People believe that long-term weight loss can’t be achieved. I know this because 99 percent of diets don’t work and most people who follow them get fatter than they were before.

Many crazy diets exist. There are many crazy diets out there. But a glance through the latest research will reveal that you can lose some or all of your weight if you stick to a healthy diet. 

And, contrary to what many people believe, rapid weight loss diets — like my Fast 800 Keto plan — can be more effective in the short, medium and long term.

Because losing weight fast is motivating. Many studies show that how well you do long-term is directly related to the weight you have lost in the first 4 weeks.

Problems will occur if you let yourself slip back into your old eating patterns — the habits that caused you to gain weight in the first place.

My Fast 800 Keto Plan, published exclusively in The Daily Mail and The Mail On Sunday, has three phases that allow you to return to real-world food without having all your hard work undone.

This week, I’ve been writing about the scientifically-backed and clever principles that underpin this updated version of my weight loss plan.

When hunger strikes 

Remind yourself why you’re doing this. You want to live to a healthy old age, don’t you? Healthy, free of disease, and happy. You can bend down to tie your shoelaces. 

It is important to ensure you get enough protein in every meal. You should also reduce your carbohydrate intake so you can easily slip into the state of ‘ketosis. Your body will naturally search for fat to fuel this state.

One key additional factor which really helps is ‘time restricted eating’ — which encourages you to extend your night-time fast and condense your eating window.

This not only provides the metabolic benefits of serious fasting but also increases the effectiveness of ketosis, which can help to avoid late-night snacks.

You have the option to select whether or not you want two or three meals per days during Fast 800 Keto.

Many people — me included — find that skipping breakfast and having a hearty protein-packed brunch later in the morning really sets me up for the day and makes it much easier to keep my total calorie intake down.

My wife Dr Clare Bailey and Caroline Barton are the ones who created these deliciously filling recipes. They want you to be able to quickly lose weight without feeling hungry.

You can now make your 800-900 calorie fast’ meals much more manageable. Watch Clare and Michael cook on Instagram @drclarebailey.

This plan has a clever twist: it slowly evolves so that you can revert to real-world eating habits without gaining weight.

The second stage (we suggest you keep to stage one for between two and twelve weeks, depending on your weight loss goals) is where you simply eat 800-900 calories a day during the week or for 4 or more consecutive days per week. You can then loosen the rules for weekends.

Repeating this process multiple times, in a 3:4- or 5:2 pattern, will make you ‘keto adapted’. You’ll be able to quickly switch between fat-burning and keto mode.

Clare makes it easy to add healthy carbohydrates and protein on non-fasting days.

Your healthy eating habits must be so well-ingrained that you are able to happily maintain your weight equilibrium.

Long-term, switching from 3 meals per day to 2 is a great way to make life easier.

It is the way I live my daily life. Clare doesn’t naturally look slim. Or I’d balloon. I need to be careful about my weight.

By sticking to a Mediterranean diet and skipping breakfast, and enjoying a delicious, protein-packed brunch instead, and occasionally fasting to make up for any excess, my weight and waistline are kept down without counting calories.

Fast800: The basics 

STAGE 1: RAPID WEIGHT LOSS

800 – 900 Cals per day, for 2-12 weeks. Add protein to increase to 1000 cals.

Eat at least 50g protein and less than 50g carbs a day — and you should lose 1-2kg per week.

STAGE 2: INTERMITTENT FEASTING

800 cals for four to five days consecutively per week. A portion-controlled, but less relaxed approach on nonfast days. Increases in protein from 60-80g. Try ‘time-restricted eating’ which sets your eating window at 12 hours each day (i.e. 8am-8pm).

STAGE 3 – MAINTENANCE

No calorie counting but monitor your weight. Mediterranean diet: 1g of protein for every 1kg body weight.
