[03/01/15]   New research is showing the Intermittent Fasting may increase longevity by increasing the expression of genes that have been shown to be associated with a longer lifespan!

[02/25/15]   Recently I had a client who had lost around 10 pounds on their own but then fell off of the wagon and was mentally and emotionally in a bad place because of this. This caused her to go back to her old ways of not exercising and eating out more often. Before she knew it she had gained her weight back AND MORE! She came to me completely distraught looking for answers. I sat down with her, talked to about her issues, refocused her, reminded her of her goals, and gave her a full plan to get there. Well, 2 months later I am proud to say she has lost 20 pounds, 14 inches and 5% body fat and is still going strong. I may only work with her one day a week but I make sure to contact her throughout the week to keep her motivated and keep her on track.

I am so happy for her and just wanted to share her story!

[02/23/15]   One of the best ways to boost happiness............ do something kind for someone else! Now that sounds like a great idea, if only more people did this when upset instead of taking their anger out on something or someone else

[12/06/14]   When it comes to the debilitating disease, osteoporosis (porous bones), many individuals are advised to take vitamin D and high doses of calcium. As one who had to diagnose issues with commercial aircraft avionics and ground based radar systems, I was trained to consider every link in the chain. With this in mind let us consider a few additional links in the chain for bone health.

- Magnesium activates vitamin D to absorb calcium. It is also one of the building blocks for bone structure and density.
- Vitamin D gives you the ability to absorb large amounts of calcium.
- Calcium is a core building block for bones, teeth, and other tissues.
- Vitamin K2 activates proteins that bind calcium to your bones, and protects your arteries from hardening due to calcium buildup.
- Potassium is directly associated with bone mineral density, yet most people consume less than half of their daily requirement. You need roughly 4000 mg every day. If you drink a lot of water and/or exercise intensely, you need even more (low sodium V8 and coconut water are packed with potassium).
- Zinc has a restorative effect on bone loss and increases bone mass.
- Taurine enhances bone tissue formation and retards bone loss.

Give your body the raw materials it needs to keep you healthy and strong for decades to come.

[11/05/14]   In spirit of the local elections today lets have a little vote :-)

What is your favorite type of workout?

1. Circuit Training ( one exercise followed by another and another with limited rest)
2.Bodybuilding style (various rep ranges with shorter rest periods and focus on tension on the muscle)
3. Powerlifting style ( heavy weight for lower reps mixed with speed work with submaximal weights lifted for speed)
4. Crossfit ( huge variations but most commonly a certain amount of repetitions of various exercises performed in the fastest time possible or as many rounds of a circuit of exercises in a given time.)
5. Cardio only (eww)

[11/02/14]   The best question is not what is the best trainer designation or certification, but who is the best trainer for you? Recommendations of others is a good start, but successful training relationships may be most dependent on a good relationship between you and your trainer. Do you believe your trainer? Do you like them? Do they motivate you? Most exercise programs will get results if performed consistently over time. Often the basics are enough. But few routines will get performed consistently over time without confidence in the trainer.

I believe this is one of many reasons that sets me apart from others. I am able to connect with my clients and help them get the results they desire.

[11/01/14]   PLEEEEEASE READ!!!

PTDD, Post Traumatic Diet Disorder is a term that was used recently describing the state of “chronic dieters” in our western culture today. The amount of people who struggle with weight after a diet and continue to try different “diets” for the remainder of their lives is insanity…and quite sad to say the least. Its a self punishing tool that becomes so ingrained that people don’t even see it as such any more. It appears to be the quick fix solution that offers it all : hope, confidence, health, energy, freedom, happiness, and beauty….

A diet can be described as “nothing but a TRAUMA” !(‘The Globe and Mail ,BC Edition’ – 2014-08-11

Every diet includes a self sabotage system which begins with a fast or restriction of some kind, an element of under-eating, over exercise, calorie counting, obsessive mirror checking, daily weigh in’s, and of course the almighty gold star at the end of the day for a job well done…or that dreaded black X. The most insane part about all of this is that DIETS DON”T WORK and leave the individual feeling defeated, exhausted and starving!

The result is what has been described as Post Traumatic Diet Disorder, whereby human beings are living in fear of food. People are left confused and devastated when they gain all the weight back after the” successful “diet and are left to the only possible conclusion…they didn’t do it well enough, they didn’t try hard enough…they simply are not “enough.

“Diet failure” mentality has lead to insecurity, a loss of hope and depression amongst millions and yet, as a culture we are still caught up in this idea. Diet comes now under new, more hip “code” words such as “cleanse”, “fast”, or ” way of life”. New “organic” extreme eating methods are all the rage and are even trendy in high school and amongst pre-teen children! Society is obsessed with “skinny” and people younger and younger each year are becoming afraid to eat!

This interplay on words DIET and TRAUMA are nothing show of brilliant in my opinion. Diets do nothing but create an ongoing self defeating story of defectiveness. I am in full agreement with Freedhoff’s recommendation to this self induced trauma: to embrace our humanness, and accept our own unique bodies as well as committing to a journey of self love, without restriction.

The following are some simple steps for a problematic eater to begin just that:

1. Throw Away the Scale- Using a scale to determine how ” good” you are is only adding to the negative self talk and only creates more of a division between your ability to trust yourself and your connection with your own body. Let it go- its just not important.

2. NEVER Skip a Meal -This is a big one and I don’t think I can stress the importance here enough. Eat breakfast within 20 minutes of getting up and never skip a meal in the day. If you have a “slip up” with food in the day, just get right back on track at your next meal.

3. Save the Cleanses and Detoxes for Somebody Else-.This is a “diet in disguise” for a problematic eater. If you are someone who struggles with eating “normally” then its best to leave the extreme health trends to others.

4. Plan your Meals- NOT “DIET “YOUR MEALS ! - This is an important step that is often confused with “dieting”. A food plan is simply having an idea what your day around food will look like.

5. Re- Vamp your Inner Perfectionist Thinking- Looking at the THINKING that is creating your problematic eating is especially important for long term healing. Write the negative thoughts down with an affirmation that you believe to be true for each thought. Repeat until that thought looses its edge and the anxiety passes.

Learning to live without the should’s, the restricting, and the inner perfectionist is a journey. Be gentle and trust that you absolutely can heal FOR LIFE. This has been my experience- there truly is a solution.
