FatMax Zone
FatMax zone is the intensity where absolute fat burning peaks—usually moderate aerobic effort—useful for base building and metabolic flexibility, not a fat-loss shortcut alone.
FatMax zone is the exercise intensity where fat oxidation per minute peaks—often near comfortable aerobic effort, not maximum fat percentage of calories (which is higher at rest). Lab metabolic carts locate it; field proxies use nasal breathing zone-2 feel or heart-rate drift tests.
It supports endurance base and metabolic flexibility but does not replace calorie balance for fat loss.
Common questions
-
Is FatMax the same as zone 2?
They overlap for many people but are not identical—FatMax is lab-defined peak fat oxidation; zone 2 is a training band. Use talk-test and HR drift if you lack lab data.
-
Does training in FatMax burn the most body fat?
Total fat loss still depends on weekly energy deficit and protein—FatMax sessions improve aerobic efficiency and substrate use, not magic spot reduction.
