Keto Mode

Added sugar limited, fibre kept up, and net carbs tracked against a 25 g limit on the phone

5 min readUpdated Sep 2, 2026

Listed as Keto on the web and Keto/Low-Carb on the phone. For people limiting carbohydrate enough to run on fat.

What applying it changes

Your recommendations are rebuilt with:

  • Foods flagged for added sugar on the foods-to-limit list.
  • A fibre target of 25 to 38 g a day, so fibre still comes from non-starchy vegetables.
  • Saturated fat is not limited, because a keto diet expects it. Everything your labs, conditions and allergies already decide still applies.

    Net carbs

    Net carbs are total carbohydrate minus fibre. The phone's limit is 25 g of net carbs a day, and every keto figure on the phone uses that one number.

    The phone screen

    Open the mode from Diet Modes. The Keto Mode screen shows:

  • Today's Macros: net carbs against the 25 g limit, reading Within keto limit or Over keto limit, with fat and protein alongside.
  • Weekly Net Carbs: one bar per day for the week.
  • Keto-Friendly Foods: staples with their net carbs and fat per serving; tap one to search the food database for it.
  • Signs of Ketosis: the common changes as your body adapts. This is information, not a measurement.
  • Keto Tips.
  • Track with Labs: tap Upload to add blood work so cholesterol and blood sugar are watched while you are on keto.
  • The Carb Tracker

  • Under Trackers, tap Carb Tracker.
  • Today’s Macro Ratio shows how today's grams split between net carbs, fat and protein. Before you log anything it shows the target split of 70% fat, 25% protein and 5% carbohydrate.
  • Macro Breakdown shows net carbs against 25 g, and fat and protein against targets sized from today's calories at that split. Going over the carb limit is called out in grams.
  • Under Check a Ketone Reading, type a blood-ketone value from your meter in mmol/L to see which band it falls in: not in ketosis below 0.5, light ketosis to 1.0, optimal from 1.0 to 3.0, high to 5.0, and dangerously high above that. Readings are not saved; there is nowhere yet for a ketone log to go.
  • On the web

    The web applies the mode and shows the rebuilt recommendations. Net-carb tracking is phone-only.

    What it does not do

    There is no ketone log, no meter integration, no electrolyte prescription and no strict or moderate keto setting. The 25 g limit is the same for everyone.
