Is Grapefruit Keto?
A 1/2 fruit (123g) serving of grapefruit has 11.2g of net carbs (13.2g total carbs minus 2g fiber). That is workable on keto in a controlled portion but adds up quickly if you overdo it.
To stay inside a 5g net-carb budget, keep the portion to about 55g of grapefruit. Track it against your daily total and pair it with higher-fat, lower-carb foods so a single serving does not use up your whole carb allowance.
