A calculator is the start—not the verdict.
Calorie equations are useful for choosing an initial target. They cannot directly measure your personal maintenance calories, and activity estimates are broad by design. That is why our calculator labels its output as a starting estimate.
Your log creates the useful evidence.
A target only becomes meaningful when you compare it with what you actually ate and how your body weight responded. Consistent food logs and weigh-ins make that comparison easier to interpret.
The plan should be allowed to adapt.
BulkBro is built around a completed seven-day loop: log, weigh in, evaluate, and adjust when the response is different from the intended pace. The guides explain the reasoning; the app helps you repeat it.
