Is Milk keto?
Not keto-friendly 11.7 g net carbs per one cup (244 g) — 59% of a 20 g keto day.
Short answer: Not in normal portions. One cup (244 g) of milk: 11.7 g net carbs — 59% of a strict 20 g keto day — with 8.1 g fat and 7.8 g protein.
Milk is where dairy stops being keto-friendly: a cup holds about 12 g of lactose. Cream, unsweetened almond milk or coconut milk are the usual replacements.
How milk fits a keto carb budget
On a 20 g day, one serving uses 59% of your budget, leaving 8.3 g for everything else. Measure portions rather than eyeballing them.
Worked example. 244 g of milk = 11.7 g total carbs − 0 g fibre = 11.7 g net carbs, 8.1 g fat, 7.8 g protein and 149 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.
