Why Standard Diet Apps Fail You
Due to reduced cellular T3 availability, your mitochondrial oxygen consumption is blunted, reducing your maintenance calories below standard population equations. Extreme low-calorie dieting further raises Reverse T3; target gentle 250-calorie deficits paired with resistance exercise.
