Energy balance

Increased body fat is associated with elevated resting metabolic rate and protein turnover, even after accounting for lean body mass (total body potassium).

Having more body fat does not mean your metabolism is 'slow' relative to your lean mass. In fact, higher fat mass is associated with higher metabolic rate and protein turnover, even when you account for your lean tissue.

GoodSupportsHIGH confidence
Metabolic rate and protein turnover were highest in the subjects with the greatest amount of body fat, even after accounting for differences in whole body potassium.

Why this rating

Robust correlation (r=0.42-0.46) in a controlled setting, though observational in nature regarding fat mass.
