Low-Carb Fruits and Fruit Snacks for a Keto Diet

Understanding Carbs in Fruit

All fruits contain carbs since sugar is the main energy source for plants. However, the net carb content varies greatly among different types of fruit.

Net Carbs

To calculate net carbs, you subtract the grams of fiber from the total grams of carbohydrates. The fiber content is indigestible plant material that does not impact blood sugar.

For low carb diets, you want to focus on net carbs to determine a fruit’s true effect on ketosis and blood sugar control.

Glycemic Index

The glycemic index (GI) measures how quickly a food spikes your blood sugar. Lower GI foods cause a gradual rise while higher GI foods lead to rapid spikes.

Choosing fruits with a lower glycemic index can prolong ketosis and stable energy levels when eating a low carb diet.
