The Atkins diet is a low-carbohydrate diet, usually recommended for weight loss. It was created by Dr Robert C. Atkins in 1972 and has since been updated to include two versions: Atkins 20 and Atkins 40. The diet is based on the idea of changing one's metabolism so that the body burns fat for energy instead of glucose, a process known as ketosis. During the induction phase, individuals are advised to limit their daily net carb intake to an average of 20 grams to kickstart fat burning. While the Atkins diet restricts certain food groups, full-fat dairy products such as butter, cheese, cream, and yoghurt are encouraged.

What You'll Learn
Atkins diet and weight loss
The Atkins diet is a low-carb diet, usually recommended for weight loss. It was initially considered unhealthy, mostly due to its high saturated fat content. However, proponents of the Atkins diet claim that you can lose weight while eating as much protein and fat as you want, as long as you avoid foods high in carbohydrates. The Atkins diet is based on the idea that limiting carbohydrates will cause the body to burn fat instead of sugar for fuel, contributing to higher and more consistent energy levels throughout the day and aiding weight loss and weight maintenance.
The Atkins diet consists of four phases, with the first phase being the most well-known and often mistaken for the whole program. This initial phase involves reducing carb consumption to under 20 grams per day for 2 weeks, with the goal of kick-starting the body's fat-burning metabolism. During this phase, individuals are advised to eat high-fat, high-protein foods and low-carb vegetables. The second phase involves slowly adding more nuts, low-carb vegetables, and small amounts of fruit back into the diet. The third phase is about fine-tuning, as individuals add more carbs to their diet until weight loss slows down. The fourth and final phase is about maintenance, where individuals find their personal carb balance to continue losing weight, control their appetite, and stay energised.
The Atkins diet can be effective for weight loss, as numerous studies have shown that low-carb diets can lead to weight loss without the need for calorie counting. For example, a 2020 study on older adults living with obesity found that participants who followed a very low-carb diet like Atkins did lose some belly fat. However, it is important to note that more research is needed to understand the effectiveness of this diet across different age groups and health states. Additionally, individuals with kidney disease and pregnant women should not follow the Atkins diet.
The Atkins diet may also have some side effects, such as an increased risk of not getting enough fibre, which is important for protecting against heart disease and certain types of cancer, regulating appetite, and supporting gut health. Furthermore, the high saturated fat content of the Atkins diet may raise LDL (bad) cholesterol in some individuals, potentially increasing the risk of heart disease. Therefore, it is always recommended to consult a doctor or registered dietitian before starting any new weight-loss diet to ensure it aligns with individual health needs.

Dairy products allowed on Atkins
The Atkins diet is a low-carbohydrate diet, usually recommended for weight loss. It was created by Dr Robert C. Atkins, who wrote a best-selling book about it in 1972. The diet has evolved since its creation and there are now two versions: Atkins 20 (the original diet, based on an intake of 20 grams of net carbs per day) and the newer Atkins 40, which is less strict and based on an intake of 40 grams of net carbs per day.
The Atkins diet is typically high in fat and protein, with meals based around meat, fatty fish, and dairy. The diet recommends eating full-fat dairy products such as butter, cheese, cream, and full-fat yogurt. Lacto-ovo-vegetarians can also eat eggs, butter, heavy cream, and other high-fat dairy foods.
The diet is divided into phases, with the first phase being the most strict. During this initial phase, followers of the diet are advised to limit their daily net carb intake to an average of 20 grams. This is to kickstart their fat-burning metabolism. As the dieter progresses through the phases, they can slowly add more carbs to their diet.
It is important to note that while the Atkins diet can be effective for weight loss, it has been criticised for its high saturated fat content. Experts caution that a diet high in saturated fats can increase the risk of heart disease and cancer. Therefore, it is always recommended to consult a healthcare professional before starting any new diet, especially one that restricts certain food groups.

Phases of the Atkins diet
The Atkins diet is a low-carbohydrate diet designed to help people lose weight and improve their health. There are four phases to the Atkins diet: induction, balancing, fine-tuning, and maintenance. The diet is designed to be flexible and tailored to individual needs and goals.
Phase 1, Induction, is designed to kickstart weight loss. During this phase, people are recommended to consume under 20 grams of net carbohydrates per day for two weeks, although some people may choose to stay in this phase for longer. The focus is on eating low-carbohydrate vegetables, such as leafy greens, asparagus, broccoli, celery, cucumber, green beans, and peppers. It is important to note that side effects such as headaches, dizziness, and fatigue may occur during this phase due to the drastic reduction in carbohydrates.
In Phase 2, Balancing, people can slowly add back nuts, seeds, and nutrient-rich carbohydrates such as vegetables and berries while continuing to consume 12-15 grams of daily net carbs from low-carbohydrate sources.
Phase 3, Fine-Tuning, begins when an individual is close to their goal weight, about 10-15 pounds away. During this phase, people continue to increase the variety of foods in their diet and may add 10 grams of carbohydrates each week. However, if weight loss stops, it is recommended to cut back on the amount of food consumed.
Phase 4, Maintenance, is the final phase of the Atkins diet. In this phase, individuals can eat as many healthy carbohydrates as their body can tolerate without regaining weight. The idea is to continue this way of eating for life, focusing on predominantly low-carbohydrate choices. By this phase, individuals should have a good understanding of their personal carb balance and how many carbohydrates they can consume while maintaining their weight.
The Atkins diet has evolved since its creation in 1972, and there are now three different plans: Atkins 20, Atkins 40, and Atkins 100, which vary in the strictness of carbohydrate restriction. It is important to note that the Atkins diet goes against dietary guidelines recommended by many health organizations and medical professionals, and there is a lack of strong evidence for its long-term success and safety.

Health benefits and risks of Atkins
The Atkins diet is a low-carbohydrate, high-protein, and high-fat diet. It was created in the 1960s by cardiologist Dr. Robert C. Atkins, who wrote a best-selling book about it in 1972. The diet involves eating foods such as meat, fatty fish, eggs, and dairy, while limiting or avoiding carbohydrates like sugar, refined grains, fruit, and starchy vegetables.
Health Benefits
The Atkins diet has been associated with several potential health benefits, including:
- Weight loss: The Atkins diet can lead to rapid weight loss, which can help reduce risk factors for high blood pressure, heart disease, and diabetes.
- Improved cholesterol: Some studies have shown that the Atkins diet can lead to improved HDL ("good") cholesterol and lowered LDL ("bad") cholesterol.
- Balanced blood sugar: The Atkins diet can help regulate blood sugar levels, which is especially beneficial for people with diabetes or prediabetes.
Health Risks
However, there are also some potential health risks associated with the Atkins diet:
- Increased risk of certain diseases: Some experts warn that a diet high in fat and protein from animal sources can increase the risk of heart disease and certain types of cancer, especially colon cancer.
- Ketoacidosis: Low-carbohydrate diets can lead to a state called ketoacidosis, which is similar to the state that occurs in diabetes.
- Short-term side effects: Adopting the Atkins diet can cause side effects like headaches, dizziness, weakness, fatigue, and "keto flu," especially in the initial phase.
- Social impact: Cutting out certain food groups can make it difficult to attend social events or eat out at restaurants.
- Lack of long-term studies: While the Atkins diet has been shown to be effective for short-term weight loss, there is a lack of large-scale, long-term studies on its health benefits and risks.

Vegetarian and vegan Atkins options
The Atkins diet is a low-carbohydrate diet, usually recommended for weight loss. It is traditionally focused on eating lots of meat, especially in the initial "induction phase". However, with some adjustments, it can be adapted for vegetarians and vegans.
Vegetarians can get their protein from eggs, legumes, nuts, dairy, and soy products. They can also eat cheese, butter, heavy cream, and other high-fat dairy foods. For vegans, protein can come from seeds, nuts, soy products, soy and rice cheeses, seitan, legumes, and high-protein grains like quinoa. Tofu, tempeh, seitan, and edamame are good options for both vegans and vegetarians.
The Atkins 40 plan is a newer, more flexible option, allowing 40 g of net carbs daily, increasing by 10 g per week once within 10 pounds of your weight goal. Atkins 20, the traditional plan, is more restrictive, especially in the induction phase, where net carb intake is limited to an average of 20 grams per day. For this reason, it is recommended that vegetarians and vegans start with Phase 2 of Atkins 20, which permits more carbs. In this phase, vegans can start with 50 g of net carbs per day, following the same weekly, bi-weekly, or monthly increments as the standard plan until they reach 80 g.
Some meal ideas for vegetarians and vegans on the Atkins diet include:
- Breakfast: Eggs, Chia Pecan Overnight Oats, or a Vegan Garden Vegetable Frittata
- Lunch: Vegan Chickpea Penne Salad or Vegetarian Ramen Zoodle Bowls
- Dinner: Vegan Chipotle Chili or Mediterranean Grilled Tofu
