Founder ยท Software author

Aaron Bergquist

Aaron created Deficit Compass from a personal calorie-planning spreadsheet and is responsible for the product logic, software implementation, methodology documentation, and correction process.

Role and experience

Aaron translates published calorie-estimation equations and the original planning sheet into browser-based tools. His work on Deficit Compass includes input validation, formula comparisons, goal forecasting, accessibility, privacy controls, and documentation that shows where each estimate can fail.

He is the product owner and software author. He is not a physician or registered dietitian and does not present the calculator as individualized medical or nutrition care.

Editorial standard

Health-adjacent claims are linked to primary research or public-health guidance where possible. Project-specific heuristics are labeled as such, limitations are published, and the site does not claim medical review it has not received.

Review the complete methodology and source list or read the calorie deficit guide.

Corrections

Report formula, source, accessibility, or implementation errors to hello@deficitcompass.com. Corrections that change methodology are documented on the methodology page.
