How to Start Counting Calories: A Beginner's Guide (2026)

Calorie counting has a reputation for being tedious — mostly because people start wrong. This guide shows the low-friction way to begin and keep going.

Step 1: Find Your Starting Number

Use a calorie calculator to estimate your maintenance calories (based on age, weight, height and activity), then subtract 15–20% for a steady weight loss of ~0.5 kg per week. Don't cut more — aggressive deficits are why most diets collapse by week three.

Step 2: Log Everything for the First 7 Days (Even Badly)

The first week's goal is awareness, not precision. Log every meal, snack and drink. Most people discover 300–500 kcal per day they didn't know about — coffee drinks, sauces, "just a bite" grazing.

Step 3: Make Logging Fast

• 📸 Log meals by photo — AI estimates calories and macros in seconds
• 💬 Type what you ate in plain language
• 🔖 Repeat logs for your usual breakfasts (you eat the same 10–15 meals most weeks)

Step 4: Set a Protein Floor

Aim for 1.6–2 g of protein per kg of body weight. Protein keeps you full, protects muscle in a deficit, and makes the same calories far more satisfying. Kcalibra tracks this automatically next to your calories.

Step 5: Judge Weeks, Not Days

A single high-calorie day doesn't ruin anything. What matters is your weekly average. Check your weekly report, adjust by 100–200 kcal, and continue.
