It's true, a lack of sleep may sabotage your diet! Studies have shown that persons who don't get enough sleep are not only crabby, but they are also hungry! Dr. Oz, who so many of you follow religiously, warns that "People who don't sleep crave carbs." A University of Chicago study showed that persons who only slept 5 1/2 hours a night snacked more the next day. Most people need 7 hours of sleep for their bodies to be rested.
Researchers at McLean Hospital in MA did a study by hooking people up to functional-MRI machines and showed them pictures of high-calorie foods such as chocolate cake. Those who had earlier reported daytime sleepiness had lower activity in the "willpower-regulating" areas of the brain than when they viewed salads, etc. The lead author of the study, William D.S. Killgore, Ph.D. stated, "If your zzz's get cut short, a siesta may help strengthen your resolve."
