Everything about Protein Intake - How Much Protein per day?



The precise quantity of protein you require is determined by a variety of factors, including your activity level, age, muscle mass, and general health.


Protein is one of the most vital nutrients. Its deficiency will have an impact on your health and body composition.


However, ideas on how much protein you require to differ.


The majority of recognized nutritional organizations advocate moderate protein consumption.


The DRI (Dietary Reference Intake) for protein is 0.36 grams per pound (0.8 grams per kg) of body weight.


This equates to 54 grams per day for a 150-pound inactive individual or 65 grams per day for a 180-pound sedentary individual:


This quantity may be sufficient to prevent deficiency, but the amount you require is determined by a variety of factors, including your exercise level, age, muscle mass, physique objectives, and general health.


This article investigates the appropriate protein quantities and how lifestyle factors such as weight reduction, muscle growth, and activity levels play a role.



What exactly is protein, and why is it so important?


Proteins are the primary structural components of your body. They are employed in the production of muscles, tendons, organs, and skin, as well as enzymes, hormones, neurotransmitters, and other compounds that perform a variety of critical activities.


Proteins are made up of smaller molecules known as amino acids, which are linked together like beads on a string. These connected amino acids combine to generate lengthy protein chains that fold into complicated forms.


Some of these amino acids are produced by your body, while others, known as essential amino acids, must be obtained from the diet.



Protein is about more than just amount; it is also about quality.


In general, animal protein has all the required amino acids in the proper ratios for you to fully use them. This makes sense because animal tissues are identical to your own.


If you eat animal products like meat, fish, eggs, or dairy on a daily basis, you're probably receiving enough protein.


However, if you do not consume animal products, it may be more difficult to obtain all of the protein and critical amino acids your body requires. If you eat a plant-based diet, you might be interested in this post on the 17 greatest vegan protein sources.


Few people require protein supplements, although sportsmen and bodybuilders can benefit from them.



Can help you lose weight and keep it off.

When it comes to reducing weight, protein is essential.


To lose weight, you need to consume fewer calories than you burn.


Protein consumption appears to improve calorie expenditure via increasing metabolic rate (calories out) and decreasing hunger (calories in).


Protein consumption of 25-30% of total daily calories has been demonstrated to increase metabolism by up to 80-100 calories per day when compared to lower protein diets.


However, protein's most essential contribution to weight loss is believed to be its capacity to suppress hunger, resulting in a decrease in calorie consumption. Protein keeps you fuller longer than fat or carbohydrates.


In one research of obese males, taking 25% of calories from protein boosted sensations of fullness while decreasing late-night snacking urges and compulsive food thoughts by 50% and 60%, respectively.


Another 12-week study found that increasing protein consumption to 30% of calories resulted in 441 fewer calories consumed per day and a loss of 11 pounds (5 kg) by merely adding extra protein to their diet.


Furthermore, protein can help prevent weight gain as well as aid in weight reduction.


A minor increase in protein from 15% to 18% of calories decreased the number of fat patients regained after losing weight by 50% in one study.


A high-protein diet also aids in the development and maintenance of muscle mass, which burns a modest amount of calories continuously.


Eating extra protein helps any weight reduction regimen — high carb, low carb, or something in between — much easier to stick to.


According to the research described above, a protein consumption of roughly 30% of total calories may be ideal for weight reduction. For a 2,000-calorie diet, this equates to 150 grams per day.


You can figure it out by multiplying your daily calorie consumption by 0.075.



Can assist you in gaining muscle and strength


Muscles are mostly composed of protein.


Muscles, like other biological tissues, are dynamic, continually being torn down and replaced.


To grow muscle, your body must produce more muscle protein than it consumes.


In other words, your body must have a net positive protein balance — often known as nitrogen balance since protein is heavy in nitrogen.


As a result, those who want to grow muscle consume more protein and exercise more. A higher protein intake can aid in the development of muscle and strength.


Meanwhile, people who wish to keep the muscle they've created may need to boost their protein consumption when shedding body fat, because a high protein intake might assist prevent muscle loss that happens when dieting.


When it comes to muscle mass, studies normally focus on the daily grams of protein per kilogram or pound of body weight rather than the percentage of calories coming from protein.


One gram of protein per pound (2.2 grams per kg) of body weight is frequent advice for muscle growth.


Other researchers believe that protein needs to be at least 0.7 grams per pound (1.6 grams per kilogram) of body weight.


Numerous studies have attempted to discover the appropriate quantity of protein for muscle building, but the results have been mixed.


Some research demonstrates that eating more than 0.8 grams of protein per pound (1.8 grams per kg) provides little advantage, but others show that eating slightly more than 1 gram of protein per pound (2.2 grams per kg) is optimum.


Though specific statistics are difficult to establish because of contradictory study results, 0.7-1 gram per pound (1.6-2.2 grams per kg) of body weight appears to be an acceptable approximation.


If you have a lot of body fat, choosing your lean mass or goal weight instead of your total body weight is a smart option, because it's your lean mass that dictates how much protein you need.



Pregnancy and protein

The body requires additional protein during pregnancy for tissue development and growth. Protein is beneficial to both the mother and the infant.


One study's authors recommend that pregnant women ingest 0.55-0.69 grams of protein per pound (1.2-1.52 grams per kg) every day.


Experts recommend ingesting an additional 0.55 grams of protein per pound (1.1 grams per kg) every day throughout pregnancy.


The daily protein allowance while nursing is 0.59 grams per pound (1.3 grams per kg), plus an additional 25 grams.


The best method to get any vitamin is through dietary sources. Sources to consider include:

  • lentils, peas, and beans

  • eggs

  • flesh that is lean

  • items made from milk

  • seeds and nuts

  • tofu



Fish and seafood are other excellent sources.

Choose fish that are low in mercury and high in omega-3 fatty acids during pregnancy and breastfeeding, such as salmon, sardines, and anchovies.


However, avoid species with high mercury levels, such as swordfish, tilefish, and king mackerel.


Ideally, you should obtain 100% of your protein from your diet. In such circumstances, your doctor may advise you to take supplements. However, there are no recommendations for protein supplementation during pregnancy.


Other factors that may raise protein requirements

People who are physically active require more protein than those who are sedentary, regardless of muscle mass or physique aspirations.


If your profession requires a lot of walking, running, swimming, or other forms of activity, you should eat extra protein.


Endurance athletes require a lot of protein — around 0.5-0.65 grams per pound (1.2-1.4 grams per kg) of body weight.


Protein requirements for older persons are up to 50% greater than the DRI, or roughly 0.45-0.6 grams per pound (1-1.3 grams per kg) of body weight.


This can aid in the prevention of osteoporosis and sarcopenia, both of which are serious issues among the elderly.


People who are healing from injuries may also require additional protein.



Is there anything wrong with protein?


Protein has been wrongfully blamed for a variety of health issues.


Some individuals assume that a high protein diet might induce kidney damage and osteoporosis, although scientific evidence refutes this.


Though protein restriction is beneficial for patients who already have renal issues, there is no evidence that protein can harm the kidneys in healthy people.


In fact, eating more protein may help decrease blood pressure and battle diabetes, both of which are major risk factors for kidney disease.


Protein's presumed negative effects on renal function are offset by its favorable effects on these risk variables.


Some people believe that eating too much protein causes osteoporosis, yet evidence suggests that it can help avoid the condition.


Overall, there is no evidence that moderate protein consumption has any negative consequences on healthy adults attempting to enhance their health.



How to Include More Protein in Your Diet


Meats, fish, eggs, and dairy products are the finest sources of protein because they include all of the necessary amino acids that your body requires.


Quinoa, legumes, and nuts are among the plants that are high in protein.


Most people, however, do not need to watch their protein consumption.


If you're wanting to stay healthy, consuming excellent protein sources with most of your meals, together with nutritious plant foods, should bring your consumption to an appropriate level.


What "protein grams" truly imply

This is a very common source of confusion.


The term "grams of protein" in nutrition science refers to the number of grams of the macronutrient protein, not the number of grams of a protein-containing item such as meat or eggs.


A serving of beef weighs 226 grams but provides just 61 grams of protein. A big egg weighs 46 grams but contains only 6 grams of protein.



What about the ordinary person?

If you're at a healthy weight, don't lift weights, and don't do much activity, aiming for 0.36-0.6 grams per pound (0.8-1.3 grams per kg) is a good starting point.


This equates to:

  • The average guy consumes 56-91 grams per day.

  • The average female consumes 46-75 grams per day.

  • Nonetheless, considering that there is little evidence of risk and strong evidence of benefit, most individuals would be wise to consume more protein rather than less.
