Right from the very beginning, Atkins has had science at its heart. In fact, in the last 40 years there’s been over 100 peer-reviewed studies that show a low carb diet is a safe, natural and effective way to lose weight and maintain a healthy lifestyle.

A fat burning machine

To understand how and why low carb diets work, first we need to understand the relationship between the food we eat and the way our bodies get their energy. 

Your body uses both carbohydrates and fat as fuel. If carbs are available, your body will use this energy source first. If these carbs aren’t used up, they’re stored as fat. The typical western diet is carb-heavy, which means most of us don’t use up the fat that our body stores away, which is one of the reason why we are getting fatter. 

Kickstarting ketosis

On a low carb diet, you reduce the amount of refined and sugary carbs that you eat. Without as many carbs to use as energy, your body naturally starts burning fat instead – and that includes the fat your body has stored up. This is called ketosis. 

Weight loss and other benefits

Losing weight is just one of the many benefits that a low carb lifestyle could bring, here are a few of the others: 

  • No spikes and dips in blood sugar
  • Sugar cravings disappear
  • You no longer feel as hungry
  • Energy levels increase (after the first week or two)
  • Metabolic conditions such as heart disease, hypertension, diabetes and inflammation can improve
  • Blood triglyceride (fat) levels and cholesterol are reduced


In addition to this, many people who follow Atkins experience tell us they feel happier, there are fewer occurrences of depression, and the condition of their skin, hair and nails improves. 

Ever evolving

With obesity being one of the world’s most pressing health issues, new research into low carb, high protein diets is taking place all the time. And as our understanding continues to evolves, so does Atkins.

It’s the job of our Science Advisory Team, a group of nutritional experts, to evaluate and improve our plan in light of any new developments. That way we can make sure our approach reflects the very latest advances in low carb nutrition.
