Got it. Trenton will get back to you with your numbers within 72 hours.
The numbers are the easy part. Where most people stall is actually hitting them week after week, then knowing when and how to adjust as their body responds.
Calculations use Mifflin-St Jeor (or Katch-McArdle when body fat % is provided), net MET-based exercise calorie estimates (MET−1 to avoid double-counting BMR during activity), additive NEAT (job baseline + step-driven movement scaled to body weight), and protein-aware TEF (~25% for protein, ~8% for carbs, ~3% for fat). Deficits are capped at 25% of TDEE for safety. Educational tool only, not medical advice. Talk to a medical professional before starting a diet. Medical disclaimer

Find your real TDEE (recalibrate)
Formulas estimate, your scale measures. Track your intake and weight for 2+ weeks, enter the numbers, and this computes the TDEE your body actually demonstrated. More accurate than any equation.
Negative = lost weight (e.g. -1.6), positive = gained.
Use at least 14 days, water weight lies over short periods.

Calculator FAQ
What is a TDEE calculator?
A TDEE (Total Daily Energy Expenditure) calculator estimates how many calories you burn in a full day, your BMR plus calories from non-exercise activity (NEAT), exercise (EAT), and digestion (TEF). This calculator goes further than most by asking about your job, steps, and exercise so it can estimate each component separately.
Why does this calculator ask about my job and steps?
Most calculators use a single "activity multiplier" that lumps job activity, daily movement, and exercise together. That's imprecise. A 200 lb construction worker who lifts 4×/week has very different energy needs than a 200 lb desk worker who lifts the same. By computing NEAT (job + steps) separately from EAT (exercise), you get a more accurate target.
How is my BMR calculated?
Without a body fat %, this calculator uses the Mifflin-St Jeor equation, the most accurate BMR formula for the general population. With a body fat %, it switches to the Katch-McArdle equation, which is more accurate for lean / trained individuals because it bases BMR on lean body mass.
