So, for my final post of 2012 I decided to highlight some of my favorite posts from this year (a couple from my blog and then those from others that I read). I'll start with others and then move to a couple of mine that I think are worth a second look...
Others:
Top 10 tips for running in the dark by Nutritionella
Making Fitness Fun by Lindsay's List
90 Second Breakfast sandwich by The Lean Green Bean (I'll have to try this with either G-F bread or none at all)
Hare Envy by Backatsquarezero
And probably my favorite of all at this point because she articulates exactly where I am
Mindy's Fitness Journey and there are no bad words in the video- just the bleeped one in the title ;)
Now, for me- I think my absolute favorite post that I wrote- that I have to keep rereading it myself is this one: Beautiful
and some motivational pins to end your 2012!

Live Fit Phase 3
Last year I started the Live Fit 12 Week Trainer and saw really great results after completing Phase 1 and Phase 2 (the first 8 weeks), then I had a leg injury that prevented me from completing the last phase. Also, I had gotten pretty lean in the first 8 weeks, so I felt okay waiting to finish.
To recap, here are some pics of the first 8 weeks, unfortunately I didn't get pictures of each week so these are the only ones I have to share. (Isn't it amazing how much better we can look with a tan?)
Now that I'm all healed, I'm starting Phase 3, the last 4 weeks of the Live Fit Trainer. The last phase focuses on high intensity interval training (HIIT) for maximum fat burning while maintaining the muscle you've gained. Also, there is "carb cycling" to help reduce fat. Because I'm already pretty lean and don't want to get too much leaner, I will probably continue eating the way I did during weeks 1-8, that is, every 3-4 hours, with "cheat meals" on the weekends and maybe a couple pieces of dark chocolate after dinner. I will reduce my sugar and caffeine intake, so I'll report back on how that goes.
I copied the information below straight from the Live Fit website so you can see an overview of the final phase of the program.

THE WORKOUTS
Are you doing the Live Fit Trainer? I'd love to hear about your experience in the comments below! If you're doing another program, please let us know about that too.
Closing one chapter....
This post is going to be a trip down memory lane for the year 2012- unfortunately the journey really only took place from June to the present time. However, there's still plenty of lessons learned in January-May. As we close down 2012 I compare it to a book- it's time to close the chapter in order to open a new one January 1, 2013.
So- here we go:
January-March- I learned that I actually enjoyed running- began the couch to 5K program and got almost all the way through it until....
March-May- life happened- end of the school year hit and I ran around like a crazy person until...
June- I went on a hike and had these pictures taken- no sense in beating a dead horse but it shocked my system- I decided it was time- time to get serious and start making changes. Took a spinning class for the first time and LOVED it. Began the couch to 5K program again
July- Started taking spinning and regularly and watched some weight melt off- by the end of July I had lost about 10 lbs but it looked like more.
August- School started and I worried about my schedule not allowing me to go to the gym- BUT it did and I made time.
September- went to Atlanta at the beginning of the month and that was the first visual proof of change. Went to a wedding toward the end of the month and pulled off a dress that had been hanging in my closet for a while (and got lots of compliments)
October- this was my first "run" where I participated in The Color Run in Nashville- I had a GREAT time- lots of fun and a good way to just do something healthy!
November- this month saw two races- my first "official" 5K in this particular journey at Dollywood (Light the Way) and my 5 mile Turkey Trot in Columbus, Ohio on Thanksgiving. I also decided to sign up for the Knoxville Half Marathon...
December- Jingle Bell Run here in Knoxville (I just realized I never actually posted a recap so here it is- 3.1 miles in 34:00 minutes- I cut 6 seconds off of my time) and then just today I ran my last "5K" of 2012. I signed up to do a virtual anywhere 5K and just resolve to run. It was a tad bit on the chilly side so I ended up on the treadmill and finished in 35:55. This goes back to my thought that I do better when people are around me.
So, here I am at the end of 2012- there are things I need to improve on- for example in the last month I have gained 4-5 lbs. So, obviously I am NOT where I need to be. BUT, in looking back, I can see lessons learned, perspectives gained, and a new lease on my life. For the first time in a LONG time I am happy to be where I am and doing what I am doing. The joy that is in me overflows from my relationship with Christ and knowing that He is giving me the strength to do what I should have been doing all along.

Getting Fit in the New Year
Hi all! I hope you had a beautiful Christmas and are ready to ring in the new year! Many of us have set fitness goals for ourselves and there's no time like the new year to start turning your goals into reality and your plans into action.
If you want to get yourself and your family healthier in the new year, this blog is for you. :) Last year, I wrote about Getting Started Getting Fit, Making Time to Workout, Time Management Routines, and Waking Up Early to Workout, all of which will help get you started and on your way to a more fit lifestyle. (Click the photo below to read the entire post).
I've also posted my most current workout routine, the Live Fit 12 Week Trainer. As the name suggests, it's a 3 month program that provides specific details about what to eat and when, the workouts to do, and proper supplementation. I completed Phase 1 and Phase 2 last year and am starting Phase 3 now. I'll share that last part of the program with you later this week.

If you're looking for healthy recipes, click on "FOOD" under my blog header. You can start your morning with Protein Pancakes (my son requests them quite frequently) or a Breakfast Egg Sandwich.
To see how I prepare 10 meals in advance so they're ready to go for a quick lunch or dinner, you can read Food Preparation Day and then try out my favorite Tex Mex dish (it's made with extra lean ground turkey and is delicious!). Making meals in advance is the only way I can guarantee that I eat real home-cooked (not processed or pre-packaged) food every four hours. My Protein Brownies are a yummy snack with only about 100 calories. And I'm sure we can all start drinking more clean water. To make your water more fun, why not keep some Spa Water on hand?
Finally, I'm so thankful to have contributing food writer Jennifer of The Chronicles of Home bringing you healthy recipes every other Thursday. I especially love her food photography- so pretty! Check out her Butternut Squash & Lobster Risotto, Black Beans & Rice with Apple Slaw, and Multigrain Buttermilk Pancakes.

Britt Nicole- Stand-
When I feel like giving up
When my heart has hurt too much
Feels like i've reached the end
No, I won't turn and run
This battle will be won
When I've done all I can
I stand, stand, stand
When my heart has hurt too much
Feels like i've reached the end
No, I won't turn and run
This battle will be won
When I've done all I can
I stand, stand, stand
Matt Redman- 10,000 Reasons (Bless the Lord)

Bless the Lord, O my soul
O my soul
Worship His holy name
Sing like never before
O my soul
I worship Your holy name

You are the healing in my heart
When all that I can see are broken memories
You are the light that's in the dark
Chorus:
You are the song,
You are the song I'm singing.
You are the air,
You are the air I'm breathing
You are the hope,
You are the hope I needed.
Ohhooohh
**I saw a survey like this on another blog (one that has more questions and is designed to be more personal) but I cut out some of the questions and decided to use them to bring my 2012 in review.

Wondering What to Practice at Home? Consider a Private Lesson
by Timothy
In a recent post Home Practice: The Best Way to Improve Your Health and Well-Being, I wrote about the value of a regular home practice. Practicing at home is particularly important for people with a medical condition who can’t do (or at least probably shouldn’t be doing) most public classes. But medical condition or not, the question remains, which yoga practices should you be doing at home?
One of the best ways to find the answer is to get a private yoga lesson. As it turns out, yoga goes about prescribing home practice in a very different manner than doctors prescribe medications or other treatments. In western medicine, we always try to diagnose the condition first, and then give drugs or other treatments to address that problem. If we can’t diagnose the condition, then all we can do is give treatments to relieve the symptoms.
In yoga therapy, the western medical diagnosis certainly can influence the treatment, but it’s only one of the many factors we consider. Two women, for example, may have the same diagnosis of Stage 1 breast cancer, and would likely get very similar recommendations from their doctors about how to treat it. But the appropriate yoga approach (used as a complement to medical therapy) might vary a lot depending on how fit they are, how much yoga they’ve done (and what styles), how much time they have to dedicate to their practice, how spiritually oriented they are, and so on.
Good yoga teachers always consider the broader context. When I evaluate a student, after interviewing them, I often start out by looking at them structurally. How is their posture? Are their shoulders rounded? Is the head forward of the spine? Are they stiff or flexible? Are there certain joints that are giving them problems, and, if so, how well are the bones on either side of those joints aligned?
After structure, I tend to move onto the nervous system (and breath, since the two are intimately linked). Are they suffering from excessive stress? Agitated? Sleeping poorly? Can’t get out of bed? What’s the balance of the sympathetic nervous system (fight or flight) vs. the parasympathetic (rest and digest)? Is their breathing smooth and deep or is it shallow and choppy? Is it primarily in the upper chest or does the abdomen move out and in with each breath?
In a similar manner, I evaluate each student’s balance as seen through the lens of Ayurveda, India's indigenous holistic medical system, as well as their psychological functioning and such spiritual matters as their level of joy, compassion and fulfillment. In my Yoga as Medicine workshops, we divide our student assessments into five categories, using the acronym SNAPS: Structural, Nervous system, Ayurveda, Psychological, and Spiritual. Each student winds up with a different constellation of findings, which we then try to address with the yoga routines we recommend.
Although I developed the SNAPS protocol to use on people seeking yoga therapy, the same process can help determine a good routine for someone who is simply interested in using their yoga as preventive maintenance, to build strength and flexibility, or to work off some of life’s inevitable stressors.
Say a student looking for a home practice has a slumping posture, a restless mind, shallow upper chest breathing, and an increase in the Ayurvedic dosha of vata or air (see my post on vata, Autumn, Healthy Aging and the Ayurvedic Dosha Vata). If I considered only structure and breathing in developing her routine, I might think that focusing on backbends would be helpful. But too many backbends, or more intense ones, like full Wheel pose (Urdhva Dhanurasana), could increase her mental agitation and push her vata further out of whack.
Perhaps I would end up settling on some gentle, restorative backbends done over folded blankets to open her shoulders and chest, while simultaneously allowing her to rest physically and mentally. I might also recommend daily alternate nostril breathing to balance her nervous system, and quiet her mind to the point that seated meditation would be more effective. Often, we reach the final recommendations based on trial and error, for example, putting the student in a potentially helpful pose and seeing what it looks like and how it feels. Maybe we change the blankets a bit and look again or try a different pose entirely.
What I am describing is what a good yoga teacher or therapist would do in a private lesson. Not everyone can afford a private lesson (price varies based on the experience of the teacher, the length of the session and the geographical area), though some teachers have a sliding scale, or take on a few cases as karma yoga for those in need. But once you get home, yoga is free, of course, so a lesson could end being cheaper than a series of classes. (If you don’t know a suitable yoga teacher or therapist in your area, check out the database of the International Association of Yoga Therapists at iayt.org.)
Although science has yet to test the idea, it is my belief that a well-designed practice tailored just for you will likely be better than a standardized protocol used in a study or a sequence printed in a magazine. All those approaches, good as they may be, are determined without ever laying eyes on the student—and that’s simply not the best yoga has to offer.
To me, it’s a testament to the power of yoga that so many people are helped by these one-size-fits-all yoga fixes. However, to most of us working in the field, there is little doubt that a tailored approach can be safer, more efficient, and much more effective. As a scientist, I’m all for testing these notions, but yoga research hasn't progressed to the point where such studies are being done (or funded). In the meantime, my advice is, whenever possible, to tailor your practice now, and ask questions later.
Even if you don’t have a medical condition, working one on one with a teacher can help you create the home practice that suits your particular body, needs, and goals. And if such a tailored approach moves you more efficiently in the direction you’d like to go than an off-the-shelf routine, you’ll likely notice the benefits and be more motivated to stick with it. And that, of course, is the key to success in yoga.

The 2012 Atherosclerosis egg study: More smoking is associated with more plaque, unless you eat more eggs
I blogged before about the study by David Spence and colleagues, published online in July 2012 in the journal Atherosclerosis (). This study attracted a lot of media attention (e.g., ). The article is titled: “Egg yolk consumption and carotid plaque”. The study argues that “regular consumption of egg yolk should be avoided by persons at risk of cardiovascular disease”. It hints at egg yolks being unhealthy in general, possibly even more so than cigarettes.
I used the numbers in Table 2 of the article (only 5 rows of data, one per quintile; i.e., N=5) to conduct a type of analysis that is rarely if ever conducted in health studies – a moderating effects analysis. A previous blog post summarizes the results of one such analysis using WarpPLS (). It looked into the effect of the number of eggs consumed per week on the association between blood LDL cholesterol and plaque (carotid plaque). The conclusion, which is admittedly tentative due to the small sample (N=5), was that plaque decreased as LDL cholesterol increased with consumption of 2.3 eggs per week or more ().
Recently I ran an analysis on the moderating effect of number of eggs consumed per week on the association between cumulative smoking (measured in “pack years”) and plaque. As it turns out, if you fit a 3D surface to the five data points that you get for these three variables from Table 2 of the article, you end up with a relatively smooth surface. Below is a 3D plot of the 5 data points, followed by a best-fitting 3D surface (developed using an experimental algorithm).
Based on this best-fitting surface you could then generate a contour graph, shown below. The “lines” are called “isolines”. Each isoline refers to plaque values that are constant for a set of eggs per week and cumulative smoking combinations. Next to the isolines are the corresponding plaque values. The first impression is indeed that both egg consumption and smoking are causing plaque buildup, as plaque clearly increases as one moves toward the top-right corner of the graph.
But focus your attention on each individual isoline, one at a time. It is clear that plaque remains constant for increases in cumulative smoking, as long as egg consumption increases. Take for example the isoline that refers to 120 mm2 of plaque area. An increase in cumulative smoking from about 14.5 to 16 pack years leads to no increase in plaque if egg consumption goes up from about 2 to 2.3 eggs per week.
These within-isoline trends, which are fairly stable across isolines (they are all slanted to the right), clearly contradict the idea that eggs cause plaque buildup. So, why does plaque buildup seem to clearly increase with egg consumption? Here is a good reason: egg consumption is very strongly correlated with age, and plaque increases with age. The correlation is a whopping 0.916. And I am not talking about cumulative egg consumption, which the authors also measure, through a variable called “egg-yolk years”. No, I am talking about eggs per week. In this dataset, older folks were eating more eggs, period.
The correlation between plaque and age is even higher: 0.977. Given this, it makes sense to look at individual isolines. This would be analogous to what biostatisticians often call “adjusting for age”, or analyzing the effect of egg consumption on plaque buildup “keeping age constant”. A different technique is to “control for age”; this technique would be preferable had the correlations been lower (say, lower than 0.7), as collinearity levels might have been below acceptable thresholds.
The underlying logic of the “keeping age constant” technique is fairly sound in the face of such a high correlation, which would make “controlling for age” very difficult due to collinearity. When we “keep age constant”, the results point at egg consumption being protective among smokers.
But diehard fans of the idea that eggs are unhealthy could explain the results differently. Maybe egg consumption causes plaque to go up, but smoking has a protective effect. Again taking the isoline that refers to 120 mm2 of plaque area, these diehard fans could say that an increase in egg consumption from 2 to 2.3 eggs per week leads to no increase in plaque if cumulative smoking goes up from about 14.5 to 16 pack years.
Not too long ago I also blogged about a medical case study of a man who ate approximately 25 eggs (20 to 30) per day for over 15 years (probably well over), was almost 90 years old (88) when the case was published in the prestigious The New England Journal of Medicine, and was in surprisingly good health (). This man was not a smoker.
Perhaps if this man smoked 25 cigarettes per day, and ate no eggs, he would be in even better health eh!?

Each isoline refers to plaque values that are constant for a set of eggs per week and cumulative smoking combinations. Next to the isolines are the corresponding plaque values. The first impression is indeed that both egg consumption and smoking are causing plaque buildup, as plaque clearly increases as one moves toward the top-right corner of the graph.
But focus your attention on each individual isoline, one at a time. It is clear that plaque remains constant for increases in cumulative smoking, as long as egg consumption increases. Take for example the isoline that refers to 120 mm2 of plaque area. An increase in cumulative smoking from about 14.5 to 16 pack years leads to no increase in plaque if egg consumption goes up from about 2 to 2.3 eggs per week.
These within-isoline trends, which are fairly stable across isolines (they are all slanted to the right), clearly contradict the idea that eggs cause plaque buildup. So, why does plaque buildup seem to clearly increase with egg consumption? Here is a good reason: egg consumption is very strongly correlated with age, and plaque increases with age. The correlation is a whopping 0.916. And I am not talking about cumulative egg consumption, which the authors also measure, through a variable called “egg-yolk years”. No, I am talking about eggs per week. In this dataset, older folks were eating more eggs, period.
The correlation between plaque and age is even higher: 0.977. Given this, it makes sense to look at individual isolines. This would be analogous to what biostatisticians often call “adjusting for age”, or analyzing the effect of egg consumption on plaque buildup “keeping age constant”. A different technique is to “control for age”; this technique would be preferable had the correlations been lower (say, lower than 0.7), as collinearity levels might have been below acceptable thresholds.
The underlying logic of the “keeping age constant” technique is fairly sound in the face of such a high correlation, which would make “controlling for age” very difficult due to collinearity. When we “keep age constant”, the results point at egg consumption being protective among smokers.
But diehard fans of the idea that eggs are unhealthy could explain the results differently. Maybe egg consumption causes plaque to go up, but smoking has a protective effect. Again taking the isoline that refers to 120 mm2 of plaque area, these diehard fans could say that an increase in egg consumption from 2 to 2.3 eggs per week leads to no increase in plaque if cumulative smoking goes up from about 14.5 to 16 pack years.
Not too long ago I also blogged about a medical case study of a man who ate approximately 25 eggs (20 to 30) per day for over 15 years (probably well over), was almost 90 years old (88) when the case was published in the prestigious The New England Journal of Medicine, and was in surprisingly good health (). This man was not a smoker.
Perhaps if this man smoked 25 cigarettes per day, and ate no eggs, he would be in even better health eh!?

Friday Q&A: Death of a Student
Q: I am a yoga teacher on the East Coast & have been teaching for 6 years. Last week, I found out a young student in one of my gym classes died (suicide, 2 weeks ago). He had been attending this class fairly regularly for the past 2+ years. The class is small, but it is not the type of environment where the students have developed close relationships with one another. They show up, practice & leave (it’s an evening class). We would have a few minutes before class to sit & wait for the earlier class to finish, but that’s the extent of any interaction that I’m aware of taking place.
I am struggling with whether or not I say anything to the group or let it go. He occasionally attended the class with a young woman, who it seemed he knew from outside of class, but I'm not sure how.
Any words of wisdom would be appreciated!
A: Firstly, let me express my sadness at your loss. Although I have not lost any students to suicide, I have had students who died suddenly, and found I was impacted by the loss more than I would have anticipated. Then, of course, there are two questions that seem to arise: Do I share this with the rest of the class? And, from a teaching perspective, how do I cultivate community in settings where it does not yet exist in a very tangible form?
I don’t think there is right answer to the first question, as many variables might influence the decision to tell the group of the death of a fellow student. But I, too, teach in a gym setting twice a week and have done so for almost 10 years now. I sometimes feel a lack of community there as well, although in reality, I have some students who regularly attend these classes, some for many years. Remembering this encourages me to speak with this group in the same way I do my studio students where community is perhaps more obvious. And every time I do share some difficult or personal information that has some relevance to our work together, I am invariably delighted with the feedback that I receive, and the interactions amongst the students that ensue. So, if you’d like a greater sense of community, situations like this and many others are perfect ways to get students connecting in ways beyond just their asana, pranayama and meditation practices.
One of my favorite sutras, which I have probably alluded to before, but which has some relevance here, is 1.33, where Patanjali gives some of the only guidance in his collection of sutras about how to behave and interact with one another.
1.33. By cultivating friendliness towards happiness and compassion towards misery, gladness towards virtue and indifference towards vice, the mind becomes pure.
Here Patanjali suggests practicing compassion, karuna, when encountering suffering (misery in this translation), dukha. How one applies that, he does not say, but the reality of this loss to suicide, shared and discussed openly, may have the beneficial effect of making all of your students feel more connected, less lonely, and perhaps could conceivably prevent another such loss. All the best to you, your students and all of our readers this holiday season!

The Holidays, Hormones, and Happiness
Lots of changes this year with the family and how this Mom/Trainer will be spending the Christmas Holiday…all good, but different. It feels weird for me having to adjust to the changes in life and not just for the holidays, but with my hormones. Thanksgiving month was the start of struggle with marked and increased changes to that which I can only attribute to transitioning into another part of womanhood…OH MY! I mean really…all at the same time…during the holidays…really, really???
I was already having a bit of a time adjusting to the changes occurring with how the holidays would have to be split up as a Mom of adult kids that have their own new agendas…bitter sweet happiness…but still a big adjustment. Mixed in with the throws of hot flashes, high anxiety, other personal changes, irritability due to sleep deprivation, just not feeling like ME…GEEZ…the pumpkin seeds just are not cutting the mustard anymore…lol…and for heaven’s sake watermelon season is long gone. I am so blessed to have such a supportive husband through this journey and hats off to all the other husbands out there that are understanding and do not take personal all the goings on of menopausal issues…GOLD STARS!
I am such a faith person and celebrate what Christmas means to me as a woman of God, but let me tell you, I have had to have more than a few one on one conversations over the last two months. Life can feel overwhelming when hormonal changes are occurring and YES…although I am usually springing about happy as a clam during the cherished holiday season…it just has not felt the same this year. I understand that it is probably the combo of everything happening at the same time, but YIKEE. It is even more awkward that I can’t even offer up a good explanation for feeling high anxiety…I already have an A1 personality type anyway which probably does not help. On top of that, what the heck happened to my energy, stamina, and everything else that felt like Darla…I mean come on now…this is a double REALLY, REALLY?
OK…I am sharing some very personal things right now and please do not confuse it for complaining…I am letting you know that I, just like you, go through life, experience what every woman of a young, fit almost 50 can go through and it can SUCK. YES…I said it…some days, it really sucks to not feel like ME…my plug has been pulled right out of the wall and I am holding onto the cord going OK…now what? You know me…I do not let things get the best of me…so more research was in order and a trip to the doctor. I have worked with many women who experience peri-menopause and menopause symptoms and although I suspected that this was indeed the culprit invading my inner body space, I needed to rule out the possibilities of medical issues not related. Believe me, I would have hit the floor with a positive pregnancy test…love babies, love my children, am a grandmother…but that would have definitely sent me to the peri-menopausal special place for TLC. Whew…negative…let’s move on and off that subject.
The beautiful thing about life is that we all experience different things when it comes to reaching menopause…some sail through without a scratch, while others, and that would include me, do not necessarily care for the changes that are happening through the process. So, through my research, I am giving a natural herb blend menopausal support supplement a try and am hopeful for a positive result after reading the reviews, understanding each herb independently and the possible benefits/negatives to the body. The next few months will tell me if I need to take a different direction, but I will keep a positive outlook and in conjunction with the transdermal hormone creams that I use now, what do I have to lose. I will let you know how it goes a couple of months into my herbal therapy.
What a subject to write about during the holidays, but HERE IT IS…out of my control, happening right now, and Merry Christmas Darla…ho ho ho. One of my fabulous clients shared “look at it this way…you will be able to wear white pants now”. I had to laugh…she was right…love my clients. As much as I motivate them, there are days that they motivate me without their even knowing it. I say, I really enjoy my strong coffee in the morning right now too…especially after a night of visits from the” flash club”. This is a part of my life that I have no control over, except for the introduction of herbal supplements, but that truly does not change that I am changing. Acceptance of again, the New Modified Me, feels like it needs to repeat itself through my menopausal journey. Technically, I will not be in true menopause until I have not had a cycle for a year…WHAT??? Ughhh…so, I can be out and about in my new WHITE PANTS and still be surprised…OH FA LA LA LA LA…JOY JOY JOY JOY.
Honestly, it can feel unfair, but I have experienced all kinds of unfairness in my life, AND all circumstances have been used to grow me in a positive way to be a BETTER, STRONGER, and even MORE FAITHFUL person. So, I will look upon this part of my life in the same way, and I CHOOSE TO BE HAPPY. In fact, I am HAPPY and have so much to be thankful for with my health, meeting the man I can truly say I LOVE and understand fully what that means and feels like, my children, family, friends, clients, and even the fact that I have a roof over my head and a warm bed to sleep in…more than HAPPY…I am humbled and thankful. So, when the overwhelming Life is Bigger than ME Menopausal Monster tries to creep into the crevices of my mind and body, I will try really hard to concentrate on all the things positive in my life. This is in fact a journey that will require patience and TLC, and I know that some days will be more challenging than others, but I also realize that even this experience will enable me to help others, and through that, I will be blessed.
HAVE A VERY MERRY CHRISTMAS and Stay Healthy~
