Macro partitioning
Lactate inhibits lipolysis in adipose tissue via HCAR-1 receptor binding and inhibits mitochondrial fatty acid oxidation via malonyl-CoA, thereby controlling energy substrate partitioning.
During high-intensity exercise, your body temporarily shifts away from burning fat to use lactate as fuel. This is a normal metabolic switch, not a failure of fat loss mechanisms.
GoodSupportsHIGH confidence
By inhibiting lipolysis in adipose via HCAR-1, and muscle mitochondrial fatty acid uptake via malonyl-CoA and CPT1, lactate controls energy substrate partitioning.
Why this rating
Supported by studies on dogs, humans, and molecular mechanisms.
