Here's the link.

I heard about this on the radio this morning and had to look it up as it sounded ridiculous. I haven't looked up the actual study in the journal yet.I don't know how many mice they used, etc.

OK, I know I'm not a Biochemist, but this just seems like BS to me. What if the sense of smell makes us eat more, even if we're not hungry. There are many other animals that have a strong sense of smell than mice and humans (dogs, for instance) and they're not all fat.

And the losing-your-sense-of-smell potential side effect of a heart attack, kinda a draw back in my opinion. ::eye roll::

Does anyone see the validity in this? Cause I'm not.

    What's a food cat?

    :lol:

    Sorry I didn't read the article, but I agree with your BS claim at first thought.

    Sorry. I didn't answer your question originally because I was entertaining myself.

    Obviously, smelling food can't make me fat. But, I have smelled something good that I didn't plan on eating and it smelled so good I did eat it. If I didn't allot for those extra calories, or never exercised my self-control and ate everything I ever smelled that smelled good, I could gain weight.

    I read the study and it made sense. They "killed" the smelling nerves of rats. Healed after 3 weeks. Those rats lost weight during that time. Simple study.
    My first thought, why not kill the sense of taste while they are at it?

    Yes, the study said the rats ate the same amount of food. Crazy !!!!
    These smell-deficient mice started turning their beige fat cells, used to store fat around the body, into brown fat cells, which burn up fatty acids. What's more, their white fat cells – which store fat around the internal organs and can cause health problems if too many build up – got smaller.

    Next: Walk in clinics at malls where they can "burn" your nerves of smell in your nose. They can call it "zappy's".
    I see that skunk spray ad coming back.

    They're connecting weight gain to sense of smell because mice without smell ate the same amount as mice with smell, but only the mice with smell gained a lot of weight. So, for their results, sense of smell means weight gain in mice.

    I still think it has to be something else.

    It's got to be.

    The findings suggest that the odor of what we eat may play an important role in how the body deals with calories. If you can’t smell your food, you may burn it rather than store it.

    But why would the body burn it? Where are all of our super smart scientific MFPers?

    My husband has loss of smell and it definitely made him lose weight as a result, he says takes enjoyment out of eating. He gets course of medication every few months to regain smell but eventually the benefits wear off.

    I think I would be depressed if I lost my sense of smell, even if it meant weight loss. But an interesting study. If the same consequences are seen in humans, I wonder if the risks would be greater or less than weightloss surgery for the morbidly obese.

    (checks calendar - not april 1st?)

    I work with elderly people and many of them have lost their sense of smell for one reason or another and they do lose weight but it's because it affects their appetite and food no longer brings them enjoyment. So many of them complain that food just doesn't taste the same and they refuse to eat or consume so little that they just waste away and become very underweight, they lose a lot of muscle too and being underweight brings about just as many health problems as being overweight does. So I'm wondering if this did work, the people who they temporarily take the sense of smell away from would just go back to eating as much as they did before once the sense of smell returned. Possibly they'd eat more because they'd missed out on the enjoyment of eating for so long and gain weight again. Then they'd need to have their sense of smell taken away again to lose the weight once more and it would become a viscous cycle, since they never really learned to control food portions. Yo-yoing their weight up and down over and over, that can't be good either, so I think this would be an experiment that might not translate well from mice to humans.

    Food aroma has a physiological response, for sure. It may slightly raise insulin levels, but that likely quickly recovers. It definitely increases appetite, but that can recover as well, depending on if you indulge it.

    I've gone past many enticing food aromas while exercising, and it has an immediate effect, eg, "cant wait for dinner."

    Luckily, my Food Cat often provides.

    I was just in the grocery store. The smell of freshly baked cookies sure made me want to eat them. My guess - without reading the study - is that if something attracts us by smelling yummy people (not focused on eating right and losing weight) are more likely to eat them.
