The grease isn't in the pan anymore. It goes somewhere.
A half tablespoon of oil (60 calories) is a small thing, but relative to what you're cooking in it (150 calories worth of egg), it pretty significant. Especially if somebody is tracking all those individually insignificant things in an effort to not be a fatass.
Well, then track a half tablespoon of oil or butter.
You're not adding that to every single meal, are you? So is it that hard to account for one more ingredient in your breakfast?
And those kinds of fats are also what help you feel satiated for longer. Fats, proteins, and fibers, add more of each to your diet, use moderation, and with just a little bit of attention to the effort, you can lose weight and feel better too.
People far too often lump all fatty acids into some OMG-THE-DEVIL type of belief pattern. And all too often they think fat = fatty tissue. While lipids do go into adipose tissue, this is only made problematic when you consume an abundance of processed and high-carbohydrate meals, which the body greatly prefers to use for energy rather than the more energy-intensive (comparatively) method of breaking down fatty acids for fuel. So excess carbohydrates = oh, well I guess I ought to store these lipids away for later, it might be important... who knows when my next meal will be! Our physiology is primitive, and metabolism is decoupled from a conscious understanding of the world. Which is to say, it'll act like a primal animal when it comes to food, because we can't convince it to do otherwise.
