Sleeping long enough and well enough may help you shed unwanted pounds, based on one of the first large studies to look at this issue. Once you lose weight, the study suggested that getting enough good sleep may help you keep it off for the long term.
Good Night, Sleep Tight, Feel Light
The research—led by public health professor Cynthia Thomson, PhD, RD, at the University of Arizona—included 245 overweight women who participated in a two-year study of a popular diet plan. “Success” was defined as losing at least 10% of their starting body weight. Women who slept seven or fewer hours per night or who rated their sleep quality as fair to poor were less likely to reach this goal in six months, compared to those who slept longer and better.
The long-term results were similar. Women who slept more than seven hours per night or who rated their sleep quality as very good were more likely to maintain their weight loss for up to 18 months.
