Weight loss & fat loss
Calorie deficit for fat loss: what works long term
Fat loss is mostly consistency in a moderate deficit—not the most extreme week you can white-knuckle once.
Deficit definition (no jargon)
You eat fewer calories than you burn on average; body fat is a common fuel source when protein and training protect muscle.
Estimate burn with TDEE basics, then subtract thoughtfully.
BMR and TDEE roles
BMR anchors resting needs; TDEE captures your real day. Deficits based on TDEE match lifestyle better than BMR-only shortcuts.
Macro suggestions
Higher protein often improves fullness and lean mass retention. Explore macro ratios for fat loss.
Maintenance strategy after fat loss
Reverse diet calories up toward maintenance; see maintaining after loss.
Sample deficit targets
Examples only.
| Food / context | Typical serving | Approx. kcal |
|---|---|---|
