Atkins diet's impact on heart health
The Atkins diet is a low-carbohydrate, high-fat, high-protein diet devised by Robert Atkins in the 1970s. It promotes the unrestricted consumption of meat, cheese, eggs, butter, mayonnaise, and other high-fat foods, while prohibiting bread, cereal, pasta, and other carbohydrates. The diet gained immense popularity in the early 2000s, with one in eleven North American adults claiming to follow it.
Impact on Heart Health
The Atkins diet's impact on heart health has been a subject of debate. On the one hand, some studies and organisations have raised concerns about its potential negative effects on cardiovascular health due to its high saturated fat content:
- The American Medical Association, American Dietetic Association, and American Heart Association have criticised the Atkins diet as being nutritionally unbalanced and potentially increasing the risk of heart disease.
- A 2000 study in the Journal of the American College of Nutrition found that the high-fat content of the Atkins diet, particularly saturated fats, could lead to increased oxidative stress on different organs, including the heart.
- The diet's author, Robert Atkins, had a history of heart attack, congestive heart failure, and hypertension, according to a medical report.
On the other hand, several studies and organisations have suggested that a low-carbohydrate diet like Atkins may have beneficial effects on heart health:
- A 2008 study in the New England Journal of Medicine showed that a low-carbohydrate diet had a more favourable effect on blood lipid levels than a Mediterranean or low-fat diet.
- A 2013 study found that low-carb diets were equally effective as Mediterranean diets in improving cardiovascular risk factors for people with diabetes.
- A 2010 study by Temple University, published in the Annals of Internal Medicine, concluded that a low-carbohydrate diet is associated with favourable changes in weight loss and cardiovascular disease risk factors.
- The Harvard Nurses Study, which followed 120,000 female nurses for eight years, found that processed or rapidly digested carbs (like white flour and sugar) increase the risk of coronary heart disease. The Atkins diet advocates controlling carb intake and eliminating added sugar, which may reduce this risk.
- A 2015 meta-analysis in the BMJ concluded that saturated fats are not associated with an increased risk of heart disease.
- A 2017 study associated high carbohydrate intake with a higher risk of total mortality, while total fat and individual types of fat were related to lower total mortality.
- A 2021 study published in the American Journal of Clinical Nutrition found that a low-carb diet promoted heart health.
- Other studies have also suggested that low-carb diets may be beneficial for heart health, contradicting the idea that dietary fat is the main culprit for heart disease.

Popularity and decline
The Atkins diet was created by cardiologist Dr Robert Atkins in the 1970s. It is a low-carbohydrate, high-fat, high-protein diet that promotes the consumption of meat, cheese, eggs, and other high-fat foods, while forbidding bread, cereal, pasta, and other carbohydrates. The diet gained traction from Atkins' claim that restricting carbohydrates is the "key" to weight loss and that the diet offered a high-calorie way to stay thin forever.
The Atkins diet became popular in the early 2000s, with Dr Atkins' book, 'New Diet Revolution', becoming one of the top 50 best-selling books in history. It has sold 12 million copies and has been described as "the bestselling fad-diet book ever written". At the height of its popularity, one in eleven North American adults claimed to be on a low-carb diet such as Atkins. This large following was blamed for significant declines in the sales of carbohydrate-heavy foods like pasta and rice, with sales down 8.2% and 4.6% respectively in 2003. The diet's success was even blamed for a decline in Krispy Kreme sales.
Many companies tried to capitalise on the "low-carb craze" by releasing special product lines that were low in carbohydrates. However, despite its initial popularity, the percentage of American adults on the diet declined to two percent, and sales of Atkins brand products fell steeply in the second half of 2004. In 2005, Atkins Nutritionals, Inc. filed for bankruptcy following substantial financial losses.
There is no strong evidence of the diet's effectiveness in achieving long-term weight loss, and it has been criticised by medical experts for being nutritionally unbalanced and promoting the unlimited consumption of protein and saturated fat. Additionally, due to its high saturated fat content, the Atkins diet may increase the risk of heart disease. A medical report issued by the New York medical examiner's office a year after Atkins' death in 2003 showed that he had a history of heart attack, congestive heart failure, and hypertension. The Atkins diet has been criticised by the American Medical Association, American Dietetic Association, and the American Heart Association.
Despite the criticism and lack of strong evidence for its effectiveness, a 2021 review article observed that the Atkins diet was "coming back on the quackery scene again". An analysis by Forbes magazine found that the sample menu from the Atkins diet was one of the top five most expensive eating plans. Celebrities such as Kim Kardashian and Alyssa Milano have also partnered with Atkins to lose weight.

Effectiveness for weight loss
The Atkins diet is a low-carbohydrate, high-fat, high-protein diet. It was devised by Robert Atkins in the 1970s and gained widespread popularity in 2003 and 2004. The diet promotes the consumption of meat, cheese, eggs, and other high-fat foods, while carbohydrates like bread, cereal, and pasta are forbidden. Atkins claimed that carbohydrate restriction is crucial to weight loss and that his diet offered "a high-calorie way to stay thin forever".
The effectiveness of the Atkins diet for weight loss has been a topic of debate. Some people have experienced significant weight loss by following the Atkins diet. For example, Tanisha Washington, who was featured in People Magazine, lost 100 pounds by following the Atkins diet. Kim Kardashian also reportedly lost 60 lbs by following the diet after her second pregnancy.
There is some research to support the effectiveness of the Atkins diet for weight loss. A study published in the New England Journal of Medicine in 2008 showed that a low-carbohydrate diet like Atkins had a favorable effect on blood lipid levels and was more effective than a Mediterranean or low-fat diet. Another study published in the Annals of Internal Medicine in 2010 concluded that a low-carbohydrate diet was associated with favorable changes in weight loss and cardiovascular disease risk factors. Additionally, a 2013 study showed that low-carb diets are just as effective as Mediterranean diets in improving cardiovascular risk factors in people with diabetes.
However, there is also research questioning the effectiveness of the Atkins diet for long-term weight loss. A review study published in The Lancet concluded that there was no metabolic advantage to the Atkins diet and that dieters were simply eating fewer calories. There is also concern that the Atkins diet may increase the risk of heart disease due to its high saturated fat content. The American Medical Association, American Dietetic Association, and American Heart Association have criticized the diet as nutritionally unbalanced.
Overall, while some people have experienced weight loss on the Atkins diet, there is mixed evidence regarding its long-term effectiveness and potential impact on health. It is always advisable to consult a healthcare professional before starting any new diet, especially one that involves significant changes to your eating habits, like the Atkins diet.

Legacy
The Atkins diet is usually recommended for weight loss. Proponents of the diet claim that one can lose weight while eating as much protein and fat as they want, as long as they avoid foods high in carbohydrates. The diet's popularity led to a decline in the sales of carbohydrate-heavy foods like pasta and rice, and companies tried to capitalise on the trend by releasing special low-carb product lines.
Controversies
The Atkins diet has been criticised by the American Medical Association, American Dietetic Association, and the American Heart Association as nutritionally unbalanced. The diet has also been blamed for increasing the risk of heart disease due to its high saturated fat content. A medical report issued by the New York medical examiner's office a year after Atkins' death showed that he had a history of heart attack, congestive heart failure, and hypertension. A study by the Journal of the American College of Nutrition in 2000 also concluded that the Atkins diet delivers a strong boost to free radical production, thereby increasing oxidative stress on different organs.
The idea of a metabolic advantage of low-carbohydrate dieting has been criticised and refuted by experts. David L. Katz, for example, characterised Atkins' claim as "nonsense". Additionally, Atkins did not publish any clinical data on his patients and has been criticised for making unsupported statements about health.
