    Default Does IF diet improve olfactory sensitivity?

    I recently went on an intermittent fasting diet (past 2 weeks) to improve my gut but also to improve my overall health and one surprising side effect is that my sense of smell seems to have improved, I can smell the later stages of a perfume for longer and I can more easily isolate and identify notes in the perfume. So I am wondering if the fasting is causing this olfactory sensitivity or if it's my overall health improving or my daily workouts?

    No. I did IF for a while. I ended up gaining weight (I binged terribly when I was allowed to eat). It made no difference in what I could smell or not.

    Ignorant here-what is an intermittent fasting diet?

    In any case, interesting. Olfaction is an important part of taste, so who knows, perhaps pauses from tasting help sharpen the sense of smell.

    I've been doing intermittent fasting for about a year in order to improve overall health and energy levels, and it has really worked for me - however, I am not aware of any change in olfactory sensitivity. For those interested in learning about IF, this is a good introduction: https://www.healthline.com/nutrition...sting#section1

    Just means skipping meals at certain times. Some might skip them for a day a week. Personally I simply stopped eating after 5pm,which may or may not count as intermittent fasting, when I wanted to lose some extra padding. Don't think it influenced how I smelled perfume but it's possibly, considering how good even boring food tastes after skipping meals, perhaps perfumes can become more attractive as well .

    just to throw this out there but developing concentration (specifically via meditation/energetic practices) can dramatically improve your sense of smell more than any other factor. if the fasting has made your core energy more stable than a similar effect may have been gleaned. it's all about being coherent so the space inside our experience starts to open up

    it isn't even about our physical nose/brain per se as our sensory perceptions are a much more direct thing where the ability be aware or tuned in (concentration) is a bigger factor in being able to consciously pick things up.

    Perhaps more this.

    I couldn’t say with the relatively limited time spent fasting with IF, but when I was unable to eat for extended periods due to illness my sense of smell became very sensitive.
    1. No, never blind buy (I do, but do as I say, not as I do. I'm taking no responsibility for your fragrance gambling).
    2. Get them both. You're a Basenoter and you know you're going to end up purchasing them both eventually.
    3. Yes, it has been reformulated.
    4. Looking for a signature scent? You've come to the wrong place.

    Maaaybe a tiny bit because being hungry means you’ll tend to notice all smells a bit more while your lizard brain is hunting for food, but nothing appreciable.

    The things that might affect your olfaction outside of a general health uptick from IF are some of the ancillary benefits that sometimes come with it...namely a reduction in inflammation, ketosis and your connection to the moment (as others have said, mindfulness practice and cognition).

    If your body has become better at dealing with inflammation and your mucus membranes were clogged, sure. You’d probably also notice your throat feeling miles better.

    If your brain is fueled by ketone bodies, it can potentially operate at much greater efficiency, hence that connection to the moment. If you’re meditating in addition to your fasting (common practice), then stay gold, ponyboy.

    Increased sense of smell could help with sniffing out food.

    Thanks guys, I feel like something in my primitive brain is activated probably for seeking out food through scent, and I only really notice it during the periods when I haven't eaten for at least 10 hours so it could be my sense of smell kicking into overdrive to snuff out grub. We are all different, we all have different problems and conditions so I'm kind of just trying to paint a wide brush over this topic and see if it's effective even to a small portion of people, because I could be an outlier.

    Yep, I became very sensitive to food smells in particular

    I could smell when someone cut a vegetable at the other end of the house.
    Citrus fell into that category too, although I did find myself generally a bit more perceptive/sensitive to things like florals from the garden. I never wore perfume at that time (hated perfume and people who wore it!), and neither did anyone around me, so I can't say what effect it would've had on smelling perfume.

    Probably has more to do with skin hydration, sebum content and ph than with improving olfactory sense.

    I only eat after 15. Don't like to eat in the first part of the day.

    It's winter here. I have been using a humidifier at home. It raise the humidity from 31 to 50. When it's dry (31) I have all sorts of problems, including olfactory issues.
