Early time-restricted eating effective for losing weight, mood improvement
Early time-restricted eating was found to be more effective for losing weight and improving diastolic blood pressure and mood compared with eating over a period of 12 or more hours in a new randomized clinical trial.
In this 14-week, parallel-arm trial, 90 participants receiving weight-loss treatment (energy restriction [ER]) were randomized to eTRE+ER (8-hour eating window from 7:00 to 15:00) or control eating (CON) plus ER (≥12-hour window). The eTRE+ER group adhered to the treatment plan 6 days per week.
The eTRE+ER intervention was found to be more effective for losing weight and the equivalent of reducing calorie intake by an additional 214 kcal/d. However, body fat or the ratio of fat loss to weight loss was not affected. Diastolic blood pressure and mood disturbances were also improved with eTRE+ER intervention.
In a secondary analysis including 59 participants, eTRE+ER was found to be more effective for losing body fat and trunk fat than CON+ER.
