How many calories should I eat to lose weight?
The honest answer starts with your maintenance burn (TDEE), then subtracts a modest deficit you can keep for months—not the smallest number you can tolerate for a week.
Introduction: weight loss is an average, not a single day
Fat loss happens when you eat fewer calories than you burn, averaged over time. The “right” intake depends on body size, activity, medical context, and how aggressive you can be without losing sleep, strength, or control around food.
Jump straight to our weight-loss preset calculator for a guided estimate, then read how to calculate calories for weight loss for a worksheet-style breakdown.
A practical method most people can follow
1) Estimate maintenance (TDEE)
Use stats-based calculators as a starting guess. If you already track food and weight, you can infer maintenance from recent averages—often faster than theory alone.
2) Choose a deficit size
Common starting bands are roughly 250–500 kcal/day under maintenance for many adults, but smaller bodies or high stress may suit gentler deficits. Listen to energy, hunger, and training quality—not only the scale.
3) Reassess every 2–3 weeks
Compare weekly average weight to the prior weeks. If progress is flat, confirm tracking accuracy before slashing another 500 kcal. Sometimes a 100–150 kcal nudge plus more steps is the smarter move.
Example math (illustrative)
If TDEE ≈ 2,600 kcal, a 450 kcal deficit targets ~2,150 kcal/day. Over a week, 450 × 7 ≈ 3,150 kcal—roughly in the ballpark people associate with ~0.45 kg fat tissue, though water masks short-term changes.
Macros and adherence
Protein and fiber make deficits easier to tolerate. If you enjoy lower-carb days, map calories into the keto macro preset; if you prefer higher carbs around workouts, read macro basics for fitness for balance without dogma.
What a day near 2,000 kcal might include (examples only)
Portions vary—use a food scale when possible.
| Food / context | Typical serving | Approx. kcal |
|---|---|---|
| Greek yogurt + berries + granola | breakfast | ~350–450 |
| Turkey sandwich + apple | lunch | ~500–650 |
| Stir-fry chicken + rice + veg | dinner | ~600–750 |
| Latte + small chocolate | snacks | ~200–300 |
Values are rounded planning estimates—check labels for your brand.
Common weight-loss calorie mistakes
- Copying a friend’s intake without scaling to your size and activity.
- Equating slow progress with failure—half a kilogram per week is great for many.
- Ignoring weekends that erase weekday deficits.
- Skipping medical guidance when pregnant, underweight, or on glucose-lowering meds.
Sustainable tips
- Prioritize protein at each meal; see daily protein intake for anchors.
- Add steps before you slash food again—walking supports adherence.
- Keep a consistent meal rhythm if grazing triggers overeating.
- Return to the homepage calculator after every ~5% body weight change.

Quick answers
These short Q&As mirror the FAQ structured data on this page for transparency.
- How many calories should I eat to lose 0.5 kg per week?
- It varies by TDEE. A common approach is a moderate daily deficit guided by trend weight; very rough weekly energy gaps near ~3,500–3,900 kcal are often discussed, but individual results differ.
- Is 1,200 kcal safe for everyone?
- No. Small bodies and sedentary contexts differ from taller, active adults. Very low intakes risk nutrient gaps—professional supervision matters.
- Should I eat back exercise calories?
- Be conservative—wearables overestimate burn. If performance or periods suffer, raise intake slightly and monitor trends.
- Do I need keto to lose weight?
- No. Ketogenic diets control appetite for some people, but total calories still drive fat loss.
- What if I plateau?
- Verify tracking, sleep, and stress; then adjust intake or activity modestly. Plateaus are normal—patience plus precision wins.
- Where can I start calculating?
- Use our free tools from the homepage and the dedicated weight-loss preset, then refine using your own weight trend.
