Using oat flour while following keto
For a 20 g keto day, 1 cup (104 g) of oat flour supplies 61.5 g net carbs, which comes to 308%.
A single serving of oat flour exceeds a full 20 g keto allowance by itself, so it is difficult to include.
In that same serving there is 15.2 g of protein, 9.5 g of fat and 420 kcal of energy.
Net carbs equal the 68.3 g of total carbs in oat flour minus its 6.8 g of fiber.
Bread brings fewer carbs than oat flour, at 13.5 g net carbs in each 1 slice (29 g), so try it.
