The Atkins diet is a low-carb, high-fat, high-protein diet that was created by cardiologist Robert Atkins in the 1960s. The diet focuses on eating plenty of fat and protein while severely restricting carbohydrates, especially in the early stages. The goal is to change the body's metabolism by forcing it to use fat as its primary source of energy instead of carbohydrates. This is achieved by limiting net carbs, which are calculated by subtracting the fibre content from the total number of carbohydrates in grams. While the diet allows unlimited consumption of meat, fatty fish, eggs, and other high-fat foods, it restricts carbohydrates such as sugar, white bread, white rice, and pasta. The Atkins diet has been both popular and controversial, with proponents claiming it is an effective way to lose weight and suppress appetite, while critics argue that it may lead to serious health problems due to its high-fat content and exclusion of healthy foods.

What You'll Learn
Phases of the Atkins diet
The Atkins diet is a low-carbohydrate, high-fat, high-protein diet. It is usually recommended for weight loss. The diet is divided into four phases, each with specific guidelines and goals. Here are the four phases of the Atkins diet:
Phase 1: Induction
This is the initial weight loss phase, where dieters are instructed to consume under 20 grams of carbohydrates per day for the first two weeks. The focus is on eating high-fat, high-protein foods and low-carb vegetables, such as leafy greens. This phase kick-starts weight loss by encouraging the body to use fat as its primary source of energy.
Phase 2: Balancing
In this phase, dieters slowly reintroduce a limited variety of carbohydrates back into their diet. This includes adding more nuts, low-carb vegetables, and small amounts of fruit. The goal is to continue weight loss while gradually increasing carbohydrate intake.
Phase 3: Fine-Tuning
As dieters approach their goal weight, they can further increase their carbohydrate intake. In this phase, dieters add more carbs until their weight loss slows down. The aim is to find a balance where weight loss continues but at a slower pace.
Phase 4: Maintenance
In the final phase, dieters have reached their "happy weight" and can now focus on maintaining their weight loss. They can eat as many healthy carbohydrates as their body can tolerate without regaining weight. This phase is about discovering individual carbohydrate tolerance and maintaining a stable weight.
It is important to consult a registered dietitian or physician before starting the Atkins diet or any other weight-loss programme. While the diet can lead to weight loss, it has also been criticised for its high saturated fat content, which may increase the risk of heart disease and raise LDL (bad) cholesterol.

Foods to avoid
The Atkins diet is a low-carbohydrate, high-fat, high-protein diet. It involves eating plenty of fat, some protein, and very few carbs. The diet recommends limiting or avoiding the following foods:
Sugar:
The Atkins diet recommends limiting or avoiding sugar, which is found in soft drinks, fruit juices, cakes, candy, and ice cream. "Diet" and "low-fat" foods are also best avoided, as these are sometimes very high in sugar.
Refined grains:
White bread, white rice, and white pasta are all highly refined grain products that are best limited or replaced with whole grain alternatives.
High-carb fruits:
Fruits like bananas, apples, oranges, pears, and grapes are high in carbohydrates and should be avoided, especially during the induction phase.
Starchy vegetables:
Potatoes and sweet potatoes are examples of starchy vegetables that are high in carbohydrates. These should be limited or avoided, especially in the early stages of the diet.
Legumes:
Legumes, such as lentils, beans, and chickpeas, are also recommended to be limited or avoided, especially during the induction phase.
It is important to note that the Atkins diet has been controversial, with some experts expressing concerns about its high-fat content and potential health risks. It is always advisable to consult a healthcare professional before starting any new diet, especially restrictive diets like Atkins.

The Atkins diet recommends eating foods that are low in carbohydrates, such as:
- Fats and oils: Avocado, nuts and seeds, olive oil, and coconut oil.
- Fish: Fatty fish like salmon, trout, sardines, and mackerel.
- Poultry: Chicken, turkey, and other lean meats.
- Meat: Beef, pork, lamb, and bacon.
- Eggs: Omega-3 enriched or pastured eggs.
- Dairy: Butter, cream, cheese, and sour cream.
- Vegetables: Low-carb vegetables like kale, spinach, broccoli, asparagus, courgette, cucumber, lettuce, watercress, sprouts, and other leafy greens.
- Fruits: Low-carb fruits like avocado and olives.
- Drinks: Water, coffee, green tea, and dry wines with no added sugars.
It is important to note that the specific foods recommended in the Atkins diet depend on which phase of the chosen plan you are following. There are four phases, starting with the most restrictive and gradually getting easier. The first phase, for example, restricts carbohydrates to under 20 grams per day, while the third phase allows for more carbs to be added to the diet.

Benefits of the Atkins diet
The Atkins diet is a low-carbohydrate, high-fat, and high-protein diet. It was created by cardiologist Dr Robert C. Atkins in the 1960s, who believed that carbohydrates, not fats, were responsible for health problems and weight gain. The diet has been popular since the 1970s and has stood the test of time, with many people worldwide still using it today.
There are several benefits to the Atkins diet. Firstly, it can be easier to follow than other diets that require more planning and calorie counting. The Atkins diet does not require calorie counting, and you can eat as much protein and fat as you want. This can be beneficial for those who feel hungry on other diets, as protein and fat suppress the appetite.
Secondly, the Atkins diet can lead to rapid weight loss, especially in the first few weeks. This is because the body will begin to burn stored fat for fuel instead of carbohydrates. The diet's high-fat content can also help with feelings of fullness, reducing the urge to snack.
Thirdly, the Atkins diet may have positive health impacts beyond weight loss. A 2013 study found that a low-carb, high-fat diet improved the headache symptoms of twin sisters. A 2004 study also showed that patients with narcolepsy experienced improvements in daytime sleepiness while on a low-carb diet. Additionally, the Atkins diet may help to improve blood pressure, cholesterol levels, and triglycerides, as well as decrease inflammation, thereby reducing risk factors for heart disease.
Finally, the Atkins diet is flexible and can be adapted to suit individual needs. There are four phases to the standard Atkins diet, but some people may start at a later phase. For example, vegans and vegetarians can substitute meat with plant-based sources of healthy fats and proteins, such as avocado, nuts, seeds, and olive oil.

Drawbacks of the Atkins diet
The Atkins diet is a low-carbohydrate, high-fat, high-protein diet. It was created by Dr. Robert C. Atkins, who wrote a bestselling book about it in 1972. The diet has been the subject of some controversy, with some studies showing that it may have negative health impacts. Here are some of the potential drawbacks of the Atkins diet:
Potential Negative Impact on Health:
The Atkins diet has been criticised for its high saturated fat content, which may increase the risk of heart disease. The American Heart Association warned that high-fat, high-protein, low-carbohydrate diets could increase oxidative stress on different organs, including the heart muscle. This, coupled with the reduced fibre intake associated with a low-carb diet, can increase the risk of cancer of the lungs and gastrointestinal tract. The diet may also increase levels of LDL (bad) cholesterol, which can have negative health consequences.
Lack of Long-Term Weight Loss Benefits:
While the Atkins diet may lead to faster weight loss in the short term, studies have shown that there is no significant difference in weight loss compared to other diets after 12 months. The initial weight loss advantage is likely due to increased water loss, and after this initial period, low-carb diets produce similar fat loss to other diets with a similar caloric intake.
Other Potential Health Risks:
The high protein content of the Atkins diet could lead to health issues such as hyperuricemia (causing joint pain and gout) and hypercalcuria (which can lead to kidney stones, hypocalcemia, and osteoporosis). A Harvard study also indicated that high protein intake may cause permanent loss of kidney function in individuals with reduced kidney function.
Altered Gut Microbiota:
Studies suggest that a low-carb diet may alter the gut microbiota, potentially having a detrimental effect on the production of short-chain fatty acids (SCFAs) which are important for gut and general health.
Practicality and Enjoyment:
The Atkins diet may be difficult to follow long-term due to its restrictions on carbohydrates, which may make it unrealistic and unenjoyable for some people.
Side Effects:
Common side effects of low-carb diets include nausea, dizziness, constipation, headaches, fatigue, and bad breath.
It is always recommended to consult a healthcare professional or registered dietitian before starting any new diet, especially restrictive diets like the Atkins diet.
