Strategic Transitioning
Phase Transition Calculator
Safely transition between cutting and bulking. Calculate metabolic adaptation recovery times, step-up calorie increments, and maintenance milestones to prevent rapid fat rebound.
Why Bridge?
Jumping straight from a long-term calorie deficit to a surplus is a recipe for rapid fat regain. A 2-3 week maintenance bridge allows BMR to recover, thyroid hormones to normalize, and leptin levels to stabilize.
Rule of Thumb
Keep calories at estimated maintenance for at least 14 days before adding further surplus calories.
