The Atkins diet is a popular weight-loss plan based on eating fewer carbohydrates and more fatty foods. It was first introduced by Dr Robert Atkins, an American cardiologist, in 1972. The diet has four phases, with the first being an induction phase where the body switches from burning carbs to burning fat, a process called ketosis. During this phase, people are advised to eat protein, fat, and only 20 grams of carbs in vegetable form daily. The Atkins diet has been criticised by some experts as nutritionally unbalanced and potentially unhealthy due to its high saturated fat content, which may increase the risk of heart disease. However, proponents of the diet argue that it can lead to effective weight loss and various health improvements.

What You'll Learn
What foods to eat
The Atkins diet is a low-carbohydrate, high-fat, high-protein diet. It was created by Dr Robert C. Atkins, who wrote a best-selling book about it in 1972. The diet has been criticised by some for being nutritionally unbalanced and increasing the risk of heart disease due to its high saturated fat content. However, proponents of the diet claim that it is an effective way to lose weight.
The diet involves restricting net carbs (including those in vegetables) and emphasising protein and healthy fats. Net carbs are defined as grams of carbs minus grams of fibre and sugar alcohols. The Atkins diet is typically split into four phases, with the first phase involving eating under 20 grams of carbs per day for two weeks, with a focus on high-fat, high-protein foods and low-carb vegetables. In the second phase, more nuts, low-carb vegetables and small amounts of fruit are added to the diet. The third phase involves adding more carbs until weight loss slows down. The final phase is about maintenance, where individuals can eat as many healthy carbs as their body can tolerate without regaining weight.
So, what foods can you eat on the Atkins diet? During the first phase, all meat, fish and shellfish are allowed, as well as eggs and cheese. Vegetables are also a key part of this phase, with 12 to 15 grams of your daily carbs coming from leafy greens and other low-carb vegetables. Water is essential, but coffee and green tea are also approved beverages. Alcohol is permitted in small amounts, with dry wines being the best option.
In the second phase, certain fruits can be incorporated into the diet. In the third and fourth phases, more carbs are added, with the fourth phase being about finding the balance of healthy carbs that works for your body.

What foods to avoid
The Atkins diet is a low-carbohydrate, high-fat, high-protein diet, usually recommended for weight loss. It was created by Dr Robert Atkins, an American cardiologist, in the 1970s. The diet has been criticised by some for its high saturated fat content, which may increase the risk of heart disease.
The diet's core principle is that the main cause of weight gain is the consumption of refined carbohydrates, especially sugar, high-fructose corn syrup, and flour. When following the Atkins diet, it is important to avoid or limit the following foods:
- Sugar: found in soft drinks, fruit juices, cakes, candy, ice cream, and similar products.
- Refined grains: white bread, white rice, and white pasta.
- "Diet" and "low-fat" foods: these are sometimes very high in sugar.
- High-carb fruits: bananas, apples, oranges, pears, and grapes.
- Starchy vegetables: potatoes and sweet potatoes.
- Legumes: lentils, beans, chickpeas, and peas.
It is also important to pay attention to drinks, as these can be a significant source of hidden sugars and carbohydrates. Drinks to avoid include fruit juices, beer, and cocktails. Water should be your go-to beverage, and you should drink 6 to 8 glasses per day.

What drinks are allowed
The Atkins diet is a low-carbohydrate, high-fat, high-protein diet that is usually recommended for weight loss. It was developed by Dr Robert C. Atkins and has been the subject of several books since the 1970s.
The diet recommends drinking water as your primary beverage. Coffee and green tea are also acceptable drinks, as they are high in antioxidants and may offer health benefits.
Alcohol is permitted in small amounts. Dry wines with no added sugars are the best option, as other alcoholic drinks tend to be high in carbohydrates and sugars. Beer and cocktails, for example, should be avoided.
Diet soda is also a safe and acceptable drink on the Atkins diet, although it is not particularly nutritious. Tea is another option, although it does not provide as much energy as coffee. Tea should be drunk without milk, as dairy can add carbohydrates.

The four phases
The Atkins diet is a low-carbohydrate, high-fat, high-protein diet, usually recommended for weight loss. The diet was inspired by a low-carb approach published by Alfred W. Pennington and was popularised by Dr. Robert C. Atkins, who wrote a best-selling book about it in 1972.
Phase 1: Induction
This phase involves consuming under 20 grams of carbohydrates per day for the first two weeks. During this phase, dieters are instructed to eat high-fat, high-protein foods and low-carb vegetables like leafy greens. This phase is designed to kickstart weight loss.
Phase 2: Balancing
In this phase, dieters can slowly start adding more nuts, low-carb vegetables, and small amounts of fruit back into their diet. The focus is on finding a balance and continuing weight loss.
Phase 3: Fine-tuning
As dieters approach their goal weight, they can start introducing more carbohydrates into their diet. This phase is about finding the right balance of carbs that allows for continued weight loss without slowing down progress.
Phase 4: Maintenance
In the final phase, dieters can eat as many healthy carbohydrates as their body can tolerate without regaining weight. This phase is about maintaining the weight loss achieved in the previous phases and finding a long-term, sustainable approach to eating.
It is important to note that not everyone may need to follow all four phases. Some people may choose to skip the induction phase and include plenty of vegetables and fruits from the beginning. Additionally, it is always recommended to consult a registered dietitian or physician before starting a new weight-loss diet plan.

Health benefits and risks
The Atkins diet is a low-carbohydrate diet, usually recommended for weight loss. It involves eating nutrient-dense foods and limiting or avoiding foods with high carbohydrate content, such as sugar, refined grains, "diet" and "low-fat" foods, high-carb fruits, starchy vegetables, and legumes. The diet focuses on balancing protein, fat, and carb intake, with about 43% of food intake coming from healthy plant-based fat sources. The Atkins diet has been promoted as a way to lose weight without counting calories, and it has been popular worldwide since the 1970s.
Health Benefits
The Atkins diet has been associated with several potential health benefits, including:
- Weight loss: The diet has been shown to be effective for weight loss, with some people losing a significant amount of weight while following the plan.
- Improved cholesterol: Some studies have shown that the Atkins diet can lead to improved HDL ("good") cholesterol and lowered LDL ("bad") cholesterol levels.
- Improved blood sugar: Research suggests that low-carb diets like Atkins may result in greater improvements in blood sugar control compared to low-fat diets.
- Other health improvements: The Atkins diet may also lead to improvements in other health markers, such as triglycerides.
Health Risks
However, there are also potential health risks associated with the Atkins diet:
- Lack of long-term studies: While the Atkins diet has been shown to have short-term benefits, there is limited research on its long-term effects. It is unclear if the health benefits associated with low-carb diets like Atkins hold up over time or increase lifespan.
- Increased risk of certain diseases: Some experts believe that a diet high in fat and protein from animal sources, as the Atkins diet typically includes, can increase the risk of heart disease and certain types of cancer. However, this is a topic of debate among researchers, and the Atkins diet has evolved to include more lean meats and nutritious foods.
- Side effects: Eating a low-carb diet can cause side effects such as headaches, dizziness, weakness, fatigue, and "keto flu," which includes symptoms like nausea and brain fog.
- Nutritional deficiencies: Cutting out certain food groups, such as fruits and whole grains, may lead to nutritional deficiencies if not carefully planned.
- Social impact: Following a restrictive diet like Atkins can make it challenging to eat out at restaurants or attend social events, potentially impacting one's social life.
