Your protein target is probably about half of what you think.

Enter your weight, say how you train, and see the number split across four meals.

Two thirds of 3,000 adults surveyed in July 2026 put their daily protein target under 50 grams. For most women who train, the real number is closer to double that. The gap is arithmetic, not discipline.

Three things decide your number: your bodyweight, how hard you train, and whether you actually spread the protein out. The calculator handles all three.

Why breakfast is where this usually breaks

The ISSN position stand recommends spreading protein in doses of about 0.25 g per kg, every three to four hours, rather than loading most of it at dinner. Almost nobody does this. Breakfast comes in at 8 or 10 grams, lunch is a salad, and then dinner tries to carry 60.

Moving protein to breakfast is the single change that fixes the daily total for most people, and it does not cost anything.

The three numbers, and where they come from

Sedentary1.2 to 1.4 g/kg2025-2030 Dietary Guidelines
Mostly cardio1.4 to 1.6 g/kgISSN position stand
Lifting hard1.6 to 2.0 g/kgMorton meta-analysis, ISSN

Morton's review of 49 trials and 1,863 people found gains from resistance training kept improving up to about 1.6 g/kg/day, with little added benefit above that. The ISSN range runs to 2.0 g/kg for exercising individuals. If you are pregnant, breastfeeding, or living with kidney disease, these ranges do not apply to you without medical supervision.
