Why Reading Labels is Essential on Keto
The keto diet focuses on minimizing carbs and maximizing fats. Even foods labeled as "low-carb" may contain sugars or starches that can kick you out of ketosis. This is why reading labels is a non-negotiable skill for anyone on a ketogenic lifestyle.

Where Hidden Carbs Lurk
Manufacturers often add small amounts of sugar, maltodextrin, or starch to processed foods. These might not seem like much, but over time they add up. Watch out for these common culprits:
- Low-fat products
- "Healthy" snacks
- Sauces, dressings, and condiments
- Protein bars and shakes

How to Decode Nutrition Labels
Focus on these areas of the label:
Total Carbohydrates
Always check the "Total Carbohydrate" section first. From here, subtract fiber and sugar alcohols (like erythritol) to get net carbs. This is the number that matters most on keto.
Ingredients List
Look for hidden sugars like dextrose, maltodextrin, and corn syrup. Even small amounts can impact insulin and kick you out of ketosis. For trusted keto foods, see our Top 10 Keto-Friendly Foods.
Serving Size
Don’t be fooled by the per-serving values. If the label says 2g of carbs per serving but the package contains 4 servings, you’re actually getting 8g if you consume it all.
Common Labeling Traps
Watch for marketing terms like "sugar-free" or "net-carb friendly." These often still include high-glycemic ingredients. For example, maltitol is labeled as a sugar alcohol but has a glycemic index close to sugar.
If you practice intermittent fasting with keto, accurate label reading is even more important for metabolic control.

FAQ
What are net carbs and why do they matter on keto?
Net carbs = Total carbs - fiber - sugar alcohols. These are the carbs that affect your blood sugar and ketosis.
Is maltitol keto-friendly?
Not really. Maltitol has a high glycemic index and can spike blood sugar, so it’s best avoided on keto.
Are all sugar alcohols safe on keto?
No. Erythritol and stevia are preferred, but others like sorbitol and maltitol may impact ketosis.
How do I know if a product is keto-friendly?
Check net carbs, ingredients list, and serving size. Use tracking apps to stay accurate.
