Atkins at a Glance

In 1972, the “Atkins diet” became the first ketogenic diet to gain widespread appeal for weight management 1. Over the past 50 years, the Atkins brand has helped millions of people achieve their personal weight loss and health goals. Dr. Robert Atkins, a trailblazing cardiologist, developed the Atkins diet from his study of published in the scientific literature, where he noticed that restricting carbohydrate fundamentally changed human metabolism. Moving forward to today, more than 100 clinical studies have been published on low carb diets. Dr. Atkins challenged the status quo weight loss methods of his time by proposing a nutritional approach based on eating right, not less. This led to a keto-based diet that reduced sugar and carbohydrates, while introducing an increase in healthy fats and fiber-rich vegetables 2. Today, our story continues with a mission: To make eating right a part of everyday life through our advocacy, education, innovation, and products.

Trustworthiness of Atkins Products and Content

The Atkins brand has over 50 years of experience educating the public about the benefit of low carb eating through research and studies. We have a team of experienced scientists in the nutrition field that review every article, including the blogs, published on the Atkins website. We keep an internal research library that documents and categorizes research that supports lower carbohydrate approaches to nutrition and health.

The Atkins brand has decades of experience designing delicious products that support the low carbohydrate lifestyle with high protein or fiber, and with no added sugars. We test our products at third-party laboratories to verify they have a minimal impact on blood sugar.

Our History

The Atkins lifestyle began in 1963 when Dr. Atkins challenged the status quo weight loss methods of the time and proposed a nutritional approach grounded on eating right, not less. His method was based on studies that showed carbohydrate restriction was a healthy alternative to calorie restriction as it provided weight loss results, without significant hunger 4.

These are some of the significant milestones in our history:

  • was created in 1996 with the purpose of educating consumers about the science supporting low carbohydrate diets.
  • The concept of net carb was first introduced in 2002 when research demonstrated fiber had a minimal impact on blood sugar in an updated version of the book Dr. Atkins’ New Diet Revolution. This book remained on the bestseller list for 285 weeks, sold more than 15 million copies, and became the #1 Bestselling Avon paperback of all time.
  • The first randomized controlled trial demonstrating the safety and efficacy of the Atkins diet was published in the Annals of Internal Medicine in 2004. 
  • In 2007, A-Z study was published, showing that Atkins was more effective for weight loss than other interventions.
  • The American Diabetes Association recognized low carbohydrate diets as a viable option for managing blood sugar in people with diabetes in 2018 5.

Today, we continue to make an impact on millions of people looking to reach their dietary and health goals through the Atkins lifestyle.

Our Mission

Our purpose is to improve global health by changing how people eat and their relationship to food in order to improve their overall health. Dr. Atkins believed that eating right—not less—could improve a patient’s health, reduce chronic issues, and aid in weight loss. Over the last 45 years, increasing evidence is revealing that Dr. Atkins was right. Atkins public health advocacy has played a significant role in updating dietary guidelines.

Controlling the things that the human body turns into sugar is the largest factor in eating right.The Atkins way of eating satisfies the body, creating greater energy, higher metabolism, and less stored fat 6. Through state-of-the-art research, education, and products, we offer people the tools they need to make the right food choices for their bodies.

Ketogenic diet: Is the ultimate low-carb diet good for you?

In medicine, we have been using it for almost 100 years to treat drug-resistant epilepsy, especially in
children. In the 1970s, Dr. Atkins popularized his very-low-carbohydrate diet for weight loss that began with a very strict two-week ketogenic phase. Over the years, other fad diets incorporated a similar approach for weight loss.

At 12 months the effects on weight reduction and improvements in cardiovascular risk factors largely disappear.
