Energy balance

The standard 1 MET value (3.5 mL O2/kg/min) significantly overestimates resting energy expenditure and total energy expenditure in overweight and obese individuals.

If you are overweight or obese, do not use the standard 1 MET value (3.5 mL O2/kg/min) to estimate your energy expenditure. It will significantly overestimate your resting energy expenditure (by ~20%) and total energy expenditure. Use BMI-specific correction factors or measured resting metabolic rate for more accurate calculations.

GoodRefutesHIGH confidence
In a heterogeneous sample of 769 weight-stable and healthy adults (18–74 years of age, 35–186 kg), the 1 MET value of 3.5 mL/kg × min overestimated the actual resting VO2 value by an average of 35% and the 1 MET of 1 kcal/kg × h overestimated REE by 20% (18). Very recently, Wilms et al. (62) confirmed that the commonly used 1 MET value largely overestimated EE in overweight to obese individuals and produced BMI-specific MET correction factors.
