Compare Two Diet Approaches for Someone Who Travels for Work Weekly

Most diet advice assumes a stocked kitchen and a predictable evening, neither of which a frequent traveller has. This compares your two options on how they hold up with limited menu control, how gracefully each copes when the planned meal is not available, and what prep they actually demand before a trip.

2. Which one degrades more gracefully when a planned meal is not available
3. The practical prep or planning each one demands before a trip
4. Give a one line verdict for frequent travellers specifically, not a general health comparison
