Calorie Counting for Weight Loss: A Practical Guide
Published Apr 14, 2026 Β· 6 min read
Weight loss comes down to one principle: eat fewer calories than you burn. But "just eat less" is terrible advice. Here's the practical, sustainable approach to calorie counting that actually works long-term.
Step 1: Find Your TDEE
Total Daily Energy Expenditure (TDEE) is how many calories you burn per day including all activity. For most adults:
| Activity Level | TDEE Multiplier | Example (BMR 1,600) |
|---|---|---|
| Sedentary (desk job) | BMR Γ 1.2 | 1,920 cal |
| Lightly active (1-3 days exercise) | BMR Γ 1.375 | 2,200 cal |
| Moderately active (3-5 days) | BMR Γ 1.55 | 2,480 cal |
| Very active (6-7 days) | BMR Γ 1.725 | 2,760 cal |
Step 2: Set Your Deficit
- Moderate deficit (500 cal/day): ~1 lb/week loss. Sustainable. Recommended.
- Aggressive (750-1,000 cal/day): ~1.5-2 lbs/week. Harder to maintain. Risk of muscle loss.
- Never go below: 1,200 cal (women) or 1,500 cal (men) without medical supervision.
A 500-calorie deficit seems small, but that's 3,500 calories per week β roughly one pound of fat.
Step 3: Track Accurately
- Use a food scale for portions β eyeballing is wildly inaccurate
- Log cooking oils, sauces, and drinks (a tablespoon of olive oil is 120 calories)
- Track consistently for at least 2 weeks before adjusting
- Weigh yourself daily at the same time; track the weekly average, not day-to-day fluctuations
Common Mistakes
- Too aggressive: Cutting 1,000+ calories leads to bingeing cycles
- Eating back exercise calories: Fitness trackers overestimate by 30-50%
- Weekend amnesia: Two "cheat days" can erase a week of deficit
- Ignoring protein: Low protein + calorie deficit = muscle loss
When to Stop Counting
Calorie counting is a tool, not a lifestyle. Use it for 3-6 months to build portion awareness, then transition to intuitive eating with periodic check-ins. If counting triggers anxiety or disordered eating patterns, stop immediately and consult a professional.
