Body Systems

Choosing the right strategy to improve body composition is a hot topic, with many different exercise and dietary strategies suggested to be successful for weight loss, reducing body fat, and preserving lean muscle mass. It is important to select the right approach that fits your individual needs. It is particularly encouraging that many studies show success in improving body composition with as little as three, thirty-minute workouts per week, provided they are combined with a diet regimen that is calorically neutral or hypocaloric[i]. These small studies have not only looked at exercise type but have included a variety of individuals

Our muscles are capable of amazing, precise and coordinated force; from lifting a teacup to explosive movements such as sprinting and power lifting. Muscles allow for tremendous function so that we can explore our full physical potential. Approximately 40% of our body is composed of skeletal muscle but there are several other types of muscles including smooth and cardiac muscle (Guyton and Hall 2006). There are almost 700 individual muscles in your body and they come in all shapes and sizes (Tortora and Grabowski 2003). The smallest skeletal muscle in your body is located in your middle ear and is

The importance of the digestive tract, also called the gastrointestinal tract (GIT), is often underestimated. Its purpose may seem to only digest food, absorb nutrients and then excrete waste; however, the world inside the GIT is actually an entire ecosystem, and one that constantly influences our health. The bacterial colonies within this system uses the food we send down, producing nutrients and neurotransmitters, sending signals, influencing inflammation and the immune system, and interacting with the nervous system. There are literally trillions of living microorganisms inside the gut and throughout the digestive system with the power of suggestion over our mood.

By Dr. Sarah Zadek ND The inability to lose weight from diet and exercise alone can be extremely frustrating. There are many factors that affect weight management, and for those who struggle with this it may be worth investigating other causes of this “stubborn metabolism.” One such cause is the functioning of the thyroid gland and its respective hormones. Thyroid hormones play crucial roles in how the body uses energy and regulates appetite. Additionally, fat cells, also called adipose tissue, contains their own messengers and hormones that affect energy stores and usage. The interaction between these cells, their messengers and

By: Dr. Robyn Murphy, ND The verdict is in, your genes are not your destiny. Advances in genetics and epigenetics have evolved through observations that environmental factors influence genetic expression to directly impact an individual’s health. Epigenetic changes are reversible while effects of genetic variations are modifiable. 1,2 Today, in the midst of personalized medicine, understanding an individual’s genetic blueprint provides simple yet powerful strategies to significantly make a difference in one’s health. While science reveals how general lifestyle strategies in diet, exercise and stress reduction significantly impacts epigenetic modifications and thus gene expression and risk for disease; it is

Notre destin est-il inscrit dans nos gènes? Cette question commune est une préoccupation majeure pour la plupart, en particulier pour ceux qui envisagent des tests génétiques, se demandant si l’on veut vraiment le savoir ou non, de peur de découvrir que notre sort est scellé (rien ne peut être fait). Eh bien, la réponse est simple: NON; vos gènes ne transportent pas votre destin. Bien que cela dépende de divers facteurs à l’instar de l’impact du gène, cet article a pour principal objectif d’examiner comment l’épigénétique et l’adoption de certains styles de vie peuvent influencer positivement la santé, et que

By: Dr. Robyn Murphy, ND Are your genes your destiny? This common question is top of mind for most, especially for those who are considering genetic testing. Questioning whether or not you really want to know, in fear that nothing can be done. Well, the simple answer is, NO, your genes are not your destiny. While this may be due to a number of factors, such as the impact of the gene, the main topic of this article is discussing how epigenetics and particular lifestyle strategies can positively influence health, and that knowing your genes may just be the missing

Polycystic ovarian syndrome (PCOS) is a health problem affecting one in ten women of childbearing age. PCOS is caused by an imbalance of reproductive hormones that creates problems in the ovaries. This imbalance can lead to infertility (in fact it is the most common cause of that condition), problems with the menstrual cycle and development of cysts in the ovaries. PCOS impacts women of childbearing years and can happen any time after puberty. It has been proven that PCOS can exist in women of any body type.  Since there is a genetic component, it’s a good idea to ask your

We’re all looking for ways to optimize our health, keeping us happy and moving. What we don’t want, however, is a fatty liver. Keeping our livers healthy and functioning properly is paramount, as this powerhouse organ, our body’s second-largest organ, is one that works 24 hours a day. Our livers are responsible for over 500 biological functions such as detoxification, energy storage and creation, and processing nutrients, processes all we put into our body, helps fight infections, cleanses our blood, and converts carbohydrates, proteins and fats into the energy we need on a daily basis. Speaking of fats, there are

The thyroid is the butterfly-shaped gland in our throat that is an essential regulator in our body. It produces thyroid hormone (TH), which affects virtually every one of our cells and is a contributor to metabolism and keeping us energetic and active. When it is producing TH in appropriate quantities, it holds many organs and systems in equilibrium. We know that there is close communication between the endocrine and immune systems and that alteration in levels of TH can affect the function of the immune system. Thyroid hormones also have a role in inflammation, autoimmunity and clearing pathogens from the

Most of us are aware that stress is one of the key drivers behind many of our modern health complaints. Stress is a risk factor for hormone imbalance, obesity, cardiovascular disease, and cancer as well as mental illnesses like anxiety or depression and even brain-related conditions such as Alzheimer’s. Ever wondered how stress can have such a devastating impact on our body? The mind-body connection, or the stress-illness connection for purposes of this article, works in different ways. It’s useful to remember firstly that the stress response is meant to improve your chances of surviving a physical threat to your

It’s Fall and everyone is “ramping up”. Whether you are a parent with a new school schedule to manage or an employee managing new projects at work, it seems that as the days get shorter, the To-Do lists get longer. Changes in schedule and workload can contribute to rising levels of stress. As a result, maybe you aren’t getting sufficient sleep, which can lead to even higher levels of the stress hormone cortisol. Both stress and insomnia can lead to a suppressed immune system, which can in turn lead to increased susceptibility to any colds and flu being passed around
