I’ve had loads of requests for a Quick 800 weight loss plan evaluate. I had seen the entire media headlines and the precise analysis when the primary 800 calorie weight loss plan research – DiRECT – got here out. I knew {that a} man named Michael Mosley had parlayed that analysis right into a weight loss plan that supposedly ‘reverses diabetes,’ however I had no thought how well-liked that weight loss plan was truly going to get.
And the way a lot press it was going to obtain.
800 energy a day. As a dietitian, it goes in opposition to all the pieces I’ve discovered and skilled about weight reduction and diet. However what’s the Quick 800 weight loss plan all about, and is it actually that unhealthy?
Let’s have a look.
What’s the Quick 800 Weight loss program?
The Quick 800 is promoted by Dr. Michael Mosley, who shouldn’t be a licensed doctor – he’s a journalist and TV presenter. He did qualify as a psychiatrist, however hasn’t been working as an MD since 1985.
Mosley has been credited for inventing 5:2 fasting, having adopted this fashion of consuming and apparently therapeutic his personal well being points.
I discover loads of weight loss plan packages led by docs or entrepreneurs like Dave Asprey have some form of ‘rags to riches’ well being story hooked up to them. That is all nicely and good, however somebody’s story doesn’t imply sh*t when utilized to your personal well being.
In different phrases, simply because Michael Mosley used this weight loss plan to ‘reverse’ his diabetes doesn’t imply that this fashion of consuming is simple or good. Private anecdotes are sometimes used to promote a weight loss plan product with emotion, however I would like you all to watch out about falling for this.
I put quotes across the phrase ‘reverse,’ since diabetes goes into remission..it doesn’t ‘reverse.’ The phrase ‘reverse’ implies a ‘remedy,’ which isn’t potential. It’s a crimson flag when anybody makes use of this time period to explain a power illness remission.
Followers of Quick 800 can select from three totally different ‘approaches’:
The Very Quick 800, which is an 800 calorie weight loss plan finished over 2-12 weeks. It’s for ‘individuals in search of fast weight reduction’, or to ‘reverse their diabetes.’ Followers of the Very Quick 800 are inspired to include fasting into this system as nicely, though I’m undecided what a part of 800 energy a day is NOT fasting.
For the final inhabitants, three months of 800 energy a day shouldn’t be protected or really helpful by respected healthcare suppliers. 800 energy a day falls into the class of VLCD, or Very Low Calorie Weight loss program. If somebody must undertake this form of consuming plan, they need to be adopted carefully by a medical workforce that features a physician and dietitian.
Quick 800 does give an exhaustive checklist of who shouldn’t do this system. This contains individuals below 18, pregnant or nursing girls, anybody with an consuming dysfunction historical past, sort 1 diabetes or anybody on insulin, and individuals who have had a latest coronary heart assault.
The New 5:2, which is an intermittent fasting program that has 800 calorie days twice every week. It’s for ‘gradual weight reduction’ and to ‘enhance general well being.’
Approach of Life, which is a lower-carb ‘upkeep’ plan.
All the plans are average to low-carb, and are styled after the Mediterranean weight loss plan. Which, FYI, is usually not low in carbs.
Quick 800 analysis.
There have been a number of latest research that put topics on an 800 calorie weight loss plan to look at the impression on their diabetes, threat for diabetes, and cardiometabolic threat elements.
In 2018, a analysis research known as the DiRECT trial put 68 out of 149 topics with sort 2 diabetes into remission utilizing weight loss plan alone. Weight reduction in 36 of the contributors was no less than 15kg. The trial was funded by Diabetes UK, lending it some credibility in scientific and diet circles.
Usually, these outcomes can be nice information. There are loads of sort 2 diabetics on the planet, and reaching remission from this power illness would little question enhance their high quality of life and their general well being, to not point out their illness threat.
Predictably, the DiRECT trial outcomes had been everywhere in the media. However what the media didn’t emphasize was that the contributors within the research had been subjected to an 800 calorie liquid weight loss plan at some point of 3-5 months. As in, you’ll be able to put your diabetes into remission, however you’ll need to starve your self first.
No thanks.
Following DiRECT, there was DROPLET, the same research finished on ‘chubby individuals’ with BMI >30, that used an 800 calorie liquid weight loss plan for 8 weeks, adopted with meals re-introduction. The topics on the 800 calorie plan misplaced extra weight and noticed extra enhancements than the management group in biomarkers of metabolic and cardiometabolic threat (HbA1C, ldl cholesterol, blood strain, and many others.) However at the 3-year follow-up, intervention group weight achieve was greater than the management group (however a number of the weight was nonetheless saved off), and variations in cardiometabolic threat elements weren’t important between the 2 teams (apart from blood strain).
In 2020, the outcomes from one other research, the PREVIEW intervention research, had been revealed within the journal Diabetes, Weight problems, and Metabolism.
PREVIEW had 2326 pre diabetic adults randomized to both a excessive protein medium glycemic load, or average protein larger glycemic load weight loss plan.
Curiously, whereas contributors misplaced important weight, on the finish of three years, the incidence of sort 2 diabetes was decrease than researchers anticipated. As well as, there was no significance between the 2 teams.
Are we finished placing individuals on hunger diets, already?
Losing a few pounds does typically enhance blood glucose, blood strain, ldl cholesterol, and different metrics. However the stress of consuming virtually nothing for weeks on finish, after which transitioning to a 5:2 fasting routine, is one thing solely a really small section of the inhabitants can bodily abdomen. And even then, what’s it doing to their relationship with meals and their our bodies?
It’s essential to notice that the above trials had been medically supervised. Quick 800 shouldn’t be.
I made a decision to join the Quick 800 to essentially see what it’s all about (and to see if I might recreation the system). I didn’t do the weight loss plan, as a result of it might be tremendous triggering to me.
Step one after signing up was to finish a questionnaire to find out which weight loss plan method was really helpful for me. As I stated above, I attempted to recreation the system by placing in a a lot decrease weight and a low weight aim – one thing fully inappropriate.
To the credit score of Quick 800, the app instantly instructed me that due to my weight, this system shouldn’t be applicable for me, and that I ought to request a refund. This was precisely what I wished to occur!
Curiously, I’ve tried the identical factor with different weight loss plan packages *ahem* Noom *ahem* and ended up getting a low calorie weight loss plan anyhow. Not okay.

I then went again and put in my precise weight and a aim, and since my anthropometrics will not be indicative of excessive diabetes threat, the app gave me the Approach of Life method.
This ‘upkeep part’ plan provided me between 1300 and 1600 energy a day, which is much decrease than what I would like, however nonetheless not shockingly low (once more, see Noom). The app didn’t assume I wanted to shed extra pounds, so presumably it thinks that this degree of energy will maintain me.
I consider that most people who use the Quick 800 are doing it to shed extra pounds. I think that the majority of them will obtain the Very Quick 800 plan as their first step.
‘Starve the fats individuals,’ if you’ll. I really feel a bit sick fascinated with it.
There are meal plans and buying lists and on-line communities and coaches (who aren’t dietitians) to help Quick 800 followers. I discovered the recipes to be pretty straightforward, with a very good number of plant-based and animal proteins. Clearly although, for those who’re too busy to cook dinner meals, otherwise you don’t have entry to all kinds of meals for no matter purpose, you’ll in all probability have points with this weight loss plan.
There are no snacks in any respect in any of the plans, as a result of Mosley tells us that snacks ‘make us hungrier’ and will trigger insulin resistance, which might result in diabetes.
He offers this clarification:
If you’re not utilizing power successfully, and continuously topping up with snacks, your pancreas releases extra insulin to try to carry down your recurrently peaking blood sugars. Over time, insulin receptors will turn out to be resistant that means much less glucose is transferred to power cells and your blood sugar ranges stay excessive – that is typically the place to begin of sort 2 diabetes.10
He affords up this reference to help this concept. Besides that this paper doesn’t help it in any respect – it’s only a medical evaluate of insulin as a hormone. It confirms what we already know – that insulin resistance can result in diabetes, however nowhere within the paper does it speak about snacks.
He goes on to say this:
As much less gasoline turns into obtainable to maintain your physique going, tiredness will kick in and starvation ranges will improve as your mind tells you that extra power is required. Regardless of the intention, snacking truly makes you hungrier and breaking out of this cycle is the important thing to stopping.
Nope. Telling those that they will’t eat in the event that they’re hungry, and that snacks will lead to insulin resistance for EVERYONE, isn’t productive. It’s this form of all-or-nothing considering that’s a crimson flag for me…particularly when there’s no proof to help it.
You’ll be able to shed extra pounds having snacks, and they don’t seem to be instantly linked to insulin resistance. That is fully ridiculous, and means that though Mosley invented this weight loss plan, his information about diet and physiology could be very restricted.
That’s one other crimson flag. A few of what he says is correct, different issues (and this complete weight loss plan normally) are actually, actually not. As an expert, I’ll say that anytime this occurs, it leads me to mistrust what the individual says.

Mosley has confronted some severe backlash from selling this weight loss plan.
In 2021, he went on TV throughout Consuming Dysfunction Consciousness Week to advertise the Quick 800 for ‘shedding the lockdown weight.’
In 2020, he appeared on a UK morning present telling those that after three or 4 days of consuming 800 energy, the abdomen ‘shrinks’ (that is unfaithful – the abdomen doesn’t shrink) and we ‘go into fat-burning mode.’
Why do individuals proceed to name ‘ketosis,’ ‘fats burning mode’? He additionally says the weight loss plan ‘burns fats by flipping a metabolic change.’
That is language utilized in advertising to make potential prospects consider that this weight loss plan is as straightforward as turning on a lightweight. It isn’t.
The response of many individuals on social media to each appearances was overwhelming outrage. The tv station that aired the 2021 section received 2000 complaints.
Folks weren’t pleased.
Mosley additionally had a TV present known as, ‘Lose a Stone in 21 Days,’ which truthfully seems like a scorching rubbish mess. As a result of though shedding that a lot weight in that in need of a time may be doable (a stone equals 14 kilos or simply over 6 kilograms), truly reaching it isn’t essentially a good suggestion.
Greatest Loser, anybody? Anybody?
And though the Quick 800 website claims that there isn’t any proof that the weight loss plan causes consuming issues, BEAT, a UK consuming dysfunction charity, gave an official assertion after Mosley’s ‘Lose a Stone’ present aired. It included the next paragraph:
Analysis has proven that dietary restraint, together with the restriction of energy, has been discovered to be a threat issue within the growth of an consuming dysfunction. The programme didn’t seem to take care of the contributors’ psychological well being in any means, comparable to consultations with a psychiatrist. Nonetheless, it did have an alarming concentrate on the contributors’ weight, BMI and measurements, in addition to encouraging them to hold out actions that we all know these affected by consuming issues could interact in, comparable to destroying meals to keep away from consuming it or fixating on consuming a restricted variety of energy.
The charity additionally reported a 51% uptick in calls on their helpline after the present aired.
Just lately, GP and menopause specialist Louise Newsom had Mosley and his spouse and fellow Quick 800 developer Clare Bailey, on her podcast for a chat. Throughout that episode, Mosley promoted Quick 800 to menopausal girls – and once more, the backlash was swift.
Menopausal girls (and other people normally) ought to by no means starve themselves. The truth is, in midlife and past, individuals have elevated protein wants to forestall muscle loss aka sarcopenia – one thing that’s more likely to occur with an 800 calorie a day weight loss plan – and shouldn’t be including extra stress to their lives.
Whereas it’s true that our threat for insulin resistance will increase with menopause, it’s not a forgone conclusion that it’s going to occur – and VLCDs can lead to rebound overeating and weight loss plan biking, which analysis reveals can truly improve well being dangers.
They’ll additionally trigger nutrient deficiencies, which might be why Quick 800 recommends nutritional vitamins to followers. Crimson flag.
A latest research revealed within the BMJ discovered a better than anticipated prevalence of consuming issues in girls in midlife. Folks in positions of authority – like self-proclaimed ‘menopause specialists’ – ought to by no means be selling diets like Quick 800.
A dietitian’s final phrase: The Quick 800.
The Quick 800 builders shouldn’t be promoting this weight loss plan as a simple and protected approach to shed extra pounds. It’s unnecessarily excessive, and there’s one thing unsavoury in regards to the undertone of telling fats individuals to starve themselves to be more healthy. I don’t prefer it.
Fasting isn’t higher than regular caloric restriction. Quick 800 is a low-calorie weight loss plan, and any improved bloodwork outcomes that folks might even see are probably resulting from weight reduction. This may be achieved with out going to such extremes.
VLCDs shouldn’t be finished with out the approval and oversight of a doctor. As a dietitian, I don’t suggest them, and by no means have. I see completely no level in taking energy down that low, which might result in rebound overeating, meals obsession, and nutrient deficiencies, particularly for those who’re doing it for months on finish. 800 energy a day is disordered consuming, for my part.
Menopausal girls are the brand new targets of fad diets, dietary supplements, and excessive weight reduction packages, together with this one. I’ve stated in as soon as, and I’ll say it once more: no person must eat solely 800 energy so as to shed extra pounds.
Is weight loss plan soda unhealthy? Right here’s what the analysis says.
You must by no means need to take dietary supplements to ‘make up’ for what your weight loss plan plan isn’t providing you with. Should you’re on a weight loss plan that’s that restrictive, it’s a crimson flag.
Lastly, reducing weight themselves doesn’t make somebody a weight loss plan professional. In the event that they’re promoting a product related to that weight reduction, be very suspicious.
