Navigating Sweeteners on a Low-Carb Diet
Choosing beverages on a low-carb or ketogenic diet involves understanding how different sweeteners affect your body. While the goal is to minimize carbohydrate intake, not all sugar-free options are created equal in their impact on blood sugar, gut health, and cravings.
Keto-Friendly Sweeteners
Certain non-nutritive sweeteners are generally accepted on a low-carb diet due to their minimal impact on blood sugar and insulin levels. These include Stevia, Monk Fruit, Erythritol, and Allulose.
Sweeteners to Use with Caution
Some sweeteners may have a moderate impact or require careful consumption, such as Xylitol and Sucralose (Splenda). Aspartame is another zero-carb artificial sweetener with debated long-term effects.
Sweeteners to Avoid on Low Carb
Sweeteners like Maltitol and Isomalto-oligosaccharide (IMO) can raise blood sugar and should be avoided. High-fructose sweeteners such as Agave Nectar are also detrimental.
Beyond Carbohydrates: Other Considerations
The impact of sugar-free drinks extends beyond carb counts.
Gut Health
Some artificial sweeteners may negatively alter gut bacteria composition.
Cravings
The sweet taste can perpetuate sugar cravings.
Recommended Low-Carb Beverages
Unsweetened options are ideal: Water, Sparkling Water, Unsweetened Coffee and Tea, Bone Broth, and zero-sugar Electrolyte Drinks. Homemade lemonades with keto-approved sweeteners are also an option.

| Erythritol/Allulose | Negligible | Low | Low | Baking, homemade drinks | Potential digestive issues in high doses |

| Maltitol | High | High | High | Avoid | Raises blood sugar; significant digestive upset |
