Make tracking
feel simpler.
Plain answers for the moments that usually make food logging annoying: rough estimates, changing portions, protein goals, and choosing what to track.
Most food logging problems are ordinary: missed meals, late-night snacks, weekends that vanish from the average, protein targets, shaky AI estimates, a stalled scale, or a tracker that adds more work than it removes. Use this map to pick the page that matches the job.
You have not started tracking yet.
A first-week plan: log what you already eat before changing anything, weigh only the calorie-dense foods, and set a target from your own data in week two.
Read the starting guide Maintenance caloriesYou are trying to work out maintenance.
Use a TDEE calculator as a starting estimate, choose one activity multiplier, then test it with complete logs and a weight trend.
Estimate maintenance Weight trend methodThe calculator and your scale disagree.
Use logged intake and a multi-week weight trend to work out the maintenance your own data implies, and what to check when the two numbers separate.
Use the trend method Weekend auditWeekends may be hiding the deficit gap.
Compare weekday and weekend logs, check drinks, restaurants, snacks, and late nights, then fix one repeat source.
Audit the weekend Recovery guideYou went over calories today.
Log the day, compare the weekly context, avoid harsh compensation, and restart at the next meal.
Recover calmly Plateau guideThe deficit is not showing on the scale.
Audit the log, scale window, restaurant estimates, water-weight context, and maintenance estimate before changing calories.
Troubleshoot the plateau Protein app choiceYou want protein visible without obsession.
Choose protein-only tracking, macro context, label-first logging, saved meals, or a lighter journal before installing another app.
Find the protein fit Estimate reviewAn AI number needs a sanity check.
Review macro math, portion confidence, oil, sauces, toppings, drinks, labels, and whether the entry stays editable.
Check the estimate App choiceThe tracker style is the problem.
Compare text, photo, voice, barcode, database search, privacy, and paywall friction before installing another app.
Find the fitDatabase search takes time, photo estimates need review, paywalls can hide the useful feature, and different meals need different inputs. Use this map to avoid reading five similar pages when one page answers your question.
