Calorie Deficit

A Calorie Deficit occurs when intake is lower than daily expenditure, producing weight loss over time.

Adaptive Calorie Goals

Adaptive Calorie Goals adjust daily intake targets from a rolling evidence loop

Refeed Day

A refeed day temporarily raises calories (often via carbs) during fat loss to support training and adherence.
