Does the body have a metabolism cycle throughout the day ?

Question

For example, is metabolism higher in the morning than at night, or whatever ?

Answer 1

the metabolic rate is at it's lowest right before awakening then increases during the morning and starts to decline in the evening. body composition plays a large role in the difference between the resting and sleeping metabolic rates. the more muscle mass a person has the less of a decrease there is between the RMR and the SMR.
