I am just back from a 4 day break in Rome and in high ketosis. We did a lot of walking around to see the sights and Rome is truly a wonderful place but is over-run with what seemed like Afghan and African hawkers with a few Gypsy type women beggars and one or two Italian Winos.
The Italians themselves are very friendly, gracious and kind. Motorists do beep-the-horn a bit in traffic but not as frantically as I’d been led to believe. Pedestrians for the most part seem to claim automatic right of way at un-signalised pedestrian crossings.
I tended to stay keto but did share a Pizza one night and had beer at another meal. In the evenings I generally drank 1 or 2 glasses of wine. I did have to increase my fibre intake by eating the Pizza and 2 apples and 2 kiwis on my second last day basically because I was taking too long in the bathroom. My digestive system responded well without any emergencies but I can’t say how it would have reacted to loads of pasta dishes.
If you do go for Pasta etc… you will get good value and enjoy the food. As a family of 5 consisting of 4 adults and one teenager, I was the only one that had any reservations about the food especially one “mixed roast” which turned out to be 2 loin lamb chops and some sort of minced meat blob with a side of spinach. The restaurants in effect didn’t really do roasts at all; I did have roast beef, without gravy, in an “Irish pub” but it was basically too lean and only available at the weekends. At one of the more modern Burger joints at Termini railway station bun-less burgers were one the menu and mine was just perfectly char-grilled along with the veggies.
Enjoy your trip.
