You've probably read news stories about famous fitness figures who eat 10, 15, or even 20 eggs a day. The fact is, eggs are one of the favorite foods for those looking to gain weight and build muscle mass.

Of animal origin and of high nutritional value, the egg can provide a reasonable amount of calories , proteins and several essential vitamins for our body.

A medium egg (50g) has around 65kcal of calories. 50kcal are in the yolk and 15kcal are in the white. In addition, an egg can provide 6.5 grams of protein and 1.07 grams of carbohydrates.

As you may have seen, just one egg is not enough to generate any results in your physique. However, because it is easy to digest and easy to prepare, it is possible to eat more than one during the day.

If we do the math, around five units can provide 325 calories, 32 grams of protein and 5.35 grams of carbohydrates.

For those looking to gain muscle mass, it is recommended to consume 1.2 to 2 grams of protein per kilo of body weight/day.

The amount of calories depends a lot on the strategy you adopted in your diet. For example, to gain one kilo of fat, you need to consume about 7,000 calories more than your basal metabolic rate.

So, you would need to eat about 107 eggs to gain one kilo of fat. That may seem like a lot, but if you divide that into a month of 30 days, that's just 3.5 eggs per day.

It is worth noting that this will only be possible if your daily diet already provides the same amount of calories that your body needs to maintain your weight. Therefore, the calories provided by these 3.5 eggs will generate a caloric surplus.
