Sustainability of diet based on moderate calorie restriction among obese patients with metabolic-associated fatty liver disease

Background and Aim: The long-term sustainability of weight loss continues to be a subject of investigation. This study was designed to examine the effects of weight loss and the long-term sustainability of lifestyle modifications among obese patients with metabolic-associated fatty liver disease (MAFLD). Materials and Methods: A total of 40 patients who were prescribed a hypocaloric diet (~500 calories reduction for each patient), and who were followed up for 12 weeks in 4 face-to-face interviews were enrolled in the study. The patients were contacted at the 36th month, and their current weight was recorded. Results: The mean weight at baseline of 87±13 kg decreased to 79±11 kg after 12 weeks of intervention (p<0.001). The mean weight at the 36th month did not significantly differ from that measured at the baseline (p=0.563). The mean controlled attenuation parameter decreased from 320±13 dB/m to 273±37 dB/m (p<0.001), while the median liver stiffness measurement decreased from 8.7 kPa (3.6–45.7 kPa) to 5.7 kPa (2.2–29.9 kPa) (p<0.001). Conclusion: Strict follow-up through nutritional consultation can help achieve weight loss in obese patients with MAFLD. However, for long-term results, the collaboration of nutritionists and gastroenterologists is essential to prevent weight regain.
