The New Atkins Diet pros and cons

We are going to review in detail the Atkins Diet its possible health consequences and the benefits it can provide us. Atkins is a plan to lose weight in a short time and without starving, favoring the consumption of meat and fat. Designed by Dr. Robert Atkins in the 70s, this weight loss plan became a book that quickly became a best-seller.

What is the Atkins Diet

However, for many nutritionists the Atkins Diet was not a balanced plan to lose weight since consuming large amounts of protein and fat could increase bad cholesterol (LDL) and triglycerides and therefore those who performed it increase the risk to suffer from coronary heart disease.

Thus, the Atkins Diet after several decades is renewed in some of its basic principles and therefore the current plan no longer restricts the consumption of certain foods so much and manages to maintain a better nutritional balance.

The New Atkins Diet

The renewal of the Atkins Diet seeks a better balance in the quantity, variety and quality of foods, however reducing the consumption of those that cause fat accumulation and create an acidic environment.

The principle of this diet is to limit the consumption of carbohydrate foods, also eliminating sugars and refined flours. However, this does not mean that the consumption of carbohydrates that cause fat is totally eliminated, what it does is limit the necessary consumption so that the metabolism can be accelerated and that the body can burn fat more quickly.

The goal of the Atkins Diet, beyond losing weight, is to learn to eat carbohydrates but also to give the body foods that provide more vitamins, antioxidants, and healthy phytochemicals.

The idea is that when the desired weight is reached whoever has followed the diet can determine the amount of carbohydrates that can be consumed daily without gaining weight, being able to enjoy a wide variety of meals, within a plan that is divided into phases where the The first is the strictest with a daily consumption of very few grams of carbohydrates.

After the first stage, the consumption of vegetables and fruits and other foods is increased to continue losing weight in a balanced and healthy way.

How to do the Atkins Diet

Like other weight loss diets, Atkins has a series of characteristics that must be taken into account, if you want to lose weight significantly in a short time, such as:

  • It cannot be followed for more than 30 days.
  • Sugars of any kind should be suppressed for several weeks and then gradually started to be incorporated.
  • It is possible to consume all kinds of meats and cheeses.
  • Carbohydrates are very limited.
  • There is a long list of forbidden foods.
  • After 15 days of starting the Atkins Diet, it becomes more flexible to include new foods.

The key to the Atkins Diet, according to its creator , lies in the metabolic changes that occur in the body because carbohydrates are responsible for providing much of the energy to the brain and muscles, when they are scarce the body responds by obtaining energy from stored fats.

As Atkins himself states in his book, when you stop eating bread or rice, the body begins to consume adipose tissue and fat deposits that accumulate in certain areas of the body are eliminated.

The Atkins Diet is developed in 4 phases and throughout the entire diet it is necessary to eat five meals a day: Breakfast, Mid-morning, Lunch, Snack and Dinner.

The most important thing is not to feel hungry, something that is totally possible since in this weight loss plan calories are not counted and therefore whenever you are hungry it is possible to eat.

Induction Phase

 The Induction Phase and has some basic rules that must be followed:

Induction Phase Rules

  1. Eat three normal meals a day and two smaller ones.
  2. Freely eat combinations of fat such as butter, mayonnaise, olive oil, vegetable oils and proteins such as poultry, fish, shellfish, red meat, eggs.
  3. Only consume 20 grams of carbohydrates daily in the form of green salads or other vegetables. These 20 grams are equivalent to 3 cups.
  4. Do not eat fruits, bread, pasta, grains, nuts, or seeds, starchy vegetables or dairy products with the exception of cheese, cream and butter.
  5. Do not eat foods that combine carbohydrates and proteins such as lentils, peas and other legumes that are not allowed in this first stage.
  6. Do not eat forbidden foods.
  7. You adjust the amounts of each meal to satisfy your appetite and when you feel hungry you should eat the amount of food allowed until you feel satisfied.
  8. Always verify that foods are low in carbohydrates by reading the product label.
  9. It is possible to eat out, but always paying special attention to the carbohydrates hidden in dressings and sauces that often have sugar.
  10. Avoid both food and drinks sweetened with aspartame, it is preferable to consume those that use sucralose or saccharin, taking into account that each bag is equivalent to 1 gr. carbohydrates.
  11. Avoid coffee and all caffeinated beverages.
  12. Drink at least 8 glasses of water of 250 cc each.
  13. Take at least one multivitamin with minerals.

During the Induction stage it is possible to eat unlimited fish, poultry, seafood, red meat and eggs. It is only necessary to take into account:

  • Limit the consumption of oysters and clams to 120 grams. daily as they have higher carbohydrate content than other shellfish.
  • Always be careful to verify that processed meats and sausages have not been prepared with sugar. The same applies to processed fish and poultry that may contain starches and starches.
  • It is preferable to avoid cheese in the first phase of Induction and if you want to include it in the menu it should not exceed 120 grams. daily hard, semi-soft and white cheeses, such as cheddar, cow’s or goat’s cheeses, cream cheese or gouda.
  • The only carbohydrates that can be consumed at this stage are vegetables, but only those that are allowed and only 3 cups per day.
  • Possible salad dressings can be boiled egg, sautéed mushrooms, sour cream, spices without sugar, oil, vinegar (not balsamic or Modena), lemon juice.
  • Fats are important in the Atkins Diet and the most acceptable are olive, canola, soy, sesame and grape seed oil, preferably those that have been processed with a cold press, avoiding very high temperatures to use them. As for butter, it is allowed and margarine should be avoided because it is produced based on trans fatty acids.
  • Artificial sweeteners, only sucralose is recommended since it does not contain calories and does not alter the blood sugar level, avoiding the use of aspartame as it slows down weight loss.
  • As for the drinks that can be consumed in this first stage, in addition to the eight glasses of water per day, coffee and tea only if they are decaffeinated, all kinds of infusions are also allowed.
  • There are foods of a special category that serve to have greater menu options. For example, you can take up to 20 olives a day, half an avocado and up to 2 tablespoons of cream, 2 tablespoons of lemon juice. Whereas packaged meals can be taken in the Induction stage but always keeping in mind that they are low in carbohydrates.

Extended Induction Phase (Optional)

The induction phase should last no less than 15 days. However, the amount of kilos that must be lost has a lot to do with it and for this reason there is Extended Induction in the Atkins Diet to extend the first stage for 15 more days before moving on to the PPP phase (Progressive Weight Loss).

Therefore, those who have to lose a lot of weight or have difficulties to lose it easily can continue the induction for a few more days, achieving better results before moving on to the next phases of the program, taking into account that the PPP phase can slow down the process of weight loss, something that is not bad, since the slower the progress, the greater the opportunity to change bad eating habits.

Therefore, if you are bored with the induction phase and do not want to continue with it for another 15 days, when the number of kilos to lose is not significant or you want to slow down the weight loss progress in exchange for a more varied diet , nothing prevents going to the PPP stage.

Progressive Weight Loss Phase (PPP)

This is an interesting phase because it helps to know your own metabolism. The PPP stage does not differ much from the Induction stage, but it has the advantage that it allows adding a greater variety of foods that were previously prohibited, and it is also possible to increase the 20 grams. of daily carbohydrates doing it gradually and until you know how many grams of carbohydrates the body supports before gaining weight again.

Rules of the PPP Phase

In the PPP phase, certain rules must also be met since food is added and, as will be seen later, these are divided by steps:

  • Fat and protein are still the main foods in the diet.
  • Daily carbohydrate intake is increased but not more than 5 net grams per week.
  • New foods are added in this order:
  1. Salads and other vegetables.
  2. Dairy, fresh and aged cheeses.
  3. Nuts (walnuts, pistachios, almonds).
  4. Fruits such as strawberries and berries or cantaloupe.
  5. If desired, wine and other low-carbohydrate alcoholic beverages can be added.
  6. Vegetables.
  7. Other fruits outside of the list of the first stage.
  8. Vegetables that contain starch.
  9. Whole grains
  10. Add new foods one at a time
  11. Eat each group of new foods no more than three times a week to start and gradually more days will be implemented.
  12. If new foods cause weight gain, stop eating them.
  13. Continue with the PPP Phase until you only need to lose between 2 and 4 kilos.
  14. It is possible in this phase to stop at each step for as long as desired and if a group of meals is preferred, up to 5 grams can be added. net more from that same group.
  15. You can also skip a step if the foods are not to the taste of those who follow the diet, but taking into account that they are ordered by nutritional importance and also by glycemic load.

Foods not allowed on the Atkins Diet

As the allowed foods are determined in each Phase of the Atkins Diet, it is necessary to also take into account the prohibited foods in the Atkins diet, which are the following:

  • Bread and pastries.
  • Ice cream, sweets and cookies.
  • Pasta, cereals and rice.
  • Milk and yogurt.

Contraindications of the Atkins Diet

The Atkins Diet may be perfect for those who like to eat meat in large quantities, in addition to other foods such as eggs or bacon, while other carbohydrate-rich foods such as pasta, certain vegetables and desserts are totally prohibited, at least during the early phases of the plan.

For many people it can be a difficult diet to follow, especially if you like to eat a lot of vegetables, and it is not recommended for people with heart, kidney or diabetes diseases.

On the other hand, the detractors of the diet affirm that the low consumption of vegetables and fruits during the phase with which the program begins, can cause a significant lack of essential minerals and vitamins, while due to its low content in foods with fiber it will cause constipation.

 Advantages and Disadvantages of the Atkins Diet

Since most Atkins weight loss diets have their advantages and disadvantages, both are important when choosing a weight loss plan that suits the needs of each person.

Advantages of the Atkins Diet

The latest version of the Atkins Diet expands the examples of certain foods that can be added in the different stages of the plan, including the type of fats that now gives greater importance to the consumption of monounsaturated and polyunsaturated, limiting the consumption of saturated and eliminating the Trans fat.

Another group of foods such as carbohydrates is also detailed, allowing the “good” ones such as those found in fruits and vegetables and that provide fiber, vitamins and minerals.

The consumption of protein helps to have a greater sensation of satiety and the body burns more calories when digesting proteins than carbohydrates, thus making an extra expenditure of energy.

Disadvantages of the Atkins Diet

As it is a diet with different phases, in the first phase, carbohydrates are almost totally ruled out for 15 days, although the objective is that during that period of time a few kilos are lost, the amount of carbohydrates to consume is very little .

On the other hand, doctors do not consider it appropriate to follow the first phase for more than 15 days because despite losing more weight it is unhealthy.

Video on the Atkins Diet

This educational series and fun videos explain everything you need to know about how to lose weight on the New Atkins Diet.

Atkins diet considerations

Carbohydrates and fats provide the body with the energy it needs on a daily basis, but the Atkins Diet pays special attention to carbohydrates as a priority source and hence limiting carbohydrate intake forces the body to convert accumulated fat into energy and this translates into in weight loss.

However, before starting this diet to lose weight, it is necessary to consult a doctor since each person has a different level of carbohydrate balance and according to the Atkins Diet, excess carbohydrates causes the body to store fat again and gain weight.
