A regular bagel is one of the carbiest things in the bread aisle, so “keto bagel” products lean hard on added fiber, wheat protein or almond flour. We compared the current panels for bagels whose nutrition fields are all sourced, ranked by ketoside net carbs (never by price). Watch the serving sizes: they range from a 46 g bagel thin to an 89 g almond-flour bagel.

Net carbs here = total carbohydrate minus fiber, minus allulose and erythritol in full, minus half of other sugar alcohols such as maltitol. Glycerin is not subtracted. “Net carbs” isn’t a term the FDA defines, and the American Diabetes Association recommends counting total carbs, so we show both. How we calculate net carbs.

Full bagel table

None of these bagels lists sugar alcohols, so ketoside net carbs = total carbs minus fiber. ThinSlim Foods and Great Low Carb Bread Co. are sold online. [1], [3]

What makes a bagel “keto” (and what to check on the label)

• Serving size. Thomas’ Keto Bagel Thins are 46 g, a bagel thin rather than a full bagel. UNBUN’s are 87–89 g. Compare net carbs per bagel and per gram. [2], [5]
• Wheat starch. Thomas’, ThinSlim and Great Low Carb are flagged for wheat starch in our data; UNBUN is not (almond-flour based and grain-free). [2], [1], [3], [5]
• “0 g net carbs.” ThinSlim’s 0 g is 14 g total carbs minus 14 g fiber. US labels round each line to the nearest gram, and less than 0.5 g may be shown as 0 (21 CFR 101.9), so the true figure can be slightly above 0. [1]
• Label age. The Great Low Carb sesame bagel label comes via an online reseller and predates the 2020 Nutrition Facts format. [3]

Where to buy (Costco, grocery, online)

In our checks (Oct 19, 2026):

• Costco: we found no low carb bagel on costco.com or any official Costco page.
• Grocery: Thomas’ Keto Bagel Thins are listed at Fry’s Food Stores (a Kroger banner), but the page showed pickup and delivery unavailable, so in-store availability is uncertain. UNBUN is listed at Whole Foods. [2], [5]
• Online: ThinSlim Foods ($9.49 for 6 as of Oct 19, 2026; ships to the lower 48), UNBUN direct (frozen shipping; sold out Oct 19, 2026), and Great Low Carb sesame bagels via Lo Carb U (out of stock Oct 19, 2026). [1], [6], [3]

How we check

Each product record links to the nutrition panel we used (retailer or brand page), with the store and price where we checked one, and the date we checked it. We only list products whose required fields are all sourced; anything else stays off the tables until it is. Where sources conflict, we say which one we used. We haven’t taken our own label photos yet; that waits on a US tester. We re-check labels at least every 28 days.
