Is the Atkins diet safe?-Risks & Benefits

Thinking about trying the Atkins diet but worried about its safety? The Atkins diet emphasizes protein and low carbs. The truth is it’s helped many people lose weight, manage their blood sugar levels, and feel healthier. 

However, many people have voiced concern about the safety of this diet and its long-term effects. This article is based on looking at the Atkins diet to determine whether or not it is safe for people and how it works for them. 

Before starting our discussion of this diet, we will discuss potential risks, benefits, and considerations. Read on to learn more about the Atkins diet and to get more out of this guide.

What is the Atkins diet?

In the 1970s, cardiologist Robert Atkins created the Atkins diet, a low-carbohydrate, high-fat diet based on ketosis principles. As per the diet, consuming carbohydrates leads to weight gain and other health problems since they raise blood sugar levels in the body, leading to weight gain and other health problems. The Atkins diet emphasizes high fat and protein intake while restricting carbohydrates to force the body into ketosis.

Phases of the Atkins diet

There are four phases to the Atkins diet, each with different goals and carbohydrate intake levels.

  • Phase 1 – It lasts for two weeks and is known as the induction phase because it is the most restrictive phase of the process. During this phase, you are only allowed to consume 20 grams of carbohydrates per day, during which you reduce your carbohydrate intake. As the name implies, this phase is designed to kick-start weight loss and get the body into ketosis.
  • Phase 2 – During this phase, you can gradually increase your carbohydrate intake to 30 grams of net carbs daily, starting at a very low level. A slower pace of weight loss is achieved during this phase. Your body will discover what level of carbohydrate intake is best for you in this phase.
  • Phase 3 – Once you have reached your goal weight, you can increase your carbohydrate intake by 10 grams per week until you reach your desired weight. At this stage, you can simultaneously determine how many carbohydrates you can consume and maintain weight loss.
  • Phase 4 – the maintenance phase of the program, is designed to help you maintain your weight for a long time. During this phase, you can gradually increase your carbohydrate intake as long as you maintain a healthy weight of up to 120 grams daily.

Benefits of the Atkins diet

  • Appetite suppression – Added protein and fat to your diet will prevent you from feeling hungry. This will help you stick to your diet plan without feeling hungry all the time.
  • Calorie reduction – A diet restricting carbohydrate intake will eliminate many unhealthy foods from your diet, reducing calories consumed. This diet eliminates empty calories, such as sugary drinks, desserts, and processed foods. This makes it an ideal diet for weight loss.
  • Blood sugar control – For people with type 2 diabetes, eating very few carbohydrates is key to regulating blood sugar levels.
  • Weight loss – Despite its high-fat, low-carb nature, the Atkins diet can help you lose weight.
  • According to some evidence, the Atkins diet might prove more effective for weight loss than conventional diets.
  • Improved cholesterol levels – In addition to improving cholesterol levels, eating an Atkins diet may also lower LDL (high-density) cholesterol levels and increase HDL (healthy) cholesterol levels, which is good news for the heart.

Risks of the Atkins diet

Nutrient deficiencies – The Atkins diet restricts carbohydrates, which may also limit essential vitamins and minerals. In the long run, this may lead to nutrient deficiencies as well as potential health problems due to nutrient deficiencies.

Constipation – The intake of low-carbohydrate foods such as fruits, whole grains, and legumes is limited on a low-carbohydrate diet, which can cause constipation. The digestive process can slow down when the insufficient fiber is in the diet, resulting in discomfort and other digestive issues.

Kidney problems – The Atkins Diet, a diet high in protein, can put a lot of stress on the kidneys, which, over time, can lead to kidney problems due to the added stress.

Increases heart disease risk – Even though the Atkins diet is high in saturated fat, many studies show it increases heart disease risk. Diet could cause health risks, even though it results in weight loss.

It can cause sour breath – The Atkins diet aims to promote a state of ketosis in the body, which can deteriorate breath if the body enters a state of ketosis. It is because ketones, one of the organic compounds produced when fat is broken down, also possess a strong odor.

May lead to muscle loss – As effective as the Atkins diet is at helping you lose weight, some of the weight you lose may be muscle rather than fat due to the diet. When the body does not receive enough carbohydrates, it may turn to muscle for energy.

Increased risk of bone loss – Calcium, critical for bone health, is low on the Atkins diet. Osteoporosis and other bone-related diseases are caused by the body breaking down bone tissue to get calcium.

Not suitable for everyone – If you have kidney disease, liver disease, or another condition that requires a special diet, the Atkins diet might not be right for you. You must consult a healthcare professional before starting to ensure the Atkins diet is safe and appropriate for your health needs and status.

An Overview of the Atkins diet considerations

  • Sustainability – Atkins diets are notorious for being difficult to sustain because they are highly restrictive. Diet guidelines may be hard to follow while traveling or dining out. This means it may be difficult to maintain a weight loss regime when you have to adhere to diet rules.
  • Potential side effects – There is a possibility that some people may suffer side effects during the first phase of the Atkins diet, such as headaches, fatigue, foul breath, and constipation. These side effects can occur in the early stages of the diet.
  • Appropriate for certain groups of people – For women who are pregnant, people suffering from kidney disease, and individuals with a history of disordered eating, the Atkins diet might not be suitable for them. Suppose you are considering using the Atkins diet or any other weight loss plan for the first time. In that case, you must talk with a healthcare provider to ensure it’s safe and appropriate.
  • Social and emotional impact – People may also experience social and emotional effects from the Atkins diet. It’s hard for people on this diet to stick to it if they’re dining out or attending social events. Atkins’s diet can also cause guilt and shame if you slip up, which affects your mental and physical health.
  • Cost – People may also find the Atkins diet pricey since the low-carb, high-fat, high-protein foods are more expensive than regular foods. Some people find meal replacement bars and shake too expensive, making them unaffordable.
