Do not trade sleep for exercise. You need both to be healthy.
“In a 2004 study, men limited to only four hours of sleep a night reported increased appetite and showed hormonal changes consistent with increased hunger…sleep loss can wreak havoc with a person’s endocrine system, the hormones that control appetite and metabolism.”

In our study it reduced fat loss by 55 percent.
