Is Maltitol Keto?
Maltitol is not keto-friendly because it is a high-glycemic sweetener that may kick you out of ketosis even with small amounts.
Maltitol has a high glycemic index of 35 which may cause your blood sugar level to spike.
It is also linked to an increased risk of chronic diseases such as obesity, cardiovascular disease, and diabetes.
High in Net Carbs
Maltitol should be avoided on keto because it is high in net carbs (5.3g of net carbs per 10g serving).
It is important to limit your net carb consumption to 20g - 30g per day to stay in ketosis. You can calculate your ideal daily net carb allowance by using this keto macros calculator.
