With all the recent boost in protein talk especially for those increasing protein consumption to build muscle mass or for increasing physical activity (think about those new years resolutions!) its probably also a great time to bring up the dangers of protein overconsumption.
While adequate protein intake is incredibly important for your overall health, too much protein can be just as upsetting to the flow of your body.
Alright, but, what exactly does protein overconsumption look like? How do you know if youre getting too much, too little, or the right amount? What can you look out for just in case you think youmay be overdoing your consumption just a bit?
To understand protein, its probably a good idea to start with macronutrients. There are three macronutrients including fat, protein, and carbohydrates. Basically, the big three that many nutritionists focus on when it comes to a balanced diet. All macronutrients can be found inalmostall food items and each has their own specific roles and functions in the body and supply us with calories or energy.
Protein is one of the three macronutrients and happens to be essential for building muscle mass. These building blocks are composed of amino acids, which are organic compounds made of carbon, hydrogen, nitrogen, oxygen or sulfur. When you consume protein found in ample amounts in the foods we eat its broken down to help fuel muscle mass, which helps metabolism. Per Jessica Crandall, a spokesperson for the Academy of Nutrition and Dietetics, protein also helps the immune system stay strong and it helps you stay full.

While proper protein consumption based on your individual body design is a hugely important part of a well-balanced diet, overconsumption of protein can lead to dangerous side effects.
In these nutrition-crazed times, there is a slew of popular diets that advocate for a higher protein intake including Atkins, the Zone, the Paleo diet, and even the Keto diet which is known as a high-fat diet but also emphasizes increased consumption of protein, while reducing carbohydrates dramatically.
Why are all these diets telling you to eat, eat, and eat more of that good old protein?
As we learned above, protein is an essential part of a healthy diet [and] it helps to build and repair muscle, organs, and bones, while also proving to be helpful with reducing fat, losing weight, increasing satiety, and retaining muscle. All really, really good things!
So, with so many professionals telling you to eat more protein, is there actually too much protein?The short answer is yes.
Too much ofanythingis generally not a great thing. This is why I regularly mention well-balanced in my articles. When it comes to protein overconsumption, its actually somewhat difficult to eat toomuch if youre getting most of it from plant-based proteins such as legumes, nuts, and seeds.The problem arises if youre sourcing protein from animal-based products such as red meat, poultry, eggs, and dairy or if youre consuming extra protein supplements and powders on top of a well-balanced diet.
A 2013 study published in HINDAWI entitled Adverse Effects Associated with Protein Intake above the Recommended Dietary Allowance for Adultsconcluded that extra protein is not used efficiently by the body and may impose a metabolic burden on the bones, kidneys, and liver. On top of that, as referenced to earlier, high-protein/high-meat diets may also be associated with increased risk for coronary heart disease due to intakes of saturated fat and cholesterol or even cancer.
Wheres a good place to start when determining if youre consuming too much protein? Even though every human body is different from age, to weight, to physical activity, to diet, to physiologic design the government has outlined Dietary Reference Intake guidelines 0.8 grams of protein per kilogram of body weight, or 0.36 grams per pound.
Alright, but most of us dont generally weigh our food before consuming, in fact, most of us dont even have a food scale at home, even if we wanted to.So, lets break this down a bit further. In reference to sedentary or non-active adults, you should focus on 56 grams per day for men and 46 grams per day for women. If youre more active, then youll need to adjust accordingly.

It may be easy to identifywhattoo much protein looks like in a diet, but how in the world can you tell if yourebodyis getting too much of it? For those of us that dont have access to nutritionists or dietitians, learning the ins and outs of what protein overconsumption looks and feels like is a great way to keep tabs on that protein intake.
There are actually a handful of symptoms including intestinal discomfort, indigestion, exhaustion, nausea, irritability, and headaches. With that said, these are oftentimes things we experience on a weekly basis due to something bad we ate, stress, or other environmental factors. Therefore, here are some less obvious symptoms that may be telltale signs of protein overconsumption.
A little known fact about protein is thatexcessprotein is usually stored as fat, while the surplus of amino acids is excreted. In the beginning, a high-protein diet may lead to a bit of weight loss, but unfortunately, over time, especially if you consume too many calories while trying to increase your protein intake, that weight will return.
When it comes to constipation, it generally means youre not getting enough fiber in your diet. Diets that are rich in protein, generally also restrict carbohydrates as a balance, and therefore, restrict your fiber intake. Certain studies on high-protein diets have shown that more participants reported constipation. Luckily, theres a simple fix for this! First and foremost increase your fiber and water intake, track your bowel movements, and maybe back off the protein a bit until you smooth things out.
This one is an important symptom to look out for when practicing a high-protein diet. Overconsumption of protein may lead to dehydration, but dehydration will absolutely lead to more unpleasant side effects such as nausea, dizziness, rapid breathing and heartbeat, fatigue, and even fainting.
How does it work?
In an athlete-based study conducted in 2002, it was found that as protein intake increased, hydration levels decreased. This may have something to do with the fact that your body flushes out excess nitrogen with fluids and water [which] can leave you dehydrated even though you may not feel more thirsty than usual.
Alright, this may be a weird one, but its definitely a true one! In fact, the whole bad breath myth has been linked to the keto diet as well and scientists have found the connection may have to do with increased protein consumption in conjunction with reduced carbohydrate intake.Researchers believe this may be part of the metabolic state called ketosis, which produces chemicals that give off an unpleasant fruity smell.
Unfortunately, theres not a whole lot you can do to counteract this effect, as its a natural side-effect of ketosis. With that said, its recommended to double your water intake, brush your teeth more often, and chew gum to counter some of this effect.
When it comes to the relationship between cancer and a high protein diet, its all about thetypeof protein youre consuming.
For those practicing a high-protein diet thats sourced from red meat, youll find not only a higher risk of cancer, but also an increased risk of [other] various health issues. For instance, eating more red and/or processed meat is associated with colorectal, breast, and prostate cancer.
Therefore, whileoverconsumptionof protein doesnt necessarily lead to cancer, choosing the righttypesof protein can help decrease these risks.
