Those who claim they "get by" on very little sleep are likely fooling themselves, but their bodies won't fool them for too long. Eventually, that lack of sleep will show up somewhere in the way they look or feel (or both).

The quantity of sleep you get could be affecting not just your weight, but your potential to become obese. If that is not a wake-up call, I do not know what is.

Restricting the time that you have in bed can be causing you to suffer significant sleep deprivation. And we all know that sleep deprivation has some significant effects on weight loss.

Many sleep problems can be attributed to an internal clock that has become out of sync. Sometimes your body's clock just doesn't quite match up with society's 24-hour clock.
