When it comes to eating well, people tend to focus on things like fat and calories. There is a lot of talk about specific foods and food groups you should or should not eat. What many people do not always take into consideration is protein intake. Not getting enough can have negative effects on your health. Yahoo spoke to dietitians for the information you need to make sure you are getting the right amount:
What is protein and what are its benefits?
“Protein is a source of both macronutrients and micronutrients that our body needs to maintain a healthy and strong body,” Jennifer Beery, RD, LDN, a registered dietitian at Orlando Health, tells Glamour. “Just like carbohydrates and fats, protein, which is made up of amino acids, provides a source of calories but is also a source of beneficial B vitamins, Vitamin E, iron, zinc, and magnesium that are important for building and maintaining healthy bones, muscle, blood, and skin.”
Protein has countless health benefits, adds Amber Ingram, RD, CSO, LD, a registered dietitian at the Ohio State University Wexner Medical Center, “including helping you to feel full, blood-sugar stabilization, and preserving muscle mass.” It can also help with wound healing and tissue building; providing energy; maintaining healthy skin, hair, and nails; and helping the body to make hormones, she says…
What happens if you don't eat enough protein?
Eating inadequate protein can lead to muscle loss, inelastic skin, and thin fragile, hair, says Ingram. “Loss of muscle mass can cause your metabolism to slow down, making any weight-loss goals more challenging, and you may also find your meals are not as satisfying and you may experience more hunger in between meals,” she explains.
You may also notice weakness, fatigue, and decreased immune function, adds Beery. “This is because your body will break down your own muscle mass to create necessary proteins for the body perform necessary functions.”
On the other hand, it’s also possible to eat too much protein, though it’s rare. “Risks for excess protein in the diet is considered low, however some may experience gastrointestinal side effects or there may be an increased risk of kidney stones,” says Beery. “However, data is conflicting and further research is needed on the effects of excess protein intake.”
How much protein do you need in a day?
On a very basic level, the Recommended Dietary Allowance (RDA) for protein intake is 0.8 grams per kilogram of body weight per day (g/kg/d) for the average adult, according to Ingram. “To determine your weight in kilograms, divide your weight in pounds by 2.2, then multiply that number by 0.8 to find out how many grams of protein to eat per day,” she explains. However, that’s not a perfect solution for everyone.
In fact, according to the AMCR Acceptable Macronutrient Distribution Range (AMCR), protein needs can range from 10% to 35% of total daily calories, Beery adds. This means that more-active individuals or those desiring to build muscle may need up to 1.2 to 1.7 grams per kilogram of body weight per day, while people over 40 or 50 might want to increase their protein intake as that’s when muscle loss can set in.
Protein needs can also depend on whether or not you’re pregnant or actively losing weight, and a variety of other factors, so it’s always best to work with a registered dietitian to help calculate your specific energy and protein needs, depending on your nutrition needs and personal health goals.

Eating well doesn’t have to be complicated. It doesn’t take a fad diet or sacrificing the things you love. It comes down to balance.
