Why count calories

Calorie counting is the most reliable method for weight loss. Without tracking, we underestimate our intake by 20-50% according to studies. Counting lets you know exactly what you're eating and guarantees a consistent calorie deficit.

How to start counting

Start by tracking everything you eat for 1 week without changing your habits. This gives you a baseline of your current intake. Then, calculate your TDEE and set a goal 500-700 kcal below.

Calorie counting pitfalls

Common mistakes include: forgetting cooking oils, underestimating portions, not counting drinks and snacks, systematically rounding down. Precision is key: use a food scale at first.

Making counting sustainable

To stick with it long-term, tracking must be simple and fast. That's why Voical lets you track in 15 seconds per meal. Long and tedious methods lead to quitting. Simplicity is the key to consistency.

Important

Never go below 1200 kcal/day (women) or 1500 kcal/day (men) without medical supervision. Too aggressive a deficit can be dangerous for your health and counterproductive for weight loss.

Complete Guide to Calorie Counting

Counting calories is the cornerstone of any successful weight loss. This guide teaches you how to do it effectively without it becoming a chore.

Why Counting Works

The Estimation Problem

Studies show we’re very bad at estimating calories:

  • Average underestimation: 20-50%
  • “Eyeball” portions are rarely accurate
  • Hidden calories (oils, sauces) are often forgotten

The Solution: Precise Tracking

With rigorous tracking:

  • You know exactly what you’re eating
  • Deficit is guaranteed and measurable
  • Progress is predictable

How to Get Started

Step 1: Calculate Your Needs

  1. Calculate your Basal Metabolic Rate (Mifflin-St Jeor formula)
  2. Multiply by your activity level to get TDEE
  3. Subtract 500-700 kcal for your goal

Step 2: Get Equipped

  • A kitchen scale (1g precision)
  • A tracking app (Voical)
  • Containers with known portions

Step 3: Track Everything for 1 Week

Before reducing, observe your current habits. You’ll probably be surprised by certain foods.

What to Track

Never Forget:

CategoryExamplesHidden Calories
Cooking oilsOlive, canola90 kcal/tablespoon
SaucesKetchup, mayo50-100 kcal/tablespoon
DrinksJuice, sodas, alcohol100-200 kcal/glass
SnacksNuts, dried fruits150-200 kcal/handful
DressingsSalad oil100 kcal/tablespoon

Techniques to Simplify

  1. Meal prep: Prepared meals have known calories
  2. Recurring meals: Often eat the same bases
  3. Scan barcodes: Fast and accurate
  4. Voical: Describe your meal verbally, 15 seconds

Common Mistakes

  • Not counting weekends: “It doesn’t count” = false
  • Rounding down: “About 100 kcal” = often more
  • Forgetting liquid calories: They count just as much
  • Getting discouraged by slip-ups: One day doesn’t change everything

Why Voical Can Help You

Traditional counting takes 5-10 minutes per meal. With Voical, 15 seconds is enough: describe your meal out loud and the AI does the rest. This simplicity makes the difference between giving up and sticking with it long-term.
