Everything Keto.
One App.

The ketogenic diet is a low-carb, high-fat way of eating that puts your body into ketosis. In ketosis, you burn fat for fuel instead of glucose. Most keto plans cap carbs under 20 to 50 grams a day, with 70 to 75% of calories from fat and 20 to 25% from protein. Healthy adults usually reach ketosis within 2 to 4 days at that carb level (Westman et al., 2007).

Eat: meat, poultry, fish, eggs, full-fat dairy, leafy greens, non-starchy vegetables, avocados, olive oil, nuts, seeds, and unsweetened drinks. Avoid: bread, pasta, rice, sugar, most fruit, beans, and starchy vegetables. The Restaurant Guide and Grocery Templates inside Keto Kit handle the day-to-day version of this.

Expect 2 to 10 pounds in the first week (mostly water), then 1 to 2 pounds of fat per week after that, assuming a moderate calorie deficit. A 2013 meta-analysis of randomised controlled trials found that very-low-carb ketogenic diets produced more long-term weight loss than low-fat diets (Bueno et al., British Journal of Nutrition). Individual results vary.

Watch for reduced hunger, mental clarity around day 4 to 7, a slight metallic or fruity breath, and steadier energy between meals. For a real number, use a blood ketone meter (0.5 to 3.0 mmol/L is nutritional ketosis, per Volek & Phinney's 2011 reference) or a breath ketone device. Keto Kit also estimates your ketosis likelihood from your logged macros and fasting state.

Yes. The core app is free forever, no credit card required. Free includes manual food search, barcode scanning, the intermittent fasting timer with 5 metabolic stages, the daily 0–100 Keto Score, gamification, and the restaurant guide. Premium ($5.99/month or $49.99/year) adds AI Photo Scan, Voice Food Logging, the Keto AI Coach, full access to the recipe library, batch barcode scanning, AI meal planning, advanced analytics, and an ad-free experience.

Four ways. Free covers manual search across a 500,000-item food database and barcode scanning. Premium adds AI photo recognition (snap a photo, AI identifies the dish and estimates portion) and voice logging in plain language ("had two eggs and bacon"). Most entries take under five seconds.

The Keto Score is a daily 0–100 rating of how close your day was to a keto target. It weighs net carbs, macro ratios, calorie targets, hydration, and logging consistency. 80 or higher means you nailed it for the day.

Yes. The built-in intermittent fasting timer tracks five metabolic stages: Fed, Transition, Fat Burn, Ketosis, and Autophagy. Fat-burning typically kicks in around the 8 to 12-hour mark as liver glycogen depletes (Anton et al., 2018, Obesity). Pick a preset window (12:12, 16:8, 18:6, 20:4, OMAD) or set a custom duration.

General macro trackers were built for any diet and added a low-carb preset later. Keto Kit was built for keto from day one. That means a keto-specific 0–100 score, a five-stage fasting timer, 1,000+ keto-only recipes, and an AI coach trained on keto questions. No general macro tracker offers any of that natively.

iOS (App Store) and Android (Google Play). Your data syncs automatically across every device you use.

Yes. Food logging, the fasting timer, your saved recipes, and your dashboard all work offline. AI photo recognition, the AI keto coach, and recipe browsing need a connection. Anything you log offline syncs the moment you reconnect.

Keto Kit is a tracking and education tool, not medical advice. A 2018 controlled clinical study found significant glycemic improvement at 12 months in adults with type 2 diabetes on a ketogenic care model (Hallberg et al., Diabetes Therapy). Even so, talk to a doctor before starting keto if you have any medical condition, especially type 1 diabetes, kidney disease, or pancreatitis. Keto Kit doesn't replace professional medical guidance.
