Today's guest post comes from the good folks at Examine.com, a great website to which I refer often for unbiased information on supplements and nutrition. Enjoy! - EC

Protein is everyone’s favorite macronutrient. Why?

1. The media doesn’t go crazy over it like it does over fats and carbs.
2. It’s been proven to help build muscle.
3. Protein shakes are as well-known (and used) as energy drinks.

Although there is the occasional study or media report that suggests too much protein can cause organ damage or increase cancer risks, these concerns are typically overblown. People with certain medical conditions may exacerbate their symptoms by eating too much protein, but the most likely damage that excessive protein will do to a health person is lighten their wallet.

The most frequent question posted online about protein consumption is a simple one: what’s the optimal daily protein intake?

Protein intake recommendations

The Examine.com page on recommended protein intake breaks down the existing research on protein intake. Recommended daily protein intake depends largely on health goals and activity level:

0.8 g/kg body weight (0.36 g/lb) if your weight is stable and you don’t exercise
1.0-1.5 g/kg (0.45-0.68 g/lb) if your goal is weight loss or you’re moderately active
1.5-2.2 g/kg (0.68-1 g/lb) if your goal is weight loss and you’re physically active

People who are obese should calculate their daily protein intake based on their goal weight, not existing body weight (in order to not ingest too many calories).

At least one gram of protein per kilogram of body weight a day is sufficient for an athlete. Studies show that there isn’t a significant practical difference between 1.5 to 2.2 g/kg(0.68 – 1g/lb) of daily protein intake. For a 180 lb athlete, this is 122 to 180 grams of protein (the difference being the equivalent of about two chicken breasts).

Protein intake and bulking

Bulking and weight gain doesn’t necessarily require increased protein intake. Muscle growth is affected by protein availability and protein elimination rates, or how fast protein is used up in metabolic reactions.

The more calories the body has to work with, the more efficiently it utilizes protein because fewer amino acids are converted into glucose. However, increasing protein intake may not be necessary during a bulk, because the added calories are contributing toward more efficient protein use. Ingesting protein also increases protein signaling, which is necessary for muscle growth. That being said, exercise has a similar effect, which means working hard in the gym could render the extra signaling effect from additional protein intake negligible during a bulk.

Excessive protein intake

There is enough evidence to support the safety of 0.8-1.2g/kg (about .5g/lb) of protein per day. Although there is little evidence to suggest excessive protein intake may be harmful, there are also not many studies on the topic.

People with kidney or liver damage should consult their doctor when determining how much protein to eat. Too much protein can overwork previously damaged organs and can exacerbate symptoms. Otherwise healthy people can eat an extra chicken breast or opt for another protein shake without worrying about their health.

Supplementing to replace protein intake

People who cannot eat enough protein due to finances, diet preferences, or motivation often turn to supplementation to avoid eating yet another can of tuna.

The two best supplementation options for conserving muscle mass during caloric restriction are leucine and β-Hydroxy β-Methylbutyrate (HMB). Leucine is the primary amino acid in protein that’s primarily responsible for signaling muscle tissue to grow. HMB, leucine’s metabolite, also helps preserve lean mass and reduces the rate of catabolism. Leucine turns into HMB at a 5% rate, so one gram of HMB is equivalent to about 20 grams of leucine.

Supplementation should only be used if dietary changes cannot be made to meet your protein requirements. It is however, worth noting that consuming protein in the form of actual food can yield benefits that supplementation can’t. But if dietary changes are not practical, supplementation can help improve muscle growth and minimize muscle loss.

Ideal sources of protein

As long as the protein is coming from a bioavailable source (not pure gelatin) and contains all the essential amino acids, it doesn’t matter what food it’s coming from.

Protein sources do matter in the context of the overall diet. For example, eating fatty tuna means there will be less room in the diet for other calories, since the fat in the tuna means the protein source contains more calories overall. Prioritizing lean meats can help keep calorie count low, or free up some calories for treats.

Worrying about the differences between whey protein vs casein protein vs hemp protein (and other protein powders) is an exercise in futility. The primary distinction between them is how you find their taste, and potentially their consistency (as casein is gel-like, it’s usually more applicable in baking situations). The slight difference in micronutrients is literally not worth the headache.

The bottom line on protein

The media and supplement industry overcomplicate recommended protein intake because it generates clicks, creates dogma, and helps sell product. As long as you’re eating a balanced diet, get plenty of sleep, and exercise frequently, one gram of protein per kilogram to pound of body a day is plenty for your muscle and health-related goals. Yes, you read that correctly: 1 gram per kg to lb is likely sufficient. That means if you're 200lbs, targeting between 90 to 200g of protein is fine. People tend to overthink how much protein they need, and unless you are on a diet or an endurance athlete, you don't actually need as much protein as is often suggested. That said, having more is also likely not detrimental.

It's that time of the week again: Greg Robins is here to throw some tips your way to lose fat, gain muscle, get strong, and take over the world.  It's also quite fitting that Greg be our guest contributor on 9/11 in light of his military background.  With that in mind, for every Tweet or Facebook Share (both can be done in the top left of this page) this post gets by the end of the day on Wednesday, I'll donate $0.10 to the Wounded Warrior Project.  Thank you very much to all of you who have served our country.

Now, on to Greg's tips...

1. Be careful not to pair competing exercises.

When you set up your own strength training programs, exercise selection is the most commonly recognized variable; they think about it before they consider a number of other factors. I often advise people to look deeper than simply the strength exercises they are choosing. Instead, many would be better served to evaluate things like sets and reps schemes and total volume week to week while keeping the same movements in their approach longer. This aside, strength exercise selection must be considered at some point, and one rookie mistake is pairing two exercises that directly compete against one another.

Exercises may compete in a variety of ways. For example, pairing two exercises that are heavily grip dependent, such as rows and dumbbell lunges, provides an unneeded challenge to maintain grip strength. A better suggestion would be to keep the rows, but go to a single-leg exercise that doesn't require as much grip work:

Another common example is pairing prone bridge variations with pushing exercises, as the shoulder fatigue will often take away from the ability to maintain good posture in the prone bridge. Take a look at how you have set up your strength and conditioning programs and eliminate pairings that do not allow you to give a full effort to each exercise. It’s easily fixed by subbing in exercise pairings that are direct opposites (e.g., rows with presses) or by pairing strength exercises with mobility drills.

2. Choose jumps and throws wisely for those with elbow and knee pain.

I am an advocate of placing a small amount of “explosive” training at the beginning of both competitive athletes and general fitness clients' programs. Performing an explosive movement prior to resistance training helps to prime the nervous system for the day's training. Additionally, it helps mentally gear people up to lift heavy stuff!

However, many people deal with nagging elbow and knee pain, which can be problematic when coupled with many of the common exercises utilized in this capacity. In some cases, a person may need to forgo these types of movements altogether while we work to alleviate the causes of such problems. For many, though, explosive movements can still be incorporated if appropriate exercises are selected. Limit jumping variations to those with the least amount of deceleration. Work with low level box jumps, and avoid options like broad jumps and depth jump variations. Another great option is to utilize jumps up an inclined surface, like a hill. Furthermore, kettlebell swings present us with an excellent joint friendly option to work the lower extremities in a low impact, explosive fashion.

Lastly, medicine ball exercises can present problems for those with elbow pain. When presented with these issues, stick to throws that do not call for violent extension of the elbow joint. These include overhead stomps done with straight arms, overhead throws done the same way, and scoop toss variations with a strict attention to keeping the arms generally straight.

3. Examine your protein supplements closely.

With the recent popularity in protein supplementation, it’s no shock that everyone is trying to make a quick buck off those looking to pack in more protein. It wasn’t too long ago that you had to seek out an actual nutrition store to purchase products like “ready to drink” protein shakes. Nowadays you can find these at pretty much any convenience store, or gas station mini mart. Furthermore, there was also a time that you could count the manufacturers of protein supplements on one hand, or two at the most. Most of them tasted like cardboard, and you needed an industrial blender to try and make that stuff into something resembling liquid. This has obviously changed - some for the better, and some for the worse. Before picking up your next tub of powdered goodness, take a look at the ingredients. In a similar fashion to what we discussed a few weeks back with food labels: the flashy front promises are often hiding a less than impressive host of ingredients on the back.

First, look at what type of protein you’re getting. Whey is not whey, is not whey, is not whey. Cheaper products are predominantly whey concentrate which is of lesser quality than whey isolate, or the more rapidly usable hydrosylate. It also tends to be harder to mix. Furthermore, if it isn't whey, what's the protein source? Is it soy, milk, egg, hemp, pea, or unicorn blood? Next, how are they making this stuff taste so darn good? Check for added sugar, and the use of artificial sweeteners. Lastly, be weary of the ready-to-drink variations; they are most likely full of chemicals, preservatives, and other things my high school chemistry curriculum failed to cover.

There are definitely reliable sources of protein supplements out there, though. I like to mix up the companies I use, and also the sources. I realize you could get pretty scientific about what works best and when, but I have other things to do. Mixing the source, and attaining them from quality places have served me well; I advise you do the same!

4. Layer up to beat the cold.

Fall is here in New England, and that means the cold weather is almost upon us. I have something to confess: I sweat on an absurd level. Needless to say, fall is a nice change of pace for me. I can wear a color other than black on a date, and I don’t have to buy nearly as much deodorant.

While my perspiration woes are a menace to my social life, I like being sweaty in the gym. As it gets cooler, I wear sweats and spandex or compression pants, shirts and sleeves. Plus, it seems like the perfect time to have an excuse to wear a beanie while training and not look like I am trying to just be a total badass. Do note, however, that I am perfectly okay with wearing anything that makes you feel badass, anytime.

As an aside, though, Cressey Performance does sell beanies; you can buy one online HERE.

It’s more than just a personal preference, though; it will help improve your training quality. Warm joints and muscles are happy joints and muscles. To take it a step further, warm people are happier people too - and that makes them far more motivated to train. Keep this in mind when leaving the house to train. Take a hot shower, layer up, warm up the car, and take any other preventative measures needed to prevent you from entering cold weather hibernation. Your training quality will stay up, and your consistency will continue.

5. Think twice about implementing icing for post-training recovery.

Icing has become a common prescription to help aid recovery of sore muscles. The research has always been less than stellar as to the actual merits of its application, though. Still, ice baths, bags of ice, and cooling packs have been a staple in gyms and training rooms across the country. And, if people are doing it, and claiming it helps them, then why not do it? There are, of course, different ways to use ice. Are we treating inflammation, or muscular soreness?

A recent study published in The Journal of Strength and Conditioning Research found that icing actually reduced recovery from eccentric exercise induced muscular damage. Participants were given cooling packs for the associated muscles affected by a controlled exercise. The pack was applied at various times for 15m in duration, post-training. The group who was given the cooling treatment did not improve recovery; in fact, it delayed the recovery process in comparison to the group who was not. Given this information, people should place a premium on other modalities to improve recovery. These include soft tissue work, compression, and low level activity in the 24-48 hour period following eccentric exercise.

There still may be some merits to icing in certain situations, so be careful to discard this modality altogether.  However, it's clear that more research is needed to determine if/when it should be used.  For additional reading along these lines, I'd encourage you to check out Kelly Starret's recent blog post, People, We've Got to Stop Icing.
