Is fructose keto?
Not keto-friendlyCounts in full
No. Fruit sugar. It has a low glycemic index, but it is still sugar and counts toward your carbs.
What it is
Fructose is the main sugar in fruit and honey. Its glycemic index is low because the liver processes most of it, which is why it is sometimes marketed to people watching blood sugar.
Low glycemic is not the same as low-carb. Fructose is fully absorbed, it counts toward your daily carbs, and it does not belong in a keto product.
How to count it
Count every gram toward your net carbs.
Sugar under another name. Count every gram.
Where you will find it
- “Diabetic” sweets and baked goods
- Sports and energy drinks
