Sustainability & sensitivities Each meal scan includes estimated CO₂e (carbon footprint) so you can see environmental impact over days and weeks. Packaged items can display a gluten status indicator for quick screening. Insights inform—never judge. Always know what to do next A clear, always-visible calorie deficit view translates energy balance into plain language: how far you are from goal, what's driving the current trend (intake, activity, fasting), and the smallest effective changes to close the gap. On-budget notifications help you course-correct early. Syncs when you do—works even if you don't Fitness tracker & connected scale sync: steps, workouts, heart-rate-based estimates, and weigh-ins automatically. No tracker or smart scale? Manual weight entry. Choose from 60 activity types (from walking meetings to HIIT) to estimate calories burned—so your budget reflects your real day. Fast logging without scanning Use the Calorie Estimator with 60 predefined foods to compute intake quickly. Each item includes a simple carbon-footprint range (low / medium / high) and gluten status. Evidence-based under the hood Energy balance is the primary driver of weight change. Trend smoothing reduces day-to-day noise (hydration, sodium, timing).
