Why is a Big Mac not keto

A traditional Big Mac from a fast-food restaurant is not considered keto-friendly for several reasons:

The most significant factor is the high-carbohydrate content of the bun. The standard sesame seed bun used in a Big Mac is rich in carbohydrates. Also  the special sauce in a Big Mac typically contains added sugars and other ingredients that may contribute to carb count, making it less suitable for a keto diet.

Ketchup, another common component of a Big Mac, contains sugar, which adds to the overall carbohydrate content. In a ketogenic diet, it’s essential to minimize the intake of added sugars. While onions are present in a Big Mac and can be part of a keto diet in moderation, they do contribute to the overall carb count, and some keto followers may choose to limit their onion intake.

The processed cheese used in fast-food burgers might contain additives and fillers that could have hidden carbohydrates.

In contrast, a Keto Big Mac Casserole recipe aims to recreate the flavors of a Big Mac while using keto-friendly substitutes for the high-carb components. This often involves replacing the traditional bun with low-carb alternatives, using sugar-free or keto-friendly sauces, and ensuring that all ingredients align with the principles of a ketogenic diet, which emphasizes low-carb, moderate-protein, and high-fat intake.
