A University of California, Berkeley Wellness report indicates that a high-protein weight-loss diet may help people sleep better.
For four months, 44 overweight or obese people were put on either a normal-protein or high-protein calorie-restricted diet and were asked to complete a standard sleep-quality questionnaire once a month.
At three-month and four-month follow-up, the high-protein dieters reported improved sleep, compared to the lower-protein group. The normal-protein diet provided the daily recommended dietary allowance (RDA) for protein, which is a modest 0.8 grams per kilogram of body weight (that works out to 65 grams for a 180-pound person).
