Is Corn keto?
Not keto-friendly 14.7 g net carbs per one medium ear (90 g) — 74% of a 20 g keto day.
Short answer: Not in normal portions. One medium ear (90 g) of corn: 14.7 g net carbs — 74% of a strict 20 g keto day — with 1.3 g fat and 3 g protein.
Sweet corn is botanically a grain and behaves like one in a keto budget.
How corn fits a keto carb budget
On a 20 g day, one serving uses 74% of your budget, leaving 5.3 g for everything else. Measure portions rather than eyeballing them.
Worked example. 90 g of corn = 17.1 g total carbs − 2.4 g fibre = 14.7 g net carbs, 1.3 g fat, 3 g protein and 77 kcal.
If you still want some, plan it: a strict day is 20 g, and how net carbs are counted explains why the fibre here does not rescue it.
