Muscle Protein Synthesis Vs Muscle Protein Breakdown
Amino acids are also used for muscle protein synthesis – the process of repairing and maintaining muscles after intense use.
When muscles are used during exercise or strenuous activity, it creates micro-tears and leads to muscle protein breakdown . Amino acids are then shuttled to your muscles to start repairing this damage and synthesizing new tissue to replace the damaged ones.
This process doesn’t automatically lead to bigger muscles , but it can make your muscles stronger or adapt to the type of training that caused the tears in the first place .
MPS is why protein, and strength training, in particular, are so essential for maintaining and building lean body mass.
What Happens When You Overeat Protein
Although you need to consume a lot of protein to build muscle, you do not want to overconsume protein.
Most doctors suggest that a healthy adult can have a protein intake of up to 2 grams per 1 kg of body weight without side effects, and people who work out frequently, such as athletes, may consume up to 3.5g per kg without any problems.
Eating more than 2g of protein per kg of body weight daily could lead to health issues, such as weight gain, nausea, fatigue, heart disease, and kidney or liver issues.
While protein is vital for building muscles, it is not the only nutrient you need. You also need to get enough carbohydrates and calories. Ignoring these nutrients would do more harm than good and may cause serious health complications in the future.
In addition, ensure to drink lots of water. Besides helping to prevent dehydration, water can help your body remove excess protein.
So Does It Matter If You Get Your Protein From Powder Or From Food
Whether or not you need protein powder really depends on what your diet consists of already, Gonzalez says. Most people can indeed get enough protein, powder-free. For the average healthy person whos pretty athletic and eating a balanced, diverse diet, theyre probably getting enough protein from their food already, Beth Kitchin, Ph.D., R.D.N., assistant professor in the UAB Department of Nutrition Sciences, tells SELF.
It is absolutely possible to consume adequate protein from real food, adds Linsenmeyer. Meat, fish, poultry, eggs, dairy, beans, lentils, soy products, nuts, seeds, whole grains all provide dietary protein.
Real food also has a couple advantages over powder. It can certainly cost less, given some protein powders can cost you a pretty penny.
Now, lets say youre finding it hard to get enough protein from food. Thats where protein powder can really come in handy. If youre not getting enough protein already, a protein supplement can be beneficial, Gonzalez says. Protein powders can be a great way to add more protein into the diet if you cant meet those needs through just food, Ansari agrees.

How To Calculate Your Protein Requirements For Muscle Mass
If you want to calculate how much protein you need to build muscle mass, there are a few approaches you can take.
150lbs / 2.2 lbs/kg = 68.2 kg bodyweight x 1.2 g/kg protein = 82 grams protein per day
2000 calories x 0.30 = 500 calories from protein / 4 calories per gram = 125 grams protein per day

Why It Takes More Than Just Protein To Build Muscle
A lot of people who are trying to bulk up are also trying to lose body fat at the same time. But sometimes, the approaches they use to meet those goals are at odds with each other. Theyll take in plenty of protein, which, when coupled with a strength training routine, should lead to more lean mass. But they may also cut their total calories back too far in an effort to get shredded.
That can be a problem. If you cut your calories too much, some of the protein that you eat is going to be burned for fuel rather than being used to support muscle development. So, to effectively build muscle mass, you want to ensure that you have enough calories to support your activity and the right balance of nutrients, too.
How Long Does It Take To Build Muscle Can I Build Muscle Quickly
Muscle building takes time, and youll need a proper program tailored to your lifestyle and fitness level. Remember that rest and good nutrition will affect your results.
If done right, you will feel stronger in the 6th to 8th week of your lifting program. These are neuro-muscular gains you are feeling: your body will adapt to the movements and the feeling of the weights, and your muscles become more coordinated. Although you might not see physical gains, your brain-to-muscle signals are becoming more efficient!
Then, around the 12th week of your training, if you are resting and eating well, you will start to notice your muscles growing. This is when you may feel your clothes fitting differently.

New Research Shows That You Don’t Need A High Protein Diet
A recent 2021 randomized control trial published in the American Journal of Physiology-Endocrinology and Metabolism had 50 overweight middle-aged men and women start resistance training for 10 weeks while being assigned either moderate protein intake or high protein intake . The goal was to determine if high protein intake would increase resistance training-induced changes in muscle strength and body composition compared to moderate protein intake.
Participants in the moderate intake group ate three ounces of beef immediately after exercise while the high protein group ate six ounces . In addition to that, participants were provided beef isolate protein powder to drink one to two hours before bed. Those in the moderate protein group drank 15 grams worth of protein and the high group consumed 30 grams. When it came to exercise, all participants did whole-body resistance training 3 days per week.
After the 10 weeks were up, participants had their muscle strength, performance, and body composition compared to their baselines . The results found that muscle strength and performance were not different between moderate and high protein groups. Total body mass for those in the moderate protein group increased by 1.3 kg and by 1.5 kg in the high protein group, which isnt a significant difference.
When you take in more protein than your body needs, it gets stored as fat, just as other excess calories from other macros, and you excrete the unneeded amino acids in urine.
How Much Protein To Build Muscle Ask An Rd
The main building blocks of your body,protein is used to repair and maintain your body tissues including muscle.
If your goal is to build muscle, then its important that youre getting the right amount of protein, as well as the right amounts of the other macronutrients, carbohydrates and fats.
The general strategy for calculating the minimum amount of protein that you need is 0.36 grams of protein per pound that you weigh. In a 165-pound adult, thats about 60 grams of protein per day.
But thats just the minimum recommended daily allowance .
You might be wondering if the minimum amount of protein recommended is enough to actually build more muscle. Below, well explore just how much protein you should consume per day to build muscle .

Get Some Healthy Fats
Dietary fat is sometimes underappreciated by some athletes. Like carbs, fats may have an undeserved bad reputation. Small amounts of the right kinds of fats are very important. Thats because certain fatty acids, the building blocks of dietary fats, are essential because the body cant make them. Fatty acids are a vital structural component of every cell membrane, including muscle cells. The body relies on fat to fuel moderate intensity, longer-term exercise. Thats just the type of exercise that might be coupled with a strength-training regimen to build mass and lose body fat.
Good sources of fatty acids:
Potential Side Effects Of Protein Shakes
What happens if you drink protein shakes without working out? Are there any side effects?
Protein shakes can cause side effects. However, these issues dont occur simply from drinking protein shakes without working out. If you experience any side effects, youd likely experience them if you did work out.
Some potential side effects of drinking protein shakes include:
- Digestive discomfort. Some protein powders have sweeteners such as sucralose, acesulfame potassium, and aspartame. These can cause gas, bloating, or stomach cramps in certain individuals. Adding high-fiber fruits and veggies to your protein shake can also cause digestive discomfort.
- Breakouts. Some studies show that people can experience breakouts from consuming dairy, though researchers say this information should be taken cautiously due to biases throughout the studies. But if you notice an increase in skin issues after introducing protein shakes that include dairy , you may not be able to tolerate them.
- Headaches. Low-quality protein powders and pre-bottled protein shakes made with low-quality ingredients can be contaminated with toxic metals like lead and arsenic. Consuming too much of these can cause headaches.

How Did We Calculate Your Protein Intake
Bodybuilding.com’s protein calculator starts with the Mifflin St. Jeor equation, which is considered by our nutritionists and dieticians to be the “gold standard” of calorie calculators. Here’s how it works:
Calculate basal metabolic rate , or the calories your body burns simply by being alive. For men: 10 x weight + 6.25 x height â 5 x age + 5 For women: 10 x weight + 6.25 x height â 5 x age -161
Then, this BMR count is multiplied, depending on your activity level:
Sedentary = 1.2
Why Is Protein Important For Building Muscle
Protein is made up of amino acids that act as building blocks for cells and tissues in the body. There are 20 amino acids that combine to form proteins.
While some can be synthesized by the human body, others cannot. The nine amino acids that the body cannot make are called essential amino acids. These must be obtained through diet.
When a person eats protein, it is digested and broken down into amino acids, which are involved in many processes in the body, including tissue growth and repair, immune function, and energy production.
Like other body tissues, are continuously broken down and rebuilt. In order to build muscle, a person must consume more protein than what is broken down. This is often referred to as a net positive nitrogen balance, as protein is high in nitrogen.
If a person is not consuming adequate amounts of protein, their body tends to break down muscle to provide the body with the amino acids needed to support body functions and preserve more important tissues. Over time, this can lead to decreased muscle mass and strength.
Lastly, the body uses amino acids for muscle protein synthesis , the primary driver of muscle repair, recovery, and growth after strenuous exercises.
2020-2025 Dietary Guidelines for Americans , most healthy adults over 19 years old should get between 10-35% of their daily calories from protein. One gram of protein provides 4 calories.
Here is what the latest research says.

How Do You Build Physical Strength
Strength training, also known as resistance training, is the main form of exercise you want to focus on to build muscle. These exercises include weightlifting or bodyweight training to improve your strength and strength endurance. When you are training to increase strength or gain muscle, however, there are two things you need to make sure you are doing in your training to initiate the physiological change for hypertrophy :
This is a good thing! These stresses you apply to the muscle will cause damage to the muscle fibers, causing micro-tears, which send signals for the cells to regrow back stronger and bigger!
And remember, growth happens with rest, so make sure to follow a well-designed program that gives you a day to rest the muscle you just worked so it has a chance to recover and grow. To see continual improvements from strength training, you should gradually increase the weight and reps.
Heres How Much Protein Most People Need
If youre downing protein shakes, youre most likely doing it because you think you need more protein in your life. So lets first talk about how much protein you in fact need.
The amount of protein you should be getting each day varies based on factors like age, sex, health, and activity level, according to the U.S. National Library of Medicine. But for a baseline we can use the recommended daily allowance , which is based on the average amount of protein determined to meet the nutrient requirements of 97% to 98% of healthy individuals: 0.8 grams of protein per kilogram of body weight per day.
That means that a 150-pound person needs around 54 grams of protein per day, while a 200- pound person needs around 72 grams of protein a day. Based on those guidelines, most people already get enough protein from their diets, per the U.S. National Library of Medicine. If you have roughly zero idea how much protein you typically eat per day, here are a few examples of the amounts you can find in some common foods: a 4-ounce chicken breast has 27 grams, a cup of lentils has 17 grams, two large eggs have 12 grams, and two tablespoons of peanut butter have 7 grams.

How Much Do I Need To Eat To Gain Muscle Clearly Explained
In order to gain muscle mass, most people need around 20 calories per pound of body weight. This means that if you want to build muscle, you need to eat around 2000 calories a day.
This is a lot of calories, but its not as bad as it sounds. The problem is that most people dont eat enough of them, so they end up eating more than they need, which can lead to weight gain.
More Protein Does Not Necessarily Mean More Muscle Growth
Interviewer: Stacey Wing-Gaia is a registered dietician and the Director of Sport Nutrition program at the University of Utah. Let’s talk protein today. Go on the internet and you surf for about 10 seconds and you’re confused. How much protein do I really need?
Stacey Wing-Gaia: I’ll tell you as a dietician usually the first nutrient that people are concerned about, that they always ask is protein. How do I get more protein? I can tell you that it’s very rare that someone does not get enough protein.
Interviewer: That’s interesting. So how much is that?
Stacey Wing-Gaia: Maximum amount would be about 1 gram per pound of body weight. So that would be a really very upper threshold that maybe I may have an adolescent boy that’s going through teenage years and growth spurts or maybe someone with cancer that needed to put on more muscle. But most people don’t need that much, probably more like a half a gram to maybe .7, .8 grams per body weight.
Interviewer: That’s interesting because on the internet, you know I go the the gym I do some strength training, I do some aerobics stuff and it says if lifting weights and you want to gain weight you should get a gram per pound of body weight. You’re saying that’s not necessarily the case?
Interviewer: So interesting so it’s not so much about the protein as it is about overall calories in that instance of wanting to maybe put on some more muscle mass?
Stacey Wing-Gaia: Yes, definitely.
