Your fat-burning machine doesn’t have to switch off when you’re eating out — you just have to know how to make good choices.

In other words, don’t be shy about asking for substitutions or having food prepared with sauce on the side. Here are some suggestions for what to order at restaurants and fast-food joints.

Chinese: whole steamed fish; chicken with broccoli (sauce on side); Szechuan prawns

Mexican: fajita salad with chicken, shrimp or beef (ask for salad on a plate — skip that deep-fried tortilla shell); beanless chili; grilled seafood, beef or chicken with salsa on the side

Japanese: sashimi; grilled meat or fish with teriyaki sauce on the side; negimaki

Italian: steamed clams or mussels; calamari salad; antipasto (cured meats, cheese, mushrooms, olives, artichoke hearts, pepperoncini)

Seafood: fresh lobster; crab salad; steamed clams; any broiled fish

Barbecue: pork, beef or chicken with barbecue sauce on the side

Greek: Greek salad with feta cheese and olives; chicken or lamb souvlaki; grilled chicken or shrimp shish kebab with vegetables

Chipotle:

burrito bowl (preferably without guacamole, sour cream or cheese, but, if you must, just have a small amount on the side)

KFC: grilled-chicken-breast dinner

Wendy’s: Asian cashew chicken salad with light, spicy Asian chili vinaigrette

McDonald’s: Artisan grilled chicken sandwich

Subway: six-inch turkey-breast sub on toasted nine-grain wheat bread with lettuce, tomatoes, green peppers and spicy mustard

Pret A Manger: Wild salmon salad with honey-roasted sunflower kernels and light Italian dressing

Starbucks: Roasted-vegetable panini; wheat wrap with cage-free egg whites, spinach, feta cheese and tomatoes
