What Is Calories per Meal?
Definition
Adult total daily expenditure runs 1,800-2,600 kcal by activity; the 3:4:3 meal split gives ~500 kcal breakfast, 700 lunch, 500 dinner (on a 2,000 kcal day). Reference items: a bowl of rice (150g) ≈175 kcal, stir-fried greens (15g oil) ≈180 kcal, braised pork 100g ≈470 kcal, full-sugar milk tea 450-550 kcal, a burger combo 1,000-1,200 kcal. Fat-loss math: a 300-500 kcal daily deficit trims 0.3-0.5 kg weekly — one 1,200 kcal hotpot combo erases two days of deficit.
Formula
Per meal ≈ TDEE × 30% (breakfast) / 40% (lunch) / 30% (dinner)
Worked Example
A ~550 kcal cut meal: 100g multigrain rice (115), 120g steamed chicken breast (130), 200g blanched broccoli (70), 5g olive oil (45), seaweed-egg soup (60), one 150g apple (80).
Common Misconception
"Skip dinner for fast loss" — skipping cuts adherence, not fat; most people compensate at night. "Zero-sugar drinks are free" — sweeteners carry no calories but may prime appetite; population data show no weight advantage. And "salad is low-cal" — two spoons of dressing (80-150 kcal each) can exceed the greens.
