Keto lives or dies on one number: net carbs. But labels bury it, restaurant meals hide it, and "low-carb" marketing lies about it. This scanner answers the only question that matters — is it keto? — with a verdict, the net-carb math, and the why, in seconds. Free, in your browser, no app.
A food is generally keto-friendly at 5g or fewer net carbs per serving — net carbs = total carbs minus fiber. Meat, eggs, cheese, butter, leafy greens, and most cooking oils are keto; bread, pasta, rice, potatoes, and sugary foods are not. Get an instant verdict with net carbs explained at foodidentifier.com — free, no app, no account.
The 5g-per-serving rule of thumb works because most keto approaches target roughly 20–50g of net carbs per day — a single 30g-carb item can blow half the budget in one sitting. Where people get surprised: sauces and dressings (sugar hides in "savory" foods), "keto" packaged snacks that pad the count with questionable fibers, fruit (berries in small amounts can fit; bananas and grapes rarely do), and restaurant cooking (glazes, breading, sugary marinades). The scanner shows the full breakdown — total carbs, fiber, and the resulting net carbs — so the verdict comes with evidence, not just a yes/no.
Why a scanner beats a keto list: static "is it keto" lists can't cover your specific restaurant dish or your grandmother's recipe. FoodIdentifier identifies the actual food in front of you and computes net carbs for it — including the traps lists never mention.

Net carbs = total carbohydrates minus fiber (and usually minus certain sugar alcohols). They're the carbs that meaningfully affect blood sugar — the number keto counts.
Most keto approaches target roughly 20–50g of net carbs per day. Staying under your personal limit matters more than any single food's verdict — this is general information, not medical advice.
Most fruit isn't, but small portions of berries (raspberries, blackberries, strawberries) can fit a daily budget. Bananas, grapes, mangoes, and dried fruit rarely do. Scan your portion to check.
Some are, many aren't — labels use generous fiber math. Scan or check the label's net carbs yourself rather than trusting the front of the package.
Yes — photograph the dish and the AI estimates the foods and portions, including likely hidden carbs from sauces and breading. Treat it as a smart estimate, not a lab test.
No. FoodIdentifier runs in your browser on iPhone, Android, desktop, or tablet.
No — it's an informational nutrition tool. If you manage diabetes or another condition, talk to your doctor before starting keto.
