Sleep benefits metabolism
A lack of sleep in only one night would change the metabolic rate and lead to weight gain. In other words, sleep deficiencies would slow down your metabolism partly because the body will burn calories when it is repairing itself during sleep. So, the question here is that: should you work out or have an extra hour of sleeping? The answer is to do both. The best option is to sleep in and do more exercise during the day. This will optimize your metabolic rate and speed up the process of burning calories. [8]
