Calorie Counting for Beginners: Start in 5 Minutes, No Food Scale
By Jess, Certified Personal Trainer
how to count calories
Calorie counting takes three steps: find your TDEE, the energy your body uses daily; set intake 300 to 500 kcal below it; and log every meal. The easiest method in 2026 is photographing your food and letting the Be Fit With Jess AI do the math, no scale and no memorized food values.
Step 1: Know your TDEE
TDEE is what your body truly burns daily from base metabolism plus activity. Most women land around 1,600 to 2,000 kcal depending on weight and movement; the app calculates yours automatically at signup.
Step 2: Set a moderate deficit
Eating 300 to 500 kcal under TDEE loses about half a kilogram weekly without misery. Cutting harder brings brutal hunger, early collapse, and yoyo risk. Slower but arriving is the rule of this game.
Step 3: Log everything, especially bad days
Log every meal including drinks and snacks. Heavy days carry the most valuable data, so never stop logging out of guilt, and judge weekly averages rather than single days.
The classic beginner mistakes
• Forgetting drink calories: one Thai tea equals half a plate of rice
• Underestimating portions: studies find people misjudge by 30 to 40 percent, and photos close that gap
• Quitting after one bad day: one meal never caused weight gain; a stopped system did
FAQ
Do I count forever?
No. Most people count strictly for 2 to 3 months until intuition forms, then only when goals change.
Calories or exercise: which matters more?
For weight loss, food is 70 to 80 percent of the result, but training preserves muscle and reshapes your body, which is why the Be Fit With Jess app holds both.
