Well if you don't use a ton of oil or you're not eating 10 pieces at once, you shouldn't worry. Eggs are well balanced in terms of nutrition and this is why many bodybuilders eat a lot of eggs. Eggs are considered to have the highest biological value for protein. One medium egg contains around 75 calories, 7 grams of high-quality protein, and 5 grams of fat (in the egg yolk). But! Pay attention that even the eggs are low in saturated fat and they are a perfect source of proteins, although, the egg yolks are also high in cholesterol. So, if you are eating more eggs daily, consider limiting the number of egg yolks. Egg whites, you can eat safely without feeling guilty.
