Eating protein has been linked to losing weight. As a 2012 study from The Journal of Nutrition concluded, regular daily intake of protein tempered individuals’ tendencies to keep gaining weight. Similarly, a 2014 study from Nutrition & Metabolism noted that, when ingested in moderation, high-protein foods could improve satiety as well as boost the body’s metabolism by increasing the “thermic effect.”
What is the thermic effect? As described by a 2019 review from the Journal of the American College of Nutrition, the thermic effect is a metabolic change that occurs after eating a meal. Essentially, as the body converts food into energy, the body’s normal metabolic propensity can start to increase. Though consumption of fat doesn’t seem to produce a significant thermic effect, consumption of protein does.
Is protein the only reason to pick up a carton of eggs during your next healthy grocery shopping trip? Nope. Another possible weight-control benefit of eggs is their vitamin D content. Healthline explains that a single egg can provide about 5% of the average adult’s recommended daily value of vitamin D. And guess what vitamin D has been connected with? Body fat loss.
In a 2019 clinical randomized trial published in Clinical Endocrinology, obese study participants who upped their vitamin D intake saw a decrease in their body fat and mass. Therefore, bringing more vitamin D into your snacking by way of a couple of hard-boiled eggs could give you a delicious way to stay fit.
