The Deficit vs Calorithm

Understand your calorie balance. Log food your way. The Deficit brings your calorie intake, energy expenditure and progress together in a clear daily overview, using Apple Health data from the apps and devices you already use. SEE THE BIG PICTURE • Follow your calorie balance across days and custom date ranges. • See intake, macros, resting and active energy, and exercise. • Set a goal and compare your estimated progress. Days with incomplete intake can be excluded from the balance calculation. AGENTIC FOOD TRACKING — OPTIONAL, EFFORTLESS Tell the AI agent what you eat and it logs the meal for you. Dictate foods and amounts, or photograph a nutrition label and say or type “Log 200 g of this food.” The agent reads the label, calculates the portion and adds it to your diary. When you do not know the portion, it can estimate it for you to review and adjust. • Log meals by typing, dictating or taking a photo on iPhone or iPad. • Log multiple meals at different times in one request. • Dictate food and review your diary directly on Apple Watch. • Ask follow-up questions in chat or start a live voice conversation. • Add a personal coaching goal for more relevant feedback. • Review and edit portions and nutrition values. • Reuse familiar foods from your food memory. • Keep your diary and conversation in sync across iPhone, iPad and Apple Watch. • Start dictation with Shortcuts or the Action Button on supported devices.
