Using Sweeteners on the Ketogenic Diet

Refined sugar should not be used as part of a ketogenic diet. Some sweeteners can be used as an alternative option to sugar as part of a ketogenic diet, as they do not affect blood glucose or ketone levels. Other sweeteners should not be routinely used as part of a ketogenic diet.

Please see a list of sweeteners below:

Go ahead!

Acesulfame potassium (acesulfame K, or ace K)
Allulose Aspartame
Cyclamate (sodium cyclamate)
D−tagatose Erythritol
Monk fruit sweetener (luo han guo)
Polydextrose Saccharin Stevia
Steviol glycosides Sucralose

These sweeteners CAN be used as part of a ketogenic diet

Proceed with caution!

Glycerol (glycerin or glycerine)

Discuss with your dietitian whether these sweeteners are suitable for you or your child


Corn sugar (corn sweetener, corn syrup solids, high fructose corn syrup)
Hydrogenated glycose syrup

Hydrogenated starch hydrolysates (HSH) Invert syrup
Maltitol syrup
(maltobiose or malt sugar)
Polyglycitol syrup

These sweeteners are best avoided as part of a ketogenic diet

We recommend that you avoid overuse of any sweetener, as they can sometimes cause stomach upset and may encourage a taste for sweet food and drink. Start with no more than 1 teaspoon (5g) a day. Please be cautious when introducing products that contain sweeteners and monitor ketones.

Remember:  ‘sugar−free’  does not necessarily mean  ‘carbohydrate−free’.  Always read the label carefully or check with your dietitian!
