What period of fasting is required to avoid error in the RMR measures when meals >900 kcals are ingested?

Conclusion

If a very large meal (>900 kcal) is consumed within 5-hours of a RMR measurement, then a longer time (at least 6 hours) is recommended to reduce diet-induced thermogenesis impact on RMR to clinically insignificant levels (<100 kcals/day) in individuals.
