Daily calorie calculator

Enter your sex, age, height, weight, and activity level to estimate resting rate, maintenance calories, and a goal-adjusted daily target. This is education only, not a personalized medical nutrition prescription.

Tool rhythm

Use the tool, then carry forwardthe context that matters.

Each page turns a narrow question into clearer prep: what you entered, what is still missing, and what would be worth discussing with a licensed clinician.

In practice

  1. Start with the numbers, notes, or checklist items you already have.

  2. Treat the result as education and visit prep, not a medical decision.

  3. Use the handoff when your own records can add useful context.

Work the question here, then decide what to carry forward.

Each public tool keeps the input, result, source basis, and safety boundary in one place. When your own records matter, sign in and bring the context into Ojava Coach.

Units

2155 kcal/day targetOjava estimated a 1390 kcal/day resting rate and a 2155 kcal/day maintenance estimate at a moderately active activity level, with a 2155 kcal/day maintenance target.

Resting rate and maintenanceBMR 1390 kcal/day; TDEE 2155 kcal/day at a moderately active activity level.

Questions to bring forward

  • Which of my logged weights should anchor this calorie estimate?
  • How should I adjust this if my activity level changes week to week?
  • What would a registered dietitian want to verify before I use this target?

Estimated calorie needs are general-wellness education from the Mifflin-St Jeor equation and a standard activity multiplier. This is not a personalized medical nutrition prescription, does not diagnose a metabolic condition, and does not replace guidance from a registered dietitian or clinician, especially during pregnancy, breastfeeding, or with a diagnosed medical condition.

What Ojava keeps clear

A calm place to understand the pattern before your next step

Ojava organizes health records, wearable trends, medication context, and visit prep in one view. It explains what signals generally mean and keeps clinician decisions where they belong.

Start with your recordsRead the guides
How the pieces sit togetherThree principles

Your data stays contextual

Daily signals, accepted records, and notes are reviewed together so one lab, symptom, or wearable trend is not treated as an isolated clue.

Education before action

Ojava prepares questions and context. It does not diagnose, prescribe, dose, order labs, or replace licensed care.

One record, many moments

The same structure supports a morning check, a new lab review, and a visit packet when you need it.
