As funny as it sounds, sleep deprivation may make you fat — and not just because you're susceptible to cases of the late-night munchies (although there's that too). There's tons of research that demonstrates getting less than the desired amount — about 7 hours — of sleep per night can slow down your metabolism. Plus, when you're awake for longer, you're naturally more likely to nosh. So don't skimp on your ZZZs, and you'll be rewarded with an extra edge when it comes to shedding pounds quickly.
“Before you begin to change your diet, spend a week recording everything you eat—and I mean everything. Before I made any changes to my diet, I journaled everything I ate each day for a week, including little things like gum or breath mints. If you have a piece of candy from your coworker’s desk, snag a few spoonfuls of your boyfriend’s ice cream, or finish the few bits of grilled cheese your kid left on her plate, write it down! It all adds up, and you just don’t realize how much you’re eating until you actually see it all on paper in front of you. I, for one, was stunned.” — Maria Menounos, author of The Everygirl’s Guide to Diet and Fitness, on how she lost 40 pounds
Weight can affect a person's self-esteem. Excess weight is highly visible and evokes some powerful reactions, however unfairly, from other people and from the people who carry the excess weight. The amount of weight loss needed to improve your health may be much less than you wish to lose, when you consider how you evaluate your weight. Research has shown that your health can be greatly improved by a loss of 5–10 percent of your starting weight. That doesn't mean you have to stop there, but it does mean that an initial goal of losing 5–10 percent of your starting weight is both realistic and valuable.
