You track your meat. You track your vegetables. You track your olive oil. And then you drizzle a spoonful of ketchup, and it turns out that ketchup is 4 g of pure sugar. Hidden carbs are the number-one reason apparently 'perfect' keto weeks stop producing results.
The worst offenders
- BBQ sauce: 12–18 g carbs per 2 tbsp — often more than a slice of bread
- Ketchup: 4 g carbs per tbsp
- Teriyaki and hoisin sauce: 8–15 g per tbsp
- Balsamic vinegar (aged): 2–4 g per tbsp
- Most commercial salad dressings: 3–8 g per 2 tbsp
- Coffee creamer (flavored): 5–10 g per tbsp
- Marinara / pasta sauce: often contains added sugar
- Sausages and deli meats: often bulked with corn syrup or dextrose
Sneaky 'keto' products
- Keto breads bulked with modified wheat starch (spikes blood sugar)
- Fat bombs made with maltitol
- Protein bars with hidden inulin or isomalto-oligosaccharides
- 'Zero-carb' tortillas with resistant starch that still affects glucose in some
Places carbs hide in restaurants
- Marinades on grilled meats (often sugared)
- Fry-line oil shared with breaded items
- 'Blackened' seasoning blends with sugar
- Broths and soups thickened with starch
- Aioli and 'special sauces' with added sugar
The three-question filter
- Does it have a nutrition label? If yes, read it.
- Does it come from a restaurant? Ask how it's made.
- Is it a sauce, marinade, dressing, or breading? Assume there's sugar until proven otherwise.
