4.1. Limitations
This study has some limitations. First, the small sample size impacts the generalizability of the findings. In addition, the lack of blinding, despite the study’s randomized controlled design, increased the risk of selection bias. Moreover, the use of self-reported questionnaires might have further impacted the reliability of results. Lastly, the lack of an objective scale with which to measure adherence to dietary advice might have had a negative impact on the final results.
