Can AI Calculate My Macros Accurately? The Science Explained

The Harris-Benedict Flaw
Most online calculators use the Harris-Benedict equation from 1919. It guesses your BMR based on age, height, and weight. It is wrong for 60% of the population. Why? It ignores muscle mass. Two people weighing 180lbs can have wildly different caloric burns if one is 10% body fat and the other is 30%.
The AI Solution: Dynamic TDEE
Instead of a static guess, AI solves for X. It looks at your Caloric Intake (Input) vs. Weight Trend (Output) over 14 days. The difference is your actual TDEE (Total Daily Energy Expenditure). No guessing. Just math.
Why "Activity Levels" Are A Trap
Selecting "Moderately Active" usually overestimates your burn by 300-500 calories. MyMacroLearning recommends setting your profile to "Sedentary" and letting your Apple Watch / Wearable add back verified active calories.
