The Atkins diet is a low-carbohydrate diet for weight loss that consists of four phases. Phase 1, also known as the induction phase, is the strictest part of the diet and is designed to jump-start weight loss. During this phase, individuals must restrict their net carb intake to 20 grams per day, which is significantly lower than the FDA recommendation of 275 grams. The length of the induction phase can vary depending on one's weight loss goals, but it typically lasts for about two weeks. During this time, it is recommended to consume high-fat and high-protein foods, along with low-carb vegetables like leafy greens. It is important to note that the Atkins diet may lead to side effects such as an increased risk of heart disease and certain types of cancer due to the high saturated fat content. Consulting a registered dietitian or physician before starting this diet is advisable.

What You'll Learn
The induction phase restricts net carbs to 20 grams daily
The induction phase, or Phase 1, of the Atkins diet is all about jumpstarting your weight loss journey by changing the way your body uses nutrients. The idea is to shift your body from burning primarily carbs to burning primarily fat. During this phase, you will be reducing your daily net carb intake to an average of 20 grams, with an acceptable range of 18 to 22 grams. This shift in carbohydrate intake will help your body enter a state of ketosis, where it begins to burn fat as its primary energy source.
To achieve this, it is crucial to stick to the list of acceptable foods for Phase 1. This includes a variety of low-carb foundation vegetables, proteins, healthy fats, and most cheeses. Of the 20 grams of net carbs allowed, 12 to 15 grams should come from foundation vegetables. You can also include dairy, dressings, or Atkins products, which contribute an additional 5 to 8 grams of net carbs. It is important to note that you should not go below 18 grams or above 22 grams of net carbs in a single day.
During the induction phase, it is recommended to consume three 4-6 ounce servings of protein each day. This can include poultry, fish, shellfish, eggs, and red meat. Protein plays a key role in weight loss and helps protect lean muscle mass, ensuring that you lose primarily fat. Additionally, consuming fat is essential in this phase. Fat enhances the flavour of foods and enables your body to absorb certain vitamins. Always accompany a carb snack with either fat or protein. For example, you can have cucumber slices with a piece of cheese.
The length of the induction phase depends on your weight loss goals. For some, Phase 1 may only last two weeks. However, if you have a significant amount of weight to lose or prefer to lose weight quickly, you can safely follow this phase for a more extended period. You will continue with Phase 1 until you are 15 pounds away from your goal weight. It is important to note that this phase should not be rushed and that individual results may vary.

Eat high-fat, high-protein foods with low-carb vegetables
Phase 1 of the Atkins diet is about changing the way your body uses nutrients and kick-starting weight loss. It involves eating under 20 grams of carbohydrates per day for two weeks, focusing on high-fat, high-protein foods, and low-carb vegetables. The length of this phase depends on your weight loss goals.
For your high-fat, high-protein, and low-carb vegetable intake, you can eat meats like beef, pork, lamb, chicken, and bacon. You can also eat fatty fish and seafood such as salmon, trout, sardines, and mackerel. Eggs are another good source of protein, especially omega-3 enriched or pastured eggs.
Low-carb vegetables that you can include are kale, spinach, broccoli, and asparagus. You can also eat full-fat dairy products like butter, cheese, cream, and full-fat yogurt. Nuts and seeds are another good source of healthy fats, with almonds, macadamia nuts, walnuts, and sunflower seeds being good options. Avocados and healthy oils like extra virgin olive oil and coconut oil are also recommended.
It is important to remember that you should not go hungry for more than three or four hours without eating. You can have five or six small meals a day, ensuring you get three 4-6 ounce servings of protein. When eating a carb snack, always accompany it with either fat or protein. For example, have cucumber slices with a piece of cheese.

Avoid sugar, refined grains, and high-carb fruits
The Atkins diet is a low-carb diet that involves restricting certain nutrients and focusing on high-fat, high-protein foods. Phase 1 of the Atkins diet, also known as the induction phase, is crucial for kick-starting weight loss and typically lasts for two weeks. During this phase, it is recommended to keep your daily carb intake under 20 grams, with 12-15 grams coming from foundation vegetables.
To avoid sugar, refined grains, and high-carb fruits during Phase 1, follow these guidelines:
- Sugar Avoidance: Sugar is prevalent in soft drinks, fruit juices, cakes, candy, and ice cream. Even "diet" and "low-fat" foods can be high in sugar. Read labels carefully and avoid added sugars as much as possible. Be mindful that some processed meats, like bacon and ham, are cured with sugar, so opt for fresh cuts instead.
- Refined Grains Elimination: Refined grains, such as white bread, white rice, and white pasta, are off-limits during Phase 1. Instead, opt for whole grains like brown rice, oatmeal, bulgur, quinoa, and teff in moderation, ensuring they fit within your daily carb goal.
- High-Carb Fruit Restriction: Fruits like bananas, apples, oranges, pears, and grapes are considered high in carbs and should be avoided during the induction phase. Focus on low-carb vegetables like leafy greens (spinach), kale, broccoli, and asparagus instead.
- Meal Planning: Plan your meals to ensure you don't go hungry. Eating small, frequent meals that include protein and healthy fats can help you feel satiated and avoid cravings for sugary or high-carb foods.
- Snacking: Choose low-carb snacks to have between meals. Options like cucumber slices with cheese or an Atkins Endulge bar can help you stay on track and avoid reaching for sugary snacks.
- Drink Choices: Water should be your primary beverage. Coffee and green tea are also acceptable, as they are high in antioxidants. Avoid sugary drinks, including fruit juices and soft drinks. If you consume alcohol, stick to dry wines without added sugars, and avoid high-carb drinks like beer and cocktails.

Consume three 4-6 ounce servings of protein daily
Atkins 20 Phase 1, also known as the Induction phase, is all about changing the way your body uses nutrients to kickstart your weight loss journey. The Atkins diet recommends consuming two to three 4-6 ounce servings of protein daily. This is higher than the RDA recommendation of 0.36 grams of protein per pound of body weight for adults. However, it's important to note that the RDA reflects the minimum requirement, while Atkins focuses on optimal protein intake.
Protein plays a crucial role in weight loss and preserving lean muscle mass, ensuring that you lose only fat. It helps stabilize your blood sugar levels, reducing cravings for sweets or salty snacks. Additionally, protein boosts your metabolic rate, and studies have shown that a high-protein diet leads to greater body-fat loss compared to a high-carb diet.
When including protein in your meals, aim for a serving size of 4-6 ounces, which is approximately 120-180 grams of uncooked protein. This can be in the form of grilled salmon, chicken breasts, boiled eggs, or pork belly. You can also have protein-rich snacks, such as a Spicy Boiled Egg and Salad, or use protein bars and shakes as a convenient way to increase your protein intake.
It's important to remember that the ideal amount of protein should leave you feeling satisfied after a meal but not overly stuffed, and you should still feel hungry in time for your next meal. Adjust your protein intake according to factors like age, gender, activity level, and body composition.

The phase lasts two weeks, with the option to extend
The first phase of the Atkins diet is the induction phase, which is designed to jump-start your weight loss. It is the strictest part of the diet and typically lasts for two weeks, but you can choose to extend it. During this phase, you are instructed to eat under 20 grams of carbohydrates per day. This is significantly less than the FDA recommendation of 275 grams of carbohydrates daily.
The Atkins diet is a low-carbohydrate diet, which means that during the induction phase, you will be cutting back on carb consumption. You will be eating high-fat, high-protein foods, with low-carb vegetables like leafy greens. It is recommended to have five or six small meals a day so that you never get too hungry. You should also be consuming three 4-6 ounce servings of protein per day.
The induction phase is designed to change your metabolism so that your body burns fat for energy instead of glucose, a process called ketosis. As you reduce your carb intake, your body will be prompted to use fat for fuel, resulting in weight loss from this fat-burning metabolism.
You can extend the induction phase beyond the initial two weeks if you have a lot of weight to lose or prefer to lose weight quickly. You can stay in this phase until you are 15 pounds away from your goal weight. However, it is important to consult a registered dietitian or physician before starting a new weight-loss diet plan, especially one that restricts certain nutrients that are important for your body.
