Can Too Much Protein Be Harmful
The short answer is yes. As with most things in life, there can be too much of a good thing and if you eat too much protein, there may be a price to pay. For example, people that eat very high protein diets have a higher risk of kidney stones. Also a high protein diet that contains lots of red meat and higher amounts of saturated fat might lead to a higher risk of heart disease and colon cancer, while another high protein diet rich in plant-based proteins may not carry similar risks.
What Is Protein How Much You Need Benefits Sources More
Protein needs no introduction. You likely already know it as one of the three major macronutrients that make up your diet .
There are hundreds of products from supplements to energy bars designed to make it easy to get your protein fix. There are even entire diets based on upping your protein intake, such as the Atkins diet or the paleo diet.
But what is protein all about anyway? And what benefits does it offer the body?
Dig in here.
Protein Foods And The Planet
To give you an idea, this scorecard from the World Resources Institute illustrates the differing GHG emissions per gram of protein from both animal and plant-based protein foods. Making just one pound of lamb generates five times more GHGs than making a pound of chicken and around 30 times more than making a pound of lentils. In the U.S. alone, beef accounts for 36% of all food-related GHG emissions. Beyond emissions, its also important to note that food production places an enormous demand upon our natural resources, as agriculture is a major contributor to deforestation, species extinction, and freshwater depletion and contamination.

The Amino Acid Profile Varies Between Plant And Animal Proteins
When eaten, protein is broken down into amino acids.
Proteins and amino acids are used for almost every metabolic process in the body.
However, different proteins can vary greatly in the types of amino acids they contain.
While animal proteins tend to contain a good balance of all the amino acids that we need, some plant proteins are low in certain amino acids.
For example, some key plant proteins are often low in methionine, tryptophan, lycine and isoleucine.
All proteins are made up of amino acids, although the amount and type of each amino acid varies based on the protein source.
How Much Protein Do You Need Per Day
As with most things in nutrition, theres no simple answer. Your ideal intake of calories and protein depends on your health, body composition, main goal, and the type, intensity, duration, and frequency of your physical activity. And even taking all this into account, youll end up with a starting number, which youll need to adjust through self-experimentation.
Tip: Calculating your caloric needs
Your height, weight, age, and level of physical activity all contribute to your caloric needs. There are many calorie calculators out there, but the NIH Body Weight Planner stands out. It has been tested and validated against real-world data and can estimate the number of calories you need to reach then maintain a specific weight.
Calorie-wise, there are only three types of diets:
Daily protein requirements are expressed in grams, either per kilogram of body weight or per pound of body weight . Ranges in the table below reflect known individual variances.
Maintenance: eucaloric diet | Muscle gain: eucaloric diet or hypercaloric diet | Fat loss: hypocaloric diet | * Grams per kilogram of body weight
Also, note that
Protein intake should be based on body weight, not on caloric intake.
Most studies have looked at dosages up to 1.5 g/kg only a few have looked at dosages as high as 2.23.3 g/kg. However, in healthy people, even those higher dosages dont seem to have negative effects.
Tip: Calculating your protein needs
How To Calculate Your Recommended Protein Intake
The Recommended Dietary Allowance is 0.8 grams of protein per kilogram of body weight. To maintain nutritional balance, the U.S. Department of Agriculture’s MyPlate guidelines recommends protein make up about a quarter of your plate.
To calculate the target number of grams of protein you should eat each day, take your body weight in pounds and multiply it by 0.36. The result should get you within the recommendation to source 10 to 35 percent of your daily total calories from protein. Usually that means having some kind of dairy at each meal plus a piece of meat the size of a deck of cards thats 3 ounces or the equivalent amount of plant-based protein at lunch and dinner.
Keep in mind that these recommendations may change depending on age and health. The recommendation changes for athletes, too. People who exercise frequently or are training for a race need to increase their protein intake to between 1.1 and 1.7 g per kg of body weight daily. Anything over 2 g per kg of weight is considered excessive.
What Happens If You Eat Too Much Protein
If youre wondering what happens if you eat too much protein, heres the scoop. Eating too much protein is inadvisable as it can cause colorectal cancer, heart disease, kidney problems, and osteoporosis. Indulging in too much of it, even when following a low-carb high-protein diet, can easily increase your fat stores and risk nutrient deficiencies.
A secondary problem exists when we eat too much protein. Doing so excludes other vital nutrients, fiber, heart-healthy fats, and complex carbohydrates. As we eat too much of one thing, we end up excluding other things. A well-balanced diet at every meal contributes to improving overall health and lowering your chances of developing diseases.

How Much Protein Do You Need
Not everyone has the same protein requirement. It depends on many factors, including body weight, muscle mass, physical activity and age.
Arguably, body weight is the most important determinant of protein requirements. As a result, recommendations are usually presented as grams for each pound or kilogram of body weight.
The recommended daily allowance is 0.4 grams of protein for each pound of body weight . Scientist estimate this should be enough for most people.
This translates to 66 grams of protein per day for an adult weighing 165 pounds .
For athletes, the American College of Sports Medicine recommends a daily protein intake ranging from 0.5 to 0.6 grams for each pound of body weight , which should be enough for muscle maintenance and training recovery .
However, scientists dont agree how much is enough. The International Society of Sports Nutritions daily recommendation is 0.9 grams of protein per pound of body weight for athletes .
Just like athletes, older adults also seem to have higher protein requirements.
While the RDA is currently the same for old and young adults, studies indicate it is underestimated and should be raised to 0.5 to 0.7 grams per pound of body weight for older people .
Simply put, if you are older or physically active, your daily protein requirements are probably higher than the current RDA of 0.4 grams per pound of body weight .
The richest sources of protein include fish, meat, eggs, dairy products and legumes.

Can You Eat Too Much Protein
For most of us, our daily protein requirements are easily achieved by a healthy, balanced diet. The Department of Health advises adults to avoid consuming more than twice the recommended daily intake of protein . This is because, in the long term, consuming too much protein might lead to health issues such as an increased risk of osteoporosis and a worsening of an existing kidney problem. However, research in this area is mixed and it is likely that other factors may influence outcome, such as whether the protein is of animal or vegetable origin and how balanced the diet is in terms of vitamins and minerals.
One of the main issues with our Western diet is that often, our breakfasts and lunches are low in protein but high in carbohydrates, with a protein-packed evening meal. It is better to aim to spread your protein intake out throughout the day. Try our suggestions for high protein breakfasts, high protein lunches and high protein dinners.

Its All About The Protein Package
When we eat foods for protein, we also eat everything that comes alongside it: the different fats, fiber, sodium, and more. Its this protein package thats likely to make a difference for health.
The table below shows a sample of food packages sorted by protein content, alongside a range of components that come with it.
To call out a few examples:
- A 4-ounce broiled sirloin steak is a great source of proteinabout 33 grams worth. But it also delivers about 5 grams of saturated fat.
- A 4-ounce ham steak with 22 grams of protein has only 1.6 grams of saturated fat, but its loaded with 1,500 milligrams worth of sodium.
- 4 ounces of grilled sockeye salmon has about 30 grams of protein, naturally low in sodium, and contains just over 1 gram of saturated fat. Salmon and other fatty fish are also excellent sources of omega-3 fats, a type of fat thats especially good for the heart.
- A cup of cooked lentils provides about 18 grams of protein and 15 grams of fiber, and it has virtually no saturated fat or sodium.
Optimal Daily Protein Intake For Healthy Sedentary Adults
For adults, the US Recommended Dietary Allowance for protein is 0.8 g/kg. However, a more appropriate statistical analysis of the data used to establish the RDA suggests this number should be higher: 1.0 g/kg.
Note that, contrary to popular belief, the RDA doesnt represent an ideal intake. Instead, it represents the minimum intake needed to prevent malnutrition. Unfortunately, the RDA for protein was determined from nitrogen balance studies, which require that people eat experimental diets for weeks before measurements are taken. This provides ample time for the body to adapt to low protein intakes by down-regulating processes that are not necessary for survival but are necessary for optimal health, such as protein turnover and immune function.
An alternative method for determining protein requirements, called the Indicator Amino Acid Oxidation technique, overcomes many of the shortcomings of nitrogen balance studies. Notably, it allows for the assessment of protein requirements within 24 hours, thereby not leaving the body enough time to adapt. Studies using the IAAO method have suggested that about 1.2 g/kg is a more appropriate RDA for healthy young men, older men, and older women.
Further evidence that the current RDA for protein is not sufficient comes from a randomized controlled trial that confined healthy, sedentary adults to a metabolic ward for eight weeks. The participants were randomized into three groups:
