WHY IT'S KETO-FRIENDLY
- No net carbs: absorbed but minimally metabolized, so it doesn’t spike glucose/insulin
- Sugar-like function and texture: excellent 1:1-ish swap in many recipes
- Very low calorie (~0.4 kcal/g) supports weight management
- No impact on ketosis when used in reasonable amounts
HEALTH BENEFITS
- Does not raise blood glucose or insulin—helps maintain ketosis
- May modestly aid insulin sensitivity and post-meal glucose control
- Low-calorie sugar alternative that can reduce overall sugar intake
- Often well tolerated in small–moderate amounts
PREPARATION SUGGESTIONS
KETO BAKING SUBSTITUTE
Use as a near 1:1 sugar replacement in cakes, cookies, and muffins; it browns and caramelizes similarly.
SWEETEN BEVERAGES
Dissolves in hot or cold drinks—perfect for black-coffee or green-tea.
SAUCES AND SYRUPS
Simmer with water (and a pinch of xanthan gum if desired) for glossy, sugar-free syrups and glazes.
HOMEMADE ICE CREAM
Prevents iciness and keeps keto ice cream scoopable compared with many other sweeteners.
