For example, you can get a McDonald’s Double Cheeseburger without the bun for 4 grams of carbs. The Chick-Fil-A Grilled Chicken Nuggets dipped in 2 servings of ranch and avocado dressing is around 2 grams of carbs [1,2].
2. Choose a Low-Carb Burrito Bowl
You’d be surprised by the high-carb content of a single burrito wrap. Some bring a whopping 50 grams, which definitely isn’t suitable for keto dieters. Skip the burrito wraps and shells and build a delicious burrito bowl. Start with leafy greens or a low-carb base, add your preference of fat and protein choices, and avoid high-carb toppings like beans, sugary dressings, corn, and tortilla chips.
Most fast-food restaurants have plenty of high-fat, low-carb options like sautéed veggies, sour cream, salsa, sliced avocado, onions, cheese, and fresh herbs. For example, the Chipotle Steak Burrito Bowl with lettuce, sour cream, salsa, and cheese (no rice or beans) gives you around 6 grams of carbs, 23 grams of fat, and 29 grams of protein .
3. Eggy Breakfasts!
Most fast-food places offer eggs — a perfect keto-friendly food. Eggs are high in protein and fat, but they’re especially low in carbs. One egg has less than 1 gram of carbs .
You could order plain eggs with a side of cheese and sausage and ditch the carb-heavy hash browns, potatoes, or pancakes. The McDonald’s Big Breakfast without the hash browns or biscuit only has 2 grams of carbs. Why not try a salad on the side?
If you have time to stop in a deli, grab an omelet with greens and cheese and an unsweetened coffee.
4. Low-Carb Salads
Even some salads from fast food establishments can be high in carbs, primarily due to the dressings, dried fruit, and marinades that quickly bring up the carb count. A Wendy’s full-sized Apple Pecan Chicken Salad has 40 grams of sugar and 52 grams of carbohydrates! 
Thankfully, you still have lots of keto-friendly salads available to you, such as the Chipotle Salad Bowl with steak, cheese, romaine, salsa, and sour cream with around 7 grams of carbs.
McDonald’s Bacon Ranch Grilled Chicken Salad with guacamole has 10 grams of carbs.
