    Dude get off the Troll Train,

    Just in case troll is serious

    Eat the calories given by MFP AT LEAST, and exercise, duh thats its nothing better than that no pills, no fasts, no magic powders
  • wow, the negativity on here is baffling. Why can't people just be nice?
    As for starting out on 500 calories a day, it is your choice. It wont kill you... but it might be more harmful than good to your weight loss. You may find that after eating 500 calories for two days that you have the urge to binge... which may cause weight gain, not loss. I would recommend eating 1200 calories a day to start, and try that for a month or two. But good luck! :)

    500 for breakfast is cool, then another 500 later...then more 500...and some more :smile:

    Troll post? uh no,not at all.

    There are plenty of diets which recommend detox before starting a diet plan.

    500 calories for 2 days...

    That should be okay
    Which is why you shouldn't do it since "detoxes" haven't been shown to be needed in peer reviewed clinical studies to encourage weight loss.

    I don't see ANY PROS to this.

    Unless you consider starving yourself to an early death a PRO?

    500 calories.. way too much.. how do you deflate your stomach eating that much.
  • I suggest you also run a marathon everyday to ensure you maximize tho 500 calories you have eaten!

    Yes! PERFECT :)

    Just curious...many people are saying the OP won't lose any fat from doing 2 days at 500 pounds. However, if her maintenance intake is 2000 calories (for example), wouldn't that put her at a 3000 calorie deficit...rendering her nearly a pound lost? I am not advocating that, but 2 days doesn't seem too extreme.

    but that wont automatically be fat lost...

    why? and i am not trying to be dense. I understand if people take laxatives, they will feel thinner and weigh less...but it will be ALL water loss (zero fat loss). But in this scenario, she is actually cutting her calories...so wouldn't her body go to her fat reserves to compensate?

    any weight loss is a mixture of fat, muscle and water. after 2 days, you are talking mainly water plus weight loss from there being so little actual food in her body.

    no, eating 500 cals for 2 days wouldnt do much long term harm, but theres just no need to do adopt unhealthy habits as a way to lose weight, when eating a reasonable deficit with some exercise will get you better results that are sustainable...
  • okay, the OP isn't talking about eating 500 calories a day for months...she is talking about two days. her hair won't fall out in two days...she won't be destined to an early grave in two days. I do agree with the poster who said it may lead to bingeing.

    There are no pros. It's a dumb idea and you are only setting yourself up to fail. Don't be foolish.

    Wow...lots of mean people on this thread! It is not unheard of to jumpstart a diet plan. This one is for only two days - people fast for longer than that - for diet and religious purposes. And I am assuming any medical issues are being taken into consideration before starting this. Now...my "two cents" is that you ensure you keep hydrated during this period. That's extremely important. Good luck and keep positive!

    smh, because common sense is severely lacking these days, people keep encouraging bad habits that lead to worse habits ie 500 calories x 2 days eventually leads to 500 calories x 7 days and on and on and on.

    The sad thing is people KNOW they shouldn't be eating so little, if there was anything even remotely ok about it other people would not come to a public forum to get 'confirmation' that the bad thing isn't really bad. They would instead just do it, see the positive effects and go on rather than looking for permission to enact a bad idea. But the little smart person deep inside, buried by all the thinspo, fashion models, size 000 jeans ideas, KNOWS its not a good idea so they come to places like these,..... and then try to play the butt hurt card when people slap them with reality.

    Difference between being nice and encouraging dumb behavior

    If the deficit is too large you will also break down muscle to use for energy, there is a limit to the amount of fat that can be released in a day.

    thank you for responding...but why wouldn't the weight loss consist of any fat loss?
  • How many posts are you going to make on this same topic? No, it's not healthy, and no, you're not going to get support for it. Quit asking.

    lol how many times have they asked?

    Lol OP has made 10 posts in total. 9 of them have asked the same question put differently each time, and, may I add, decreasing amounts of proposed calories to be eaten.

    Oh, I see. tumblr_inline_mudtzpKj6b1rhu5zk.gif

    Just for educational reasons im gonna venture here.... its actually very simple

    The first thing your body gets rid of is water its the easiest. most people see their weight go down because of water loss

    Second to go is Muscle, Muscle is much easier for your body to burn up for energy than fat. Hence the reason people advocate strength training and eating adequately primarily rather than eating a deficit and cardio. The goal is to preserve as much muscle as you can, Constantly breaking down your muscles through use and then feeding them to repair forces your body to burn fat. NOT eating 500 calories a day to make the number line up.

    LAST is Fat. your body wants to hang on to fat not burn it, even doing what she's doing her body would go to other sources first. Fat is meant to be the emergency stores like the dooms day bunkers people have, its the last resort, you dont use it unless there's no other option. FAT = DOOMS DAY BUNKER


    ETA: i'm not a nutritionist or trainer or phd in metaphysics etc, this is just what i believe I've learned and LITERALLY the only thing that makes sense

    Yea sure this 2 days wont kill her, but its not going to help either, will only sabotage any real results she could get by just starting off right to begin with.

    One can only burn a limited amount of fat per day and it's based on total fat mass. From her previous posts, it doesn't seem like she has much to lose meaning she may already be at an average or low level of fat mass as is. A simple calculation to determine the limit of energy transfer from fat stores is: total fat mass (lbs) x 31 calories. For example, let's say she has 30 lbs of total fat mass. Thus, her max deficit window whereby fat oxidation occurs is 930 calories below maintenance. If her TDEE is 2000, then fat oxidation will only occur by eating <2000 to 1070 calories. However, not all of this 930 calories will come from fat mass - some may indeed come from lean mass even if it's a small and insignificant amount. Any energy expenditure below this limit will come from sources other than fat stores. So if she only eats 500 calories for two days, then she will be under her limit by 570 calories each day whereby those calories will come from non-fat stores.

    thank you. I appreciate your explanation. also, do you determine fat mass by body fat measurements?

    Also, an answer like yours is very helpful, and I wish someone explained that to OP initially. because just telling someone it is a stupid idea doesn't hold a lot of weight (pardon the pun), but understanding why it is a bad idea (or at least not a good idea) is helpful. But apparently OP has posted similar posts, so maybe someone did explain this to her.

  • It won't hurt you, but the biggest risk is triggering a binge.

    Ill say this simply


    Rather shut up

    The OP isn't going to die from eating 500 calories for 2 days. But it very will likely end in a binge, probably before 2 days are over.

    And a 5 lb weight loss over a year makes you an expert?? Always amazes me how the "newbies" or those with little losses feel the need to offer up "expert" advice--sarcastic or not!

    Hahaha kristen youre so funny, :laugh:

    I'm not a newbie by any means, and you dont know my situation or my history over this past year or the year before. You dont know what my losses have or havent been, and whether or not I've had any medical setbacks.
    That being said I'm not about to justify to you why I feel I can say what I say, never mind that it makes total sense..... NICE try though .. you cant always trust how the numbers line up.... or maybe you missed that comment

    I believe the thread is addressing OP's question, not the losses, gains, 'newb' status, or history of the responders.

    But good on ya for losing 47lbs *high five*

    I'm only have 500 calories for 2 days, so is that okay?? Apparently muscle loss kicks in on day 3..

    No, that is not okay. It's unhealthy.

    What do you mean muscle kicks in the third day? Muscle is built from weightlifting at a surplus, not starving yourself for two days.

    It doesn't matter. Eating 500 calories a day is not healthy, it's drastic and unhealthy. That's is twice below anyone's BMR.

    Besides this, you starve yourself for two days, start eating normally, and then you gain it back. Where's the health in that?
