Reality Check: Skinny People Must Have Fast Metabolisms

Ehm hi... I'm Andrea and I used to believe about fast / slow metabolisms.

That was my main excuse why my sister was skinnier (ok, she still is) than me. We have different bodie types but she used to eat a LOT and being skinnier than me. So I'd cry around saying how unfair it was and why I'd not have my mom's genes just like my sister..

Until I came here and I learned all of these things and I started to observed my sister and my mother and found out that they were really, really active! The whole day! At least my mom never seems to stop! .

So there it is.. I will accept that at some point I was THAT person making excuses for herself. But now I know that the only excuse that I had was my own. :flowerforyou:



She is very, very annoying, but I like this quote...

High NEAT definitely contributes to why I can eat so much. I notice when I'm out with friends that I tend to be the first to move to chase escaping toddlers or whatever.

I want some of that water stuff they had the lady take. Oooh ooh, then afterwards you can pee on a stick, and it'll reveal a number with how many calories you consumed. I'll market it and make $BILLIONS$!!! I shall call it "Peelories" :laugh:

Interesting videos, thanks.

My guess is that the second video, she was recording what she thought serving sizes were, not what they actually were. That's easy to do, especially for someone who is naive of how food labels really work. She seemed genuinely shocked (and hurt) when they told her she "hadn't recorded 43% of her intake", which makes me believe she actually wrote down everything she ate and just didn't know what had which size of serving.

I was wondering how PCOS played into metabolism, as I know people with PCOS struggle to lose weight. However, doing a quick look at pubmed left me wondering if it's really that important of a player. A few articles I skimmed for metabolic and PCOS looked at obese and healthy body weighted individuals with PCOS, leaving me to reconsider the originally believed strong connection between the two.

YES!!! This is an awesome vid! I hav to tell this to people around me (including doctors). Its ridiculous.

One thing though that is surprising is the second video. Anyone who watched the complete documentary able to tell if she was underestimating her eaten calories or just logging food she ate at all?

I saw it years ago, and I remember that fruit salad being huge compared to what she reported.

:-)

I'm tagging this so, "bump."

Thanks for posting. The biggest truth that people will find anything to ignore: calories in vs calories out.

The woman in the second video seems really intelligent and on the ball and genuinely surprised by the reporting. Most people are simply not aware of what is going into their bodies and over time their markers for correct portion size/frequency/content are skewed.

I think whether you agree or not is irrelevant, what matters is whether or not you're willing to work with what you've got. Even if you do have a slow metabolism, are you just going to sit back and accept it or are you going to do the extra work?

obesity is a result of eating more than your body needs , fact... They wouldn't be OBESE if they didn't over indulge . We all know how easy it is to hit 3000calories in one day off junk food ( a large big mac meal with a coke / then a milk shake then some nuggets = 3000 calories lol) . So come on , blaming their metabolism is the last thing they should blame .

I must not have phrased that the way I meant for it to be, because I don't really see why you are taking exception to what I said. I was just trying to say that even IF you think your metabolism is slow and that your "skinny friends with fast metabolisms" have an unfair advantage, well, tough t*ts. Life isn't fair, the playing field is never level and if you have to work extra hard then you have to work extra hard. Their metabolism is probably the last thing they should blame, my point was more that no one is going to work off the extra weight for them.

Metabolism does slow down with age, about 5-10% less per decade after the 25th birthday. However, this slowdown is easily counteracted by exercise.

Food consumption isn't fixed either...

Will watch these later! Thanks for posting!

Bump

Bump

Tagging for later

I know it's not always a valid excuse but it is true for some.

Very true.

Same with being born with a tail.

OK... I just spat tea everywhere........

Doubly Labelled Water throws it all out in the open. LOL :laugh:

How can you just "forget" about 43% of what you've eaten??

I don't think they necessarily forget, I just think people suck at estimating portions. Many many times you'll see threads here where someone says they're eating low calories and not losing weight, and then it turns out they aren't weighing/measuring, or they don't log weekends. Although, I do think it's possible to forget about little things like a handful of M&Ms from the candy jar, licking the bowl while baking, or snagging a few crackers on the way through the break room, etc. People are really good at self-deception. The results are similar to this study, which found that even dieticians under-report their intake.

http://www.ncbi.nlm.nih.gov/pubmed/12396160

In this study they compared caloric intake from 10 female registered dietitians and 10 women of comparable weight who were not dietitians and the study compared the energy intake obtained from 7-day food records with energy expenditure measured over the corresponding 7-day period using doubly labeled water.

Participants were told that the goal was to record food intake as accurately as possible, because it would be compared with the simultaneous measurement of energy expenditure determined by doubly labeled water.

Dietitians underreported their food intake by an average of 223 calories per day, while the non-dietitians underreported their intake by an average of 429 calories per day.
