Reviewer's report:  
 
This an intriguing study evaluating two different nutritional dietetic approach to suggest to 
NAFLD affected patients.  
The study was designed in a correct way and results seem supporting the initial aim of the study 
trying to confirm the superiority od the Alternate Diet Fastinf (ADF) when compared to Time 
Restriction Diet (TRD). A co ntrol no dieting group of patients was appropriately followed and 
compared with both dieting groups.  
 
A part from the limitations declared by the authors themselves I have two more questions: - 
 
- can the authors present data as per individual changes rathe r than mean and SD ?  
 
- how they explain a loss of weight either at 4 and 12 weeks also in non -dieting people (control 
group) ?  
 
minor comments:  
 
- it might be stated in the detail, a part from the percentage of diet constituents, the amount of 
calories an d the type of diet of the fasting day.
