  Your body has build-in regulators to prevent massive increases in muscle growth.

 When we overeat our body turns on counter-regulatory factors to prevent the build-up of muscle mass.

  Some Examples:

  Overeating causes decreased testosterone levels in men

  Overeating causes decreased insulin sensitivity in men and women.

  Overeating also causes increased low grade systemic inflammation

 While some inflammation is good for you, low grade systemic inflammation blocks muscle growth and is associated with a host of chronic diseases.

  Latin: inflammare, to set on fire

  There are two main types of inflammation.

Acute and Chronic

  Acute Inflammation is a biological response to harmful stimuli

  It is how your body removes the injurious stimuli and initiates the healing process

 Without acute inflammation, wounds and infections would never heal

  However, long term chronic inflammation is associated with many different disease states, including obesity, and the loss of muscle mass.

  Especially when the chronic inflammation is systemic – throughout your whole body.

  Other than the obvious health reasons (prevention of disease), you should also care about inflammation because it plays an important role in regulating muscle growth.

  Based on the ‘Signal and Noise’ theory of inflammation’s role in regulating muscle growth, inflammation can both cause and prevent muscle growth.

  It is also how many different lifestyle factors (like chronic endurance training) can actually prevent optimal muscle growth.

  The role of inflammation in the muscle growth depends on whether or not the inflammation is systemic or localized.

  Simply put - the Inflammation Theory of Muscle growth is as follows:

The Inflammation Theory of Muscle growth:

Above: The Acute Inflammation Response to periods of Resistance Training in a person with no chronic Inflammation. Each spike represents the inflammation caused by a workout. The spikes are large enough to initiate the signal for new muscle growth.

Below: The Same Acute Inflammation Response to periods of Resistance Training in a person WITH chronic inflammation. The Spikes are hidden by the ‘noise’ and thus muscle growth is not initiated.

  Chronic inflammation is the body’s response to a chronic harmful stimuli, such as excess body fat or other chronic metabolic ‘insults’.

  Low grade chronic inflammation is characterized by a 2 to 3 fold increase in the systemic concentrations of cytokines such as TNF-alpha, IL-6 and C-reactive Protein.

  This type of inflammation is systemic, meaning it is not localized to any one part of your body.

  In the case of Obesity the extra fat is the ‘harmful stimuli’ that is causing the inflammation; however our bodies cannot get rid of the fat with the inflammation response and thus will stay inflamed as long as the extra fat is still present.

 Not only can obesity cause chronic inflammation, but the very act of overeating can also lead to systemic (whole body) inflammation.

  A single large meal is enough to start to raise many markers of inflammation.

  This inflammatory response is larger in an overweight person then it is in a lean person.

  Having excess body fat can cause chronic inflammation AND increases the inflammatory response to a large meal.

  In other words an overweight person will have a higher systemic inflammation response to a high calorie meal then a lean person.

  Cytokines are small cell-signaling protein molecules

  Typically cytokines are immunomodulating agents, such as interleukins and interferons.

  Basically, a cytokine is either inflammatory or anti-inflammatory.

  3 Common types of inflammatory cytokines: TNF-Alpha, IL-6 and CRP

  TNF-Alpha is proposed as the main driver of chronic low grade inflammation

  IL-6 increases several fold post-exercise after exhaustive exercise

  C-Reactive Protein - acute-phase protein, elevated in inflammation and illnesses such as cancer

 Muscle growth isn’t the only reason to keep low grade inflammation at bay.

  Low grade systemic inflammation is also associated with many diseases, including:

 Acne,

 Rheumatoid arthritis,

 Hypertension,

 atherosclerosis,

 Fatty liver,

 Asthma,

  Insulin resistance and diabetes,

 Cardiovascular disease,

 Alzheimer Disease,

 And even the aging process itself.

  Chronic Inflammation is a process that seems to be an underlying mechanism in many forms of cancer

  It is also a possible link between obesity and cancer.

  Surprisingly, this inflammation-cancer link was suggested as far back as the late 1800’s when German Pathologist Rudolf Virchow stated:

“Chronic irritation which is manifested by a chronic

inflammation is a key promoter of cancer.”

  Chronic inflammation is widely observed in obesity.

  People who are obese commonly have many elevated markers of systemic low-grade inflammation, including:

  IL-6,

  TNF-Alpha,

  CRP,

  Insulin,

  Blood glucose,

  Leptin

  IL-18

  This relationship also seems to be dose-dependent, meaning the more obese a person is the more inflammation they tend to produce.

  One of the most important predictors of low-grade inflammation is your Waist circumference.

 Waist circumferences over 50% of height are associated with low-grade inflammation and this relationship increases as waist circumference increases.

  Adipose tissue has been shown to produce 10-35% of IL-6 in a resting individual, and this production increases with increasing adiposity.

  Thus there is a link between increasing levels of obesity, and increasing levels of inflammation.

 Within reason, the lower the body fat, the lower the overall levels of systemic inflammation.

  To make matters even worse, obesity increases inflammation, which in turn promotes fat cells to secrete even more inflammatory cytokines.

  Inactivity and chronic overeating only makes this problem worse.

  Inflammation leads to lowered testosterone, insulin resistance, and possibly leptin resistance.

  Excess fat leads to inflammation, which leads to more fat, and more fat leads to more inflammation.

  This sets up the perfect downward spiral into disease (And definitely a complete lack of muscle growth potential).

  Having high levels of blood sugar is called Hyperglycemia – and it occurs after a large sugar containing meal.

  Hyperglycemia induces the release of the inflammatory cytokine IL-6 into your blood stream.

  Thus high carbohydrate meals are associated with an increase in inflammation.

 Meals containing high levels of saturated fat have also been associated with increased markers of inflammation.

  High calorie meals containing carbohydrates, fats and proteins have been associated with increasing inflammation.

  This response is elevated in people who are obese.

  The acute inflammation response is the bodies response to insult and injury

(Think Bee sting)

  It Involves the mobilization of Cytokines and other immune molecules to protect the body.

  Role of acute inflammation is to remove the injurious stimuli and damaged tissue and to initiate the healing process

  It is localized (happens in one spot), as opposed to systemic low grade inflammation which happens all throughout your body.

 Muscular contractions from a weight training workout are what sensitizes a muscle and allow it to increase in size.

  After a person has grown to their full adult size, this is the only way to induce muscle growth, outside of using anabolic drugs.

  This has been shown in research using:

  Cross Sectional Area

  Fractional Synthetic Rate

  Amino Acid Markers

  Increases in Muscular Strength

  Increases in Muscular Weight

  The right amount of work at the right effort can sensitize a muscle to the the anabolic signal that comes from eating a meal containing protein.

  In other words it is weight training that makes eating protein effective at building muscle.

 Workouts alone do not build muscle. They sensitize the muscle by initiating the anabolic process.

  Eating protein alone will not build muscle. The muscle must be sensitized for eating protein to contribute to the muscle growth process.’

 Working out sensitizes a muscle, allowing it to grow when given a high amount of amino acids.

  This sensitization lasts for over 24 hours.

  However, it is the ‘signal’ that sensitizes the muscle that we are interested in.

  There is a known relationship between inflammation and muscle growth.

  Acute localized inflammation is a response to muscular contractions and is necessary for muscle growth. It ‘starts’ the repair process.

 Muscles can synthesize cytokines in response to contractions. So the inflammation that comes from a workout is localized – it happens inside the muscle that was exercised.

  High doses of anti-inflammatory medicines are able to blunt muscle growth by blocking this inflammation response, so we know that it is a necessary component of muscle growth.

  The inflammation response caused by a workout plays a role in the degeneration and regeneration process of muscle and surrounding connective tissue.

  As a response to muscular contractions the acute inflammatory response initiates the breakdown and removal of damaged muscle tissue – the ‘good’ type of protein catabolism.

  Elevations in localized inflammation can last up to 5 days after a workout, adding evidence to the fact that muscles continue to be sensitive to the anabolic affects of eating protein for an extended period after a workout.

  The cytokine IL-6 is an important marker of acute inflammation.

  It is released by muscle cells as a response to muscular contraction.

  This increase can be up to 100 times above resting levels.

  The amount of IL-6 released depends on total workload during the workout and intensities of the workout.

  The IL-6 increase caused by a workout starts to increases about 4 hours after the workout and remains elevated well passed 24 hours after the workout.

  How long IL-6 remains elevated also depends on the volume of work and the amount of effort or strain caused by the workout.

*The inflammation response from a workout causes increased glucose uptake, fat oxidation and satellite cell activation.

  Satellite cells are like ‘dormant muscle seeds’ that sit on the outside of the muscle fiber (hence the name satellite cells).

  They are present in all skeletal muscles and are associated with all muscle fiber types - albeit with unequal distribution (some muscles have more some have less)

  You can think of satellite cells as the body’s reserve of muscle cell nuclei.

  Satellite cells are crucial for skeletal muscle adaption to exercise.

 Without satellite cell activation there would be very little possibility for muscle growth in the human body.

  Satellite cells contribute to hypertrophy by providing the new myonuclei needed to repair damaged segments of mature muscle fibers for successful regeneration following injury or exercise induced muscle damage.

  High level power-lifters can have up to 100% more satellite cells than untrained controls.

  Supplemental testosterone also increases satellite cell number.

  Without satellite cell activation muscle growth cannot occur.

  Once a satellite cell has been incorporated into a muscle fiber it stays there for years, even without exercise, allowing the muscle to keep a memory of its previous size (this is often referred to as ‘muscle memory’)

  Scientists have tested the importance of satellite cells by using low dose radiation in animal studies to destroy the satellite cells in one leg.

 When this happens the muscles exposed to radiation can still adapt to exercise by becoming more efficient, but with the exception of a small amount of beginner growth, they simply cannot increase their size.

  In other words, because they could not add more nuclei, they could not increase their size in response to resistance training.

  Adding more exercise, or high doses of amino acids cannot induce muscle growth without the help of satellite cells acting as the ‘brain’ that puts it all together.

  Satellite cells have receptors that detect localized acute inflammation, (IL-6 receptors) and these receptors increase following a workout.

  The inflammation marker IL-6 has been shown to mediate muscle growth.

  Unaccustomed exercise can increase IL-6 by up to 6 fold at 5 hours post exercise and 3 fold 8 days after exercise.

 When Exercise induced inflammation is blocked by taking high doses of anti-inflammatory drugs satellite cells cannot response to exercise stimulus and post-exercise protein synthesis is decreased.

  Both resistance training (weight lifting) and endurance training (long distance running) increase inflammation.

  However, the response is uniquely different.

  The cytokine response to endurance training such as running is slightly lower and more pronged, not reaching its full peak until the 12-24 hour mark.

 While both types of exercise stimulate inflammation, the different ways in which inflammation is stimulated changes how each one is able to stimulate muscle growth.

  Some form of resistance training must be completed on a consistent basis for muscle growth to occur.

  Even a small increase in chronic inflammation can increase the risk of muscle strength loss and cause a decrease in your ability to build muscle.

  Chronic inflammation has been implicated as part of the cause of the muscle loss that occurs with aging (sarcopenia).

  Increased protein levels of myostatin have been described in patients with diseases characterized by chronic low-grade inflammation, limiting their ability to build muscle.

  Increased levels ofinflammation can suppress the AKT/mTOR pathway - an important pathway in the muscle building process.

  Inflammation may decrease the anabolic effects of IGF-1.

  Sepsis is an extreme whole body inflammatory state that is able to inhibit the synthesis of both myofibrillar and sarcoplasmic proteins preferentially in muscles composed of fast twitch fibers.

  (Sepsis prevents the creation of new muscle proteins)

  Sepsis is able to prevent leucine from stimulating muscle protein synthesis.

  In animal models when inflammation is created mTOR loses it’s ability to be stimulated by muscle growth

Blocked by Chronic Inflammation

 Research has identified 6 major sources of inflammation that are considered ‘lifestyle factors’ since they do not come from a disease:

 Chronic Exhaustive Exercise

 Stress

 Aging

 Lack of Sleep

 Overeating

 Obesity

 FIVE of these sources must be addressed for optimal muscle growth (Sadly, we can’t control aging)

Body fat:

 Excess body fat is one of the strongest predictors of overall chronic inflammation, and the inflammation response to high calorie meals.

  In order to keep low-grad inflammation at bay, keep your waist circumference below 50% of your height – especially when attempting to bulk.

 Occasional periods of low calorie intake will serve to keep inflammation low, and keep your waist within acceptable limits.

TO OPTIMIZE MUSCLE GROWTH:

Keep your waist circumference UNDER 50% of your height at all times if you are trying to build muscle.

 Weight Loss achieved through different diet programs with or without exercise resulted in decreases of markers of low grade inflammation by 7 to 48%.

  Calorie restriction is anti-inflammatory, this includes brief periods of fasting.

 Weight loss is effective at reducing inflammatory markers, specifically IL-6 and Leptin

  Losing weight and maintaining a ‘healthy’ weight is your best solution for minimizing inflammation levels.

 Maintain a ‘healthy’ weight is also your best solution for building muscle mass.

TO OPTIMIZE MUSCLE GROWTH:

Do not gain fat in an attempt to ‘force’ muscle growth. It does not work and you will regret it.

OVEREATING:

  Extremely large meals cause an inflammation response, and this response is heightened in people who are already obese.

  For the purpose of muscle gains, keep cheat days or cheat meals to a minimum until your waist circumference is under 50% of your height.

  Even then, use this dieting technique sparingly if you are trying to gain muscle mass.

TO OPTIMIZE MUSCLE GROWTH:

No cheat days until your waist circumference is under 50% of your height.

LACK OF SLEEP:

  Do not underestimate the power of sleep in the recovery process.

  Sleep is far more important then massive amounts of calories or even overeating protein for recovery after a workout.

  Lack of sleep (not enough in a night) or disrupted sleep (multiple periods of wakefulness during the night) area associated with:   Increased inflammation

  Decreased insulin sensitivity   Overeating   Weight gain

TO OPTIMIZE MUSCLE GROWTH:

If you are having trouble sleeping consider taking the supplement ZMA before bed.

STRESS:

  The effect of stress on chronic inflammation is VERY real.

  Plasma levels of inflammation markers are higher in workers suffering from ‘burnout’ then in those not suffering ‘burnout’

  Elevated markers of inflammation are associated with excessive daytime sleepiness, disturbed night time sleep and daily lethargy.

  It is speculated that many of the people who claim to be suffering ‘adrenal fatigue’ are actually suffering from chronic-low grade inflammation.

TO OPTIMIZE MUSCLE GROWTH:

Inflammation, adrenal fatigue, and overtraining are all similar terms to describe and overall feeling of chronic exhaustion

Chronic Exhaustive Exercise

  There more than100 original scientific reports concerning exercise and inflammation Showing a strong relationship between exhaustive exercise and chronic low grade inflammation

  Marathon running may enhance IL-6 levels as much as 100 times over normal and increases total leuckocyte count and neutrophil mobilization.

  Low grade inflammation caused by chronic exhaustive exercise can blunt your ability to gain muscle by blunting the inflammation response and your anabolic response to eating protein.

TO OPTIMIZE MUSCLE GROWTH:

If you are trying to gain muscle, then you should avoid exhaustive exercise, especially if you are currently overweight (waist circumference above 50% of your height)

NUTRITION:

  Other than eating less, the are very little types of dietary changes that need to be made in order to lower grade systemic Inflammation.

  Adjusting your protein, fat or carbohydrate intake causes very little change in markers of inflammation.

 When it comes to reducing inflammation it truly is how much you eat more than it is what you eat.

  Herbs and spices may have anti-inflammatory effects or at least lessen some of the negative effects of inflammation, so if you were going to make one change on top of eating less, I would recommend eating more herbs and spices on a day-to-day basis.

SUPPLEMENTS:

  You must be careful with your use of supplements as some may actually decrease the acute inflammation response to exercise (possibly lowering muscle building potential).

  Don’t drink carbohydrates during your workouts - Post or during workout Carbohydrate supplementation has been shown to be able to decrease the IL-6 Response to high intensity running.

  Avoid taking high dose vitamin C - Daily high dose Vitamin C supplementation may also blunt the contraction induced acute inflammation.

  Whey protein is a ‘safe’ supplement - Neither acute nor long-term whey protein supplementation have any effect on the major markers of inflammation.

  Avoid CLA while attempting to build muscle. -Conjugated Linoleic Acid (CLA) seems to be able to increase markers of inflammation

  Fish Oils are good, but do little to reduce inflammation - Studies of dose-response between fish oils and inflammation have found that even high dose (3.4 g/d of EPA and DHA) did not change inflammatory status over 8 weeks.

  Irvingia gabonesis has a lot of potential - it seems to have the ability to decrease low-grade inflammation

  Regular physical activity is reported to decrease markers of inflammation.

  Baseline measurements of circulating inflammatory markers do not seem to differ greatly between healthy trained and untrained adults

  However long-term chronic training may help reduce chronic low grade inflammation

  Levels of inflammatory markers (IL-6) remained elevated longer into the recovery period following and acute bout of exercise in patients with inflammatory diseases as opposed to healthy controls.

  Research has shown that there is a strong trend towards reduced post absorptive muscle protein synthesis associated with aging.

  This means as we get older we get less of a muscle growth response from eating protein.

  Evidence suggests that this is related to increased circulating levels of inflammatory cytokines TNF-Alpha, IL-6 and CRP

 High levels of circulating IL-6 can predict muscle atrophy in the elderly

  The increased inflammation associated with aging blunts our ability to gain muscle.

  The affect of exercise on inflammation seems to scale the level of exhaustion associated with the exercise.

  Low intensity training such as walking can reduce resting pro-inflammatory markers.

 Moderate exercise can have some anti-inflammatory benefits, protecting against the development of low grade inflammation.

  Strenuous or exhaustive exercise can increase inflammation.

  There is a strong relationship between Testosterone and inflammation in men.

  Low levels of testosterone are associated with increased levels of inflammation.

  Testosterone injections result in profound declines in markers of inflammation

  Testosterone is able to suppress the expression of many different inflammatory cytokines (IL-6, IL-1B and TNF-Alpha)

  Testosterone can also stimulate the production of anti-inflammatory IL-10

  Testosterone is able to decrease inflammation and increase anti-inflammatory markers.

  Overeating has been purported to add in the muscle building process in young, non-steroid using athletes.

  This does work for a short period, however this effect seems to decrease with time, leading to speculation that the slow build up of inflammation eventually reaches a point where muscle growth is blunted.

  This time course would depend on the degree of overeating and speed of fat gain in the individual.

  The faster the fat gain, the quicker the muscle gains stop.

  However, the use of testosterone could allow for a prolonged anabolic signal from overeating, as it would prevent both the decrease in testosterone usually associated with overeating, as well as the increase in inflammation induced by overeating.

  Bottom line: Don’t take bulking advice from people using steroids.

  Gaining fat and grossly overeating is NOT the answer!

  Controlling Inflammation is the answer.

  Low grade chronic inflammation brought about by any combination of overeating, obesity, stress, lack of sleep, aging, and exhaustive exercise will blunt muscle growth signals form both exercise and diet

  Decreasing chronic inflammation may allow for a return to proper anabolic signaling.

  However, it seems wiping out inflammation completely also prevents the acute local inflammation needed for muscle growth (as evidenced by high does NSAID Studies)

  Utilizing the signal/noise theory of the role of inflammation in muscle growth it seems very plausible that the best course of action for long term muscle growth is the opposite of what we have been lead to believe.

  Keep body fat low, get lots of sleep, and avoid excessive use of exhaustive exercise for optimal muscle growth and long term health.

  If your waist circumference is above 50% start with a goal of decreasing your body fat before you start to attempt to ‘eat up’ to build muscle.

  Once your waist is below 50% of your height, eat as much as you can WITHOUT gaining fat (Eat but do NOT over eat).

  Any time your waist reaches 50% of your height, lower calories again, in order to keep from building up chronic low grade inflammation levels.

  Train consistently, and match strenuous exercise with periods of light exercise (active recovery).

  Consume 1-4 protein meals in-between each workout to take optimal advantage of the sensitization that occurs when you workout while in a low-inflammation state.

  The occasional brief fast may help keep inflammation low, while still allowing for a calorie intake the allows for muscle growth on the days you are not fasting. For this reason fasting once or twice a week during a muscle building phase is ideal

  Use anti-inflammatory drugs sparingly after a workout. Use them when they are needed, but keep in mind they may blunt the inflammation response to exercise.

  Carbohydrate drinks during a workout may also blunt the exercise induced inflammation response.

  Creatine monohydrate may increase the amount or sensitivity of your satellite cells.

  Keep your waist circumference below 50% of your height at all times.

  Avoid periods of excessive overeating.
