Protein: Too Little or Too Much

Blog category:
Fitness Tips

We’ve all heard the importance of eating a balanced diet of protein, carbohydrates, vegetables, and fats, but what we don’t often hear about is why it’s important and how too little or too much of these essential foods can impact our bodies.

Protein is essential for restoring and forming muscle, hormone production, staying full, bone health, and more; but does too little or too much protein have negative side effects?

Let’s read more about it!

Too Little Protein

A low-protein or protein-deficient diet is typical and can cause health problems.

Weight Loss—We’re not talking the good kind, like losing body fat. Instead, overall weight loss is a result of a low-protein, and most likely, a limited calorie diet. If you’re not getting enough calories, your body will use protein as a fuel source first rather than adding muscle.

Muscle Loss—Protein helps build muscle, but like we stated above, if your protein is being used for fuel, you won’t gain or even maintain muscle and can even start losing muscle mass. As we get older (usually around age 35 for women and as early as age 25 for men), we usually start losing muscle mass.

Liver Issues—Certain portions of our bodies need different nutrients to function properly. Protein is essential for healthy liver functions. Not enough and you could end up with liver disease.

Joint Pain—Strong, healthy muscles help keep joints in place. Protein is used to add and repair muscle, but with a limited or protein-deficient diet your protein is going to be used as a main fuel function, rather than building muscle to keep joints strong and stable, which could lead to achy joints.

Low Blood Pressure—This may not seem like a problem, however low blood pressure lowers the stream of essential nutrients and oxygen to vital organs and tissue. In addition, you could end up with anemia, which occurs when your body can’t create enough red blood cells.

Edema—This is a condition in which swelling appears, often in the hands, feet, and ankles, from body fluid trapped in the tissue. Protein helps keep fluids from building up in tissue. If you notice swelling in these areas, it could be a symptom of low protein consumption.

Immune System & Recovery—Your immune system needs protein to remain healthy. If you’re getting sick more often or can’t beat those common colds, it could be from low protein consumption. It’s the same with recovering from an injury. Proteins are needed to fix tissue and muscle. It will take more time to heal an injury if you aren’t eating enough protein.

Cravings—Too many carbs and not enough protein can contribute to unwanted food cravings. If you’re finding yourself wanting more snacks, you’re probably not consuming enough protein and too many carbs.

Too Much Protein

So what about too much protein? While it’s harder to eat too much protein, there are some health concerns and general knowledge about how much is appropriate and how much is “extra.”

Kidney Failure—A common concern of a high-protein diet, kidney failure, is only a risk if you are eating a majority of animal-based protein sources like meat or have a kidney disease. To avoid possible kidney troubles, aim to equalize your protein sources between 50% plant-based and 50% lean, unprocessed meat-based.

Weight Gain—Protein helps build muscle, and like carbs, if we have too much protein it will be accumulated as fat. Our bodies are not good at converting proteins into fat like with carbs, however it eventually does. Like eating too much of anything, weight gain can still occur. A six-year study of 7,000 participants found that those who ate a high-protein diet were 90% more likely to gain up to 10% of their body weight.

Building MuscleMuscle protein synthesis is the action of changing protein amino acids into muscle. New studies have determined that there is a restriction to muscle growth in a high-protein diet, which is about 30 grams per meal. What does that mean? Consuming 30 grams versus 20 grams will help muscle growth, but eating 50 grams per meal won’t have any more positive impact on building muscles. Heavier individuals may need a little more on average, but essentially, there is a cap to protein intake related to muscle growth.

A 2014 study in the Journal of the International Society of Sports Nutrition found that weightlifters who had 5.5 times the recommended daily protein (that’s just over 2 grams per pound of body weight) saw no positive or negative effect on body composition.

Good sources of protein

When preparing your meals and protein sources, we recommend a healthy balance of both plant- and animal-based proteins. When selecting animal-based proteins, choose lean, unprocessed meats like skinless chicken and turkey. Red meat is fine, but keep it lean and always limit the portions. For plant-based proteins, beans, quinoa, nuts, and soy are ideal sources to use.
