How a Low Carb Diet Works

When it comes to starting a low carb diet like Atkins, it's all about eating right, not less.

A typical diet may reduce calories, but is still high in carbohydrates (and sugar) which may cause continuous cycles of sugar highs and lows, making you more fatigued and hungry—without any weight loss.

Alternatively, a low carb diet focuses on limiting 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.
