    Surely you'd need to know how active they are and how they compare with others? "Naturally" thin in my friends translates as more active than the fatter ones quite often.

    This.

    It may seem like some people are "naturally" thin, but the reality is that they are very active.

    Back in the day when I could claim this, my diet consisted of ice ceam, pizza, chicken wings, Little Debbie snacks and 3,000-plus calorie restaurant meals.

    I know people don't think it's possible to eat that much and be thin, but I did. I had no idea how many calories I was even eating back then because I didn't track and I ate smaller amounts of food (by volume) that was VERY calorie dense. And, no, I didn't exercise much at all.

    But when I turned 28, my metabolism decided to take a nosedive and now I eat a fraction of the calories and can't lose for trying. :-(


    28 was my magic age as well! all down hill from there. My diet sounded a lot like yours :) fast food morning noon and night, no exercise

    He struggles to gain and has to eat about 3500 calories while lifting in order to put on weight VERY slowly, and his TDEE is 2500. Must be nice...

    If he isn't gaining on 3,500 then his TDEE isn't 2,500. He should gain about 2 Lb per week if that were the case and he was consistently eating 3500 calories.

    Also, 2500 TDEE isn't crazy high or anything...that's pretty much the average males TDEE with little in the way of deliberate exercise. I'm oldish and not particularly tall or anything and my TDEE is around 2800 calories and I lift 3x weekly and get out on my bike for about an hour 3-4 other days...it's not like I'm doing crazy exercise or anything.

    I've noticed a bit of a trend in this thread...at least a few posts have been women talking about there SOs and talking about how they can eat whatever they want, etc...and it would appear that they don't understand that males in general burn far more calories per day just existing than females do...we can't eat whatever we want...we can just eat more and often a lot more. An average female cannot compare her caloric requirements to her male counterpart and suggest that their male counterpart somehow defies science just because he can eat a lot more than her...that actually is the science part.

    Preach.

    And also, I'm curious if many of those touting TDEE numbers actually have solid data backing them up...as in, a consistent food and exercise log where they have calculated their theoretical TDEE over a sufficiently long enough period of time...or if they're just using a one-week stint where their weight didn't change but they ate X calories so they assumed that *must* be maintenance TDEE. While both are admittedly estimates, one of them is far more likely to be accurate.
  • I'm 5'10" and was quite naturally thin up until after I had baby #3 when I was 30. Then my hormones went wonky.

    I could eat what I wanted before. The difference is, what I wanted before was always savory food. Not to say that savory foods weren't calorie dense, but perhaps the things I was craving weren't so devoid of nutrients. I craved lots of cheese, pastas with good tomato sauce, steak.

    Hormones went wonky and I fell in love with all things cake. Little Debbies Oatmeal Creme Pies? Give me three or four of those at once.

    I never did get too heavy. 171 at my heaviest non-pregnant, but because I've always been willowy it was quite the difference. Before #3 I weighed around 135 to 140. I think that's a good weight for me as opposed to when I started having babies and I was 110. Eight more pounds to go! And yeah, I'm craving savories again.

    People who are naturally thin can eat whatever they want. My roommate has weighed 120 pounds since we graduated high school nearly 11 years ago and eats nothing but junk food. I swear she lives on Totinos Party Pizzas, Oreo cookis, and Mountain Dew and never gains a pound.

    OK. We'll just chalk it up to medical miracles of science. Someone should seriously call a research facility. I'm sure they would be interested in this marvel that defies all laws of thermodynamics.

    I think it's an excuse and scapegoat for those that struggle with their weight.
    Actually, it's just a matter of metabolism. Some people have metabolisms that burn faster than others. There was a study years ago on brown fat and they used identical twins. The more brown fat a person had, the faster that person's metabolism. Eating the same diet, some people (and it was consistent within the twin groups) gained weight, some stayed the same and some lost.

    As I said earlier in the thread, I used to live on a diet of fast food. I ate whatever I wanted and as much as I wanted. Since I started having to watch what I eat, I have discovered I was putting away 3,000-4,000 calories in one restaurant meal alone. A brownie sundae at The Ale House is 2,400 calories alone and I ate those all the time. One slice of the Cheesecake Factory's Godiva Chocolate cheesecake is 700-800 calories and I used to eat that a couple times a week. And I didn't gain weight and I was less active then than I am now.

    Metabolism never varies to the extent which you are dreaming up about and overweight people have higher metabolism. The MFP calorie counter would fully support this statement as your calorie allowance decreases the lighter you are.
    So explain why I could maintain 120 pounds (5'3") eating thousands of calories and now I eat less than half of that and not only can I not lose weight, but I'm gaining.

    I don't care what the MFP calorie counter does. I know what my body does.

    It seems a shame but you actually dont know.... or just made that up.

    You weren't eating as much as you think you were.

    I don't think "Naturally thin" exists. I knew two people in my life who really could eat "whatever they wanted" but they were both diagnosed with hyperthoroidism. It wasn't severe enough for medication but enough to be a hassle, nonetheless. Both had to eat to keep their weight and if they couldn't due to sickness or other reasons they looked quickly malnourished. I remember that both said they wished they didn't have to eat all the time.

    I wasn't skinny but never overweight and I know that I can't eat what I want. If I do, I gain simpe as that. I also thing that a lot of people lie to themselve on how much they really eat. For example despite being almost the same height my cousin always weighed more than I did as a teenager. I was always told that I am so lucky being naturally thin but when I was at my aunts place I saw the reason. She ate about double as much. Her portions were always bigger than mine and she ate everything with tons of ketchup. So it didn't come from nowhere.

    Well, I never had a problem with gaining weight, what I lost now is pure vanity weight. Two and half months ago I hit my highest BMI ever which was 19,8 (54 kg). It took me about 3 years to get from 49kg (which is my ideal weight for me) to 54kg and I currently weight 50kg after 82 days of counting calories. So I can't say I ever had problems with weight.

    To lose weight I pretty much eat the same things, but in smaller amounts and with some adjustments. I limited my soda drinking and I decreased my alcohol intake. Before I would have every day or 750 ml of coca cola or two beers or half a bottle of wine, additionally when I would go out some extra cocktails or hard liquor (usually 3-4 more glasses). My snacks are also way smaller than before I started with MFP, now I take one handful of nuts where before I would eat half a bag. I also introduced more protein to keep me longer full. All in all what keeps me lean is moderation and what gets me bigger is excessive eating, simple as that.

    I am a so-called "naturally thin" person...but I'm fat now. Everyone in my family is skinny (except for me). I eat almost exactly the same way I did when I was skinny, and couldn't gain weight to save my life back then--I even went to doctors to try to gain and many doctors told me I'd NEVER gain, because my metabolism was so high. Again, I eat almost the same way I did when I was stick skinny...maybe even better. The difference for me is once I had children later on life AND developed "sitting disease" A.K.A. a sedentary lifestyle as well as not sleeping as much as I did when I was skinny (staying up late surfing the web and being a couch potato for years on end)--that's when the ugly excess pounds and ounces started piling on big time over the years. Just as I had a hard time gaining weight when I was skinny (and super active and getting a good night's sleep on a regular basis)...I'm having a hard time getting this yucky flab and fat off and keeping it off.

    So...for me, it's not so much the food I'm eating---as my not being as active/my sitting on my tush more than being active, as well as not getting a good night's sleep on a regular basis... that's what helps keeping me fat. :indifferent:

    Every time someone appeals to somatotypes and bone structure, a thin person gets fat.

    FYI: the terms ectomorph, endomorph, and mesomorph are crazy BS made up by a 1940s psychologist who spent all his time looking at pictures of naked people. They don't actually correspond to anything in reality. Endomorphs magically become ectomorphs when they get their diet and exercise in check.

    I understand that somatotypes aren't real. Bone structure is. It does not mean I can eat more with less activity. It simply means I am healthy at a lower weight than someone with a bigger bone structure. It is true that my shoulders are 34 inches, rib cage 26, waist 23, hips 34. It doesn't matter how much someone diets down, they won't make their bone structure smaller. Of course bone structure is a real thing. It's even just common sense. I am small like that and I'm curvy and healthy and not emaciated.

    Bone structure is real, but no one is fat or has a high body fat % or looks fat because of "bone structure." It's an excuse, just like somatotypes.

    3,000+ calories of meat, veggies, fruits, nuts, etc, often times in pizza or fried chicken form.

    Yeah, if a person is fit they will look fit whether they have a small, medium, or large bone structure. Their weight numbers and clothing sizes will just be different. And they still need to eat within their tdee and activity level.

    I will always mention my bone structure being small, so people don't freak out about me weighing 100 pounds.

    It's a fallacy. They SEEM like they eat whatever. But, if you follow them around all day for a week, you'll find that 1) they never ever snack. When they eat, they eat, but they don't eat a lot in a day. They might eat one big meal, and then the other meals are small or they skip them. For instance, maybe no brekky, a huge lunch with people at work, no snacks all day, then they go home and have a small nibble for dinner and that's it. You really don't know unless you are with them all day and night for at least several days.

    While there might be a few cases of this, it's not that common, and I think mostly it's BS. It is CICO and that's all it is. They only SEEM like they eat whatever they want, but they don't eat a lot of calories at the end of the day.

    I have a friend like this. And, it bugged me forever. When we would be out and about, she would eat like a friggin horse, but she was skinny as hell. This went on for years. Finally, I just asked her, because all of us behind her back were talking about it, and I'm just not like that. So, I asked. She just said that she only eats one meal a day and doesn't snack. So, when we were all going out for dinner with friends, she would not eat all day, as that was her meal. That's why she would eat like a horse. But, then that would be it. So, while it seemed like a lot of food, I ate everything she ate in terms of quantity, but I also had breakfast, lunch, and probably some snacks. All she had was the one meal.

    Since at my heaviest, I was only 10 lbs overweight, I *think* I might qualify as 'naturally thin'. I am the opposite of your friend. I snack like hell (you know, you've seen my diary) but I don't like feeling full. I never finish my plate - it looks weird to me to not leave something on my plate. I'm just not really that big of an eater, unless I've been exercising like crazy.

    I always thought my mom was "naturally thin". She had 3 kids and now at 49 years old, she's still a size 2-4 and doesn't work out very often nor has an active job. I didn't realize until a couple years ago when I started watching what I ate, that she eats like a BIRD. We'll go out to dinner and she'll skip the bread/appetizer, eat 3 bites of her meal, and claim to be "stuffed". Ummm...interesting. My appetite is so much bigger than hers, and so is my body :)

    I guess I am what you call "naturally thin", as I was never really significantly overweight.

    But... as a child.. we never drank pop and never had desserts. We never had ice cream in the house, and my mom struggled with her weight, so treats were rarely there either. If they came in the house, she'd eat them.

    I played softball, and spent my summer at the lake swimming and running and playing and not stopping until sundown.

    I rode my bike and played on my climbing structure.
    I played some volleyball, and basket ball.

    My dad is a celiac, so he was allergic to gluten. No flour in our foods for the most part - so our meals were often chicken, veggie, potato. No pasta, no pastries... etc.

    We never had chips in the house either. Nor did we have a computer, or any gaming systems til I was into my double digits (and the time on there was monitored).


    All those treats I rapidly embraced when I struck out on my own... and surprise... all of a sudden I wasn't so naturally thin anymore. I had 25 pounds to lose.

    Physical issues aside... I think as children, as adults... healthy eating vs non healthy eating; active living vs sedentary... The odds of someone being "Naturally thin" and "eating all they want" is usually tied to also being "incredibly active" and/or eating "healthy foods".

    I also think that patterns we set as children also impact how our bodies respond as we age. But that is purely conjecture on my part.

    I have never been overweight as an adult, or even close to. I am counting calories right now because I was not happy for the extra 5 -7 kilos that have slowly crept on me, but I was still not overweight. I used to eat a lot (for one meal) when I was younger and also very thin. But this happened maybe once a day and it was practically my one meal for the day plus I used to move a lot. People being "naturally" thin and eating "all they want" means either they are burning insane amount of calories (I have seen professional athletes eat 2000 calories per meal, but they were training 5-8 hours per day) or their definition of "whatever they want" is not the same as the definition of an overweight person. If I eat 2 slices of pizza this is a meal for me, I really feel full, I doubt this is the case for everyone, I have friends who will eat the entire pizza to feel satisfied. I have a cousin who is skinny (officially underweight) and eats constantly, but it is mostly constant snacking on vegetables and fruit, because this is what she likes. You could not pay her to eat bread, potatoes or meat. I doubt there are people who sit all day in front of their tv, eating pizza and chocolate and stay thin. Would be convenient, but it is not happening.

    I was asked this question today by people at work- not that I particularly view myself as skinny just a normal healthy bmi of 23. I have my main meal at midday so I'm quite often eating pasta or some kind of casserole, with salad and bread followed by a pudding (today was chocolate hazelnut brownie) which is a lot of food compared to everyone else's sandwiches. It emerged that they thought I had something similar in the evening when I actually only eat about 400cals. I also cycle to work, run 3 times a week and do bodyweight training 3 times a week so I'm pretty active. Turns out I eat a lot less than they do!

    I drank 6-9 sodas daily through most of my childhood...and drank chocolate milk a half gallon at a time. Candy bars? Yes, please. Fried food, pastas, bread...all the time. I loved butter and jelly sandwiches. (Hated peanut butter. Still do.) Was still really skinny/scrawny. I stopped those habits for health, not for weight reasons.

    That said, while I wasn't measuring then, I was still consistently eating no more than my TDEE. That's still the "secret". Everyone's TDEE is their own, and eating below, at or above it will dictate their weight trend.

    I was tempted to say "ahh I used to be naturally thin!" and then I had a really solid think about it.

    When was I thin? Before I moved out of my parents house.

    What did my diet look like?
    No desserts, no cookies or cakes lying around. Dinners would be basic and usually vegetarian, made from scratch by my mother. No in-between snacks. Smaller plates. Walking to school and back home, playing outside with my friends in my lunch break. No food to pick at when I was bored. If I was hungry when I got home I was told in no uncertain terms to wait for dinner. If there was too much food I just wouldn't eat it.

    So I'm going to say that this extra 30lbs is the result of eating bigger portions of more calorie laden meals, snacking and picking at food when I'm bored or just feel like having something tasty. It's clearing my plate every time. It's the condiments and the sauces and the tasting from the pan, it's red wine and good gin. It's 30lbs of public transport and desserts and eating out more in the average month than I used to in the average year.

    I think it's the little things. They add up.

    Before I got into lifting weights and tracking my calories to gain weight I used to just "eat what I wanted" without ever going over 100lbs. We all know by now that losing and gaining is about calories in vs calories out. Like others on here have said, those people like me just either weren't eating over their TDEE or they were burning a lot more calories than you think. I happen to not like chocolate or cakes or chips or anything like that. I've always preferred to eat fruit. That was my dessert or snack. But I did eat fast food and go out to eat but if I went to say mcdonalds and ate a burger fries and shake I would literally be full the rest of the day. If I did eat later it would be a small snack like fruit. So I was just not going over on calories. This is why I never gained weight. When I started tracking calories I was eating much more often but better foods and found I was still not gaining. It took me some time to realize what my actual TDEE was in order to gain but it felt like I was eating so much more food. Also people who say they barely eat anything all day are just eating over their calories and not realizing it. I have a coworker who told me he hardly eats all day but he's not losing weight. I asked him what he ate that day and he said a big cup full of tostito chips. I looked at the bag and 6 chips were 150 calories. He couldn't believe it. Then be forgot to include the giant coffee he drank with tons of cream and sugar. He also admitted to eating a ton of Indian food at dinner. So for someone like him he didn't eat much all day but what he did eat was high in empty calories and then his dinner probably just put him over his TDEE.

    I'm offended by the "there may not be many of you on here" comment that I can't clarify my thoughts enough to say anything more

    But they don't exist. Truth is they may appear to eat more than you, they either don't or they are far more active. You can achieve the same, medical conditions aside, if you practice the same habits.

    not true. I have a lazy skinny sister who eats all of the time. she eats more calories than me most days and im more active than her and im the one on a weight loss site. her metabolism is crazy high and sorry to say they do exist

    I disagree. Naturally thin people eat less and or move more

    My father is 'naturally thin'. His ribs have always been visible and as a young man it bothered and he spent years trying to gain weight. And he eats a lot! He snacks and has full meals. And drinks lots of beer. While the food tends to be healthy (read unprocessed) it is often high cal for the main but he also loves veggies and eats a huge amount of salad a day and has both chips with homemade salsa and dark chocolate everyday.

    I always thought he was naturally thin and part of my problem was in learning portions from him and my mom but the difference is his activity level. He doesn't sit down. Or stop. Ever. He hikes, climbs, bikes, gardens, plays ping pong, cleans, whatever, he just moves aside from watching the occasional movie or reading for 30 minutes in bed in the evening. He once said to me that he'd noticed that I never move, that when he thinks of me its on the couch as thats where I am when we talk, I read, we watch shows, I eat, ect.

    In short he can eat whatever as he moves lots and I need to eat less and move more until I find my balance.

    Besides the points made by others explaining why some are "naturally thin," studies have been done that show that yes, on some days, they consume huge amounts of calories. The next few days, however, these "naturally thin" people have been shown to consume less than normal calories and/or move around more, thus negating the day of overeating. One day of surplus followed by days of negative caloric intake to balance everything out. In general, they also fidget more, increasing their NEAT by as much as 400 calories a day.

    I used to do metabolic testing in a hospital, and we'd get those people who claimed they ate a ton of food and couldn't lose weight. Did they have super fast metabolisms? Nope. They thought they were eating a lot because they ate until they were full. However, it took very little food to make them feel full. Sometimes it was hard to get these people to be still for the duration of the test because they were such fidgeters.

    This! The few naturally thin friends I have seem to get full way faster than I do. I remember seeing one of them look at a Chipotle burrito bowl and being like oh my god this is so much food! Whereas I can stomach a burrito bowl and a whole bag of chips, easy and not be stuffed. I figure after reading all these responses people who are able to maintain a healthy body weight without counting calories, have a better handle or better hormone regulation genetically for the hormones that signal fullness.

    I am one of three brothers. The oldest and I were always chubby. The middle brother was always "unnaturally thin" while eating anything and everything. Then in his late 20's he discovered he had graves disease and a host of other problems with his thyroid. Now we know why he could do what he did. After getting his body in check now he is like a normal person.

    Don't just assume people who are thin yet eat anything they want are truly healthy inside.

    You wouldn't believe how many times doctors have asked to check my thyroid and they find nothing.

    My children are all thin. Same thing. (ETA, yesterday they spent the afternoon sucking down whipped cream from a can. I bought it for a party. Little spazzes.)

    There is one freak of nature in this documentary who ate and ate and ate and didn't get fat. There is one woman who simply could not eat the required amounts of food no matter how hard she tried. That is two of ten who didn't get fat in a month of deliberate gorging.

    I would like an answer on this. Am currently watching "why are thin people not fat" on youtube. Very interesting stuff and seems to partly go against what people are saying. This one asian dude ate a ridiculous amount of food and gained muscle instead of fat. This other person ate twice the calories they should've and didn't gain any weight. I know people like to come on strong with their usual copy and pasted "well hur hur, unless they can defy laws of thermodynamics, they aren't eating as much as they think they are!" but i predict most on here aren't scientists that study this issue extensively. Just people that count calorie with an app on their phone and pretend they know everything. I think largely the "a calorie is a calorie" is sound logic for 99% of people out there, but that there are freaks of nature who have bodies that do something else.
