How Much Protein Should You Consume Every Day?

Sure, anyone can look up the recommended dietary allowance (RDA) for the macro-nutrients and vitamins they consume every day. Unfortunately, those numbers, at least for protein, are too low to support maximum healthy muscle growth.

Real-Life Recommendations For Protein Intake

The U.S. government sets the recommended dietary allowance (RDA) for protein, as well as for vitamins, minerals, fiber, fats, and carbohydrates. The RDA for protein starts at a low of around 0.8 grams per kilogram (0.4 grams per pound) of body weight per day for sedentary people, and increases along with increasing levels of activity.

For most people, these protein guidelines are too low. Whether you're an endurance runner or a gym rat, you need more than the average amount to get enough protein to support the recovery and repair of your muscles. In fact, studies overwhelmingly suggest that athletes need more than twice the recommended amount of protein than sedentary people.
If you look at these studies, you can find different and often higher recommendations for grams of protein per unit of body weight. The more intensely you exercise, the greater your protein requirements and the more you should aim for the high end of that range.
Higher protein intake for more active people helps repair tissue and replenish amino acids used for fuel during intensive activity. Resistance training stimulates muscle synthesis (growth), but it also increases muscle breakdown—so much so that when you exercise in a fasted stated, you can break down more protein than your body is building, resulting in muscle loss. Consuming protein immediately after working out can help you balance muscle breakdown and muscle growth. One specific protein, the amino acid leucine, stimulates the cellular pathway responsible for muscle growth.

You May Need More Protein If..

Older adults can also benefit from higher protein consumption. As we age, our bodies become less efficient at using this macro-nutrient. Over time, this protein deficiency can lead to decreased strength and loss of both muscle mass and mobility. Staying physically active and eating a minimum of 1.2 grams of protein per kilogram of body weight can help you stay in fighting shape well into your golden years.
Vegetarians and vegans should also pay close attention to how much and what kinds of protein they consume. Except for soy and quinoa, most vegetarian and vegan sources of protein are considered incomplete because they don't contain all nine essential amino acids necessary for protein synthesis. A daily protein intake of 1.5-2.0 grams per kilogram of body weight along with a varied diet of legumes, grains, and beans, vegans and vegetarians can take in enough essential amino acids in their diet to build and repair muscle tissue. 

You may have heard rumors that eating too much protein can cause kidney damage, liver failure, or osteoporosis. In fact, there is no evidence that a reasonably high protein intake has any negative effect in healthy individuals.

Protein And Weight Loss

Higher-protein diets may help you lose weight, too. Studies have shown that consuming protein can increase feelings of satiety, which helps your body composition by reducing your urge to snack. What's more, since your body must work extra hard to digest protein, it can also increase the number of calories you burn. Consuming 1.2-1.6 grams of protein per kilogram of body weight can also help you maintain muscle mass even as you reduce your overall calorie intake.

Does The Timing Of Your Protein Intake Matter?

Bodybuilders are always trying to figure out what time during the day (or night) is best for consuming protein. Should you take it before, during, or after exercise? Should it be the first thing you eat every day, or the last thing? It's really a question of how much protein you consume in a 24-hour period—not exactly when you consume it.
Whether you shovel down a dozen scrambled eggs in the morning, slam a protein shake immediately post-workout, or eat a tub of cottage cheese before bed, your top priority should always be to make sure you're consuming your daily protein quota, as outlined above.

The rate of muscle protein synthesis remains elevated for 3-5 hours after you consume protein. By consuming about 20 grams of protein 3-4 times per day, you can continuously stimulate protein synthesis while suppressing protein breakdown. Studies have also shown no real benefit to consuming more than 20 grams of protein at any meal.
That's not to say that consuming more protein than that is a complete waste. While the extra protein won't increase rates of protein synthesis, it can help minimize muscle breakdown, be stored in your body's "amino-acid pool" for later use, or serve as a fuel source during longer-duration, higher-intensity workouts.
