    There was a very interesting thread on reddit about this once. I saw a story there that stuck with me, but of course I can't find it now. Here's a paraphrase.

    The poster was a woman who was heavier than her boyfriend, who was a "naturally thin" person. One day she discovered a package of candy bars in his cupboard. After several subsequent visits over many weeks, she noticed that the candy bars were untouched. Perhaps one had been removed from the packaging.

    Unable to understand what was going on, she finally asked him about it. "Don't you like those candy bars?", she asked. They've been sitting there for weeks. "They're my absolute favorite," said the boyfriend.

    The poster had an epiphany. The boyfriend didn't feel compelled to eat all of the candy bars, as she would have been. He liked the candy, and ate it on occasion, but didn't desire to eat all of them up right away. The poster felt that, if she had a package of her favorite candy bars in her house, that they would be gone in a very short time. She realized that he was "naturally thin" in part not because he never ate candy, but because he didn't feel compelled to eat it all the time.

    Yup. That's my wife. No chocolate is safe with her, and oaths that she'll eat it a little at a time mean nothing. A pint of ice cream? Gone in a half hour, with no awareness at all that it consisted of 4 servings. The idea that is should be possible to treat oneself in moderation is understood by her on an intellectual level, but it doesn't penetrate to actual behavior.

    Yeah. I can keep ice cream around for months. I lived with my grandmother for a month and I'd buy ice cream to eat when I got home. (Label it with my name and everything) and she'd eat it.

    Hah, that is my husband. A treat I like once in a while is a certain brand of chocolate chip cookie. I can buy a package and eat one. Then I put it in the cupboard and go back the next day. All the cookies are gone. Husband can't stop eating cookies until the cookies are gone. Obviously, we don't buy cookies anymore.

    With me it is potato chips. If the bag is opened (no matter what the size) I have no ability to stop eating them. I may be able to have an unopened bag in the house for a day or two, but then I will stumble and open it. So no potato chips in the house. Husband doesn't mind too much because he is happy with tortilla chips as a snack, and I don't often eat corn chips, so that works for him.

    My husband does this for me. I'm a diabetic and having to live in the same house with certain sweets I can't handle anymore (such as chocolate chip cookies) is stressful, but fortunately I'm indifferent to pies, and he loves them. He also likes Pringles and Pop Tarts which don't even strike me as food. Sometimes I get a crazy carb craving and take a bite of his Pop Tart, and one bite is enough to remind me that I hate Pop Tarts. Now if we could work out a similar solution to bread, everything would be peachy - since I haven't been able to eat it (and I really can't, even a small piece spikes my blood glucose levels) I can smell bread all the way across the house. But I can't expect him to give up bread, I just have to deal.

    I love Pop Tarts, but they have to be unfrosted. I see no point in putting a sugary glaze on top of something that's already that sweet.

    Just a reminder that 'naturally thin' does not mean healthy or even low body fat - internal organs can be covered in unhealthy yellow fat (visceral fat) and the MONW (Metabolically Obese Normal Weight) person doesn't appear to be 'fat.' American Journal of Clinical Nutrition: ajcn.nutrition.org/content/34/8/1617.short
    National Institutes of Health: https://ncbi.nlm.nih.gov/pmc/articles/PMC3610876/

    Another thing to think about is that some 'naturally thin' people may have a higher proportion of brown adipose tissue to white/yellow fat. BAT actually burns calories when stimulated.

    There is not necessarily a direct relationship between a higher than average TDEE/NEAT and being "naturally thin".

    Since starting calorie counting in 2015, I've learned that I can eat around 30% more calories than the average for my age/weight/activity level. I don't know why.

    Despite that, I've spent most if my adult life obese. Why? I ate and drank more than my high TDEE.

    When I compare my ungoverned behavior to that of friends who've always been slim, I perceive that they stop eating at a point where I'd happily keep going, and historically did.

    A high TDEE/NEAT, by itself, isn't enough to keep someone thin. It's only a few hundred calories, and a few hundred from unknown metabolic factors is as easy to out-eat as a few hundred from exercise.

    My mum recently bought a box of bitesize flapjacks from asda and they were the most delicious flapjacks I have ever tasted. They were pretty much just square inches of butter and golden syrup held together with a few oats.

    I'm "naturally thin" and when I had the flapjacks I ate them slowly to savour every tiny bite and I only had two flapjacks a day. My overweight parents on the other hand ate each flapjack in two bites and definitely had more than two a day at because the box of 26 only lasted about three days. We agreed never to get the flapjacks again.

    My "naturally thin" sister didn't touch them at all because she doesn't like flapjacks.

    I think naturally thin can mean different things. As a small framed person, I need more calories per pound of bodyweight than someone who is 75 pounds heavier (assuming equal activity level). I've also always been thin my entire life.

    "Naturally thin" people have common traits. They just don't eat more than they need to.

    Well, obviously they don't eat more than need to. I don't think anyone is questioning that. The question was, do some people eat more than should need to and not gain weight. Do they eat more than would make the majority of other people of the same size, shape, sex, everything gain weight.

    The answer is yes. Absolutely yes. But not commonly yes.
    If they AREN'T gaining weight, then they aren't overeating regardless of their size, shape, etc. Lots of people can eat lots and not gain weight because they just have more efficient metabolisms than others of the same stature.

    Anecdote from a naturally thin person:

    In high school I ran a lot and ate homecooked meals. My "naturally thin" body took care of the occasional junk I fed it. Take away the running and add lots more junk food... of course I gained about 30% of my body weight pretty quickly and have been struggling to lose it ever since.

    A former colleague was naturally thin, a luge long athlete, track team in high school, distance runner. Ran every day at lunch.
    Died of cardiac arrest at the age of 31 a few hundred yards from the finish line of a half marathon.

    No, I think the OP thinks calories are processed differently by the individuals.
    That would be a no. In general, if there's no health issue involved, people eat, digest, and then absorb macros and nutrients all the same way.

    So?

    Given that he was exercising and normal weigh he most likely lived longer with the poor hand he was dealt regarding his heart genetics vs someone that was fat and lived on the couch.

    Another characteristic of 'naturally thin' people is they tend to be active even when sedentary - they wriggle, fidget, and make hundreds of small movements while the overweight person sitting next to them is completely still. Start watching your 'naturally thin' friends while they're watching TV - How many times do they change position? Do they wave their arms about when they talk? Are they jiggling their foot? Do they get up often to make tea or grab something?.

    I took some time away from this post and watched my husband, who is one of these "naturally thin" folks I speak of....he moves a lot. At work he takes the stairs, is always moving his feet, etc. It was interesting.

    "Naturally" being more inclined to be active, or to eat less, is still not the same as being "naturally thin" as most people use it.

    Yes, my question was if calories could be processed differently. But what I am reading is that it could be because they have a more efficient metabolisms? So does that mean they are using the calories differently?

    There was a very interesting thread on reddit about this once. I saw a story there that stuck with me, but of course I can't find it now. Here's a paraphrase.

    The poster was a woman who was heavier than her boyfriend, who was a "naturally thin" person. One day she discovered a package of candy bars in his cupboard. After several subsequent visits over many weeks, she noticed that the candy bars were untouched. Perhaps one had been removed from the packaging.

    Unable to understand what was going on, she finally asked him about it. "Don't you like those candy bars?", she asked. They've been sitting there for weeks. "They're my absolute favorite," said the boyfriend.

    The poster had an epiphany. The boyfriend didn't feel compelled to eat all of the candy bars, as she would have been. He liked the candy, and ate it on occasion, but didn't desire to eat all of them up right away. The poster felt that, if she had a package of her favorite candy bars in her house, that they would be gone in a very short time. She realized that he was "naturally thin" in part not because he never ate candy, but because he didn't feel compelled to eat it all the time.

    Yup. That's my wife. No chocolate is safe with her, and oaths that she'll eat it a little at a time mean nothing. A pint of ice cream? Gone in a half hour, with no awareness at all that it consisted of 4 servings. The idea that is should be possible to treat oneself in moderation is understood by her on an intellectual level, but it doesn't penetrate to actual behavior.

    Ya, my brother has no concept of serving sizes. But there isn't a lot of calorie dense food in his and mom's house, and she hides the chocolate and doles it out. Either he doesn't have much of a sweet tooth or the fruit available satisfies it. And he's active, so with the food available at mom's has maintained a healthy weight for years without much conscious effort on his part.

    Most people are pointing out that "naturally thin" people are more active and not tempted to finish off the bag if favorite junk food as fast. Or overeat on non special occasions.

    Well, obviously they don't eat more than need to. I don't think anyone is questioning that. The question was, do some people eat more than should need to and not gain weight. Do they eat more than would make the majority of other people of the same size, shape, sex, everything gain weight.

    The answer is yes. Absolutely yes. But not commonly yes.
    If they AREN'T gaining weight, then they aren't overeating regardless of their size, shape, etc. Lots of people can eat lots and not gain weight because they just have more efficient metabolisms than others of the same stature.

    And that was the OP's question.
    No, I think the OP thinks calories are processed differently by the individuals.
    That would be a no. In general, if there's no health issue involved, people eat, digest, and then absorb macros and nutrients all the same way.

    Yes, my question was if calories could be processed differently. But what I am reading is that it could be because they have a more efficient metabolisms? So does that mean they are using the calories differently?

    If they took more calories to do the same functions it wouldn't it mean they had a less efficient metabolism?

    But again, if there is a significant difference it's probably due to a medical condition. There are all sorts of GI and auto-immune disorders that can cause calories to not be absorbed properly.

    I think one factor a lot of people don't consider is that the endocrine function of someone who has never been overweight/obese is radically different than someone who is currently or formerly overweight/obese. Your body will try its best to keep you from killing yourself with food, and even if you end up losing weight later, many these changes persist. Partly because you never lose white adipose tissue, and it remains metabolically active even if you lose weight. Partly because homeostatic set-points get disrupted in a long-term manner. In extreme cases, this can result in a difference in BMR of ~30% or more between a normal person, and a formerly obese person. One of my formerly obese friends maintains weight at 1400 calories/day working out 6 days/week. A lot of people here would look at him and say "oh he must have bad genetics," but the reality is he has hundreds of pounds of deflated fat still hanging around his body, insulin and leptin issues, and while he is extremely healthy compared to pre-weight loss (the doctor told him he had maybe 2-3 years to live if he didn't lose weight), he will probably never be as healthy as he would have been if he had never been obese in the first place. It sucks, but that's the way the body works.

    I was very naturally thin, even too thin until I hit 28 and put on 35 lbs. Honestly, the only thing that changed is I am taking a medication that causes weight gain. However, my friend who was never naturally thin, although was a healthy weight, takes the same medication. She put on 150lbs. The major difference isn't our start weight however. The major difference in weight gain I attribute to the fact that I cook, she doesn't.


    Strangely enough, even though my BMI says I am overweight, I doubt most people would say I am overweight looking, which I attribute to my body type. Most of my fat goes to my behind, whereas if someone put on all their weight in the middle, especially as a woman, they would look bigger and take bigger sizes.
    When I was skinny, any fat I did have was still in my butt, which just made me a thin woman with a round bottom. But if that weight had been on my stomach, I wouldn't have looked quite so thin.

    So there are a lot of factors to being skinny. Genetics, hormones, medication, activity level, and what you learn to eat as a child and your habits as an adult, such as whether you cook homemade meals or eat out constantly. Even where you naturally store fat can affect others perceptions of whether you are naturally thin or not. Combine that with a person who has a small bone frame such as myself and you get a naturally thin person.

    I mean, I'm 30lbs overweight, and I still don't look fat. But my butt and my boobs can only absorb so much of it before it goes to my middle, so I should probably keep using MFP

    Love that story above. That is the behavior of a naturally thin person. It is not luck, it is a lifestyle.

    I was naturally thin all my life, and that candy would have been GONE in a minute when I was younger. Gone and back to the store for more.
    Now I'm older and need to lose a few pounds, which I attribute to medication mostly and I have had to learn to just not buy the candy for my own good.
    But yeah, skinny folks binge on sugar too. My skinny husband just ate the whole bag of candy I bought him in one sitting. Thank god too, or else I'd be on it.

    The "naturally thin" person might be more active (fidgeting, walking around, moving in general). I fidget a lot, and I read somewhere that people who do can burn a significant amount of extra calories throughout their day. Or maybe they just ate the same sandwich but ended up taking in fewer calories in total during the rest of the day.
