Are Plums Keto?

Fresh plums fall on the list of approved fruits that Ketogenic dieters can eat.  A medium-sized plum containing 7 grams of carbs makes a healthy addition to a low carb meal plan.  The fruit is low in fat, so you might want to consider combining a plum with few nuts or a slice of fresh cheese to get some healthy fat. 

Dried plums, also known as prunes, however, should be avoided on Keto. Just one serving of this dried fruit can cause you to exceed your daily carb count.

How Many Carbs are in Plums?

Fresh: A small 66-gram plum (2 1/8” in diameter) contains 7 grams of net carbs.  The total carbs in a small plum is 8 grams, but once you account for the 1 gram of fiber it contains, this number decreases to 7 grams of net digestible carbs.

Dried: A 100-gram serving of dried plums (prunes) contains a whopping 64 grams of carbs.  The carbohydrate amount in dried fruit tends to be more concentrated compared to fresh fruits.

How Many Calories are in Plums?

Fresh: A small 66-gram plum (2 1/8” in diameter) contains only 30 calories. If you’re following a calorie-reduction plan, fresh plums make a much better food choice over the dried variety, containing only a small fraction of the calories.

Dried: A 100-gram serving of dried plums (prunes) contains 240 calories. Dried prunes are much higher in calories than fresh plums due to their shrinkage after dehydration, making them a more concentrated form of energy.
