Facing Fears – Starve a Fear; Nourish a Soul

Written by FitRx on . Posted in Blog, Etc

For you Fit Rx alumni, here is a refresher; for you newbies I hope this helps. We are all facing fear in various forms, and in case you’ve forgotten, here are some tips on how to move forward in spite of them. Let’s all agree that we have been slaves of fear far too long!

Fear is a distressing emotion aroused by impending danger, evil, pain, etc., whether the threat is real or imagined; it’s the feeling or condition of being afraid. Synonyms: foreboding, apprehension, consternation, dismay, dread, terror, fright, panic, horror, trepidation.

“Too many of us are not living our dreams because we are living our fears.”

-Les Brown

Strategies to Face and Move through Fear

  1. Find out what the fear behind the fear is! For example, the root of most performance fears, the fear behind the fear, is often “I’m not good enough” or “They won’t like me.”  Identifying the true fear creates awareness, the first step in creating change.
  1. Ask “what is really true?” F.E.A.R. = “False Expectations Appearing Real.” It’s a great reminder that our minds think the threat is real.  If I ask myself what is really true, then, as with public speaking, I can admit that I am good enough, know enough – maybe more than my audience.  The truth is I am capable of speaking in front of anyone when I’m in my most confident state.
  1. Play the “what if” game. What is the worst that could happen?”  To play the game, ask yourself “What if my fear happens, then what? And what if THAT happens, then what?”  By the time you follow this path a few times, the possible outcomes start to seem preposterous and the real risk is put into a new, less threatening perspective.  You also start to calmly prepare for reasonable unexpected events.

(Note - be mindful that “worst case scenario” thinking usually cripples us and doesn’t benefit us. Despair expects horrible things around the corner. Hope expects good things around the corner.)

  “Fear makes the wolf bigger than he is.”

-German Proverb

  1. Make sure you are spiritually and emotionally grounded. I use deep breathing, prayer, inspiring quotes, YouTube videos, movie scenes, and positive present-tense affirmations to get myself centered and calm.  I return to my confident state of mind by reviewing my successes and my belief in myself no matter WHAT happens.
  1. Ask for help. Turn to someone you trust, with whom you feel safe, who you know cares about you and ask them to go with you, help you, hold you accountable to facing your fear. Verbalize your fear and commit to facing it. When we verbalize our fears it can help to disempower them.

More Troubles with Sitting – and What Won’t Help

Written by Dr. Ralph E. Carson on . Posted in Blog, Exercise, From the Desk of Dr. Carson

In his first of two articles, Dr. Carson presented evidence showing that sitting for long, uninterrupted periods has serious health risks. And he followed that with some techniques for mitigating or avoiding those risks. Here is a brief addendum to underscore both the risks and the ways to counteract too much sitting.

 Troubles with Sitting – Orthopedic Health Problems attributed to too much sitting

(Mathews ’12; Ford ’12; Berkowitz; Hamilton ’07; George ‘13)

Muscle degeneration (Back problems)too-much-sitting-back-pain

  • Slumped muscles go unused — tight back and weak abdominal muscles combined to cause serious back pain due to extreme lower curvature (lordosis)
  • Sore back: inflexible spine movement causes soft disc dehydrated and brittle. This can lead to a herniated disc. Typically the disc between vertebrae expand and contract like a sponge soaking up fresh blood and nutrients with activity.
  • Collagen hardens around supporting tendons and ligaments with extended inactivity

Tight hips: decreased hip mobility due to tight hip flexors (short and tight) limit range of motion and produce falls

Limp gluts (buttocks): hurt stability and stride

Strained neck: Craning neck forward over key board or tilting head to cradle phone

Sore Shoulders

Soft bones: Weight bearing exercises cause bone to grow thicker and lack thereof causes osteoporosis


Sitting can reduce life expectancy

Standing could increase your life span. The more time on your feet strengthens the bits of DNA called telomeres (Sjogren ’14). Telomeres protect the ends of chromosomes (like the tips that keep shoelaces from fraying). Telomeres tend to get shorter and shorter until they can shorten anymore and cause cell death.

Women who spend too much time sitting around (>11 hours/d) had a 12% risk of premature death (13% more cardiovascular disease; 21% more cancer; 27% more coronary artery disease) than those who were inactive for <4 hours (Sequin ’14).


Can scheduled exercise sessions offset the negative effects of sitting?

Adults spend 50% – 70% of their waking hours sitting or approximately 8 hours per day. Sitting for extended periods of time can harm even those that exercise (Craft ’12; Wilmot ’12). The increased risk of sitting is not offset by moderate to vigorous exercise or meeting the recommended physical guidelines. Regular exercise does not reduce the risk of an otherwise sedentary life style as one remains susceptible to just as great a risk of diabetes, cardiovascular disease, obesity and premature death. Short but frequent walks or alternative activity sparks (short term episodes of movement lasting 5 – 10 minutes) can counteract the harm caused by sitting long periods.

15 Tricks to Avoid Sitting Risks

Written by Dr. Ralph E. Carson on . Posted in Blog, Exercise, From the Desk of Dr. Carson

Don’t just sit theretry these

(Ekblom-Bak ’12; Loprinzi ’13; Yancy ’10; Healy ’08)

Last week, we learned of many possible health risks caused by habitual, uninterrupted sitting over long periods. Since it’s not how much but how often you exercise that matters, you can counteract the harmful effects of sitting with small lifestyle adjustments. The following activities may do just as much good as formal exercise to reduce chronic disease such as heart attacks, stroke, cancer, and diabetes (Ekblom-Bak ‘13).

An active lifestyle is an effective way to provide health benefits such as preventing high blood pressure, high cholesterol, and metabolic syndrome. Despite not exercising according to the recommendations, as many as 40% of adults may be achieving the exercise guidelines by making movement part of their life (Loprinzi ’13).

If your lifestyle requires a lot of sitting, try breaking up the stasis with some of these healthy movement activities:

  1. Standing with computer on top of the filing cabinet
  2. Sitting on exercise (stability) ball instead of desk chair
  3. Dance about, wiggle around, take a few steps back and forth, fidget
  4. Standing during meetings
  5. Standing talking on the telephone
  6. Walking during lunch breaks
  7. Gardening and lawn care
  8. Housework (vacuuming and mopping floors)
  9. Stand folding laundry or ironing
  10. Do-it-yourself projects
  11. Marching in place during TV commercials
  12. Getting up from your desk and doing jumping jacks, knee lifts and bends
  13. Purchase an activity monitor
  14. Set a timer for to go off once per hour
  15. Move printer farther away
  16. Sit up straight
  17. Take water breaks

Love at Three G’s

Written by Marianne Messina on . Posted in Blog, Etc

Three Tips to the Lovelorn from FitRx Therapist Jonathan Rios

“Envy is the art of counting the other fellow’s blessings instead of your own.” – Harold Coffin

For many, the month around Valentine’s Day is a reminder of lost loves, longing for love, or even love not yet experienced. We can all agree, ours is a culture obsessed with fairy tale lovers and happily ever afters.

When these expectations aren’t met, our hearts are easily wounded. Those of us who don’t have a current love often turn to thoughts of our “lack” and become intensely critical of love itself. In fact, we may even find ourselves bitter towards those around us who seem to have found that “true love.” Does this sound like you?

Photo Credit:

How about any of these:

  • Are you unable to be happy for the love others have found?
  • Is it hard to congratulate others on their relationships?
  • Do you secretly rejoice when others experience heartbreak?

If you found yourself answering even the tiniest “yes,” let these three g’s help you avoid the trap of becoming embittered:

Gratitude – Write down all the romantic and platonic relationships (past and current) that have been a blessing in your life. (What lessons did you learn about yourself?). Instead of meditating on all the “misfires” and “heartache,” flip your focus to that of thanksgiving.

Generosity – Realize there’s someone in your immediate community who is “heartbroken” this year and could use a dose of love themselves. (Get the focus off of you and onto others.) Bring them a gift. Offer to babysit. Write them a note. Take them out for dinner. Actually verbalize how important they are to you.

Grace – Give yourself an unmerited treat. See a movie that inspires you. Spend time with people who care about you. Watch YouTube clips of your favorite comedian.  Visit your favorite museum. Go hiking. Go on a road trip. Call out sick. Declare a “self-enrichment day.”

It’s virtually impossible to be both jealous and grateful at the same time. Our internal world is one of constant tensions and we must do the hard work of choosing which thoughts and emotions will steer the ship.

This month of Valentine’s, I implore you to choose love in the truest sense by loving yourself and giving yourself away to the people around you. Someone nearby needs what you have to offer.


The Trouble with Sitting

Written by Dr. Ralph E. Carson on . Posted in Blog, Exercise, From the Desk of Dr. Carson

Are you doing too much sitting?
Metabolic Health problems attributed to “too much sitting”

 The last few years have seen a good bit of research showing health risks associated with “too much sitting,” where “too much” suggests periods of more than an hour at a time. For better or worse, here’s a list of the bodily systems found to be compromised by “too much sitting.”

Heart Disease:

  • Blood pools in legs because muscles are not contracting and pumping blood effectively
    • Impairment of endothelia function (inability of arteries to expand). Endothelia function is reduced by over 50% with just one hour of sitting (Thosar ’14).
    • Men who walked 5 minutes per hour had no reduction in function of arteries during a 3-hour period
  • Blood flows more sluggishly during a long period of sitting allowing fatty acids to more easily clog the heart
  • Linked to high blood pressure
  • Linked to high cholesterol
  • Twice as likely to have cardiovascular disease
  • Older men who spend a great deal of time sitting are more than twice as likely to face heart failure even for those who exercise regularly (Young ’14)
  • Men reporting 24 hours per week of sedentary activity have a 64% greater risk of dying from heart disease than those who were inactive < 11 hours per week (Blair ’11)

Metabolic Syndrome (Bey ’03)

  • Decrease in lipoprotein lipase (LPL) in skeletal muscle explains poor lipid metabolism and metabolic syndrome
  • Riding in cars and watching TV are significant predictors of metabolic syndrome (High BP, high triglycerides, High cholesterol, high blood sugar and excess belly fat) (Warren ’10)

Diabetes (Over productive pancreas)



  • Most consistent association of sitting and diabetes (Wilmot ’12)
  • Three (15 minute) bouts of moderate post meal (30 minutes after meal) walking significantly improved 24 hour blood sugar control in older people at risk of impaired glucose tolerance (DiPietro ’13)
  • Interrupting sitting time by walking lowers post prandial (after meal) glucose and insulin levels in overweight and obese (Dunstan ’12)
  • Cells in sedentary muscles do not respond readily to insulin – pancreas as a result has to produce more insulin
  • Decreases in insulin response were seen just one day of prolonged sitting (Stephens ’11)

Cancer (Schmid ‘14b; Zhang ’14)

  • Colon cancer (Schmid ‘14a)
  • Breast cancer
  • Endometrial cancer
  • Excess insulin encourages cell growth
  • Movement boosts natural anti-oxidants that scavenge and destroy cell damaging free radicals

Poor circulation in legs

  • Fluid pools, swollen ankles, varicose veins, and deep vein thrombosis (DVT)

Larger waistline

  • Burn 6x fewer calories
  • Risk of inflammation (due to visceral abdominal fat) which can result in heart disease, diabetes and metabolic syndrome
  • Each hour of daily sitting was associated with 2.39 cm of pericardial fat (fat collecting around the heart) and explains the high incidence of coronary heart disease. This pericardial fat stayed in place even when undertaking exercise (Larsen ’14)

Foggy brain

  • Circulation triggers release of cognitive and mood enhancing chemicals

FDA-approved “Gastric Pacemaker” – What do the studies say?

Written by Dr. Ralph E. Carson on . Posted in Blog, From the Desk of Dr. Carson

For many years, gastric electrical stimulation (GES) has been under investigation as a treatment for obesity and overeating, but until last week, it has only been experimental. After 12 years, the FDA finally approved EnteroMedics device for treatment of obesity, making it the first “gastric pacemaker” to be approved for obesity treatment.

About the size of a pacemaker and implanted into the person’s abdomen, the EnteroMedics’ Maestro™ device is intended to offer potential weight loss for those struggling with obesity. Called VBLOC™ for vagal blocking therapy, its electrode touches the vagus nerve at a point between the esophagus and the stomach, and it works by intermittently down-regulating or blocking input from the stomach’s vagal nerve to part of the brain linked to appetite in people who have issues with obesity and metabolism.

Historically, the independent research of such devices has not been earth shattering. Both SBU (’04) and Buchwald (’02) felt that the results were not conclusive and that EGS did not provide satisfactory results. This discouraged them from carrying on with the study (Salvi ’09).

In a 2009 study, Shikora et al compared implantable gastric stimulation therapy to a standard diet and therapy regimen. Within their group of obese subjects, the team evaluated differences in weight loss and found that the control group lost 11.7% and the IGS group also lost 17.6% of excess body weight. The difference in results between the two groups was less than a high recommendation of the treatment.

In a more recent study, after 12 months with the EnteroMedics device, those with the device fitted lost an average of 24 per cent of their excess weight, while those in the control group without the device fitted lost only 16 per cent. The device produced an overall difference in total body weight of only 3% over the sham device, which did nothing (Ikamuddin’14). Therefore, though there was certainly clinically significant weight loss with this device, the procedure fell short of being as effective as the researchers had hoped.

Repeated evidenced-based failures to support the “stomach fullness theory” suggest seeking alternative signals to relay cessation of eating. This adds credibility to the idea that the primary feedback may be dictated by satisfaction rather than fullness. This suggests placing more emphasis on hedonic (pleasure) messages in research and potential therapy.

While this FDA approval may show some promise, who will it work for, what will it work with?

There are still several important under-researched questions to consider coming out of the trials to date:

  • How useful is it to rely solely on stomach hunger and fullness to create eating cessation? (Ikamuddin’14)
  • How will gastric stimulation stack up in more comprehensive comparisons to other treatments – such as diet, behavioral therapy, exercise? (Ikamuddin ’14; Dixon ’11).
  • We should be looking at response systems other than fullness, such as hedonic (pleasure) messages, for which treatment would be entirely different, less invasive, and possibly more long-lasting.
  • Cross-study between the medical mechanisms of obesity and the psychological/behavioral components is needed for optimum diagnoses – that is, which patients will benefit from which treatments – surgical, pharmaceutical, psychotherapeutic, and implant – or treatment combinations.

Why stress can make you fatter around the middle

Written by Dr. Ralph E. Carson on . Posted in Blog, Etc, From the Desk of Dr. Carson

As we have been seeing, those struggling with obesity are beset by many vicious cycles of fat begets fat. This self-fueling problem explains why only a slow, steady approach, accompanied by lifestyle changes that carry through the long haul, is the best solution. Another way that fat begets fat occurs in the area of belly fat. Studies paint an interesting picture on the nature of belly fat – its composition, and how it responds to stress, alcohol, fried foods, and processed foods, and how it increases. These studies shed light on why certain behaviors add to belly fat.

There are two different types of fat stores, the fat that forms a layer beneath the skin (called subcutaneous adipose tissue – SCAT), and fat that forms an apron around the belly, visceral belly fat. Within the body, and as a response to what you do on the outside (eat, exercise, undergo stress), these two types of fats act in very different ways. Subcutaneous fat can be exercised away much more easily than belly fat. This visceral belly fat receives more blood flow and is more responsive to cortisol than the subcutaneous fat deposited around the waist (beneath the skin).

The abdominal fat cell environment contains more nerves, more inflammatory and immune cells, has more testosterone (androgen) receptors, and produces a greater percentage of large fat cells (as opposed to greater numbers). It’s a lively, responsive cauldron of activity. As a consequence, intra-abdominal fat cells are more metabolically active, absorb and store more dietary fatty acids from circulation, and are less inclined to release fat during dieting (Ibrahim ’10).

The absorptive nature of belly fat is quite significant because these absorptive properties make belly fat more responsive to cortisol – the stress hormone. Stress increases the enzyme (11beta-HSD-1) that regulates cortisol in the belly.

What this means to the dieter, the average person watching his or her waist, is that when you add stress to excess belly fat, you get a chain reaction in which the 11beta-HSD-1 enzyme speeds up the conversion of inactive cortisone to active cortisol. And enough studies have shown that the over-expression of 11beta-HSD-1 in belly fat tissue results in a host of problems, not the least of which is more fat. The problems include an amazing fourfold cortisol receptor increase (greater sensitivity to cortisol), insulin resistance (glucose intolerance or the inability to utilize sugar appropriately) and central obesity (Kannisto ’04; Anderson ’02; Morris ’05).

Since the enzyme activity is higher in belly fat than subcutaneous fat, it explains how stress significantly increases girth (Tomlinson ’02).

It’s important to know what behaviors tend towards the creation of belly fat. And not just from the perspective of a waist watcher. We’ve also seen studies that connect belly fat to learning, memory, and decision-making.

Diet is not the solution!

Written by Dr. Ralph E. Carson on . Posted in Blog, From the Desk of Dr. Carson

48 clinical trials attest; diet is not the solution.

For the umpteenth time, researchers have published proof that no matter what diet a person chooses (Paleo, Wheat Belly, Atkins, Weight Watchers, Jenny Craig, NutraSystem, etc.), the chances for success are the same. Whether the plan focuses on low fat or low carbohydrate, the study, involving 48 clinical trials and 7000 patients, resulted in an average weight loss of 18 pounds over 6 months. From one diet program to another, the differences were minimal. Basically, the difference between Jenny Craig, Atkins, NutraSystem, and you name it, was not enough to matter. Among scientists, the study was confirming, leading scientists to conclude that there is nothing magical about cutting carbohydrates or fat or adding protein.

These findings are not particularly new, but with every new fad diet that bursts on the scene, there’s an implicit challenge to the conclusion. The more interesting and persistent question is why test subjects in the reviewed studies had begun to gain weight back by the one-year mark – to wit, in all 48 trials, the participants started gaining weight back by one year. This caused the authors of the study to call out the true challenge for diet research: the need to understand how people can maintain their initial weight losses.

A total mind-body-spirit solution

A total mind-body-spirit solution

The authors reached an obvious conclusion, that the best dietary plan is one you can live with for a long time (i.e. the rest of your life).

The long view should be considered when comparing ways to lose weight and gain health. Considering the long view means choosing an approach that gives you the fewest challenges. And though the medical community often focuses on shedding pounds as a goal-oriented metric for improving health among the the obese, the root of the problem is rarely found in weight loss and weight control. FitRx focuses on health and well-being rather than the number of pounds. We consider the gold standard for longevity is an approach that offers encouragement and insight on attuned eating, healthy choices, image empowerment, physical wellness, joyful movement, mindfulness, and stress reduction.

Am I hungry or just not full?

Pleasure Overrides “Fullness”

Written by Dr. Ralph E. Carson on . Posted in Blog, From the Desk of Dr. Carson

Hedonics trump homeostasis

There is a belief that tuning into physical and mental “fullness” signals, when eating, will decrease the likelihood of mindless over-consumption. However, “research is continually finding that regardless of how full a person may feel, the body is hard wired to chemically reward itself by overeating” when faced with highly palatable foods (*Monteleone ’12).  Two gut compounds are credited with causing us to indulge in goodies well beyond the point of caloric need. One of these is a stomach hormone called ghrelin, which helps regulate the motivation and drive to eat as well as the capacity to experience reward or pleasure.

The other is the endocannabinoid 2-AG (2-arachidonoylglycerol) which is involved also with appetite and drive to eat. When a person wants a particular kind of food, these chemicals team up to override the sense of fullness. In other words, we are programmed to stuff ourselves for a rainy day. In one study, individuals originally planned to eat significantly more of their favorite food, than they planned to eat of a bland or unappetizing selection, despite the feeling of being satiated. When participants ate their favorite food, their blood levels of ghrelin increased significantly and stayed high for as much as two hours post-ingestion. (*Monteleone ’12)


“The plasma levels of ghrelin and 2-AG increased during hedonic eating, with the favorite foods, but not with non-hedonic eating,” Science Daily said of Monteleone’s work.

After eating an unappetizing nutritionally equivalent item, the ghrelin levels went progressively down. Levels of the compound 2-AG decreased after eating both the favorite and the unappetizing food. However, exposure to and consumption of a favorite food allowed 2-AG levels to remain higher for up to two hours compared to the non-favorite food.

Many treatments for obesity attempt to curb eating by recreating the feeling of fullness, either mechanically or surgically. But the work of Monteleone and Mozes suggests that in dealing with binge eating behavior, a focus on the hedonic (pleasure-center driven) response will be more efficacious than a focus on “fullness.” (Monteleone ’12; Mozes ’12)

At FitRx, we use the technique of “attuned eating,” which approaches the problem from the angle of meal satisfaction rather than fullness. The distinction between these two hypotheses is important when looking at treatment facilities because they result in different treatment approaches.

Next time: Highly palatable foods trigger continuation of eating whether or not one is full or recently finished a meal.
