Best Site for Nutrition Tracking
Summary
The best nutrition tracking site is MacroFactor for users serious about body composition — algorithmic calorie target adjustment based on actual weight trend beats static targets. Cronometer is the right pick for accurate micronutrient tracking, using the NCCDB government database rather than user-submitted entries. MyFitnessPal dominates by user base but its post-Under Armour sale to Francisco Partners in 2020 led to subscription gating of features that were previously free. LoseIt! remains a polished alternative. We rank by data accuracy and incentive alignment rather than user-base size.

Frequently asked questions
What changed at MyFitnessPal after the 2020 sale?
Under Armour sold MyFitnessPal to Francisco Partners (a private equity firm) in October 2020. Subsequent product direction moved features that had been free behind paid Premium tier. The 2022 barcode-scanning paywall was the most-visible change. The trajectory has been toward subscription monetization rather than free utility, which the user base has largely accepted as the new reality.
Why is MacroFactor's adaptive target different?
Most calorie trackers use a static formula (Harris-Benedict, Mifflin-St Jeor) to set a target based on age, weight, sex, activity level. MacroFactor instead observes your actual weight trend over weeks and adjusts the calorie target to deliver the planned rate of change. This accounts for the fact that the standard formulas are wrong for many individuals — usually by 200-500 calories.
Are nutrition apps accurate?
Database accuracy varies. Cronometer using verified government databases is most accurate. User-submitted databases like MyFitnessPal have many incorrect entries — verify items if precision matters. Restaurant and packaged foods generally accurate; home-cooked meals require accurate weighing of ingredients.
Is tracking my food worth it?
For weight management, yes — studies consistently show food logging improves outcomes regardless of methodology. For micronutrient adequacy on restrictive diets, yes — Cronometer specifically. For general healthy eating without specific goals, often not worth the friction long-term.
What about food sensitivity or allergy tracking?
MyFitnessPal and Cronometer support tagging but neither specializes. For sensitivity tracking, dedicated tools like mySymptoms or written food-symptom journals work better. Don't expect general-purpose calorie trackers to handle complex elimination diets.
