01 Daily Target

CALCULATE YOUR MACROS

Estimates daily energy needs with the Mifflin St Jeor equation, then sets protein from body weight and allocates the remaining calories between fat and carbohydrate.

Your details
Goal
Uses a moderate starting adjustment of 15 percent below maintenance for fat loss, 10 percent below maintenance for body recomposition, and 10 percent above maintenance for gain. Fill in Desired weight and Timeframe weeks below to replace this generic estimate with your own timeline. Available on every direction except Maintain, which is a zero rate of change by definition.
Fill this in with Desired weight to calculate the calorie deficit or surplus your own timeline requires, instead of a generic estimate.
Macro settings
Evidence-based range for Maintain: 1.6–2.0 g per kg (bodyweight-based, not a % of calories). Adjust to suit your plan.
20–30% of calories is a reasonable range for most goals; 25% is a solid default.

How it works

USE THE NUMBER.
THEN USE THE FEEDBACK.

The calculator creates a starting target. Your real response over several weeks tells you whether the target is serving the goal.

What the calculator uses

Energy. Resting energy is estimated from age, height, body weight and sex, then multiplied by your selected activity level.

Protein. Set in grams per kilogram using either current or desired body weight.

Fat. Set as a percentage of daily calories.

Carbohydrate. Receives the calories remaining after protein and fat are allocated.

Member practice
Choose a target. Follow it consistently. Review body weight, energy, training performance and recovery. Make small changes from evidence rather than from one unusual day.
This tool is for general adult education and planning. It is not medical nutrition therapy and is not a substitute for individual advice from a qualified health professional.
