Kefir is a fermented milk drink with live cultures and a tart taste. Whole milk plain kefir works on keto in small amounts.

Keto notes

  • About 4.5g net carbs per 100g from natural lactose, so watch your portion
  • Stick to a small glass rather than a full cup
  • Always pick plain whole kefir, never flavored or low-fat versions with added sugar
  • Good for gut bacteria and an easy source of protein and fat

Count the carbs into your daily total and it stays manageable.
