Keto Snack Bars
We ran 250 snack bars through our keto rules: 3 pass, 1 need a label check, and 246 don't make it.
Most cereal bars are sugar syrup pressed into shape; 40 grams of carbs per 100 is typical and fails on the spot. Nut-based and specifically low-carb protein bars are the survivors. Check the polyol on anything labelled keto, since maltitol still moves blood sugar.
