Hard-Boiled vs. Omelet: Which Keeps You Fuller?

In every Israeli breakfast, eggs are a staple, served in various preparations. But is there a difference in satiety between a hard-boiled egg and an omelet? Dr. Maya Rozman addressed this topic on her 103FM radio show and busted a myth.

Rozman stated that in theory, both a hard-boiled egg and an omelet, when fried in oil, have the same amount of protein, fat, and calories. However, she noted that many people believe that a hard-boiled egg is more filling than an omelet. "I conducted a survey on Instagram, and most people said a hard-boiled egg fills them up more," she said.

Rozman explained, "The stomach needs to knead the egg into a mash, which is much easier to do with an omelet as opposed to a hard-boiled egg that requires much more energy and time to knead and digest."

She gave another example to support her claim, stating, "Why does a whole apple satisfy more than an apple smoothie? Because the stomach works harder to digest and knead the whole apple, it also takes more time to chew a whole apple compared to a smoothie that is quickly drunk, leaving nearly no work for the stomach," she said, adding that "a baked potato is more filling than mashed potatoes, because the glycemic index of a boiled potato is higher compared to baked ones. This means it satisfies for a shorter period and is less suitable for diabetes."
