How a Low Carb Diet Works

A low carb diet focuses on limited carbohydrates to help the body burn fat instead of sugar for fuel. This contributes to higher, consistent energy levels throughout the day, allowing you to reach weight loss and weight maintenance goals.

What is a net carb?

In packaged or low carb foods and drinks:
Net Carbs = Total Carbohydrates – Fiber – Sugar Alcohols – Allulose (if applicable)

In whole foods and drinks:
Net Carbs = Total Carbs – Fiber

Net carbs reflect the grams of carbohydrate that significantly impact your blood sugar level. When participating in an Atkins diet plan, you’ll need to calculate net carbs.
