The Atkins diet is a high-protein, low-carbohydrate weight-loss plan. Created by cardiologist Robert Atkins in the 1960s, the diet has been around for decades and has some benefits, such as cutting calories and controlling blood sugar. However, it has also been criticised by medical professionals for being linked to health issues including kidney stones, kidney disease, and even osteoporosis. The diet has four phases, starting with very few carbs and gradually eating more until the desired weight is reached. While it can be easier to follow than other diets, it may not be suitable for everyone, and it is always recommended to consult a healthcare professional before starting any new diet plan.

Atkins diet foods to eat
The Atkins diet is a low-carbohydrate, high-protein, high-fat weight-loss plan. It was created by Dr Robert Atkins, an American cardiologist, in the early 1970s.
The diet has four phases, and in the first, individuals are restricted to under 20 grams of carbohydrates per day for two weeks. This initial phase is called the induction phase, and it involves eating high-fat, high-protein foods, and low-carb vegetables.
Foods to eat during the induction phase include:
- Meat, such as beef, pork, lamb, chicken, and bacon
- Fatty fish and seafood, including salmon, trout, sardines, and mackerel
- Eggs, ideally omega-3 enriched or pastured
- Low-carb vegetables, such as kale, spinach, broccoli, and asparagus
- Water, coffee, and green tea are the best drinks
In the later phases, some foods that were forbidden in the induction phase can be reintroduced, and individuals can eat as many healthy carbohydrates as their body can tolerate without regaining weight. However, it is important to note that fruits and grains are still restricted, especially in the early stages of the diet.

Atkins diet foods to avoid
The Atkins diet is a low-carb, high-protein, high-fat weight-loss plan. It was created by Dr. Robert Atkins, an American cardiologist, in the early 1970s. The diet has evolved over time and now encourages people to eat more high-fibre vegetables and exercise.
Sugar
Sugar is found in soft drinks, fruit juices, cakes, candy, ice cream, and similar products. These products contain high levels of glucose, which can cause a glucose spike in the blood.
Refined Grains
White bread, white rice, and white pasta are all refined grains that should be avoided. These foods are high in carbohydrates and can hurt your progress on the Atkins diet.
"Diet" and "Low-Fat" Foods
Foods labelled as "diet" or "low-fat" are sometimes very high in sugar and should be avoided or limited.
High-Carb Fruits
Bananas, apples, oranges, pears, and grapes are high in carbs and should be avoided, especially during the induction phase of the diet.
Starchy Vegetables
Potatoes and sweet potatoes are examples of starchy vegetables that are high in carbohydrates and should be limited or avoided, especially during induction.
Legumes
Legumes, such as lentils, beans, and chickpeas, are not suitable during the induction phase of the diet. However, they can be reintroduced at a later stage.
Dairy
Although dairy is typically a low-carb food group, it does contain carbs, so it is important to limit your intake.
Processed Meats
It is recommended to avoid or limit processed meats, such as bacon, and opt for fattier cuts of meat like ribeye steak or chicken thighs.
Alcohol
Alcoholic beverages, especially beer and cocktails, tend to be high in carbs and sugar. It is best to stick to dry wines with no added sugars and limit your intake.
It is always advisable to consult a healthcare professional or a registered dietitian before starting any new diet, especially a restrictive one like the Atkins diet.

Atkins diet drinks
The Atkins diet is a low-carbohydrate weight-loss plan. It is also known as a very low-carb ketogenic diet (keto). People on the Atkins diet are told to avoid or limit foods and drinks containing sugar, such as soft drinks, fruit juices, cakes, and candy. Coffee is also forbidden on the Atkins diet, as it contains caffeine.
There are some drinks that are acceptable on the Atkins diet. These include:
- Water
- Green tea, which is high in antioxidants
- Alcohol, but only in small amounts and limited to dry wines with no added sugars
The Atkins diet has been controversial, with some medical professionals denouncing it. Critics of the diet point to potential health risks, including increased frequency of colon cancer, formation of kidney stones, kidney disease, and osteoporosis. However, proponents of the diet argue that it can lead to significant weight loss and improved cholesterol levels.
The Atkins website also sells a line of ready-to-drink shakes, which are packaged in recyclable TetraPak cartons to reduce their carbon footprint.

Atkins diet phases
The Atkins diet is a low-carbohydrate, high-protein, and high-fat weight-loss plan. It was popularized by Dr. Robert C. Atkins, who wrote a best-selling book about it in 1972. The diet has been controversial, with some experts warning against potential negative health consequences, while others tout its effectiveness for weight loss. The diet consists of four phases, each with specific guidelines for food intake and carbohydrate restrictions.
Phase 1: Induction
During the induction phase, individuals are instructed to consume less than 20 grams of carbohydrates per day for the first two weeks. This phase emphasizes eating high-fat and high-protein foods, along with low-carb vegetables like leafy greens. It is meant to induce a state of ketosis, where the body burns fat for energy instead of carbohydrates.
Phase 2: Balancing
In this phase, individuals slowly introduce more carbohydrates back into their diet. The goal is to find a tolerable level of carbohydrate intake that still allows for weight loss. This phase involves a trial-and-error process, as individuals adjust their carb intake based on their weight loss goals and how their body responds.
Phase 3: Fine-Tuning
Here, individuals continue to fine-tune their carbohydrate intake to find the optimal level for maintaining their weight loss. This phase focuses on finding a balance between carb intake and weight management, making adjustments as needed. It is a gradual process of discovering the right combination of nutrients to sustain a healthy weight.
Phase 4: Maintenance
The final phase of the Atkins diet is about making the low-carb lifestyle a permanent part of one's routine. It involves adhering to the principles learned in the previous phases and making long-term dietary choices to maintain a healthy weight. This phase emphasizes the importance of consistency and may involve ongoing adjustments to keep weight loss results.
While the Atkins diet has been associated with weight loss, it is important to consult with a healthcare professional before starting any new diet, especially one that involves significant dietary restrictions like the Atkins plan. Additionally, the potential risks associated with long-term adherence to this diet, such as increased risk of certain types of cancer and heart disease, should be carefully considered.
