The benchmark protein snack: 78 calories and 6 g of protein per large egg. On the energy-density scale, 155 kcal per 100 g puts egg at the moderate end. Protein density is strong: about 8.1 g of protein per 100 calories.
A typical serving (1 large egg, 50 g) has about 78 calories, and 100 g has 155 kcal. Calories scale with weight, so double the portion means double the number.
There are 12.6 g of protein in 100 g of egg, which works out to about 6.3 g per serving (1 large egg). That is a genuinely high protein share for the calories.
Yes, in the plain arithmetic sense: 10.6 g of fat per 100 g supplies about 62% of the calories. Whether that fits your day depends on your totals, not on the food alone.
