Lose Weight While You Sleep!


Latest study confirms 7-8 hours/ night is the magic number.

There’s new evidence that too little sleep leads to weight gain. Watch the play of the hormones – (from “Lack of Sleep Can Pack on the Pounds,” by Alan Mozes, Health Day) Report from J. Catesby Ware, chief of the division of sleep medicine at Eastern Virginia Medical School, and director of the Sleep Disorder Center at Sentara Norfolk General Hospital in Norfolk, Va.:“There are a number of research studies that all support the thesis that too little sleep leads to weight gain,” Ware said..” When people don’t get enough sleep, levels of the hormone leptin DECREASE.  This hormone makes us feel satiated (not hungry).Conversely, levels of the hormone ghrelin, which sparks hunger, INCREASE — prompting cravings for candy, cookies and cake.

Dr. Phyllis Zee, a professor of neurology at the Northwestern University Feinberg School of Medicine, said that while researchers continue to be stymied by the exact nature of the sleep-weight connection, the relationship is undeniable. Too little sleep, and the hormonal and metabolic profiles begin to resemble people who are pre-diabetic, while bringing about autonomic changes that can be related to the development of cardiovascular disease.

How are we sleeping?

     * 70+%  of adults over the age of 18 get less than eight hours of sleep a night on weekdays

     * 40%  get less than seven hours.

     * Adults between the ages of 18 and 54 sleep just 6.7 hours a night during the week, and seven hours a night on weekends.

     * Adults aged 55 to 84 — 13 percent sleep less than six hours a night during the week, while 11 percent have a similar sleep pattern on weekends.

“Between seven and eight hours seems to be a fairly magical number for sleep duration,” said Zee.

“People who report, on average, getting between seven and eight hours of sleep are the ones who appear to have the lowest risk” of weight gain. Ware agreed: “By sleeping more, you gain on all fronts. If you are obese and are trying to lose weight, it’s almost a no-brainer.
