The Atkins diet is a weight-loss plan created by cardiologist Robert Atkins. It involves eating mostly fat and protein while restricting carbohydrates, with the goal of burning body fat instead of carbs for energy. The diet has been popular worldwide since the release of Dr Atkins' book in 1972, and there are now several versions of the plan available, including Atkins 20, Atkins 40 and Atkins 100. Each version of the diet involves four phases, with the first phase being the most restrictive and designed to kick-start weight loss. During this initial phase, dieters are limited to under 20 grams of net carbohydrates per day, with the option to accompany a carb snack with either fat or protein. In the following phases, more foods are gradually reintroduced, with the overall goal of finding the maximum number of net carbs that can be consumed while still losing weight.

What You'll Learn
Atkins 20 and Atkins 40
The Atkins Diet is a low-carb diet, usually recommended for weight loss. It was introduced by Dr Robert C. Atkins, who wrote a best-selling book about it in 1972. Atkins 20 and Atkins 40 are two of the three low-carb diet plans offered by Atkins.
Atkins 20
Atkins 20 is the first phase of the Atkins diet and is designed to jumpstart your weight loss. It involves reducing your daily net carb intake to an average of 20 grams a day. Of these, 12-15 grams should be in the form of foundation vegetables. The length of the induction phase depends on your weight loss goals. For some, Phase 1 may only last two weeks. However, you may follow it for longer if you have a lot of weight to lose or prefer to lose weight quickly.
Atkins 40
Atkins 40 is a low-carb diet plan based on portion control and eating 40 grams of net carbs per day. It is perfect for those who have less than 40 pounds to lose. It offers a flexible and extensive food list, including protein, veggies, pasta, and potatoes. It is also suitable for vegetarians and vegans. On Atkins 40, you can enjoy a range of foods while still losing weight and feeling satisfied. As you approach your weight loss goals, you can increase your carbohydrate portion size.
General Tips for the Atkins Diet
It is important to consult your doctor or a registered dietitian before starting the Atkins diet, especially if you have diabetes, kidney disease, or are pregnant. Additionally, people with high cholesterol or an increased risk of heart disease should monitor their cholesterol levels while on the diet.

What to eat and avoid
The Atkins diet is a low-carb diet, usually recommended for weight loss. It involves counting and limiting carbs so that the body is forced to burn fat stores for energy. The Atkins diet is divided into four phases: Induction, Balancing, Fine-tuning, and Maintenance.
During the Induction phase, you should consume under 20 grams of carbs per day for two weeks, focusing on high-fat, high-protein foods, and low-carb vegetables. This phase is designed to jumpstart your weight loss. In the Balancing phase, you can slowly add more nuts, low-carb vegetables, and small amounts of fruit back to your diet.
In the Fine-tuning phase, as you get closer to your goal weight, you can add more carbs to your diet until your weight loss slows down. Finally, in the Maintenance phase, you can eat as many healthy carbs as your body can tolerate without regaining weight.
The Atkins diet allows you to eat bacon, cream cheese, and steak. It recommends choosing three servings of healthy fats per day, such as olive oil, and getting protein from sources like soy and lentils. It is important to note that the Atkins diet may not include enough fiber, and it may cause dehydration, so it is important to consult a doctor or dietitian before starting this or any other diet.
During the Induction phase, focus on consuming under 20 grams of carbs per day, primarily from low-carb vegetables like leafy greens. Enjoy high-fat, high-protein foods, such as olive oil, soy, lentils, and unprocessed, naturally occurring fats. Avoid starchy, sugary carbs, including white bread, pasta, white potatoes, grains, milk, yogurt, and fruit.
In the Balancing phase, slowly introduce more nuts, seeds, and berries, as well as small amounts of fruit. Continue to avoid starchy and sugary carbs, but you may start to include some whole grains and dairy.
As you approach your goal weight in the Fine-tuning phase, gradually add more carbs to your diet, such as whole grains and fruits. Monitor your weight loss, and if it slows down, adjust your carb intake accordingly.
Finally, in the Maintenance phase, you can enjoy a wider variety of foods, including healthy carbs that your body can tolerate without weight gain. However, it is important to continue avoiding highly processed and sugary carbs, and focus on whole, unprocessed options.

Health benefits and risks
The Atkins diet is a low-carbohydrate, high-protein, and high-fat diet. It was first introduced to American markets in the 1960s and was initially considered unhealthy due to its high saturated fat content. The diet has four phases: induction, balancing, fine-tuning, and maintenance. In the induction phase, carbohydrate consumption is restricted to under 20 grams per day for two weeks to kickstart weight loss. In the balancing phase, more nuts, low-carb vegetables, and small amounts of fruit are slowly added back to the diet. Fine-tuning involves adding more carbohydrates until weight loss slows down. In the maintenance phase, individuals can eat as many healthy carbohydrates as their body can tolerate without regaining weight.
The Atkins diet has been associated with several health benefits and risks.
Health Benefits
The Atkins diet is popular due to its weight loss benefits and the freedom it offers to consume as much protein and fat as desired. The diet has been shown to lower cholesterol and improve both LDL "bad" cholesterol and HDL "good" cholesterol. A 2020 study on older adults living with obesity found that participants who followed a very low-carb diet like Atkins lost some belly fat.
Health Risks
The Atkins diet has been criticised for greatly increasing fat and protein consumption, which can lead to serious health issues. The high protein and fat content can lead to hyperuricemia, resulting in joint pain and gout, and hypercalcuria, causing kidney stones, hypocalcemia, and osteoporosis. The diet's restriction of carbohydrates can also reduce the intake of essential nutrients, minerals, trace elements, vitamins, and fibre, which promote overall health and prevent diseases. The increased oxidative stress and reduced fibre intake associated with low-carbohydrate diets may increase the risk of cancer, particularly in the lungs and gastrointestinal tract.
Additionally, individuals with certain health conditions should exercise caution. People with high cholesterol or an increased risk of heart disease should monitor their cholesterol while on the diet, as long-term risks include the possibility of increased LDL "bad" cholesterol. The diet is not recommended for individuals with kidney disease, diabetes, or pregnant women. The high consumption of red meat associated with the diet may increase the risk of colon cancer and put additional stress on the kidneys.
While the Atkins diet may offer initial weight loss benefits, it is important to consult a doctor or registered dietitian before starting this or any other weight-loss diet to ensure it aligns with individual health needs and does not pose unnecessary health risks.

Atkins vs keto
The Atkins and keto diets are two of the most well-known low-carb diets. They are similar in that they both drastically reduce high-carb foods, including sweets, sugary drinks, breads, grains, fruits, legumes, and potatoes. However, there are some key differences between the two diets.
The Atkins diet is a low-carb, moderate-protein, and high-fat diet. It is typically divided into four phases, with the daily allowance of net carbs increasing in each phase. Phase 1, also known as the induction phase, allows for 20-25 grams of net carbs per day. This phase focuses on reducing carb consumption to kick-start fat burning. People stay in this phase until they are 15 pounds away from their ideal weight. Phase 2, or the balancing phase, involves slowly adding more nuts, low-carb vegetables, and small amounts of fruit back into the diet. Carb intake during this phase is typically 25-50 grams per day. Phase 3, or the fine-tuning phase, allows for up to 80 grams of carbs per day until the individual reaches their goal weight. Finally, Phase 4, or the maintenance phase, has no set limit on carb intake, but individuals can eat as many healthy carbs as their body can tolerate without regaining weight.
The keto, or ketogenic, diet, on the other hand, is a very low-carb, moderate-protein, and high-fat diet. The main goal of the keto diet is to get the body into a state of ketosis, where it uses fat instead of sugar from carbs as its main energy source. To reach and maintain ketosis, most people need to limit their total carb intake to 20-50 grams per day, with less than 5% of their total calories coming from carbs. The keto diet was originally developed to treat children with seizures or epilepsy, but it has since been found to have potential benefits for other individuals as well.
One of the main differences between the Atkins and keto diets is the approach to carb intake. While the Atkins diet gradually increases carb consumption over time, the keto diet emphasises keeping carb intake extremely low to maintain ketosis. This means that the Atkins diet is generally less restrictive and allows for a wider variety of foods, including more fruits, vegetables, and even some grains. Additionally, the Atkins diet allows for up to 30% of calories from protein, while the keto diet typically has about 20% of calories coming from protein.
It is important to note that both diets may have potential health risks and restrictions. Individuals with certain health conditions, such as high cholesterol, an increased risk of heart disease, kidney disease, or diabetes, should consult a doctor or registered dietitian before starting either diet. Additionally, pregnant individuals should not follow the Atkins diet.

Atkins diet maintenance
The Atkins diet is a low-carb, high-protein, and high-fat diet, usually recommended for weight loss. It was created by Dr. Robert Atkins, an American cardiologist, in the early 1970s. The diet has four phases: Induction, Balancing, Fine-tuning, and Maintenance.
The Atkins diet maintenance phase is the fourth and final phase of the diet. By this stage, you should be close to your goal weight. During maintenance, you can eat as many healthy carbs as your body can tolerate without regaining weight. This phase is about finding a balance between enjoying the foods you like and maintaining your weight loss results.
During maintenance, you can continue to eat the foods you were eating in the previous phases, such as:
- Meats: beef, pork, lamb, chicken, bacon, etc.
- Fatty fish and seafood: salmon, trout, sardines, mackerel, etc.
- Eggs: omega-3 enriched or pastured.
- Low-carb vegetables: leafy greens, kale, spinach, broccoli, asparagus, etc.
- Full-fat dairy: butter, cheese, cream, full-fat yogurt.
- Nuts and seeds.
- Atkins products: shakes, snacks, etc.
Additionally, you can slowly reintroduce some higher-carb foods that were restricted in the earlier phases, such as:
- Fruits: apples, bananas, oranges, grapes, etc.
- Starchy vegetables: potatoes, sweet potatoes.
- Legumes: lentils, beans, chickpeas, etc.
It is important to monitor your weight and overall health during the maintenance phase. If you find that you are regaining weight, you may need to reduce your carb intake or return to a previous phase.
Remember, it is always a good idea to consult your doctor or a registered dietitian before starting or maintaining a weight-loss diet plan, especially if you have any health concerns or conditions.

Frequently asked questions
The Atkins diet is an eating plan created by cardiologist Robert Atkins. It involves restricting carbs while eating mostly fat and protein. The idea is to burn body fat instead of carbs for energy, resulting in a shift in your metabolism.
The Atkins diet comes in three versions: Atkins 20, Atkins 40, and Atkins 100. Each version involves four phases, and the goal is to lose weight by reducing carbs. In the initial phase, you restrict your carb intake to under 20 grams per day for Atkins 20, and 40 grams per day for Atkins 40. As you progress through the phases, you gradually add more carbs until you reach a level where you can maintain your weight.
The Atkins diet focuses on eating protein and healthy fats, with a limited number of carbs coming from vegetables and some dairy, nuts, and seeds. You can eat foods like bacon, eggs, smoked salmon, cream cheese, and steak. It's important to note that you should avoid processed and packaged foods, as well as limit your salt intake.
Research has found that low-carb diets may increase levels of LDL ("bad") cholesterol. Additionally, the Atkins diet was initially considered unhealthy due to its high saturated fat content. While there is ongoing debate about the impact of saturated fat on health, some suggest replacing saturated fat with polyunsaturated fat to reduce the risk of cardiovascular disease. It is always recommended to consult a healthcare professional before starting any new diet.
