In an era where numerous diets vie for attention as effective weight loss solutions, the egg diet has emerged as a popular trend. This article delves into the details of the egg diet, examining its potential benefits, risks, and overall effectiveness.
What is the Egg Diet?
The boiled egg diet is a dietary pattern characterized by a high intake of eggs, combined with lean protein sources, non-starchy vegetables, and low-carbohydrate fruits. It's designed to be a low-calorie, low-carbohydrate approach to weight loss, with claims of achieving up to 25 pounds of weight loss in just two weeks.
Potential Benefits of the Egg Diet
- High-Quality Protein Intake: Eggs are a complete protein source, providing all nine essential amino acids necessary for muscle building and repair.
- Eye Health: Eggs contain lutein and zeaxanthin, antioxidants that support and maintain good eye health.
- Brain Health: Choline, a nutrient abundant in eggs, plays a crucial role in supporting brain function.
- Heart Health: Contrary to past concerns about cholesterol, moderate egg consumption can be part of a heart-healthy diet. Eggs may also shift LDL cholesterol particles from small, dense forms to larger ones, potentially reducing heart disease risk.
- Convenience and Versatility: Boiled eggs are easy to prepare and can be used in various meals and snacks.
Hen’s eggs (from Gallus gallus domesticus) provide choline, folate, vitamin D, iodine, B vitamins and high-quality protein and are no longer viewed by national bodies as a risk factor for hypercholesterolaemia and cardiovascular disease (CVD).
Potential Risks and Drawbacks
- Restrictive Nature: The egg diet is highly restrictive, limiting food variety and potentially leading to nutrient deficiencies if followed for extended periods.
- Calorie Restriction: The diet's low-calorie nature may be too restrictive for some individuals, potentially leading to health issues like decreased bone density, low energy levels, and a slowed metabolism.
- Sustainability: The weight loss achieved on the egg diet may be short-term, with the likelihood of regaining weight upon returning to regular eating habits.
- Dietary cholesterol and saturated fat: Each boiled egg has 186 milligrams (mg) of cholesterol. One study concluded that each additional 300 mg of dietary cholesterol consumed per day was associated with a 17 and 18 percent increased risk, respectively, of cardiovascular disease and death from any cause. Each large egg contains 1.6 g of saturated fat. A diet high in saturated fat can lead to high LDL, or “bad,” cholesterol, levels, raising your risk of heart disease.
Sample Meal Plans
While the egg diet allows for some flexibility in meal planning, here are examples of daily menus:
- Breakfast: Citrus fruit and two hard-boiled eggs.
- Lunch: Steamed chicken filet or a low-calorie salad with Greek yogurt.
- Breakfast: Citrus fruit and two hard-boiled eggs.
- Lunch: Grapefruit and roasted fish.
- Breakfast: Citrus fruit and two hard-boiled eggs.
- Lunch: Salad with two boiled eggs.
Evidence-Based Considerations
While the egg diet may lead to short-term weight loss due to its low-calorie and low-carbohydrate nature, it's crucial to consider the scientific evidence.

- Weight Management: In several RCT, eggs increased muscle protein synthesis and lowered fat mass, which could support optimal body composition. Eggs within a meal improved satiety, which could translate into lower energy intakes, although more RCT are needed.
- Cardiovascular Health: In observational studies, higher egg consumption was associated with a null effect or a modest reduced risk of CVD.
- Type 2 Diabetes: For type 2 diabetes (T2D) incidence and risk of CVD in people with T2D, there were inconsistencies between observational and RCT data, with the former noting positive associations and the latter seeing no effect of higher egg intake on markers of T2D and CVD.
- Nutrient Density: Eggs are a moderate energy, nutrient-dense food providing 66 kcal, 6.4 g of protein and a wide range of micronutrients per medium egg. A medium sized egg contains 4.6 g of total fat, with 1.7 g of this being monounsaturated fat. Alongside crustaceans and offal, eggs are rich in dietary cholesterol, providing 177 mg per medium egg. Of these, choline, vitamin D, folate and iodine are provided by eggs in clinically useful quantities.
Important Nutrients Found in Eggs
- Choline: Eggs are a rich source of choline, an essential nutrient for infant growth and development. They can boost choline status in groups with higher requirements and typically low intakes.
- Vitamin D: Eggs are one of the few foods naturally high in vitamin D, helping to minimize deficiencies, especially during winter months.
- Folate: Eggs can contribute to higher folate intakes, which is particularly important for women of childbearing age to protect against neural tube defects.
- Iodine: Eggs are high in iodine, an essential nutrient for normal foetal brain development, making them a useful addition to the diet before and during pregnancy.
- Protein: Eggs are considered a source of high-quality protein since they contribute all nine essential amino acids.
Recommendations
Before embarking on the egg diet or any other restrictive eating plan, it's crucial to consult with a healthcare professional or registered dietitian. They can assess your individual needs, health status, and goals to determine the most appropriate and sustainable approach to weight loss and overall well-being.
Alternatives to the Egg Diet
If the egg diet seems too restrictive or unsustainable, consider exploring alternative eating patterns:
- Mediterranean Diet: Emphasizes whole grains, fruits, vegetables, legumes, and heart-healthy fats.
- Low-Carbohydrate Diets: Focus on reducing carbohydrate intake while emphasizing protein and healthy fats.
- Balanced Meal Plans: Incorporate a variety of nutrient-dense foods in appropriate portions to meet your individual needs.
