I’ve had loads of requests for a Quick 800 weight-reduction plan assessment. I had seen all the media headlines and the precise analysis when the primary 800 calorie weight-reduction plan research – DiRECT – got here out. I knew {that a} man named Michael Mosley had parlayed that analysis right into a weight-reduction plan that supposedly ‘reverses diabetes,’ however I had no thought how common that weight-reduction plan was really 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 every part I’ve discovered and skilled about weight reduction and diet. However what’s the Quick 800 weight-reduction plan all about, and is it actually that unhealthy?
Let’s have a look.
What’s the Quick 800 Eating regimen?
The Quick 800 is promoted by Dr. Michael Mosley, who just isn’t 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-reduction plan applications led by medical doctors or entrepreneurs like Dave Asprey have some type of ‘rags to riches’ well being story hooked up to them. That is all properly 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-reduction 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-reduction plan product with emotion, however I need 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 purple flag when anybody makes use of this time period to explain a persistent illness remission.
Followers of Quick 800 can select from three completely different ‘approaches’:
The Very Quick 800, which is an 800 calorie weight-reduction plan completed over 2-12 weeks. It’s for ‘individuals searching for fast weight reduction’, or to ‘reverse their diabetes.’ Followers of the Very Quick 800 are inspired to include fasting into this system as properly, though I’m undecided what a part of 800 energy a day is NOT fasting.
For the overall inhabitants, three months of 800 energy a day just isn’t protected or really useful by respected healthcare suppliers. 800 energy a day falls into the class of VLCD, or Very Low Calorie Eating regimen. If somebody must undertake this type of consuming plan, they need to be adopted intently by a medical workforce that features a physician and dietitian.
Quick 800 does give an exhaustive listing of who shouldn’t do this system. This consists of individuals underneath 18, pregnant or nursing ladies, anybody with an consuming dysfunction historical past, kind 1 diabetes or anybody on insulin, and individuals who have had a current coronary heart assault.
The New 5:2, which is an intermittent fasting program that has 800 calorie days twice per week. It’s for ‘gradual weight reduction’ and to ‘enhance total well being.’
Manner of Life, which is a lower-carb ‘upkeep’ plan.
The entire plans are reasonable to low-carb, and are styled after the Mediterranean weight-reduction plan. Which, FYI, is often not low in carbs.
Quick 800 analysis.
There have been a number of current research that put topics on an 800 calorie weight-reduction plan to look at the influence on their diabetes, danger for diabetes, and cardiometabolic danger elements.
In 2018, a analysis research referred to as the DiRECT trial put 68 out of 149 topics with kind 2 diabetes into remission utilizing weight-reduction plan alone. Weight reduction in 36 of the members was no less than 15kg. The trial was funded by Diabetes UK, lending it some credibility in scientific and diet circles.
Usually, these outcomes could be nice information. There are loads of kind 2 diabetics on the earth, and attaining remission from this persistent illness would little doubt enhance their high quality of life and their total well being, to not point out their illness danger.
Predictably, the DiRECT trial outcomes had been all around the media. However what the media didn’t emphasize was that the members within the research had been subjected to an 800 calorie liquid weight-reduction plan throughout 3-5 months. As in, you may put your diabetes into remission, however you’ll must starve your self first.
No thanks.
Following DiRECT, there was DROPLET, the same research completed on ‘obese individuals’ with BMI >30, that used an 800 calorie liquid weight-reduction 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 danger (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 among the weight was nonetheless stored off), and variations in cardiometabolic danger elements weren’t important between the 2 teams (aside 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 reasonable protein larger glycemic load weight-reduction plan.
Curiously, whereas members misplaced important weight, on the finish of three years, the incidence of kind 2 diabetes was decrease than researchers anticipated. As well as, there was no significance between the 2 teams.
Are we completed placing individuals on hunger diets, already?
Shedding 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 necessary to notice that the above trials had been medically supervised. Quick 800 just isn’t.
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-reduction plan, as a result of it could be tremendous triggering to me.
Step one after signing up was to finish a questionnaire to find out which weight-reduction plan strategy was really useful for me. As I stated above, I attempted to recreation the system by placing in a a lot decrease weight and a low weight objective – one thing fully inappropriate.
To the credit score of Quick 800, the app instantly advised me that due to my weight, this system just isn’t acceptable for me, and that I ought to request a refund. This was precisely what I needed to occur!
Curiously, I’ve tried the identical factor with different weight-reduction plan applications *ahem* Noom *ahem* and ended up getting a low calorie weight-reduction plan anyhow. Not okay.

I then went again and put in my precise weight and a objective, and since my anthropometrics are usually not indicative of excessive diabetes danger, the app gave me the Manner of Life strategy.
This ‘upkeep part’ plan supplied me between 1300 and 1600 energy a day, which is much decrease than what I want, however nonetheless not shockingly low (once more, see Noom). The app didn’t assume I wanted to shed some pounds, so presumably it thinks that this degree of energy will maintain me.
I imagine that the general public who use the Quick 800 are doing it to shed some pounds. I believe that almost all 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 interested by it.
There are meal plans and procuring lists and on-line communities and coaches (who aren’t dietitians) to help Quick 800 followers. I discovered the recipes to be pretty simple, with a great number of plant-based and animal proteins. Clearly although, for those who’re too busy to prepare dinner meals, otherwise you don’t have entry to all kinds of meals for no matter purpose, you’ll most likely have points with this weight-reduction 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 should trigger insulin resistance, which may result in diabetes.
He provides this rationalization:
If you’re not utilizing vitality successfully, and ceaselessly topping up with snacks, your pancreas releases extra insulin to attempt to deliver down your often peaking blood sugars. Over time, insulin receptors will grow to be resistant which means much less glucose is transferred to vitality cells and your blood sugar ranges stay excessive – that is typically the place to begin of kind 2 diabetes.10
He presents up this reference to help this concept. Besides that this paper doesn’t help it in any respect – it’s only a scientific assessment 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 gas turns into accessible to maintain your physique going, tiredness will kick in and starvation ranges will enhance as your mind tells you that extra vitality is required. Regardless of the intention, snacking really makes you hungrier and breaking out of this cycle is the important thing to stopping.
Nope. Telling folks that they will’t eat in the event that they’re hungry, and that snacks will end in insulin resistance for EVERYONE, isn’t productive. It’s this type of all-or-nothing pondering that’s a purple flag for me…particularly when there’s no proof to help it.
You may shed some pounds having snacks, and they don’t seem to be straight linked to insulin resistance. That is fully ridiculous, and means that though Mosley invented this weight-reduction plan, his data about diet and physiology may be very restricted.
That’s one other purple flag. A few of what he says is correct, different issues (and this complete weight-reduction plan usually) are actually, actually not. As knowledgeable, I’ll say that anytime this occurs, it leads me to mistrust what the individual says.

Mosley has confronted some critical backlash from selling this weight-reduction plan.
In 2021, he went on TV throughout Consuming Dysfunction Consciousness Week to advertise the Quick 800 for ‘dropping the lockdown weight.’
In 2020, he appeared on a UK morning present telling folks 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-reduction plan ‘burns fats by flipping a metabolic change.’
That is language utilized in advertising to make potential clients imagine that this weight-reduction plan is as simple 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 obtained 2000 complaints.
Individuals weren’t completely satisfied.
Mosley additionally had a TV present referred to as, ‘Lose a Stone in 21 Days,’ which actually appears like a scorching rubbish mess. As a result of though dropping that a lot weight in that wanting a time is likely to be doable (a stone equals 14 kilos or simply over 6 kilograms), really attaining it isn’t essentially a good suggestion.
Greatest Loser, anybody? Anybody?
And though the Quick 800 web site claims that there isn’t any proof that the weight-reduction 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 danger issue within the growth of an consuming dysfunction. The programme didn’t seem to take care of the members’ psychological well being in any approach, resembling consultations with a psychiatrist. Nonetheless, it did have an alarming give attention to the members’ weight, BMI and measurements, in addition to encouraging them to hold out actions that we all know these affected by consuming issues might interact in, resembling 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.
Not too long ago, 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 ladies – and once more, the backlash was swift.
Menopausal ladies (and other people usually) 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-reduction plan – and shouldn’t be including extra stress to their lives.
Whereas it’s true that our danger for insulin resistance will increase with menopause, it’s not a forgone conclusion that it’s going to occur – and VLCDs may end up in rebound overeating and weight-reduction plan biking, which analysis exhibits can really enhance well being dangers.
They will additionally trigger nutrient deficiencies, which might be why Quick 800 recommends nutritional vitamins to followers. Pink flag.
A current research revealed within the BMJ discovered the next than anticipated prevalence of consuming issues in ladies in midlife. Individuals 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-reduction plan as a simple and protected approach to shed some 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-reduction plan, and any improved bloodwork outcomes that folks may even see are possible as a consequence of weight reduction. This may be achieved with out going to such extremes.
VLCDs shouldn’t be completed with out the approval and oversight of a doctor. As a dietitian, I don’t advocate them, and by no means have. I see completely no level in taking energy down that low, which may 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 ladies are the brand new targets of fad diets, dietary supplements, and excessive weight reduction applications, together with this one. I’ve stated in as soon as, and I’ll say it once more: no one must eat solely 800 energy to be able to shed some pounds.
Is weight-reduction plan soda unhealthy? Right here’s what the analysis says.
It is best to by no means must take dietary supplements to ‘make up’ for what your weight-reduction plan plan isn’t supplying you with. Should you’re on a weight-reduction plan that’s that restrictive, it’s a purple flag.
Lastly, shedding weight themselves doesn’t make somebody a weight-reduction plan knowledgeable. In the event that they’re promoting a product related to that weight reduction, be very suspicious.
