Dr. Atkins' New Diet Revolution, penned by Robert C. Atkins, M.D., presents a comprehensive approach to weight loss centered around a low-carbohydrate eating plan. The book serves as a guide, offering essential medical and nutritional information, a carbohydrate gram counter, low-carb meal plans, and recipes for various dishes. The core promise is a healthier, fitter, and happier life through dietary changes.
The Core Principles of the Atkins Diet
The Atkins Diet, formally known as the Atkins Nutritional Approach, was developed in the 1960s by cardiologist Robert C. Atkins. The diet posits that the typical low-fat, high-carb American diet is the culprit behind obesity and related health issues like type 2 diabetes and heart disease. It challenges the notion of avoiding fatty cuts of meat and encourages the consumption of more protein and fat while limiting carbohydrates, especially sugar and refined carbs. Atkins argued that excessive carb intake leads to blood sugar imbalances, weight gain, and heart problems.
The Four Phases of the Atkins Diet
The Atkins Diet is structured into four distinct phases, each with specific guidelines:
Phase 1: Induction. This initial phase is the most restrictive, drastically reducing carbohydrate intake to approximately 10% of daily calories. The focus is on consuming protein-rich foods like fish, shellfish, poultry, meat, eggs, and cheese, without limiting oils and fats. Most fruits, sugary baked goods, breads, pastas, grains, nuts, and alcohol are off-limits. Drinking at least eight glasses of water a day is also recommended. The goal is to shift the body into a state of ketosis, where it burns fat for energy due to the lack of available carbohydrates.
Phase 2: Balancing. In this phase, a minimum of 12 to 15 grams of net carbs are consumed as foundation vegetables. Foods with added sugar remain off-limits. Some nutrient-dense carbs, such as more vegetables, berries, nuts, and seeds, can be slowly reintroduced as weight loss continues.

Phase 3: Pre-maintenance. This phase involves gradually expanding the range of foods, including fruits, starchy vegetables, and whole grains. Carb intake can be increased by about 10 grams each week, but it must be reduced if weight loss stalls.
Phase 4: Lifetime maintenance. This final phase is reached when the goal weight is achieved. The aim is to find a personal carbohydrate balance that allows for weight maintenance.
Practical Implementation and Meal Planning
Dr. Atkins' New Diet Revolution provides practical advice for incorporating the Atkins Diet into daily life. The book includes lists of acceptable foods for each phase, along with sample meal plans and recipes. For example, a breakfast option could be egg-filled avocado with prosciutto. Snacks, typically limited to two per day, might include Atkins Diet products like chocolate shakes or granola bars. The diet emphasizes tracking net carbs, calculated by subtracting the fiber content from the total carbohydrate content of a food item.
Claims and Counterclaims: Examining the Evidence
The Atkins Diet claims that its approach to carbs will burn off your body's fat stores, control your blood sugar, and help you achieve optimal health. It also asserts that exercise isn't needed for weight loss. While the diet suggests significant weight loss is possible in the first two weeks of phase 1, it acknowledges that these results aren't typical and may be due to water weight loss.
Studies show that low-carb diets like the Atkins Diet are no more effective for weight loss than standard weight-loss diets over the long term. Weight loss on the Atkins Diet is primarily attributed to lower overall calorie intake from eating fewer carbs. Some studies suggest that limited food choices and increased satiety from protein and fat contribute to weight loss.

The Atkins Diet claims to prevent or improve serious health conditions, such as metabolic syndrome, diabetes, high blood pressure, and heart disease. While most weight-loss diets may temporarily improve blood cholesterol or blood sugar levels, some very low-carb diets can restrict carbs to the point of causing nutrient or fiber deficiencies, leading to health problems like constipation, diarrhea, and nausea. Restricting carbohydrates to less than 20 grams a day, as recommended in phase 1, can also result in ketosis.
Concerns and Considerations
It's crucial to consult a healthcare provider before starting the Atkins Diet, especially for individuals taking diuretics, insulin, or oral diabetes medications. People with severe kidney disease should avoid the diet. Some reviewers have also noted potential long-term negative effects on the kidneys and an increased risk for heart disease and cancer.
A Historical Perspective
The low carbohydrate approach is not new. It was used in England more than a century ago and made popular by William Harvey, an ENT surgeon, who prescribed a low carbohydrate diet for William Banting, an obese carpenter who had been having a great difficulty losing weight. Banting was able to lose weight and as a service, he published in 1863 a small booklet entitled Letter on Corpulence Addressed to the Public , the first book to be published on obesity and one which popularized low carbohydrate diets. He has been called "Father of low carbohydrate diets" and was honored by his name being included in the dictionary as the verb "to bant" meaning "to diet". The low carbohydrate diet also been called a "Harvey-Banting diet" after the names of these pioneer.
The Atkins Diabetes Revolution
The Atkins Diabetes Revolution plan is similar to the Atkins weight loss strategy: four levels of carbohydrate restriction are instituted. The induction phase restricts dieters to 20 g of carbohydrate. On the weight loss plan, this is recommended for about 2 weeks. In diabetes this is maintained until glycemic control is attained. In the latter stages, carbohydrates are added as long as weight loss or stability is maintained. For diabetes, carbohydrates are only reintroduced if glycemic control is acceptable. In the later phases, the Atkins Diabetes plan adds a Glycemic Ranking (AGR), derived from the glycemic index, glycemic load and net carbs. Preference is given to whole fruits and berries and juices and dried fruits are low on the list.
