The Effect of Eucaloric High-Protein Fiber Diet in Healthy Adults: A Repeated Single-Arm Clinical Trial

Several studies have shown that high protein diet can reduce body fat, increase muscle mass, and improve some metabolic parameters of subjects. Also, several studies have shown that high intake of fiber could reduce body weight and improve cardiometabolic parameters. Therefore, combining high-protein diet and high-fiber diet should have a positive synergistic effect on several of anthropometric and metabolic parameters. The aims of this study is to investigate the effect of eucaloric high protein and fiber diet on healthy subjects. Thirteen healthy subjects, age 29,85 ± 4,06 years old, with body mass index (BMI) 29,55 ± 4,12 kg/m2 were prescribed eucaloric high protein diet for two weeks, followed by washing period for two week. Then, they were prescribed with eucaloric high protein and high fiber diet for two more weeks. Twenty grams of dietary fiber were in the form of isomaltooligosaccharides (IMO) based creamer formulae. Their body composition, waist circumference, fasting blood glucose, blood uric acid and total cholesterol concentration were measured after every dietary intervention.
