Bit of a summary from 4 day break in Cornwall - had some issues at cafes and restaurants due to limited low carb & veggie choice (OK there wasn't any choice! ). Had tried to plan ahead and check out menus online only to find that the hotel we stayed in said it was "for guidance" the only thing they didn't have was the veggie low carb salad!
Majority of the items on the menu were very high carb, burgers, chips, pasties/pies, "salad" with loads of grains in it etc but it was still possible to work around it - most places had a side salad on the menu.
I had a week of eating salad and cheese, but did enjoy lots of clotted cream with a few fresh berries
B: nuts (taken with us) - scrambled eggs were avoided as from a pack mix with thickeners and yogurt was low fat and over 15g of sugar!!!!
L: salad leaves and cheese, olives, seeds from cafe/restaurant if available or from supermarket if not
D: see lunch - followed by a pot of clotted cream and few berries (yep despite having a whole pot of clotted cream and loads of cheese every day I lost 4lb
)
