It works like this. When you are not able to sleep or are just tossing in your bed, your mood is to go to the refrigerator and start binge eating. All of us need atleast 7 to 8 hours of sound sleep every day.

Factors that can prevent you from having a sound sleep and lead to weight gain are:

• While asleep if you are in between a wake and sleep status, then you can get easily awakened. Even a small noise will wake you up easily.
• Dreams during your sleep have more mental activity going on inside you.
• If you have Sleep apnea disorder. Sleep apnea is while sleeping a person stops breathing because his or her airways are obstructed, or blocked.
• Leptin and Grehlin are hormones that help the body control appetite and weight gain and loss. Leptin suppresses appetite, while Grehlin increases appetite and may prevent a person from losing weight. When lack of sleep becomes a chronic problem, levels of Grehlin increases, causing greater appetite, and levels of Leptin decrease. Regardless of diet and exercise, it's possible that some obesity is caused, or made worse, by sleep deprivation.

The longer you are awake, you have more time to eat. It sometimes becomes a vicious cycle. Broken sleep will lead to gain weight and then obesity will lead to broken sleep. So what are the solutions to this.
