A cardiologist named Robert C.Atkins proposed a diet plan called the Atkins diet in 1960. It is also known as Atkins nutritional approach. The main focus of this diet plan is more proteins and fats but limited carbohydrates. The Atkins diet comprises four phases for maintaining the ideal body weight. It is directed toward a long life with a healthy diet plan. The specific eating habits of the Atkins diet provide better health.

  • It controls the triglycerides level and improves blood cholesterol.

What Is the Atkins Diet Plan?

  • The Atkins diet comprises carbohydrates, proteins, and fats in balanced proportions.

  • It modifies the typical American diet consisting of low-fat, high carbohydrates into an adequate diet.

  • In the Atkins diet, the individual need not avoid meat-containing fat, as it focuses only on controlling carbohydrates.

  • A diet rich in sugar, refined carbs, and white flour may result in imbalances in the sugar level, and the individual gains weight. But the Atkins diet restricts such dietary plans.

  • An Atkins diet can be modified according to the individual's requirements, like a vegan diet or a vegetarian diet.

  • It also emphasizes the health problems that might occur due to a low carbohydrate diet.

What Are the Four Different Phases of the Atkins Diet?

The individual can start any of the three phases depending on the weight goals.

  • Phase 1 - Induction - The individual must restrict the diet by eating only 20 grams of carbohydrates. It should be particularly from vegetables. As per the nutritional guidelines, a person should intake 45 to 65 percent of carbohydrates from the daily calories. But the Atkins diet comprises only 10 percent of carbohydrates. It primarily focuses on green vegetables like beans, broccoli, and cucumber. Every meal should contain protein obtained from foods like fish, cheese, butter, egg, soy-based foods, and meat. The induction phase restricts alcohol, baked food items, and nuts. The individual following this phase must drink eight glasses of water daily. This phase lasts for about two weeks, depending on the weight loss goals.

  • Phase 2 - Balancing - This phase is a continuation of the induction phase. The individual should continue eating 12 to 15 gms of carbohydrates from the vegetables. The nutrient-rich foods like nuts, berries, and seeds can also be added to the diet in this phase. The individual should stay in this phase until the body weight is about 4.5 kilograms from the goal weight. Drinks like coffee and green tea can be taken by the individuals on the Atkins diet as it has antioxidant properties.

  • Phase 3 - Pre-Maintenance - In this phase, the individual can start eating fruits and whole grains along with vegetables. The individual can add ten grams of carbohydrates to the diet each week. This phase should be continued until the individual reaches the goal weight.

  • Phase 4 - Lifetime Maintenance - After reaching the goal weight, the individual can repeat the same process for the entire life.

What to Expect After the Atkins Diet?

  • An individual can lose up to 6.8 kilograms in phase 1.

  • Initially, the body tries to lose water content. But the unwanted weight can be reduced during phase 2 and phase 3.

  • There is less calorie intake due to restrictions on the carbohydrate level.

  • The protein and fat give a stomach full feeling to the individual.

  • Recent changes in the Atkins diet include the intake of extra salt and supplements like vitamin tablets for nourishment.

What Are the Risk Factors of the Atkins Diet?

  • Diabetic patients must consult a medical professional before proceeding with the Atkins diet, as it involves changes in the food.

  • Animal foods rich in high-fat content can increase the risk of cancer.

  • Restricting the carbs suddenly in the diet makes the individual weak and exhausted.

  • Constipation is the main side effect of low carbohydrate intake. Some individuals have diarrhea due to the intake of animal foods.

  • The individual might experience dizziness and headache due to the change in diet plan.

  • Nutritional deficiency might occur due to insufficient fiber content in the Atkins diet.

  • Since phase 1 restricts the carbohydrate intake to less than 20 grams, it can result in serious medical conditions like ketosis. It is a condition in which the body does not have enough glucose for energy. It results in the breakdown of the fat stored in the body. This eventually leads to ketone buildup in the body. Ketosis can cause nausea and bad breath for some people.

  • The patients taking medications like diuretics, Insulin, and oral diabetic drugs should not follow the Atkins diet as it interferes with the drug metabolism (it needs to be followed under medical supervision teams like doctors and dietitians).

  • The Atkins diet should not be followed by breastfeeding and pregnant women as it influences the baby's development.


In recent years, the Atkins diet has evolved by encouraging the individual to eat more vegetables rich in fiber content. Research has shown that people can regain weight once after stopping the Atkins diet plan. Calorie restriction for the short term can help people lose weight. However, the individual must consult a dietician before restricting the calories for the long term. Unlike other diet plans, exercise is not recommended in the Atkins diet. According to the Atkins diet, exercise helps in maintaining the ideal body weight and is vital for leading a healthier lifestyle but it is not essential for losing bodyweight. However, research says the Atkins diet cannot be tolerated for the entire life. It can only be followed for a phase.
