KetoNuts have 2g effective carbs per serving and are in essence chocolate covered nuts. I found them reasonably tasty but not great.
I think it was mostly the chocolate that I wasn't fond of. There's a rather thick layer of gushy milk chocolate around each almond, and while it does taste like chocolate the texture is rather wrong.
The almond within is OK, but I would actually rather eat a good can of almonds from Planters or something than deal with the chocolate coating they had on these. Also, at $6 for 4oz they are sort of pricey.
