Why does a fried egg have more energy than boiled egg?

That's a bit of a misconception! A fried egg and a boiled egg actually have approximately the same amount of energy (calories).

Here's why:

* Energy comes from the food itself, not the cooking method. The calories in an egg come from its protein, fat, and other nutrients. Whether you boil, fry, poach, or scramble an egg, you're not changing the composition of these nutrients.

* Slight variations exist. There might be very small differences in calorie content due to the amount of oil used in frying. However, this difference is usually negligible.

So, the amount of energy in an egg is primarily determined by the size and type of egg, not the cooking method.
