Tips for Eating Keto Fast Food

  • Plan Ahead: Before heading to a fast-food restaurant, check their menu online to identify keto-friendly options. Planning can prevent impulsive decisions that may not align with your diet.
  • Skip the Bun or Wrap: Most fast food chains offer burgers or sandwiches. Opt to remove or replace these with lettuce wraps or enjoy the insides on their own.
  • Be Cautious with Sides: Skip high-carb sides like fries and opt for lower-carb alternatives like side salads or non-starchy vegetables.
  • Watch Out for Hidden Carbs: Some seemingly harmless toppings, sauces, or condiments may contain hidden sugars or carbs. Be cautious with ketchup, BBQ sauce, and other sweet dressings.
  • Practice Portion Control: Even though certain items may be keto-friendly, it’s essential to be mindful of portion sizes to stay within your daily keto macros.
  • Get Unsweetened Beverages: Skip the milkshakes and order unsweetened coffee or tea instead.
