Teaser makes an excellent point about accuracy comparisons of strips, breath meters, and blood meters. This is why I use the blood meter. Once you establish a baseline by understanding how you react to keto foods, you don't need to use it so often. The meter I use now is the Keto Mojo. Strips are less expensive.

Also, my infrequent consumption of the carb foods I used to crave like pizza or fried clams (yes, I'm a transplanted coastal New Englander) are never as good as my memories. That's why it's so easy to do my infrequent one and dones when I go off the grid. Usually, it's "what was I thinking?!?" Then I'm right back to today's normal.
