Understand calorie and macro estimates, review food portions and build an editable meal log with CalShutter.
No universal diet target or accuracy guarantee. Protein, carbohydrate and fat are macronutrients.
Food labels and recipes can help describe their amounts, but food quality and personal health needs also matter.
A macro split alone does not establish an appropriate diet or guarantee a body-composition result.
Use an individual plan agreed with a qualified professional if you need dietary targets.
Read available food labels and portion information.

Review steps before using a dietary target
- Clarify why you are recording food.
- Use an individual plan agreed with a qualified professional if you need dietary targets.
- Read available food labels and portion information.
- Review estimates before saving.
This page does not prescribe a universal protein target, fat percentage or calorie deficit.
Do you even need to count macros?
You do not need to turn every meal into a macro calculation.
Decide whether a general food log meets your goal.
Medical conditions, pregnancy and other individual circumstances require guidance beyond this consumer-app tutorial.
Tracking macros without the spreadsheet
In CalShutter, take a food photo or use voice/manual entry. Review the estimated calories and macros and correct the entry.
Estimates cannot reveal all ingredients; no time-per-meal or precision threshold is promised.
