Overweight and obese post-liver transplantation patients will receive a diet to promote weight loss during 6 months. The control group (overweight and obese subjects) will be submitted to the same protocol:
The participants will be interviewed at baseline and after 30, 60, 90 and 180 days from baseline. The following measures will be assessed: body composition (fat body% and free fat body%), anthropometric measures (height, weight, body mass index, waist circumference and abdominal circumference), blood pressure, basal metabolic rate, behavioral symptoms and peripheral biomarkers in the serum. Behavioral symptoms will be assessed using the following self-reported questionnaires: Beck Depression Inventory (depression symptoms), Beck Anxiety Inventory (anxiety symptoms), Medical Outcomes Study 36 - Item Short - Form Health Survey (quality of life) and Perceived Stress Scale (stress).
Enrolled participants will receive a restrictive diet calculated based on individual requirements aiming the loss of around 5%-10% of weight/ 6 months of intervention.
