Protein-rich foods are amongst the best options for boosting metabolism. Eggs are rich in protein, with each large, hard-boiled egg containing 6.29 grams, making them an ideal choice for people who want to speed up their metabolism. Protein is one of the most effective nutrients for increasing metabolic rate because the body needs to use more energy to digest it than it does for fats or carbohydrates.
They’re also a good source of B vitamins, which have been shown to boost metabolism. B vitamins help convert the foods you eat into energy, so they help with processing those calories better and using them for energy.
