"Juicing in general reduces the fiber content and therefore decreases the feeling of fullness gained by eating fresh, crisp fruits and vegetables," says Ashley Barrient, MEd, LPC, RD, LDN, dietitian, Loyola Center for Metabolic Surgery and Bariatric Care."
Patients who consume whole fruit and vegetables report greater fullness and overall satisfaction with their diet." Barrient specializes in working with weight-loss patients.
"The concentrated sugar and caloric content of juice can result in "Dumping Syndrome" which includes diarrhea, rapid pulse, cold sweats, nausea and uncomfortable abdominal fullness," says Barrient.
The sugar and calorie content of juice is much greater than the sugar content of whole fruit and vegetables, and it takes several pieces of produce to make an average-sized portion, she reports.
The concentrated sugar and caloric content of juicing also discourages weight loss post surgery and increases the risk for weight regain in the future.
"Aim for a diet rich in lean protein and dairy, fruits, and vegetables and ensure adeqquate water intake," says Barrient. She also emphasizes the importance of supplementing diet with required vitamins and minerals for lifetime following weight loss surgery.
"The most successful diets are those that can be sustained," says Barrient. "For most people, juicing is a trend, and trends do not last."
