Starvation Mode

I know there is a camp of people who don't "believe in starvation mode" and I would like to politely ask those people not to join this conversation :) Thanks!

I have a very heat sensitive body and when it is as hot as it has been (90-100 degrees F) I just can't eat. I log everything that goes in my mouth besides water and yesterday I only got to 750 calories. I couldn't have shoved any more in. It's been like that for a few days and it looks like the weather is not changing for at least two weeks. So, here are my questions: how long does it actually take to get into starvation mode (I'm at 244lbs if it matters) and do you actually get into starvation mode if you don't feel starved?

    The term stavation mode is not a great way to describe what happens to the body, basically in "starvation mode" you metabolism slows down due to lack of calories consumes and stores more because it doesnt know when its next meal is going to be. The body is design to keep you alive so during the time of famine will try and hold on to calories to keep you alive.

    As to how long this takes it varies from person to person. However it can takes weeks or months of sustained under eating for your body to slow down, one or two days arnt going to do any harm but just try and not make a habit of it.

    At 244 lbs it's unlikely you'll ever be in what you consider starvation mode.

    So is that a fat joke or are you saying that larger people can't be in starvation mode?

    No it's not a joke. You should be more worried about insulin resistance at your current weight than something that only exist in the land of goblins, trolls, and fairy tales.

    Months and years of undereating can lead to issues with your metabolism, it did for me. It may not be called "starvation mode" but I gained weight eating at a deficit because my body was overworked and underfed.

    Eventually your body will want to eat more food, just do so when you are ready. I'm not sure a few weeks will really do you harm. But i would try to eat more if you can.

    I dont think it was a joke, I think he point he was trying to make albit crudley it that the higher the bf% the harder it is for the metabolism to slow, because Fat is a source of fuel and will be used as such. Like I said early it will take months of under eating to slow it down, and by that point your body will have used a vast amount of your BF!

    Wow, I don't know if this person meant to come off mean and snotty but just, WOW. You'd think on a site like this people would be a little more sensitive.

    I honestly don't know if there is such a thing as starvation mode. However, I do know for myself, if I don't eat all of the calories available to me, including my exercise calories, after a few days I start binging like crazy. It's like my body is telling me "Hey, you're not feeding me enough so I'm just gonna eat whatever the heck I want and lots of it so it doesn't happen again."

    According to the above poster, I would be too fat to actually starve but my body feels that way. You have to listen to yours. Trying eating more calorie dense foods like peanut butter, protein shakes and bars to get the calories in without feeling like you are stuffing yourself but still get the calories and more importantly, some nutrition in.

    There are documented instances of obese humans undergoing medically supervised fasting for over a month with only water and multivitamins being consumed. Take from that what you will.

    You have to under eat for several months to damage (or lower) your metabolism.. I wouldn't worry about a few days.. but you should still work on getting your calories up.

    Generally people don't make fat jokes on this board. It would kinda be an *kitten* thing to do. I'm assuming that poster was getting at the fact that since you have an abundance of healthy fat reserves, you body won't drop your metabolism into "starvation mode" until your bodyfat percent is down quite a bit.

    Reading you post I was reminded of a man in (England I think) who, under a doctors supervision, ate NOTHING for a whole year but water and vitamins.

    750 calories isnt enough everyday, but if you do that occasionally I don't think you have to worry about starvation mode. And since you don't feel hungry, no problem. I will say your brain does need carbs to function, just keep that in mind.

    Thanks for the responses guys :) I'm was really scared about that! I have lost 30lbs since April and have heard about people stalling their weight loss after even a week of low calories... I was hoping that wasn't true and it sounds like it isn't :)

    While it's hot you could try to eat more calorie dense foods like cheese, peanut butter, nuts, etc. It will help you get closer to your goal without making you feel as if you're force feeding yourself.

    It was not a fat joke. Shifts in ones metabolism is broken into two basic parts. The first change is simply the result of one losing weight. That should be straight forward. Weigh less, require less. The second change is referred to as the adaptive component. That metabolic shift tends not to have much effect until one is at lower BF levels. Read the Minnesota study if you like on this topic.

    From what you described I would be more concerned about what effect you are having on your hormones (grhelin, leptin, thyroid...). Our bodies like to be fat, and tend to throw up road blocks to hold on to fat by adjusting different hormone levels. Those hormones affect the release of fat for use. Some of us have more difficulty than others.

Like I said early it will take months of under eating to slow it down, and by that point your body will have used a vast amount of your BF!

    I was reading today that a woman doesn't even have to begin to worry about starvation mode unless she's 10% body fat (and of course there are elite women athletes at that percentage). As you said, people only have problems if they are eating severely low-calorie meals (much less than 750) for weeks or months and are low-weight.

    When people talk here about the "myth" of starvation mode, they don't mean that it never happens, only that the people who are anxious about it are nowhere near a weight where this could ever be a problem. Their worries are misplaced.

    If you have the stomach for it, watch the movie "The Hunger," about an Irish political prisoner who goes on a hunger strike. He starves to death because he eats absolutely nothing and refuses all nourishment, including liquids. Although the character is a thin man, even he doesn't starve overnight. It takes at least a couple of months.

    It's just not healthy to eat 700 calories. This will deffinitly slow down your metabolism, making your body store fat. Plus, if you're working out then you won't even have any energy. AND you will lose your precious muscle too! :( And it's sooo much harder to gain muscle then lose fat.
    What about making yourself a shake to drink during hot days?? It's much easier then making yourself eat food. I like to make my shakes with almond milk, ice, protein powder, frozen kale, frozen berries, flex or chia seed. Try it! very refreshing, healthy and filling.

    Can I also suggest you take cool baths to be more comfortable and make it easier to eat? And plan to eat a meal after 10 when it is cool?

    I eat much less in the summer than winter. It is actually not unusual for me to net under 1000 calories (or less) in the summer. Last week I was a whole day's worth of calories short. In the winter, it's cold and I want to eat more.

    I lose more in the summer than the winter. No slowing of metabolism - it seems faster, actually.

    But I really recommend eating your higher calorie meal LATE in the day and early in the morning, as they do in most countries where it is blazing hot.

    I'm sorry, but I didn't want the chain of "it's not real," "it's not real," "it's not real" that I've seen before :)

    Please read this. It's under the "Read this first newbies" section of this forum (which no one bothers to read). Yes, your metabolism can slow dramatically EVEN IF YOU ARE OVERWEIGHT:

    Adaptive thermogenesis will slow down her metabolism so much that she will have fat gain at 700 cals?

    I think "starvation mode" is a poor term. Metabolic Damage may be a better way to describe it. I wouldn't say you'd have to worry about that right now. However, as others have mentioned, hormones would be your biggest concern at very low calories for extremely long periods of time.

    Yeah, we really have a HUGE problem in society regarding starvation mode... that is the BIG issue- not obesity... thanks for keeping our priorities clear.

    Metabolic adaption is a better term. People who have done true damage to their bodies are diabetics.

    No such thing as starvation mode. It's just a slow metabolism. I was at a point in my dieting where I wasn't losing weight eating 1200 calories and burning 500 calories. I know, I was an idiot. When I added a refeed day, I suddenly started dropping again.

    I have those days too when I just can't eat anymore... I'm either full or not hungry at all. To help get some extra calories in, use extra virgin olive oil when cooking, eat nuts or avocado... High (good) fatty foods will help you with calories but not jeopardize your health... just be wary on the nuts. Some of them can have a lot of cholesterol.
  • Yeah I would not worry about it love. At 244lb if you are in a deficit you may start bumping out some Fatty acids into your blood stream, maybe even some mild ketosis, which will be a good thing and protect your muscles form excessive breakdown.

    Yes your metabolism will go down when you don't eat, because eating increases your metabolism, because energy is required to break down the food and then get a net gain. Protein breakdown from food into energy (amino acids --> sugars) is the most wasteful metabolism spiking eating habit, at 25% of the energy gained is used to break down the macronutrient in the first place, so even with this metabolism 'spike' you will still gain three calories for each gram.

    As others have said, it probably does not do any harm short term, however it may cause you to have psychological and limited physiological urges to binge in the next couple of days. Avoid the temptation.

    No, sorry if it came off that way.:flowerforyou: But yes, when someone has a lot of body fat the oxidation from that body fat more than covers most deficits, even severe ones. There is an adaption that can effect our metabolism but it's pretty small in comparison to most deficit, unless it's a very small deficit, like 10% where the weight loss lowers metabolism to match that new weight, anyway there should never be a plateau basically...........that's more of a miscalculation of the in/out numbers.
