Frequently Asked Questions (FAQs)

1. Can I have sugar-free syrup in my coffee on keto?

Jordan's brand offers a variety of sugar-free coffee syrups that you can use if you're on a keto diet. There are regular skinny syrups (click the link to check them out on Amazon), which are sweetened with sucralose.

2. Can you have Torani sugar-free syrup on keto?

Torani Sugar Free French Vanilla Syrup is low in net carbs but it should still be avoided on keto because it contains unhealthy ingredients like acesulfame K, sodium benzoate, and sucralose.

3. What can I put in my coffee on keto?

Keto coffee tastes good, but not quite like coffee with milk and sugar. Many people also add keto creamer, monk fruit extract or stevia, keto-friendly extras like cocoa powder, cinnamon or vanilla extract for added flavor, and protein or collagen powder for additional benefits.

4. Can you use flavored coffee on keto?

To keep it keto-friendly, you should make sure that you're using sugar-free syrups because the sugary varieties have way too many carbohydrates to be keto-compliant. Another option is to add spices to your black coffee like cinnamon, cardamom, or pumpkin; it's up to you.
