I have been eating mostly ketogenic for almost 1 year now. I love it. I look better and I feel better and I eat wonderful foods.
I live in the Netherlands, in the countryside. Lots of water and lots of mosquitoes. But. I have not been bitten once this year. Is that a coincidence or does it have to do with eating keto?
I believe it is not a coincidence. I have been keto for almost 8 yrs. and noticed that mosquitoes no longer seem to like me. Or if they are biting, I don’t react. Either way ~ it is a non scale victory!
I’ve noticed the same thing. I think it’s a combination of not being as yummy to them and not reacting. I did get a few black fly bites last weekend, but they never itched, when they can usually drive me insane!
I was listening to a podcast (not on 2 keto dudes) and a listener asked if being in Ketosis reduces a person from being bitten from mosquitoes…
The host did not have an answer and he had not heard of such a phenomenon.
Mosquitoes love me too. I swell up & the itch lasts for at least 3 days.
The past 15 days I have been sleeping outside in a mosquito/Noseeum tent. I have noticed I haven’t been bitten as often. Perhaps it’s because I run indoors to avoid them. J/J Lol. 
Hard to keep away from them since I live in Florida right beside a beautiful bayou filled with these bugs waiting for a quick meal.
I’ve heard the saying “mosquitoes love you because you taste sweet.”
Perhaps there’s a correlation since ketonians reduce the amount of sugars in the body and maybe we don’t give off a certain type of “tasty fragrance” and so mosquitoes attack others. I’m not sure if there’s a pheromone that we release while we are in ketosis or while we are fat adapting.
I am interesting to see if someone will write a journal and test while not in a ketosis state and sitting outside at twilight and allow the little vampires suck their blood and then run another test while in the state of ketosis.
Once I am past my fat adaptation phase and can properly gauge when I am in and not in ketosis then I will be willing to do this experiment. 
It would be so awesome not to have to use deet spray.
Interestingly enough, mosquitoes are drawn to carbon dioxide, so if you expel less carbon dioxide, they may not become attracted to you. I personally find that on keto, I don’t breath as heavily in general. That may have something to do with it.
A mosquito might smell our body odor left on some linen, or smell our excrement, and we could be miles away. When traveling in areas where mosquito-borne diseases are a concern, take measures to limit your exposure and consider using an insect repellent. Last week I had noticed something odd, I found mosquito was flying around my room and not once did it try and bite me. I had called Pest Control Ridgefield CT services to control mosquitoes were the experts provided the best-suited method for the situation.
This an older thread but I noticed the same thing this past summer!
We have a screen door and the flies, mosquitos etc. and Gwad knows what other kind of critters, thousands would just hang around and congregate around the screen door all day long until it got dark and as soon as I started keto they just suddenly disappeared, after years and years of this reoccurring every year thereafter and it just came to me today that they were after me (I cannot believe that) even though my room is way in back of the house where I am most of the time!
I don’t know why that hit me just now, while I was standing outside and thinking about how the mosquitos use to love to bite me up real good, I think they were after the high glucose in my blood and breath (I use to eat a lot of sugar and high carbs)? And now that I am expelling ketones they do not like that! (it was really nice not having to battle flies {flies too} and mosquitos with fly swatter in the middle of this year)
Now what has me curious is these factors:
1. carbon dioxide (heat)?
2. body odor!
3. blood type?
4. lactic acid?
5. other secretions?
6. high glucose (my theory)?
…if that (Ketosis) some how effects these factors?

The mosquitoes eat me like crazy after 7 weeks of keto so that must mean I’m not burning ketones or I’m not fat adapted, what do you think ? I’m at less than 20 gram carbs and drink half my body weight in water eat 2 avocados per day eat lots of lo sugar veggies like broccoli and cauliflower using extra virgin olive oil And eat 6 eggs through out the day, I’m male 55 and went from 250 pounds down to 218 now and just trying to do everything right like taking magnesium malate 1 Cap at each meal, 3 per day, and if I sweat real bad playing golf what do I lose besides sodium? Do I lose potassium? Ty
Uh, not my experience! Unfortunately, I just got back from vacation and our first hike on Chincoteague Island Refuge, in spite of 3 layers of repellent, and I was lunch! That was my last walk in the wilderness! Color me a beach babe!
Since I’ve been carnivore (almost 3 months) mosquitoes aren’t biting me.
I walk my dogs in the late evening, south Louisiana, and in the past I would be slapping at them swarming at my face, ankles, neck. Not so this season. I was beginning to think they weren’t around, but they are when there are others present.
The times I’ve been bitten this season, I was outside standing/sitting next to a sugar burner.
Pre-keto I would get 10-12 bites every time I sat outside. They would swell and itch for days. Been keto for 3 years maybe had 10 bites total but they go away fast.
This week we vacationed in St. Maarten- my husband and I both keto for 3 years. We sat at lunch with a couple and they complained the whole time about bites -20-30 all over them. My husband and I looked at each other and just smiled. After lunch we laughed, absolutely NO bites for either of us. It is NOT coincidence!!!
Wow, I had no idea that keto works, I hate mosquitoes. That diet is good for everything honestly it has worked great for me, but for some reason I stopped doing it. Mosquitoes were killing me this summer and I had to find some repellent to stop them. There is a little lake near my house and that is why there are so many mosquitoes there. I found organic natural mosquito repellent that when you drop it in water kills all the larvae there. After doing that there were less and less of them every day. Combination of this with keto can work really good I think.
As I just mentioned in another thread, I have always found that lower sugar consumption makes me less attractive to mosquitoes, and higher garlic consumption also helps (but you have to have eaten the garlic long enough beforehand for the smell to start coming out your pores). I also find that my allergic reactions (such as to mosquito bites) are much, much weaker on a ketogenic diet.
Mosquitoes love, and I mean LOVE, me. This has not changed, after 7 years. I have to use DEET and make sure I cover every possible location (back of knees, ankles, etc.), and wear a lot clothes or put blankets on and put a fan on me.
This makes me wonder if you are eating any artificial sweeteners still; so that your scent/taste would still be sweet and appealing to them?
I was just curious if this could be a factor in them still being drawn to you.
If you don’t consume any, then I guess there is no correlation.
I eat artificial sweeteners…sometimes. I’d characterize it as rarely.
But I don’t think it matters. I can walk outside when mosquitoes are out and even moving around, I’ll get bitten in minutes. They just love me.
Pre-keto, I went to St. Croix. I got bit by far more than anyone else, and I mean by far – 10, 20 times what others got.
Whatever I produce that mosquitoes like, I still produce it.
I have tried Vitamin B1, but I never could take it regularly enough to test it.
Back in the day, Avon Skin-so-Soft used to be our mosquito repellent of choice. Avon resisted for years, but finally gave in and started marketing the product as such (it was supposed to be a moisturising bath product, but “greasing-up bath product” would have been a better descriptor; trying to get the greasy ring out of the tub was a real challenge).
keto hasn’t changed that fact.
