Look in the bread aisle of a grocery store, and you'll find dozens of different wheat breads: multi-grain, whole wheat, rye, pumpernickel, white, sourdough, pita... just to name a few. Sadly, none of these options fit the keto diet.
Exact numbers vary between each variety of bread, but a single slice generally contains 10 to 20 g of net carbs. That's high enough that a single slice could push you over your carb limit for the day.
The problem ingredient in bread is wheat flour. Your body converts wheat into glucose (sugar), which spikes insulin levels and causes you to store the sugar as fat.
