Let me preface this by saying that holiday meals aren't going to make or break your fat loss goals. It's what you do consistently, on a regular basis, that determines your success.
Now, there are several approaches you can choose around holiday times:
1. If you don't have a deadline for your fat loss goals ( a wedding, vacation, and so on), you can use the holiday meal as a 'free meal'. That is, eat whatever you want, enjoy spending time with your loved ones, and hop on the train the next day....
Evidence-based doesn't mean following every study's results blindly.
Evidence-based doesn't mean not taking empirical data into consideration.
Evidence-based means understanding the limitations each study has.
Evidence-based means understanding n=1 doesn't apply to everyone.
Evidence-based means being open-minded and willing to change your stance based on the strength of the studies, that were replicated.
Evidence- based means not 'marry' any position on health and nutrition topics....
