Research
For most healthy people, no. Up to about one egg a day is not linked to higher heart disease or stroke risk in large studies. Eggs nudge blood LDL up a little, but the net effect is small. The bigger issue is what you eat with them, a fry up is not 'an egg'.

Research
For adults, no, and it is not 'the most important meal' for weight. Trials show adding breakfast doesn't aid weight loss (slightly the opposite), skipping it doesn't slow your metabolism, and the observational skipping obesity link is weak and confounded. Eat it or skip it by hunger.
