Protein – What’s the Role?

When patients, clients, and friends ask me about protein, there seems to be a lot of confusing information as to the purpose of increasing one’s intake of protein for muscle building, fat burning, and the use of protein throughout one’s exercise patterns.

So let’s say that you want to build some lean mass.  Muscles growth occurs when a stimulus or range of stimuli placed upon the muscles, tendons, ligaments, and bones is significant enough that it causes the muscles to adapt and change by increasing the size of muscle fibers as well as the amount of muscle fibers a motor unit can innervate/activate to increase an individual’s strength.  In other words, lifting heavy weights and performing resistance exercises is how you grow and strengthen your muscles.  Consuming protein alone will not get it done.

An important principle behind hypertrophy (increased your muscle size) is the concept of progressive overload meaning that with increased sets, weight, and repetitions, this effect will cause growth in muscles.

If you choose to swap out carbs for a diet high in protein, you will also increase your chance of success with weight loss according to the American Journal of Clinical Nutrition.  Why you ask?  Your body spends more energy processing dietary protein than carbs.  For everyone 100 calories of protein that you consume, 20-30% of those calories are burn by your body as opposed to 5-10% of those calories being burned by the body for 100 calories of carbs.

These are some of the reasons why the feeling of satiety becomes more effective with protein than carbs or fats.  Because it takes our body’s longer to burn protein than carbs or fat, our body tends to absorb more of the nutrients in a high protein diet.  This allows the body to preserve its lean mass which allows individuals to have faster metabolism to aid in body fat loss when at rest.

How much protein do I need?            

For those that are wondering how much protein you should incorporate into your diet is dependent on the specific goal that you are reaching for.  According the American College of Sports Medicine, the recommended daily protein intake for athletes is 1.2 – 1.8 grams per kilogram of body weight to achieve increase muscle mass along with resistance training.  Individuals that are less active will require less protein (0.8-1.0 grams)
