Princess Health and Brown Fat: It's a Big Deal. Princessiccia

Princess Health and Brown Fat: It's a Big Deal. Princessiccia

Non-shivering thermogenesis is the process by which the body generates extra heat without shivering. Shivering is a way for the body to use muscular contractions to generate heat, but non-shivering thermogenesis uses a completely different mechanism to accomplish the same goal: a specialized fat-burning tissue called brown fat. Brown fat is brown rather than white because it's packed with mitochondria, the power plants of the cell. Under cold conditions, these mitochondria are activated, using a specialized molecular mechanism called uncoupling* to generate heat.

The mechanism of brown fat activation has been worked out fairly well in rodents, which rely heavily on non-shivering thermogenesis due to their small body size. Specialized areas of the hypothalamus in the brain sense body temperature (through sensors in the brain and body), body energy status (by measuring leptin and satiety signals), stress level, and probably other factors, and integrate this information to set brown fat activity. The hypothalamus does this by acting through the sympathetic nervous system, which heavily innervates brown fat. As an aside, this process works basically the same in humans, as far as we currently know. Those who claim that rodent models are irrelevant to humans are completely full of hot air**, as the high degree of conservation of the hypothalamus over 75 million years of evolution demonstrates.

Two new studies concurrently published in the Journal of Clinical Investigation last week demonstrate what I've suspected for a long time: brown fat can be 'trained' by cold exposure to be more active, and its activation by cold can reduce body fatness.

Princess Health and Zucchini: The Home Gardener's Worst Friend? With bonus garden-related rambling.. Princessiccia

One of my main gardening goals has been to harvest more of something than I can eat, despite my limited gardening space here in the Emerald City. I want the feeling of abundance that comes with having to preserve and give away food because I can't eat it all.

Enter zucchini. My grandfather used to say that in New Jersey in summertime, you'd have to keep your car doors locked, otherwise the car would be full of zucchini the next time you got in! In mid-May, I planted two starts from my local grocery store labeled "green zucchini", with no further information. I put them in a bed that used to be a pile of composted horse manure, and that I had also cover cropped, mulched, fertilized, and loosened deeply with my broadfork. They look pleased.

Princess Health andH+P Racing: July 20th-21st, 2013.Princessiccia

It was a quiet weekend for running, but a huge weekend for triathlon for a number of H+P athletes.  Here are the results:

Toronto Triathlon Festival (National Championships)

Florian Ong hammering on the bike

Florian Ong did quite well despite only starting to swim last fall.  He came in 17th place in his age group, averaged well over 38km/h on the bike and ran a low-38 minute 10K.

Kristen Marchant (who trained with us last summer) also had an amazing, break-through performance.  She actually WON the event, posting an epic sub-38 minute 10K.  Kristen is now the female National Champion!


Belwood Triathlon

Luke showed once again that despite training for Ironman, there is still lots of speed hidden in those legs.  He ended up winning his AG, placing 3rd overall, and actually being the first age-grouper to cross the line!  Full results.

Blue Water Triathlon

Ed Cyr really impressed in one of his final tune-up races before Ironman MTB.  He reached a new personal best on the 40K bike (averaging just under 41km/h) and 10K run off the bike (just over 37 minutes).  He also placed 3rd overall, great work! Click for full results.

Princess Health and The Genetics of Obesity, Part III. Princessiccia

Princess Health and The Genetics of Obesity, Part III. Princessiccia

Genetics Loads the Gun, Environment Pulls the Trigger

Thanks to a WHS reader* for reminding me of the above quote by Dr. Francis Collins, director of the US National Institutes of Health**. This is a concept that helps reconcile the following two seemingly contradictory observations:
  1. Roughly 70 percent of obesity risk is genetically inherited, leaving only 30 percent of risk to environmental factors such as diet and lifestyle.
  2. Diet and lifestyle have a large impact on obesity risk. The prevalence of obesity has tripled in the last 30 years, and the prevalence of extreme obesity has increased by almost 10-fold. This is presumably not enough time for genetic changes to account for it.

Princess Health and Return to the Source Parkour Camp. Princessiccia

For those who are interested in natural movement training, this summer my friend Rafe Kelley will be hosting an interesting three-day event near Bellingham, WA called "Return to the Source".  Rafe is skilled in a variety of movement disciplines and is the co-founder of the Seattle parkour gym Parkour Visions.  Parkour is a very fun sport that hones our natural ability to skillfully navigate physical obstacles, but it's usually done in an urban context.

The camp will take place from August 23-25.  Here's a description from the Parkour Visions site:
"This summer, return to the source of human movement with Parkour Visions as we explore the natural environment in and around Bellingham, WA. Rafe Kelley will introduce you to the benefits of training and playing in nature. You will learn how to adapt your technique and movement to moving effectively through woods, over rocks, and in trees during this unique, 3-day experience."
Watch this video if you want to see what you're in for.

Knowing Rafe, it will be fun and productive.  You can sign up through this page.

Princess Health and How To Stay Committed To Exercise?. Princessiccia

Do you know anybody who started exercising full of hopes and then gave up after a short while? Or maybe this has happened to you too? We are human beings and very easily getting tempted to change our plans when we are not committed to something.

Let's see few easy-to-follow tips to make sure you stick to your exercise routine:

1. Make a regular workout schedule

You might be a morning person or an evening person when it comes to exercising. It doesn't matter.
What matters is that each week you should put the days and times in your diary when you plan to exercise. Take it as seriously as you would take an important meeting or interview. Make changes, organize around to make sure you have those times free for exercising.

Try to plan it in a time-saver way if you have a busy schedule: in the morning on the way to work; in the afternoon/evening on the way home from work. 

One hour workout is only 4% of your day, so this is something you should definitely be able to fit into your busy schedule. 

You know yourself. If you find it difficult to get out once you arrived home, then take your sports gear with you in the morning, jump in to a class the way home, and you're done. If you prefer going home, preparing a dinner, then going out for a jogging or a class before going to bed, then find a late class, and do that.

The most important is to write it down in your diary, and take it seriously.

2. Set a goal

This goal shouldn't be a weight loss goal. Why? Because weight loss is a result of a complex life-style change: making changes both in your diet and in your exercising habits. 

That goal should be something measurable: if you only start working out now, let's say your goal is to exercise one ore two hours a week. Later you can increase this gradually.

Your long term goal could be something as better sleep, less stress, avoiding illnesses . You can have weight loss as your long term goal, but make sure you don't expect the miracle to happen overnight. The healthy weight loss is 1-1.5 kg per week, but not more than 2 kg a week. Your body, your skin needs to adjust to the 'smaller you', so be patient, don't plan to lose lots of weight in a week. Also, as I said before, you need to have a closer look at what you eat if your goal is to lose weight.

3. Fun and/or variety

Many people say they don't like working out. This is only because they haven't tried enough types of exercising to find what they really love. 

Some people can unwind while jogging, others find jogging boring. Some people can truly get energized while swimming, others don't like being in water. Some people feel uncomfortable in a group class, others find it the only workout they enjoy.

Never feel uncomfortable just because you don't like the type of workout others love to do. There is nothing wrong with you!

Go and try out new things, and stick to the one you enjoy, the one you are looking forward to. You might find new exercise-buddies, people alike, who enjoy the same exercise you do.

After finding the first type of exercise you love, and getting committed to it, soon your body will crave more.
Start on a gradient, find the one you enjoy first! 

4. Two short lists you'll need

Even when you like your exercise, there are days when it's just too hard to push yourself to go. The weather is too warm or too cold; your boss was horrible; there are too many things to do at home... and so forth... When you don't feel like working out, that's when you need it most!

So in order to push yourself through those difficult times, here is what to do.

Sit down after your next workout when you feel great, and write down:

a/. 3 things you like about your exercise routine (For example: This is the only 'Me-time'  the whole day. I feel more confident in my body after working out. I feel like eating healthier after a workout.)

b./ 3 benefits of exercising (For example: I sleep better after exercising. I always calm down after a stressful day during working out. I have more energy for the rest of the day after exercising.)

Keep this list some place you can always reach (your wallet, your diary, etc.). The next time you don't feel like doing anything, read the list you wrote, and I'm sure you'll put your runners on immediately.

5. Things that can put you off exercising

a/. Focusing on the scale

Your body needs time once you start exercising. Plus, muscle is heavier than fat. So while you get rid of fat and your muscles get stronger, while you look better and better,  you might not notice any change on the scale. Forget about the scale! Don't even step on it! Just believe what you feel, and what you see in the mirror!

b./ Working too hard

You might wake up on a morning and say: "I start exercising from today." And you are so enthusiastic that you start a strenuous workout routine, every day. Then few weeks gone and you find yourself sitting on the couch again.

After a long break you always have to be patient with yourself and with your body. What you missed in a few months or years cannot be done in a week or two.

Don't feel uncomfortable taking it easy when joining a group exercise class, it is okay to take short breaks during the class. Don't forget, everyone felt the same way you feel now at some stage. If you really want to get there, be patient!

c./ Comparing yourself to others

This relates to the previous point. You join a gym, or a group class, and feel that everyone else looks better, knows better, works better and harder than you. You go running and feel like everyone is looking at you and everyone thinks you are very slow.

Never compare yourself to others!

Every human being is different, and each and every body is different. Plus, those people seemingly working harder started one day and felt the same way you're feeling now. But they didn't give up!

So don't be shy, be proud of yourself! Many people sitting on the couch would admire you! Focus on your goal, and do your workout like nobody is watching. 

And one more thing: Did you stop exercising for a while and now feeling bad about yourself? The more you think, the more time will pass. It can happen to all of us! All you need to do is get your sports gear, and start again!
