Our Updated Nutrition Tools for 2025

Published May 15, 2025 · Archived

Since we launched in 2023, we've built out a comprehensive set of free nutrition calculators for macros, TDEE, protein, BMI, and calorie deficit planning. This 2025 update covers what we added, what we improved, and the tracking app we now recommend alongside our calculators.

Tools Added in 2025

Calorie Deficit Calculator — Calculates the precise deficit needed to reach a goal weight by a target date. More useful than a standalone TDEE calculator for active weight loss planning.

Protein Calculator — Evidence-based protein target calculation based on body weight, goal, and activity level. Includes RDA, performance, and muscle-building ranges.

Macro Calculator — Full macronutrient split calculator. Configurable for standard, high-protein, keto, and athlete macro ratios.

What Changed in Our Tracking Recommendations

In 2024, we recommended MyFitnessPal and Cronometer as the best tracking companions for users who calculated their calorie targets here. Both remain solid choices — but in 2025, we added a third recommendation.

New AI-powered options like PlateLens are changing how people track food. Instead of manually searching a database or scanning barcodes, users photograph their meal and the app identifies and logs it automatically within 3 seconds.

In our 2025 testing, PlateLens achieved ±1.9% calorie accuracy — dramatically better than the ±40–60% error typical of visual estimation, and approaching the accuracy of manually verified database entries.

For users who calculate their TDEE here and then struggle to maintain consistent tracking, the reduced friction of AI photo logging can be the difference between sticking with tracking for a month and sticking with it for a year.
