The researchers found that weight loss was similar over a year for people on a low-egg (two a week) and a high-egg (12 a week) diet.

They discovered that even participants with Type 2 diabetes did not suffer adverse effects from eating a diet high in eggs such as inflammation, cardiometabolic risk levels or raised glucose levels.

“A healthy diet based on population guidelines and including more eggs than currently recommended by some countries may be safely consumed,” concluded the researchers.

It has prompted a call for a review of the National Heart Foundation guidelines, which recommend just six eggs a week.

While eggs are high in fat, they are full of vitamins, minerals, protein and healthy omega-3 fats. The yolk is packed with nutrients, so there’s no need to opt for egg whites only.

Eggs do not significantly raise cholesterol in the blood, the Mayo Clinic reports, and people who replace a grain-based breakfast with eggs have been found to eat fewer calories over the day.
