CARB COUNTS BY SERVING SIZE
| Serving | Net Carbs | Total Carbs | Calories | Notes |
|---|---|---|---|---|
| 1/4 tsp (≈1g) | ~0g | ~0.8g | ~3 | Often enough to thicken a smoothie or stabilize a cold sauce. |
| 1/2 tsp (≈2g) | ~0g | ~1.5g | ~7 | Good starting point; increases thickness quickly. |
| 1 tsp (≈3g) | ~0g | ~2.3g | ~10 | For thicker cold recipes; may be too much for sensitive stomachs. |
| 1 Tbsp (≈9g) | ~0g | ~7.0g | ~30 | Very large amount—more likely to cause GI and texture issues. |
WHY IT'S KETO-FRIENDLY
- Net carbs are effectively zero because the carbs are fiber
- Thickens without cornstarch or flour—useful for low-carb cooking
- Works especially well in cold recipes where you want creamy texture
- Used in tiny amounts, so it’s easy to fit into keto macros
- Can improve texture in keto ice cream and shakes
HEALTH BENEFITS
- Adds soluble fiber (though typical servings are small)
- Can make drinks and desserts more filling by increasing thickness
- Helps replace starch thickeners, which may help keep blood sugar steadier
- Useful for gluten-free and low-carb cooking when texture is challenging
HOW TO USE IT ON KETO
- Use a tiny amount—start with 1/8 tsp and increase if needed.
- Blend it in to avoid clumps; guar gum can clump when added all at once.
- Great for cold recipes: smoothies, keto ice cream, and chilled sauces.
- For hot sauces and gravies, some people prefer xanthan-gum—test both.
- If you get GI symptoms, reduce the dose or switch to gelatin/psyllium-husk.
PREPARATION SUGGESTIONS
THICKER SMOOTHIE
Add a pinch of guar gum while blending a smoothie for a thicker, milkshake-like texture.
KETO ICE CREAM
Use a very small amount in homemade ice cream bases to reduce iciness and improve scoopability.
COLD KETO SAUCE
Whisk into yogurt-based sauces or dips for a thicker consistency without added starch.
PROTEIN SHAKE UPGRADE
Blend a protein-shake with ice and a pinch of guar gum for a creamier texture.
CHILLED CHOCOLATE PUDDING
Combine cocoa, sweetener, milk/cream, and a tiny amount of guar gum; chill until thick.
GUAR GUM ON KETO: FAQ
Is guar gum keto-friendly?
Yes. In typical servings, guar gum is effectively ~0g net carbs because it’s mostly fiber and used in tiny amounts.
Guar gum vs xanthan gum: which is better?
Both are keto-friendly thickeners. Many people prefer guar gum for cold recipes (smoothies/ice cream) and xanthan-gum for sauces and dressings, but it depends on the recipe.
Does guar gum have carbs?
It has total carbs, but they’re largely fiber, so net carbs are close to zero in real serving sizes.
How much guar gum should I use?
Start with 1/8 tsp, blend, and add more only if needed. A little goes a long way.
What can I use instead of guar gum on keto?
Depending on the recipe: xanthan-gum, gelatin, psyllium-husk, or chia seeds. Avoid cornstarch if you’re strict keto.
Can guar gum kick you out of ketosis?
Unlikely. Net carbs are typically near zero at realistic servings, but track if you use large amounts.
