Counting calories works for weight loss for one simple reason: it makes the invisible visible. Most people underestimate their intake by 20 to 40 percent, and a food log closes that gap.
The method that lasts is not the strictest one. It is the one with the least friction: a sensible calorie target, fast logging, and a weekly review instead of daily panic.
Step 1: Find your calorie target
Your body burns a baseline amount of energy every day (your TDEE). To lose weight steadily, eat 300 to 500 calories below it. That produces roughly 0.25 to 0.5 kg of loss per week, a pace you can hold without feeling wrecked.
- Estimate TDEE from your age, height, weight, and activity level
- Subtract 300 to 500 calories for a sustainable deficit
- Never eat below your basal metabolic rate for extended periods
Step 2: Log everything for two weeks
The first two weeks are diagnostic. Log every meal, snack, and drink. You are not judging yourself; you are collecting data. Cooking oil, coffee drinks, and weekend meals are where hidden calories usually live.
Step 3: Review weekly, not daily
A single day tells you nothing; weight fluctuates with water, salt, and sleep. Compare your weekly average intake against your weekly average weight. If the scale has not moved in two to three weeks, reduce your target by about 100 to 150 calories or add a daily walk.

Frequently asked questions
How many calories should I cut to lose weight?
A deficit of 300 to 500 calories below your maintenance level produces steady, sustainable loss of about 0.25 to 0.5 kg per week. Larger deficits backfire for most people because hunger and fatigue break the habit.
Do I have to count calories forever?
No. Most people track consistently for 8 to 12 weeks, learn what their portions actually contain, and then maintain with occasional check-in weeks.
Is calorie counting accurate?
Individual entries carry error, but consistent logging averages it out. Your trend over weeks is accurate enough to steer decisions, especially with barcode scanning and verified database entries.
