To reach this conclusion, researchers from the Pennington Biomedical Research Centre in Louisiana analysed the diets of 218 healthy adults who were followed for two years. They were devided into two groups. One group was randomly assigned to cut their calorie intake by 25 percent.
The other group went on with the regular diet. One of the researchers Corby Martin found that the calorie-restriction group reported improved mood and sex drive, www.sciencealert.com reported. The calorie-restriction group also lost weight and enjoyed better sleep.
Calorie restriction among primarily overweight and obese persons has been found to improve sleep and sexual function. “The results of the present study indicate that two years of calorie restriction is unlikely to negatively affect these factors in healthy adults,” the authors wrote in the journal JAMA Internal Medicine.
