Huge deficit

Posts: 592 Member
edited December 2024 in Health and Weight Loss
So, hypothetical.

Imagine someone went on one of these 800 calorie a day diets, they walked there 10,000 steps (500 cal) plus they went jogging or cycling for a further 1300 calories.
That would be a deficit of 3500 calories a day a 1lb in weight.

I wonder what impact this would have on the person.
Consider the 800 calories contain all vitamins and minerals needed.

Has anyone any idea ?

    I think this should be the label on all 800 calorie diets.

    Is the NHS promoting 800 calorie diets for everyone, or people with specific medical conditions who are under strict medical supervision?

    While click-baity headlines may imply the former, the truth is probably the latter.

    See also from the NHS https://www.nhs.uk/live-well/healthy-weight/very-low-calorie-diets/ the media's interpretation of stuff, often isn't quite what is intended to be put across.

    Edited for TLDR:

    Excerpt
    "VLCDs aren't suitable for most people
    VLCDs aren't routinely recommended by the NHS unless a patient has a medical need, such as needing to lose weight:

    *for surgery
    *to help manage a health condition, such as diabetes
    *to prepare for fertility treatment"

    So the NHS in England are promoting these 800 calorie diets.

    Actually, no, they aren't -- they are using them in very limited situations with severely overweight and obese type 2 diabetics, with intense medical monitoring.

    Aren't those also very highly supervised diets though. As in, the patient is working very closely with their doctor(s) and has to meet various qualifications in order to qualify. They aren't suggesting that the whole of the country go on that diet.

    I can't even imagine an 800 cal. diet that wasn't an absolute medical necessity.

    I was thinking the same thing. With my occasional hangry feelings at my current deficit... and admitedly I can get hangry while on maintenance... I’d turn into a crazy person on 800 a day. That or I’d turn into a wraith. Or an axe murderer.

    Haven't read all reply..

    Vitimins has very little to no calories at all. body needs fuel from calories.
    800 cal? Unless your on the survival show (naked and afraid). You'll look like them in the end.. frail and week.

    HA! No kidding right?

    I do understand the attraction of and desire to have a hypothetical discussion, but I've known people with severe eating disorders (my niece is one) and my immediate reaction is just 100% push back against the idea. Most folks (I would think) want to lose weight to gain health and look good. 800 cals per day accomplishes neither of those goals.

    You are absolutely right. A woman I went to college with was hospitalized because of her eating disorder. Twenty years later she is still super lean, but strong - I see her occasionally at the gym, which is why I know.

    People get impatient because they want to lose weight, but there are so many health-related reasons for moderation. Sometimes I feel I am borderline obsessed with tracking my weight and calories these days, but I’ve also yoyo-ed for most of my adult life and want to learn the maintenance thing. It’s all about moderation -800 calories is extreme

    My desire to discuss it was because,
    I'd read the NHS were promoting such diets to anyone with a BMI over 30, (it seems that it maybe media hype) so my questions were because I wondered what the issues might be if I chose to go on this diet. My BMI is 31 and I run 3 to 4 times a week.

    I've just looked at this article and there is a section in it that asks that you see if the 800 cal diet is suitable for you. It told me that my BMI is 33.4 [which I know] and that I could see my doctor with a view to going on the diet. It also said if I was already on a weight reduction plan to stay with it. However, it did not ask me whether I was either pre -diabetic or diabetic. In fact I am neither and will carry on with MFP.

    Oh - I wasn't "targeting" you with that. Just "verbalizing" my own response. I have a tough time discussing things without bias that I have a strong personal bias against, that's all.

    When I saw the "promoting" I was a little shocked myself.

    To be fair, the calculator is from the BBC, not the NHS. And the calculator does say you should only do the diet for 12 weeks or once you reach a BMI of 25, whichever comes sooner.

    I think it also bears mentioning this 800 cal diet is not just someone eating 800 cals. It is obtaining a liquid meal replacement diet program. I would assume this is to make sure there is proper nutrition included in that 800 cals.

    Regardless, anything I'm seeing that is direct from the NHS is saying, their data "seems" promising and they think it's worth it for obese folks with diabetes to consult a doctor regarding the program. It is media outlets that seem to be directing it toward anyone with a specific BMI.
