The Atkins diet is a popular weight-loss plan based on eating fewer carbohydrates and more fatty foods. It was developed by Dr Robert Atkins, an American cardiologist, who argued that a low-carbohydrate diet produces a metabolic advantage because burning fat takes more calories so you expend more calories. The diet involves four phases, starting with an induction phase where the body switches from burning carbs to fat, which is called ketosis. During this phase, people on the diet eat protein, fat, and only 20 grams of carbs in vegetable form daily. The Atkins diet has been criticised by some as nutritionally unbalanced and for its high saturated fat content, which may increase the risk of heart disease. However, it has been shown to be effective for weight loss and can lead to various health improvements.

What You'll Learn
The Atkins diet is a low-carb, high-fat, high-protein diet
The Atkins diet is a low-carbohydrate, high-fat, high-protein diet, usually recommended for weight loss. The diet was created by Dr Robert Atkins, an American cardiologist, who wrote a best-selling book about it in 1972. The Atkins diet is based on the idea that restricting carbohydrates is the key to weight loss. The diet involves eating large amounts of protein and fat while limiting carbohydrates, primarily from vegetables.
The Atkins diet has four phases, beginning with an induction phase that lasts about two weeks. During this phase, individuals consume under 20 grams of carbohydrates per day and focus on eating high-fat, high-protein foods with low-carb vegetables like leafy greens. The goal of this phase is to help the body switch from burning carbohydrates to burning fat, a process called ketosis.
In the second phase, individuals start adding foods back into their diet, gradually increasing their carbohydrate intake while still focusing on weight loss. The third phase is about maintaining weight loss and losing the last few pounds. Finally, the fourth phase is a lifelong commitment to ensuring that the lost weight is not regained.
The Atkins diet has been criticised by some experts and organisations, including the American Medical Association, the American Dietetic Association, and the American Heart Association, as being nutritionally unbalanced and potentially increasing the risk of heart disease due to its high saturated fat content. However, proponents of the diet argue that it can lead to weight loss and improve various health markers such as blood sugar and cholesterol levels.

It is usually recommended for weight loss
The Atkins diet is a low-carb diet, usually recommended for weight loss. It was initially considered unhealthy, mainly due to its high saturated fat content. However, since the early 2000s, several studies have shown that low-carb diets are effective for weight loss and can lead to other health improvements.
The Atkins diet plan involves four phases. In the first phase, the induction phase, individuals consume under 20 grams of carbs per day for two weeks. This phase includes high-fat, high-protein, and low-carb vegetables. The second phase, or balancing phase, involves slowly adding more nuts, low-carb vegetables, and small amounts of fruit to your diet. In the third phase, or fine-tuning phase, those following the diet add more carbs until weight loss slows down. Finally, in the fourth phase, or maintenance phase, individuals can eat as many healthy carbs as their body can tolerate without regaining weight.
The Atkins diet can be an effective way to lose weight, but it may not be suitable for everyone. For example, it may be expensive to rely heavily on fresh produce and high-quality meat. Additionally, restrictive diets have been shown to increase the likelihood of some individuals developing disordered eating habits. It is always recommended to consult a doctor or dietitian before starting a new diet.
The Atkins diet has been promoted as a way to manage diabetes and improve heart health, in addition to weight loss. A 2020 study found that older adults with obesity who followed a very low-carb diet like Atkins lost some belly fat. However, more research is needed to understand the effects of this diet across different age groups and health states.

It has been criticised for being nutritionally unbalanced
The Atkins diet has been criticised by the American Medical Association, American Dietetic Association and the American Heart Association as nutritionally unbalanced. The diet is promoted with claims that carbohydrate restriction is the key to weight loss. Proponents of this diet claim that you can lose weight while eating as much protein and fat as you want if you avoid foods high in carbohydrates.
The Atkins diet is a very low-carb ketogenic diet. Individuals on this diet are told to avoid or limit sugar, refined grains, "diet" and "low-fat" foods, high-carb fruits, starchy vegetables, legumes, and more. The diet recommends eating meats, fatty fish and seafood, eggs, and low-carb vegetables.
The American Heart Association issued a warning against high-protein, high-fat, low-carbohydrate diets as a means of losing weight. The Atkins diet, in particular, has been found to contain very high levels of fat—60% to 68%, with around 26% of which are saturated fats. This high level of saturated fat can increase the risk of heart disease. The American Heart Association's review of saturated fat's impact on heart disease concluded that replacing saturated fat with polyunsaturated fat is beneficial.
The Atkins diet has also been criticised for its potential negative health effects. Research has found that low-carb diets may increase levels of LDL (bad) cholesterol. Additionally, the high protein content of a low-carbohydrate diet could lead to hyperuricemia, resulting in joint pain and gout, and hypercalcuria, which can cause kidney stones, hypocalcemia, and osteoporosis. A Harvard study showed that high-protein diets may cause permanent loss of kidney function in individuals with reduced kidney function. The American Diabetes Association has also cautioned against the use of low-carbohydrate diets, as carbohydrates from whole grains, fruits, vegetables, and low-fat milk are important for overall health.

It has four phases, beginning with an induction phase
The Atkins Diet is a low-carbohydrate, high-fat, high-protein diet, usually recommended for weight loss. It was developed by Dr Robert C. Atkins, who wrote a bestselling book about it in 1972. The diet has four phases: Induction, OWL, Pre-Maintenance, and Lifetime Maintenance.
Induction Phase
The first phase of the Atkins Diet involves eating under 20 grams of carbohydrates per day for two weeks. During this phase, individuals are instructed to eat high-fat, high-protein foods and low-carb vegetables like leafy greens. Some foods, such as carrots, apples, and legumes, are restricted during induction but can be reintroduced later.
OWL Phase
In the second phase, individuals slowly add more nuts, low-carb vegetables, and small amounts of fruit back to their diet. This phase continues until the individual is within 5-10 pounds of their target weight.
Pre-Maintenance Phase
In the third phase, individuals who are very close to their goal weight begin to add more carbohydrates to their diet until weight loss slows down. The aim is to find out how many carbohydrates an individual can eat while continuing to lose weight.
Lifetime Maintenance Phase
In the final phase, individuals can eat as many healthy carbohydrates as their body can tolerate without regaining weight. This phase is about maintaining health for life, not just losing weight. The average number of daily grams of Net Carbs in this phase ranges from 40 to 120 per day, depending on factors like metabolism, age, gender, and activity level.

It can be adapted for vegetarians and vegans
The Atkins diet is a low-carbohydrate, high-fat, high-protein diet, usually recommended for weight loss. It involves eating lots of meat, particularly in the initial "induction phase".
The traditional Atkins diet is not suitable for vegetarians or vegans, as it is centred on meat and animal products. However, with some adjustments, it can be adapted for those who follow a plant-based diet.
Eco-Atkins
The Eco-Atkins diet is a vegan Atkins alternative developed by researchers at St. Michael's Hospital in Toronto. It has a similar ratio of protein to carbs as the original Atkins diet, but replaces high-fat animal protein with vegetable protein. The diet is low in calories, providing 60% of the study participants' calorie requirements, and allows for exercise.
Atkins 20
The Atkins 20 is the name now used for the traditional Atkins plan. It is recommended that vegetarians and vegans start with Phase 2 of this plan, which is the "balancing" phase. Here, you slowly reintroduce certain carbs and foods to determine the proper balance for your body.
Atkins 40
Atkins 40 is a newer, more flexible version of the diet plan. It allows for a higher number of net carbs per day, which may make it easier for vegetarians and vegans to include nuts, beans, legumes, and whole grains in their meals.
Atkins 100
Atkins 100 is another option for vegetarians and vegans. It is recommended that vegans get sufficient protein from seeds, nuts, soy products, soy and rice cheeses, seitan, legumes, and high-protein grains like quinoa.
Tips for a low-carb vegetarian or vegan Atkins diet
- Stay hydrated by drinking eight glasses of water per day
- Choose lower-carb whole grains, such as long-grain brown rice and whole-grain pasta
- Embrace low-carb alternatives, such as almond flour or coconut flour instead of traditional flour, and zucchini noodles or spaghetti squash instead of pasta
- Plan and prepare meals in advance to make it easier to stick to the diet
- Find a community for support, such as the Atkins' community, where you can join like-minded groups
- Exercise regularly to boost your energy levels and help you feel balanced
