What You'll Learn
Origins and popularity
The Atkins diet was created by Dr Robert Atkins, a trailblazing cardiologist who challenged the status quo weight-loss methods of his time. In the 1960s, health officials recommended a diet low in saturated fats but not low in sugars. However, recent research has shown that refined carbohydrates and sugars are risk factors for heart disease. In 1972, Dr Atkins first wrote about the dangers of a carb-rich diet, marking the beginning of the Atkins diet.
Dr Atkins made the controversial argument that a low-carbohydrate diet produces a metabolic advantage because "burning fat takes more calories so you expend more calories". He claimed that his diet was "a high-calorie way to stay thin forever". He cited a study in which he estimated this advantage to be 950 calories per day. However, a review study published in Lancet concluded that there was no metabolic advantage and that dieters were simply eating fewer calories.
The Atkins diet gained widespread popularity in 2003 and 2004. At its height, 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. Many companies tried to capitalise on the "low-carb craze" by releasing special product lines that were low in carbohydrates.
The popularity of the Atkins diet can be attributed to the freedom it offers to consume as much protein and fat as desired, while carbohydrate intake must be restricted to no more than 20 grams per day initially. The diet promotes the consumption of meat, cheese, eggs, and other high-fat foods such as butter, mayonnaise, and sour cream in unlimited amounts, while bread, cereal, pasta, and other carbohydrates are forbidden. Dr Atkins' book, *New Diet Revolution*, has sold 12 million copies and has been described as "the bestselling fad-diet book ever written".

Health concerns
The Atkins diet has been around since the 1960s, and has been a source of controversy for decades. It has been criticised by many medical professionals and organisations, including the American Medical Association, American Dietetic Association, and the American Heart Association.
The Atkins diet is a high-protein, high-fat, low-carbohydrate weight-loss plan. It promotes the unrestricted consumption of meat, cheese, eggs, butter, mayonnaise, and sour cream, while forbidding bread, cereal, pasta, and other carbohydrates.
Short-Term Effects
The Atkins diet can lead to short-term weight loss, which is likely due to increased water loss. However, this comes with several unpleasant side effects, including nausea, dizziness, constipation, headache, fatigue, and bad breath. Ketosis, a state where the body uses ketone bodies for energy instead of glucose, can also lead to metabolic dehydration, where the body consumes its own stored water, further increasing weight loss.
Long-Term Effects
The Atkins diet has been criticised for its potential negative long-term effects on health. The high saturated fat content may increase the risk of heart disease by boosting free radical production and increasing oxidative stress on different organs, particularly the heart muscle. This can have serious, even fatal, consequences.
The diet has also been linked to an increased risk of colon cancer, kidney stones, kidney disease, and osteoporosis. A Harvard study showed that high-protein diets may cause permanent loss of kidney function in individuals with reduced kidney function, which is a significant concern as many people may have undiagnosed kidney problems.
Additionally, the Atkins diet may increase the risk of cancer of the lungs and gastrointestinal tract due to increased oxidative stress and reduced fibre intake.
Nutritional Imbalance
The Atkins diet has been criticised as nutritionally unbalanced. It restricts carbohydrates, including whole grain, fruits, vegetables, and low-fat milk, which are important sources of nutrients and fibre. This can lead to a lack of essential vitamins, minerals, and fibre in the diet, which can have negative health consequences.
Lack of Clinical Data
Atkins did not publish any clinical data on his patients, and his claims of the diet's effectiveness have been criticised as unsupported. There is limited large-scale, randomised controlled trial evidence to support the long-term safety and effectiveness of the Atkins diet.
Alternative Weight Loss Methods
Alternative approaches to weight loss, such as high-carbohydrate, low-fat diets, have been shown to be more effective in producing long-term weight loss. These diets focus on increasing insulin sensitivity and reducing the risk of coronary heart disease.
In conclusion, while the Atkins diet may lead to short-term weight loss, it has the potential to cause serious long-term health issues. It is important to prioritise weight loss methods that are safe and sustainable, rather than following fad diets that can be harmful to overall health.

Studies and criticism
The Atkins diet has been criticised by the American Medical Association, American Dietetic Association, and the American Heart Association as nutritionally unbalanced. The high saturated fat content of the diet has been linked to an increased risk of heart disease. A report by the New York medical examiner's office revealed that Atkins himself had a history of heart attack, congestive heart failure, and hypertension.
The diet has also been criticised for its potential negative impact on kidney function. A Harvard study showed that high-protein diets may cause permanent loss of kidney function in people with reduced kidney function, which is a relatively common condition. The American Diabetes Association has also cautioned against the use of low-carbohydrate diets, citing the importance of including foods containing carbohydrates and whole grains, fruits, vegetables, and low-fat milk.
The Atkins diet has also been criticised for being unsustainable and leading to an insignificant difference in weight loss compared to low-calorie, low-fat diets. The diet restricts carbohydrate intake to less than 24% of energy, which is difficult to maintain over a long period. The two longest (12-month) randomised investigations showed that weight loss due to low-carbohydrate diets is often unsustainable when carbohydrates are reintroduced.
Despite the criticism, some studies have shown positive results for the Atkins diet. A Stanford University School of Medicine study found that the Atkins diet led to more weight loss and had the most benefits in terms of cholesterol and blood pressure compared to three other popular diets. The study also found that protein is more satiating than carbohydrates or fats, which may have helped those in the Atkins group eat less without feeling hungry. However, the women in the Atkins group ended the one-year period with a final average weight loss of 10 pounds, regaining some of the weight lost in the first half of the study.
The Atkins diet gained widespread popularity in 2003 and 2004, with one in eleven North American adults claiming to be on a low-carb diet. This large following was blamed for significant declines in the sales of carbohydrate-heavy foods. However, the popularity of the diet has since waned, with a 2021 review article observing that the diet was "coming back on the quackery scene again".

Phases and food recommendations
The Atkins diet is a low-carbohydrate, high-fat, and high-protein diet. It was created by Dr Robert C. Atkins, who wrote a bestselling book about it in 1972. The diet gained widespread popularity in 2003 and 2004, with one in eleven North American adults claiming to be on a low-carb diet such as Atkins.
The Atkins diet consists of four phases, each with specific food recommendations and restrictions:
Phase 1: Induction
During the induction phase, individuals are allowed only 20 grams of carbohydrates per day for the first two weeks. Carbohydrates during this phase come mainly from low-starch vegetables and salads. Protein and fat intake are unrestricted, with foods such as meat, fish, chicken, eggs, and cheese recommended.
Phase 2: Balancing
In the second phase, individuals slowly reintroduce whole food carbohydrates while continuing to lose weight. The aim is to find out how many carbohydrates an individual can eat while still losing weight. This phase continues until the individual is within 5-10 pounds of their target weight. Carbohydrate intake is increased by 10 grams each week, with a daily allowance of 25 to 50 net carbs.
Phase 3: Fine-Tuning
In the third phase, individuals continue to add a wider variety of carbohydrate sources to their diet while carefully monitoring their weight. Net carb intake varies between individuals but typically ranges from 40 to 80 grams per day. This phase lasts for at least one month after reaching the desired weight.
Phase 4: Maintenance
The final phase focuses on maintaining the target weight by continuing a predominantly low-carbohydrate diet for life. By this stage, individuals should understand how many carbohydrates they can consume to maintain their weight. The recommended daily net carb intake is 80 to 100 grams.
Throughout the Atkins diet, certain foods are recommended, while others are restricted or limited. Preferred foods include whole, unprocessed options with a low glycemic index. Recommended foods include:
- Meats: beef, pork, lamb, chicken, bacon, etc.
- High-fat foods: butter, mayonnaise, sour cream, etc. (in moderation)
- Eggs
- Low-carb vegetables: leafy greens, etc.
- Nuts and seeds
- Berries
- Cheese
Foods to limit or avoid include:
- Sugar: found in soft drinks, fruit juices, cakes, candy, ice cream, etc.
- Refined grains: white bread, white rice, white pasta
- "Diet" and "low-fat" foods: often high in sugar
- High-carb fruits: bananas, apples, oranges, grapes, etc.
- Starchy vegetables: potatoes, sweet potatoes
- Legumes: lentils, beans, chickpeas, etc.
It is important to note that the Atkins diet has been controversial and criticized by some medical organizations due to its high saturated fat content and potential health risks. These include an increased risk of heart disease, kidney problems, and gout. The diet may also be difficult to follow in the long term due to its restrictions. As with any diet, it is essential to consult a healthcare professional before starting and ensure a balanced and individualized approach.

Atkins' legacy
The Atkins diet was created by Dr. Robert Atkins, a trailblazing cardiologist who challenged the status quo weight-loss methods of his time. He first wrote about the dangers of a carb-rich diet in 1972, marking the beginning of the Atkins diet's legacy.
Atkins' early books, such as "Dr. Atkins' New Diet Revolution," made a controversial argument that a low-carbohydrate diet produces a metabolic advantage. He claimed that "burning fat takes more calories, so you expend more calories," and his diet was thus a "high-calorie way to stay thin forever." This idea of a "metabolic advantage" has since been disproven by studies. Despite the controversy, Dr. Atkins' book sold 12 million copies, with some sources citing sales of 15 million, and is described as "the bestselling fad-diet book ever written."
The Atkins diet gained widespread popularity in 2003 and 2004, with one in eleven North American adults claiming to be on a low-carb diet. This large following was blamed for significant declines in the sales of carbohydrate-heavy foods, and many companies tried to capitalize on the "low-carb craze" by releasing special product lines. The diet's popularity also led to the formation of the Atkins Nutritionals company in 1989, which marketed and sold Atkins-branded products. Celebrities such as Kim Kardashian have also contributed to the popularity of the Atkins diet by publicly endorsing it.
However, the diet has also faced significant criticism and controversy. It has been criticized by the American Medical Association, American Dietetic Association, and the American Heart Association as nutritionally unbalanced and potentially dangerous. There are concerns about the high-fat content of the diet, and studies have shown that it may increase the risk of heart disease, kidney damage, and gout, among other health issues. Additionally, the diet has been criticized for its lack of long-term data and unsupported statements about health.
Despite the criticism and controversy, the Atkins diet has left a lasting impact on the weight loss industry. It has sparked a larger conversation about the role of carbohydrates and fats in a healthy diet, and its popularity has influenced the development of other low-carb diets and products.
