This is not scientifically tested, but here is my discovery. This summer, even though I have been outside a good bit of time I have had 0(zero) mosquito bites. Last night after my sugar binge I ended up with a bunch of bites. Did my low carb diet have anything to due with my lack of bites? I think so. I have no way to prove it, but this is the first summer I have ever lived without mosquito bites.
