Yes in moderation.
100 g of raw red cherries has 12 g of total carbohydrates, and slightly less than 10.5 g of net carbs, which puts cherries at the very edge between allowed and allowed in moderation when it comes to the keto lifestyle.
Cherries are also rich in Vitamins A and C so they shouldn’t be completely disregarded just because they’re little higher in carbs. You can eat a handful of cherries few times a week in season, and still meet all your macros.
