Is Atkins Healthy?

The Atkins Diet, a renowned low-carbohydrate eating regimen, was formulated in the 1960s by cardiologist Robert C. Atkins. Touted for its unique approach to weight loss, this diet has sparked numerous debates regarding its health implications.

Is Atkins Healthy?

The Atkins Nutritional Approach suggests that it can combat or even ameliorate severe health ailments like metabolic syndrome, diabetes, high blood pressure, and heart disease. Indeed, weight loss from any diet, including Atkins, can potentially decrease or reverse the risks associated with heart disease and diabetes. While studies have demonstrated improved triglyceride levels with Atkins, indicating better cardiac health, comprehensive studies examining long-term benefits or life expectancy are lacking. Some health professionals also express concerns about the high consumption of animal-based fat and protein on the Atkins Diet, linking it to heart disease and certain cancers.

How Does Atkins Work?

The Atkins Diet uniquely emphasizes not restricting fat intake and avoids the hassle of calorie counting or portion measuring. However, it mandates meticulous carb counting. The concept behind this is when carbs are restricted, the body resorts to burning stored fat, producing ketones for energy.

Phases of the Atkins Diet

  • Phase 1: Limits intake to 20 grams of net carbs daily, aiming for rapid weight loss.
  • Phase 2: Allows up to 30 net carbs daily, slowing the weight loss rate compared to Phase 1.
  • Phase 3: Increases the net carb limit by 10 grams weekly until the desired weight is achieved.
  • Phase 4: Maintenance phase permitting up to 120 net carbs daily to sustain the target weight.

Risks of the Atkins Diet

The Atkins diet, though effective for many in shedding pounds, isn’t devoid of criticisms:

  • Allows Processed Meats: Processed meats might elevate risks of heart conditions and certain cancers. Yet, many Atkins followers consume them due to their low carb, high-fat content.
  • Excludes Healthy Foods: Vital fruits and vegetables are sometimes limited to maintain the carb ceiling, potentially leading to nutrient deficiencies.
  • Has Side Effects: Potential side effects include electrolyte imbalances, constipation, low blood sugar, and kidney issues.
  • Promotes Processed Foods: The diet’s commercial side includes bars and shakes, which often contain undesirable ingredients. Processed ingredients and artificial sweeteners may harm health in the long run.
  • Questionable Long-Term Benefits: Comprehensive studies on the diet’s long-term health effects are sparse, with most research spanning only a year or two.


For those considering the Atkins Diet, adopting a whole foods approach is recommended. Emphasise healthy fats and carbs, and avoid excessive processed foods. Always consult a healthcare professional, especially if dealing with specific health conditions or life stages like pregnancy.


1. Is Atkins healthier than keto?

The maintenance phase of the Atkins diet is richer in protein compared to keto and is more lenient with carbs. Research indicates that an Atkins-style diet with reduced saturated fat and higher protein can assist in weight maintenance and diminish heart disease risks.

2. Which is faster, keto or Atkins?

Keto tends to yield quicker results than Atkins due to its consistent carb restriction. In contrast, Atkins saves more carbs for later phases. Neither diet excludes fat or protein.

3. Why did Atkins diet fail?

One reason the Atkins Diet faces criticism is its potential to cause significant hormonal shifts, particularly affecting the thyroid. Evidence suggests low-carb diets can hinder the conversion of T4 into the active thyroid hormone, T3.

Beyond Atkins, many people also inquire about the health implications of diet drinks like Diet Pepsi.
