The Atkins diet is a low-carbohydrate, high-protein, and high-fat diet, usually recommended for weight loss. It involves four phases, with the first being the strictest, limiting daily net carbs to 20 grams, and the last phase allowing up to 100 grams of net carbs per day. A typical meal on the Atkins diet is high in fat and protein, with low-carb vegetables. This could include a meal of fatty meat or fatty fish with a side of leafy greens or other non-starchy vegetables, like courgettes and cucumbers.

What to eat and what to avoid
The Atkins diet is a low-carbohydrate diet, usually recommended for weight loss. The Atkins diet comes in three versions: Atkins 20, Atkins 40, and Atkins 100. Each involves four phases, and the goal is to lose weight by reducing carbs.
What to eat
In the first phase, you must eat only 20 grams of net carbs daily, which come from vegetables. You can eat high-fat, high-protein foods with low-carb vegetables, such as leafy greens, courgette, cucumber, avocado, and olives. You can also eat red meat, butter, cream, and cheese. About 43% of what you eat should come from healthy plant-based fat sources such as avocado, nuts, seeds, olive oil, and coconut oil. About 31% of your food should be protein from plant-based sources like soy or beans. Lacto-ovo-vegetarians can also eat eggs, cheese, butter, heavy cream, and other high-fat dairy foods.
In the second phase, you slowly add some whole-food carbohydrates back to your diet, eating between 25 and 50 net carbs daily.
In the third phase, you continue to add a variety of carbohydrates to your diet, including more whole grains.
In the fourth phase, once you reach your ideal weight, you continue to eat a predominantly low-carbohydrate diet (80-100 net carbs per day) for life.
What to avoid
The typical foods to be avoided include starchy vegetables like corn and potatoes; fruits with a high sugar content such as pineapple, mango, and banana; baked goods such as biscuits and cakes; refined carbs such as white bread, pasta, and rice; and sugary drinks. You should also avoid adding condiments to your meals, as ketchup, honey mustard, and barbecue sauce are high in carbs. Alcohol should be limited to small amounts, and dry wines with no added sugars are preferred over high-carb drinks like beer and cocktails.

Alcohol
The Atkins diet is a low-carb, high-fat, and high-protein diet. Alcoholic drinks often contain carbohydrates, with beer and sweet alcoholic drinks containing the most carbs. Spirits like vodka, gin, rum, and tequila contain zero carbs when consumed neat or on the rocks. Wine, both red and white, contains a moderate amount of carbs and can be enjoyed in moderation during the later phases of the diet.
It is important to consider the caloric content of alcoholic beverages when following the Atkins diet. Alcohol is calorically dense, with 7 calories per gram, compared to 4 calories per gram for carbohydrates and proteins. Many alcoholic drinks also contain additional calories in the form of sugars and other additives.
If you choose to consume alcohol while on the Atkins diet, it is recommended to prioritise low-carb and low-calorie options. Distilled spirits like whisky, vodka, and gin have fewer or no carbs, but watch out for high-calorie mixers. An occasional glass of wine is also acceptable, as long as you count the carbohydrates in your daily tally. However, it is important to be mindful of your health goals and not let alcohol derail your progress.

Eating out
Firstly, consider the type of cuisine and choose a restaurant that serves more protein-based dishes. An American or steakhouse restaurant might be a better choice than an Italian or Asian restaurant, where pasta, rice, and noodles are staple foods. Scrutinise the menu online before you arrive, so you can plan your order and not be tempted by dishes that do not fit your diet.
When ordering, ask the waiter about the carb content of the dishes and be cautious of hidden carbs and sugars. Avoid starchy sides like bread, potatoes, and rice, and opt for extra vegetables or a side salad instead. Choose a meal based on fatty meat or fatty fish, and don't be afraid to ask for some extra sauce, butter, or olive oil to increase your fat intake.
If you are on a plant-based Atkins diet, you will need to be extra vigilant about your choices. Substitute meat and fish with plant-based proteins like soy or beans, and ensure you are getting enough healthy plant-based fats like avocado, nuts, and seeds.
Remember, the Atkins diet can be restrictive, and it is important to be mindful of potential side effects and nutrient deficiencies. It is always a good idea to consult a healthcare professional before starting any new diet, especially one as specific as Atkins.

Pros and cons
The Atkins diet is a low-carbohydrate diet, usually recommended for weight loss. It involves eating high-fat sources of protein, such as meat, fatty fish, and dairy, while limiting carbohydrates. The diet is divided into three versions: Atkins 20, Atkins 40, and Atkins 100, each with four phases that gradually increase the variety of foods allowed.
Pros
The Atkins diet has been around since the 1970s and has been the subject of numerous studies documenting its benefits. Some of the potential advantages include:
- Weight loss: The diet is effective for weight loss, with many people experiencing positive results in the first few weeks.
- Health improvements: Lowering carbohydrate intake can lead to improvements in certain health conditions, such as diabetes, high blood pressure, and heart disease.
- Simplicity and ease: The diet is relatively simple to follow, as it focuses on a few food groups, and there is no need for calorie counting or measuring portions.
- Flexibility: The Atkins diet offers flexibility, as it can be adapted for vegetarians and vegans by substituting meat with plant-based sources of protein and healthy fats.
- Improved food choices: The diet encourages eliminating processed foods and replacing them with whole foods like leafy greens and healthy fats, which can have a positive impact on overall health.
Cons
However, there are also some potential disadvantages and challenges to consider:
- Weight regain: Research shows that weight lost on the Atkins diet, like with most diets, is often regained.
- Increased risk of certain diseases: Consuming too much animal fat can raise the chances of developing heart disease and cancer.
- Side effects: Reducing carbohydrate intake can lead to side effects like fatigue, nausea, headaches, and brain fog, commonly known as the "keto flu."
- Restrictive nature: The diet prohibits fruits and grains in the initial phase, which may be challenging for those who enjoy these foods. Additionally, it can be difficult to stick to the plan, as even a small number of extra carbohydrates can be considered cheating.
- Nutritional concerns: Fruits and whole grains provide important vitamins, nutrients, and fiber, and their absence in the diet can lead to constipation.
- Social challenges: Dining out or social situations involving food may become more complicated, as special requests or menu modifications may be necessary.

Atkins diet phases
The Atkins diet consists of several phases, each with specific guidelines and goals. Here is a detailed breakdown of the four phases:
Phase 1: Induction
This is the most restrictive phase of the Atkins diet, designed to kickstart weight loss and change the body's metabolism. During this phase, individuals restrict their net carb intake to around 20 grams per day, a significant departure from the FDA recommendation of 275 grams. This shift aims to force the body to burn fat for energy instead of glucose, a process known as ketosis. The length of Phase 1 depends on individual weight loss goals, and it may last from two weeks to several months. It is important to note that some people choose to stay in this phase indefinitely, which is known as a very low-carb ketogenic diet or keto.
Phase 2: Balancing the Diet
In this phase, individuals slowly reintroduce whole food carbohydrates while continuing to lose weight. The daily net carb intake increases to between 25 and 50 grams. This phase continues until the individual is within 5 to 10 pounds of their desired weight. The main goal of Phase 2 is to determine the number of carbs one can consume while still losing weight.
Phase 3: Individualizing and Optimizing the Diet
During this phase, individuals continue to add a wider variety of carbohydrate sources to their diet while carefully monitoring their weight. Net carb intake can vary between 40 and 120 grams per day. This phase is about finding a personalized approach to carbohydrate consumption that aligns with individual weight loss and maintenance goals.
Phase 4: Lifetime Maintenance
Once the desired weight is achieved, individuals enter the maintenance phase, adopting a predominantly low-carbohydrate diet for life. By this stage, individuals should have a good understanding of their personal carb balance, allowing them to maintain their weight. This final phase emphasizes the importance of making long-term dietary changes to sustain the benefits achieved during the previous phases.
