Energy comes from USDA nutrient 1008. Salt is calculated as sodium × 2.5, with unit conversion to grams. It is not a separately measured salt value.
Preparation
Boiling an egg in water does not add cooking fat. This hard-boiled record provides 155 kcal per 100 g; the raw record provides 143. Their difference does not prove a specific water loss for your egg, because they are separate database records. Use the cooked record for a peeled boiled egg, and add mayonnaise, butter or other ingredients separately.
Logging this food
Weigh the peeled egg or choose the matching size. The large serving here is 50 g, about 1.8 oz, and roughly 78 kcal; two are about 155 kcal before toppings. A shell contributes weight but is not part of the edible portion. If you remove the yolk, use a suitable egg-white record rather than treating the remaining egg as a whole egg.
Swaps and alternatives
Compare the whole egg and egg-white entries using the portion you actually eat. Removing a yolk changes both calories and nutrients; it is not simply a lower-calorie version of an otherwise identical food. Poached, fried and scrambled records also describe different preparations. Include bread, toppings and cooking fat when comparing complete breakfasts.
Questions about a hard-boiled egg
How many calories are in 2 boiled eggs?
Two large hard-boiled eggs, each 50 g peeled, provide about 155 kcal and 12.6 g protein using this record. A different size needs a different weight; soft-boiled eggs are not measured by this hard-boiled record.
How many boiled eggs is 300 calories?
About four large hard-boiled eggs, which come to roughly 310 kcal and 25 g of protein. Three eggs are about 235 kcal.
Is a boiled egg high in calories?
No. At 78 kcal per large egg with 6.3 g of protein, a hard-boiled egg gives about 8 g of protein per 100 kcal — one of the better protein-per-calorie ratios among whole foods. What makes an egg breakfast high in calories is the butter, bacon and toast around it.
How many calories are in the white of a boiled egg?
For a plain egg white, select an egg-white record and the edible weight rather than subtracting a raw yolk value from a boiled whole egg. As a separate reference, one large raw egg white (33 g) has about 17 kcal and 3.6 g protein. Preparation and size can differ.
