Now, you might be thinking, "Wait, isn't a beef patty mostly protein?" And, you're right! However, many commercial hamburger patties contain added fillers like breadcrumbs or flour, which can increase the carb content. Some patties can have up to 20% carbohydrates by weight - that's a lot of hidden carbs!
But, don't worry, not all hope is lost for our low-carb friends out there. You can always opt for a bunless burger or try a portobello mushroom cap as a low-carb "bun" substitute. Get creative, people!
