Eggs Depending on who you ask, eggs are either the best thing ever or terrible. One thing's for sure: one hard-boiled egg has six grams of protein, which is 14 percent of a woman's daily protein intake. A study found that eating eggs for breakfast influenced ghrelin (the hunger hormone) and induced greater satiety for the next 36 hours. Toss it on top of toast, or eat one on the go!
