How does Platify work out my starting calorie target?

Your starting calorie target comes from the Mifflin-St Jeor equation, a well-established formula that estimates how much energy your body burns at rest from your sex, age, weight and height. Platify then factors in your activity level and your goal, whether that's losing, building or maintaining, to land on a daily number. It's a starting point, not a fixed number: you can recalculate or edit it any time on your Targets screen.

Where does the number come from?

The Mifflin-St Jeor equation is a research-backed formula for estimating resting energy needs from your sex, age, weight and height. It's the same equation used widely across sports nutrition and coaching, not something Platify invented.

Why does my goal change the number?

Once your resting energy is estimated, Platify multiplies it by your activity level to get a maintenance number, then nudges it for your goal. Losing weight applies a modest calorie reduction. Building applies a modest calorie increase. Maintaining leaves the maintenance number as is.

Is this the same as "evidence-based nutrition"?

The equation itself is research-backed. The goal adjustment and macro split on top of it are a sensible starting point that sit within Australian dietary guideline ranges, not a personalised prescription. That's why we call it a starting point, not a promise.

What if I don't like the number?

Change it. Free members can edit their calorie and macro targets directly, or tap Recalculate from inputs to run the formula again with updated body details. Premium members get the same editing tools, plus a nutrition coach that helps adjust targets over time.
