Fast Foods To Avoid When On A Low-Carb Diet

If you’re on a low-carb diet, you should AVOID certain foods when eating out. Let’s take a closer look:

  • Almost anything deep fried, for example – French fries, onion rings, mozzarella sticks – is high in carbs.
  • The same goes for doughnuts, pastries, and other baked goods made from refined flour and sugar.
  • Pizza places are also generally a no-go; while some offer gluten-free crusts or cauliflower crusts, they’re usually loaded with toppings that add up to too much carbohydrate content.
  • Fried chicken (even if it’s not breaded) is also a no-go because of the amount of oil and fat used to cook it.
  • Soft drinks and other beverages labeled “diet” may be okay if you read the ingredients list first and make sure they don’t contain hidden carbs.
