Is Atkins Diet Good for Heart Disease?

Why Atkins Diet  helps for Heart Disease

The Atkins diet may help reduce some cardiovascular risk factors by promoting weight loss and improving blood sugar and triglyceride levels. However, its effects on cholesterol vary, and evidence that it directly prevents heart attacks or strokes remains limited.

The Atkins diet restricts carbohydrate intake and replaces some carbohydrate-rich foods with sources of protein and fat. By reducing carbohydrate intake, it may help improve blood sugar control and lower elevated triglycerides. It may also support weight loss, which can improve several cardiovascular risk factors, including blood pressure and insulin resistance. Research comparing low-carbohydrate diets with low-fat diets has found benefits for weight loss and triglycerides, although LDL cholesterol may increase in some people.

The quality of the foods chosen is also important. A study published in the New England Journal of Medicine, titled “Low-Carbohydrate-Diet Score and the Risk of Coronary Heart Disease in Women,” found that a low-carbohydrate dietary pattern emphasizing vegetable sources of fat and protein was associated with a 30% lower relative risk of coronary heart disease compared with the lowest-scoring group.

However, the study was observational and did not establish that the diet itself caused this reduction. The corresponding pattern emphasizing animal sources of fat and protein was not associated with a significant reduction in risk.

Therefore, a heart-conscious approach to Atkins should emphasize unsaturated fats, such as those found in olive oil, nuts, seeds, avocado, and oily fish, rather than relying heavily on butter, fatty processed meats, and other sources high in saturated fat. This may help support a healthier cardiovascular risk profile while following a low-carbohydrate diet.

How Atkins Diet works for Atherosclerosis

The Atkins diet works to reduce the risks of heart disease and even prevent them, by lowering carbohydrates consumption and incorporating a variety of healthy fats and meat in the diet. 

This is done mainly by influencing the various risk factors associated with heart disease.

Hereafter, we cover in details how the Atkins diet works to achieve this:

- Lower bad cholesterol: small particles of low-density lipoprotein (LDL) pose a higher risk of heart diseases. Current researches suggest that low-density lipoprotein (LDL) are associated with a higher consumption of carbohydrates.

A study titled “Effect of short-term low-and high-fat diets on low-density lipoprotein particle size in normolipidemic subjects” provided evidence that following a low carbs diet that is high in fat can increase the size of (LDL) particles or bad cholesterol, and at the same time decrease the percentage of small LDL particles. 

Accordingly, by lowering carbohydrates consumption, the Atkins diet is believed to decrease the percentage of small LDL particles, and this aspect would lower the risks of heart diseases.

- Increase good cholesterol levels: people with low levels of HDL or good cholesterol are at greater risk of heart diseases.  Current researches suggest that lower levels of HDL are associated with a higher consumption of carbohydrates. 

A review study titled “Effects of Low-Carbohydrate Diets Versus Low-Fat Diets on Metabolic Risk Factors: A Meta-Analysis of Randomized Controlled clinical Trials” showed that following a low-carb diet increases HDL levels more than following a low-fat diet.”

Accordingly, by lowering carbohydrates consumption, the Atkins diet is believed to increase the level of HDL, and hence would lower the risks of heart diseases. Plus, this diet promotes good fat which would increase further the HDL level.

- Lower triglyceride levels: it is commonly known that high levels of triglycerides in the blood increase the risk of heart diseases. Current researches suggest that these elevated levels of triglycerides are associated with the consumption of carbohydrates, especially refined sugars. 

A review study titled “Effects of Low-Carbohydrate Diets Versus Low-Fat Diets on Metabolic Risk Factors: A Meta-Analysis of Randomized Controlled clinical Trials” showed that a low-carb diet decreased triglycerides levels in all populations. 

By lowering carbohydrates consumption, especially refined carbs and sugar, the Atkins diet is believed to reduce the level of triglycerides in the body. Hence, this would lower the risks of heart diseases.

- Reduced blood sugar levels: it is commonly known that high blood sugar levels and diabetes are both factors that can lead to heart diseases. 

Current researches suggest that increased blood sugar levels and insulin secretion are associated with high carbohydrates diet consumption.

A study titled “The Effect of Low-Carbohydrate Diet on Glycemic Control in Patients with Type 2 Diabetes Mellitus” showed that a low carb diet can improve blood sugar levels more than a low-fat diet.

Accordingly, by lowering carbohydrates consumption, the Atkins diet is believed to reduce blood sugar and insulin levels, and hence would lower the risks of heart diseases. To learn more about this, you can check the section on Atkins diet for diabetes. 

- Lower blood pressure: it is commonly known that hypertension is a risk factor leading to heart diseases. Current studies have shown that low carbs diets, may be helpful in reducing high blood pressure levels. 

Accordingly, by lowering carbohydrates consumption, the Atkins diet is believed to reduce hypertension, hence lowering the risks of heart diseases.

- Weight loss: being overweight is commonly known to be a risk factor leading to heart diseases. 

Current researches have shown that excessive consumption of carbohydrates and sugar leads to weight gain. Therefore, limiting these elements in the diet can help reducing weight. 

The Atkins diet, being low in carbs, is believed to contribute to weight loss. This happens mainly because in the absence of carbs, the body is forced to burn fat for energy, hence fat storage gets reduced in the body.

Atkins Diet foods for Atherosclerosis

The Atkins diet restricts carbohydrate and stresses on protein and fat intake. Supporters of this diet recommend it as an everlasting regimen that should be followed as a lifestyle across the individual’s lifespan for healthier outcomes.

The Atkins diet promotes foods that are considered low in carbohydrates or carbohydrate-free for consumption. These foods include:

-    Fish and seafood

-    Pork, turkey, and chicken

-    Eggs

-    Non-starchy vegetables such as spinach, broccoli, lettuce, cucumber, kale, asparagus…

-    Unrefined oils such as olive oil, coconut oil, walnut oil… 

-    Full fat dairy including butter, heavy cream, sour cream, and hard cheeses that are high in fat and low in carbohydrates such as blue cheese, American cheese, Swiss, cheddar, feta …

-    Herbs and spices

Atkins Diet for Heart Disease: What you should Avoid

The Atkins diet restricts carbohydrates consumption and tends to eliminate many foods based on their carbohydrate content. Accordingly, the diet removes the following foods from the regimen:

- All types of grains, legumes, and starches

- Sugar and alternative sweeteners

- Sugar sweetened beverages and drinks

- Most fruits and vegetables that are high in carbohydrates

- Starchy vegetables such as potatoes and corn

- Vegetables oils like corn oil, canola oil, soybean oil …

- Condiments including bagged sauces and mixes

- Most dairy products that are high in carbohydrates such as milk, yogurt, and cottage cheese

- Alcohol

- Reduced fat and diet products

Atkins Diet for Heart Disease: precautions

There are several side effects that might come along when you follow a low carbohydrate diet such as the Atkins diet. When there is an elimination or even restriction of carbohydrates from the diet, symptoms such as fatigue, weakness, headaches, sleep disturbances, trouble breathing, irritability and mood swings, and bad breath might occur.

Digestive problems also happen with the Atkins diet due to several reasons such as constipation and diarrhea. Even nausea might follow as a result of inadequate fiber intake secondary to carbohydrate restriction.

Another important factor to pay attention to is nutritional deficiencies. Certain vitamin and mineral deficiencies are prevalent when omitting a food group or certain food types. The Atkins diet restricts carbohydrates and fruits, and this increases the risk of nutritional deficiencies.

Always consult with a healthcare professional before starting any new treatment.

Additional precautions for patients with Diabetes

An additional complication can happen if the body is accumulating high amounts of ketone bodies that can show up in the blood and urine. This is known as a diabetic ketoacidosis (DKA), and is a serious complication for patients with diabetes. It can be life threatening and dangerous, and therefore people following an Atkins diet should always do proper monitoring and conduct regular tests to check their blood and various health indicators.
