scenarios to reverse type 2 diabetes.”

The main ingredients of the Mediterranean Diet are:

• Daily intake of vegetables, fruits, whole grains, and healthy fats.
• Weekly consumption of fish, poultry, beans, and eggs.
• Moderate segments of dairy products.
• Limited consumption of red meat.

By being on the Mediterranean Diet at this phase of the Fast800, you could keep on track and stay healthy.

Stage 3

You’ve hit your target, so maintenance is vital. Continue the Med-style method, tossing in the odd fast day when consuming a low sugar diet and moderately low quantity of starchy carbs.

The Very Fast 800: What Is It?

The quick weight loss stage involves consuming 800 calories a day. While limiting calories, the key to feeling satisfied is to eat a moderately low-carb Mediterranean-style diet, high in protein, fiber, and healthy fats.

If this method is correct for you, we suggest that you stay on this phase for a minimum of 2 weeks, though you could follow the plan for up to 12 weeks, relying on your goals and how much weight you have to shed.

Who Is It For?

Significant research has highlighted that being on an 800 calorie a day diet is much more efficient than going “slow and steady”. A quick weight loss plan, with a typical weight loss of around 10kg in 12 weeks, is an approved way to reverse and avoid type two diabetes.

The 800 calorie meal is an intensive weight-loss method; it is not suitable for everyone. As with any diet, you must consult your doctor or healthcare professional before starting the 800-calorie diet. Alternatively, some people begin with The New 5:2 or The Way of Life for slow weight loss or to improve overall health.

How It Works

1. Burning Fat by Flipping the Metabolic Switch

We all utilize two different forms of fuel to work: glucose and fat. If you consume and snack daily throughout the day, your body acquires a continual origin of glucose from food to ignite your muscles. Any additional (if you consume more calories than you burn off through exercise) is then deposited as fat. Although, when you spend some time fasting and reducing your consumption of carbs, the glucose temporarily goes out, and your body has to switch to receiving fat from your fat deposits to burn as fuel. Scientists termed this fuel transfer ‘flipping the metabolic switch.

2. Improving Insulin Resistance by Giving up Snacking

High sugar levels (from sweet, carbs meals) regularly in your blood destroys your arteries and nerves. Sugar in high amounts is toxic to the cells.  

Insulin’s function is to regulate your blood glucose levels after you have taken food. In a state of health, it releases the sugar from your food into muscle cells to be burnt as fuel. If you are “insulin resistant”, your muscles would find it tough to absorb this energy. Instead, it gets deposited in your fat cells.

The problem is that your body still requires fuel, so you continue to feel hungry and go out for snacks. When insulin resistant, many calories you absorb get redirected into your fat cells. You put on weight and remain hungry.

Deficient calorie diets are hard to follow

Deficient calorie diets are less likely to be nutritionally absolute as they give far fewer calories than required to maintain a healthy weight. The suggested daily calories are 2,500 for men and 2,000 for women.

It is not a very easy diet to follow. Side effects are the following:

• feeling hungry
• feeling low on energy
• a dry mouth
• constipation or diarrhea
• headaches
• dizziness
• cramps
• hair thinning

While deficient calorie diets could cause short-term weight loss, it is probably that the weight would come back on after the diet is finished.

Deficient calorie diets are not a long-term weight maintenance strategy and must only be utilized as a part of a more comprehensive plan.

Deficient calorie diets are not suitable for most people. Deficient calorie diets are not advisable if you are:

• under 18
• pregnant
• breastfeeding
• have had an eating disorder

If a GP thinks a deficient calorie diet could benefit you, they must make sure:

• the diet is nutritionally fulfilled
• the diet is followed for a maximum of 12 weeks (continuously or intermittently)
• you are provided ongoing support after the diet

Deficient calorie diets are the most limited form of dieting, severely decreasing calorie consumption, so medical supervision is significant.

How Will You Feel After One Month?

After being on a week 800 calorie diet for a month, you would lose weight, look slimmer, your metabolism would be faster, you would feel more energetic and positive, and your stress levels would decrease.

Your new lifestyle would make you fall in love with healthier habits, and you would enjoy being in a better place health-wise. You would be proud of yourself for taking the step forward and accomplishing one month of the 800 calorie diet. But before you begin being on the 800 calorie diet, you must understand its safety.

Is the 800 Calorie Diet Safe?

Yes, a very low-calorie diet is safe. But there is the chance of going wrong if you misuse it. Women need 2000 calories per day to regulate their weight and physiological functions. To lose weight, women must eat only about 1500 (or less) calories daily. But if one is overweight or obese, which could give rise to life-threatening and debilitating diseases, going on a supervised VLCD is an excellent choice.

What if you do not possess obesity, diabetes, and/or hypertension and wish to use this diet to lose a bit of fat? You must understand that the 800 calorie diet is not for individuals who wish to lose a bit of fat. You could opt for intermittent fasting or a 1200 calorie diet plan instead.

Here’s a row of precautions you must take if you proceed on the 800 calorie diet to shed weight or improve your health.

800 Calorie Diet Precautions and Safety

• Consult your doctor or dietitian before initiating this diet plan.
• A sudden variation in the diet impacts the body in more ways than one. Do not empower it on the body, as poor calorie consumption may lead to fatigue and diarrhea. Allow your body some time to be comfortable with the diet.
• Do not overdo it – It could be significant and healthy to shed a few pounds but have breaks between weeks. Being on a VLCDs continuously could result in long-term issues in the kidney, liver, and heart functions.
• You could feel nauseous and weak. Consult your doctor immediately.
• Do not follow this diet if you possess hypoglycemia.
• Do not follow this diet if one is pregnant or lactating.

The 800 calorie diet is a very low-calorie (VCLD) that focuses on drastically cutting down your calorie consumption from the usual 2,000 calories daily. It includes a breakfast loaded with protein, fiber, and complex carbs followed by a light lunch and a nutritious yet low-calorie dinner. 

It also suggests drinking fenugreek-soaked water and green tea for their weight loss impacts. Following this diet seven days, a week may increase your metabolism and help manage type-2 diabetes, hypertension, and obesity. Although, do not overdo this diet and talk to your doctor before beginning it.
