I didn't go full keto, or cut carbs entirely, but I dropped 30 pounds and went from a recent diabetic A1c of over 8 down through pre-diabetic syndrome levels to "normal" 5.7 in about 3 months. Blood sugar welll over 300 regularly, down to a 80-120 range. Love that keto options have become common enough to fill in some of the carb desires. But yeah, travel is rough. At least most hotel breakfast have eggs of some sort. Become a big fan of traveling with a bag of various nuts.
