Direct Answer
Your TDEE is maintenance calories — eat there to hold weight. For fat loss, eat TDEE minus 300-500; for muscle gain, TDEE plus 200-300. If TDEE is 2,000, try 1,500-1,700 to lose ~1 lb/week.
Use the TDEE Calculator then apply your goal offset.

What to Do With Your TDEE
| Goal | Calorie target |
|---|---|
| Maintain | TDEE |
| Lose ~0.5 lb/wk | TDEE − 250 |
| Lose ~1 lb/wk | TDEE − 500 |
| Lean bulk | TDEE + 250 |
Understanding the Three Numbers on Your Calculator Output
Most TDEE (total daily energy expenditure) tools show three targets:
- Maintenance (TDEE): eat here to hold weight steady
- Deficit target: TDEE minus 250 to 500 for fat loss
- Surplus target: TDEE plus 200 to 300 for lean muscle gain
BMR (basal metabolic rate) is the at-rest component inside TDEE — never eat at BMR long-term unless a clinician directs it.
Worked Example: TDEE 2,000 — All Three Goals
Assume your calculator returns TDEE 2,000:
| Goal | Daily calories | Expected outcome |
|---|---|---|
| Maintain | 2,000 | Weight stable over 2-4 weeks |
| Lose ~1 lb/week | 1,500 | ~500 cal/day deficit |
| Lean bulk | 2,250 | ~0.5 lb/week gain |
Protein first: at 160 lb target weight, aim 128 to 160g protein regardless of goal. Fill remaining calories with carbs and fat based on training volume.
How to Validate Your TDEE in 14 Days
- Weigh yourself each morning after bathroom, before food.
- Eat at calculated maintenance for 14 days.
- If weekly average drops, TDEE is higher — add 100 to 200 calories.
- If weekly average rises, TDEE is lower — subtract 100 to 200 calories.
- Do not adjust daily based on one scale reading — use weekly trends.
What to Do Next With Your TDEE
| If your goal is… | Start here | Adjust when… |
|---|---|---|
| Fat loss | TDEE − 500 | Loss exceeds 1.5 lb/week for 2+ weeks |
| Maintenance | TDEE | Weight trends up or down over 2 weeks |
| Muscle gain | TDEE + 250 | Gain exceeds 1 lb/week (likely fat) |
TDEE Action Checklist
- Run TDEE Calculator with honest activity level
- Pick one goal for 2–4 weeks minimum
- Set protein before carbs and fat
- Track weight trend, not daily noise
- Recalculate after 10–15 lb change
Common Mistakes After Getting Your TDEE
Switching goals weekly prevents learning true maintenance. Give any target 2 to 4 weeks before changing calories. Another error is adding full exercise calories on top of a TDEE that already includes activity level.
Using scale weight alone ignores water fluctuation — 2 to 5 lb daily swings from sodium and carbs are normal. Weekly averages reveal real trends.
Assumptions and Limitations
TDEE calculators estimate average metabolism with ±10% to 15% individual variance. Thyroid disorders, PCOS, medications, and chronic stress alter burn rate. Wearable calorie estimates are often inflated — use them for step trends, not food targets.
Pregnancy, adolescence, and clinical underweight require professional guidance, not self-calculated deficits.
What This Means for Your Personal Numbers
Generic examples help you understand the logic — your outcome depends on inputs only you know. Run the related calculator with your age, weight, income, loan amount, or location before treating any table row as a target. Adjust one variable at a time so you can see which lever moves the result most.
If the calculator output surprises you, verify assumptions first: activity level, tax district, insurance quote, cycle length, or credit tier. Small input changes often move results more than rounding differences between published benchmarks and your situation.
When numbers still look wrong after honest inputs, use 2 to 4 weeks of tracking — weight trend, home readings, spending log, or rate quotes — to calibrate. Calculators start the conversation; your data confirms it.
Calculator Methodology
The TDEE Calculator uses Mifflin-St Jeor BMR multiplied by activity factor (1.2-1.9) and optional goal offsets.
Assumptions: Honest activity selection; average metabolism.
Limitations: Individual variance ±10-15%; adjust using 2-4 week weight trends.
How to stress-test your result
Run a best case and worst case input side by side. For health calculators, shift activity one level up or down. For finance calculators, add 0.25% to rate or 10% to tax and insurance. If the outcome breaks your budget or health target at the worst case, build margin before committing.
Document the date you ran the numbers and which source you used for tax, insurance, or clinical thresholds. Re-run when your inputs change materially — new job, new prescription, rate lock, or 10+ lb weight change.

Frequently Asked Questions
What is TDEE?
TDEE (total daily energy expenditure) is the calories you burn in 24 hours including BMR, digestion, movement, and exercise. It equals maintenance calories — eat at TDEE to maintain weight. Calculators estimate TDEE as BMR times an activity multiplier. Actual TDEE varies ±10% to 15% due to genetics, NEAT, and tracking error.
What should I eat if my TDEE is 2,000 calories?
Eat 2,000 to maintain, 1,500 to 1,700 to lose ~1 lb/week, or 2,200 to 2,300 to gain muscle slowly. Set protein first (0.7 to 1g per pound target weight), then fill carbs and fat. Track weight 2 to 4 weeks — if loss is too fast or slow, adjust by 100 to 150 calories, not a full recalculation daily.
My TDEE seems too high or low — what now?
Treat calculator output as a hypothesis. Eat at the estimated maintenance for 14 days while weighing daily — trend weight should be flat. If you gain, TDEE is lower; if you lose, TDEE is higher. Adjust by 100 to 200 calories. Wearable calorie burn is often inflated — do not add full exercise calories on top unless weight trends require it.
TDEE vs BMR: Which do I eat above?
Never eat at BMR long-term — BMR is organs-at-rest burn. TDEE is your eating target for maintenance. Deficits subtract from TDEE, not BMR. A BMR 1,400 / TDEE 2,000 person eating 1,400 is a 600-calorie deficit (aggressive), not maintenance.
How often should I recalculate TDEE?
Recalculate after every 10 to 15 pounds lost or gained, or when activity level changes significantly. Smaller adjustments (100 cal) handle plateaus between recalculations. Age and muscle changes slowly — monthly recalculation is enough unless you are in rapid weight change.
Maintenance vs deficit TDEE: Same calculator?
Yes — same TDEE estimate. Deficit and surplus are TDEE minus or plus 250 to 500 calories. The TDEE Calculator may show all three targets. Pick one goal for 2 to 4 weeks minimum before switching — program hopping prevents learning your true maintenance.
