Manuscript IJERPH -1016840 entitled ” Understanding the self-perceived barriers and enablers toward adopting a Mediterranean diet in Australia: an application of the theory of planned behaviour framework” by N. Scannell, is a review focused on to investigate the perceived beliefs, barriers and enablers toward adherence to a Mediterranean Diet in Australian adults. The transferability of the traditional MedDiet to the non-Mediterranean populations is possible, but it requires a multitude of changes in dietary habits. The transferability of the MedDiet may seem challenging, but there are means to overcome this challenge by teaching specific practical recommendations to shift the food pattern to a MedDiet. In my opinion it is an interesting manuscript. The structure is adequate, the bibliographic revision look complete.

The only problem concerns the method of administering the questionnaire. It is preferable to administer questionnaires to the participants in presence, in a face-to-face interview with the participant. The method of administering the "self-administered online" questionnaire is not controlled. The self-administered online questionnaire is not a very reliable method. Lines 236 and 254 (Tables 3 and 4): “*P# refers to study participant”. Authors need to better explain the meaning of the letter P and the number that follows, indicated in tables “(P )”.
