Steak houses with all-you-can-eat-salad bars are often excellent values. Other restaurants can have salads that are too small and overpriced.

[McDougall avoids added oil, but allows small amounts of refined grains and sugar]

Most meat, cheese, and sugar at restaurants are easy to detect and avoid. Added oil is much sneakier.

Most cooked vegan foods at restaurants have added oil. 20% to 30% of calories from added oil is common. In South Asian cuisine, many of the preparations involve soaking the spice in oil for a time before cooking.

Traveling salespeople and truck drivers have less opportunity to eat WFPB. Truck stops and small-town restaurants may not have WFPB on the menu.

Pack or buy foods listed on Easy WFPB.

Just eat WFPB when you can. A 50% WFPB diet has 50% of the health benefits. Which is still far healthier than the standard American diet.
