Why It Is So Difficult to Stick to Resolutions

For some reason I always find March to be the most difficult time of year when it comes to sticking to my New Year's resolutions. Whatever the reason for this mental hurdle, I am determined to overcome it this year.  My main goal is to form healthy habits. I am not interested in sacrificing things because eventually I will feel deprived and fall back into making unhealthy choices. Humans are biologically predisposed to routine. As such, the best way to improve what we eat, what we crave, how often we eat, and when and how frequently we exercise is by making the desirable choices habitual. Years of ritual cannot be altered over night. According to a study performed by the University College of London, published by the European Journal of Social Psychology, it takes on average 66 days to make an action habitual. However, the deviation from that average is extremely high, ranging between 18 and 254 days.
It takes less time to implement habits that function in keeping us alive. For example drinking a glass of water with each meal. It is more difficult to make a habit of exercising for 20 minutes a day because we are biologically wired to do so only in attempt to acquire food or escape from danger. It is also partially due to our biological predispositions that we struggle to establish habits like healthy eating. In a time where hunting and gathering were the only options, food was hard to come by. We are programmed to desire sweet and fatty foods because they provided the most bang for the buck. These inclinations have largely contributed to our existence as a species therefore they continue to guide our behaviors. Relying on evolution is futile because nature's habits take even longer to alter. But now we no longer need to consume excessive amounts of sugars and fats at a single meal to nourish our bodies and prepare for a time where we may not have access to food. Rather, we need to consume these types of foods because our minds are convinced there will be a time where we need that energy. 
Let's also point out that after years of eating processed sweets and fats the veggies and fruits just do not taste as good, initially. I can tell you from past and recent experience that if you cut the processed foods out of your diet and then reintroduce them, they simply do not compare to the wholesome, nutrient-dense, natural foods. So why do  we struggle to stick to a natural and wholesome diet? That is the age old issue, and fascination, of mind over matter. In today's world Americans, along with most citizens from developed nations, are dying primarily from lifestyle diseases.  Four of the top ten leading causes of death (heart disease, cancers, strokes, diabetes mellitus) are due to lifestyle choices that we consciously make. As a multifaceted discipline, nutrition focuses on studying food, nutrients, other chemical substances, the above's relation to health and disease, the process of ingestion through excretion and the social/economical,/cultural/psychological implications of food and eating. We used to eat to survive but now we eat for enjoyment. The two do not have to be considered independent of one another. 

March is National Nutrition Month and I challenge you to savor your food, enjoy eating with friends and family, and lastly be grateful that you have food for sustenance.

A Look into the Science

One diet does not fit all! Has anyone else ever been fixated on that 2000 calorie number? Growing up I remember my mom emphasizing that magical number. But is it really magical? Research says NO!! (see my "A Little Bit of Research" section below to search for articles on this topic) How then did 2000 calories become the standard recommendation and why does it continue to reign? This number fails to accurately take into account important aspects such as height, weight and activity level, however, what it does do is provide a decent estimate to start with.




Counting calories is an important aspect of finding and maintaining your health but it is not the only aspect! What exactly are calories and why should we keep track of them? 

CALORIES or Should I say KILOCALORIES

  • First of all when you see "calories" on a label it is really referring to kilocalories- for some reason the government has refused to correct this common error so just be aware that Calories = Kilocalories
  • Kilocalories are a measurement of heat energy needed to raise the temperature of 1000 grams of water 1 degree Celsius.
  • We are constantly using and consuming kilocalories. This relationship is called energy balance
    • To maintain a weight we must find an energy equilibrium(caloric intake =caloric output)
      • Positive Energy Balance is when intake exceeds output-->weight gain
      • Negative Energy Balance is when output exceeds intake-->weight loss
  • Calculate your BMR and Resting Metabolic Rate (RMR):
  • The RMR is an estimation of the kilocalories you expend when you are not fasting but completely relaxed- this is typically 6% higher than your Basal Metabolic Rate (calculation of your basic energy requirements when fasting). 
    • BMR for Woman= ((weight)/(2.2lb/kg))/(.9kcal/1hr)*24hrs/1Day
      • the average number of calories burned per hour in a woman is .9kcal/kg
      • Take me for example:
        • ((126)/2.2ln/kg))/(.9kcal)*(24hr)= 1,527.3 kcal BMR
        • (1,527.3*.06) + (1,527.3)= 1,618.9 kcal RMR
        • the average number of calories burned per hour in a man is 1.0kcal/kg
    • The BMR and RMR are rough estimates to provide you with a starting point only. Various factors can increase or decrease the actual amount!!!!
      • Exercise, Age, Muscle Mass, Body Surface Area and Gender are just a few!
        • Physical Activity can increase your energy expenditure as much as 25-40% 
  • Energy Expenditure
    • Indirect Calorimetry:
      • EER: Estimated Energy Requirements that are based on the Food and Nutrition Board (as seen in chart above)
        • take into account:
          • Weight
          • Height
          • Gender
          • Age
          • Physical Activity Level
        • See Energy Expenditures from MyPyramid to calculate your estimated expenditure!! (mypyramid.gov)
      • This is probably your best estimate as to how many kilocalories you should be consuming within a couple hundred kcals.


Breaking Down your Kilocalorie Consumption into the Food Groups

  • Daily Values
      • Standards for energy producing nutrients
        • Major energy producing nutrients are 
          • Fats 20-30%
          • Carbohydrates 45-65%
          • Proteins 10-35%
            • note that you may decide what percentage you choose as long as it equals 100%
        • Recommended Range of Kilocalorie allotment

  • Translating the Recommended Values to Tangible Numbers:
    • EXAMPLE: Expected Energy Expenditure= appx 2400kcal
      • Of these 2400 kilocalories
        • Fats= (2400* .25)=600kcal/day
        • Carbohydrates=(2400*.45)=1080 kcal/day
        • Proteins=(2400*.30)=720 kcal/day
****These are the very basics of science in nutrition. Much more goes into finding and maintaining a healthy weight!

An Introduction and Explanation

For the sake of starting this blog off on the right foot, there are a few things I want to discuss. 

1. Because I am currently a student I have access to both updated and outdated textbooks and health literature. Unlike history, English and Mathematics are constantly changing sciences! I will endeavor to post the most up to date information in terms of nutrition. Alas, I am fallible so I apologize up front if something I post is not quite accurate. If you notice an error please let me know I will correct it as soon as possible.

2. With so many nutrition perspectives, it will be difficult for me to touch on them all. I can promise, however, to answer general dietetic questions and offer my perspective on most inquiries.

3. Remember that I am not yet a registered dietitian so please take what I say with a grain of salt.

4. I hope this blog will help people find the motivation and tools to start or to continue their own healthy lifestyle. Only you know what your body really needs, but you must first learn to listen to it. 

5. I will most likely post a lot about the Paleo Lifestyle. Please note that this may not necessarily be the best, nor is it the only reputable diet out there. It is simply the diet I have chosen to experiment with at this time in my life. I am no expert on it; I have only been dabbling in it for about a year. Dabbling being the operative word as I have yet to become a true primal eater. Why then, some of you may ask, do I feel as though I can write about it? That is a wonderful question that I do not quite have the answer for. Perhaps it is that nagging desire we get when we stumble upon a "new discovery" that compels me to document my journey with the Paleo Lifestyle. Or maybe it is a mental fortification of sorts; failure is much harder to swallow when you publicize it. So there are two possibilities: a.) Succeed, in which case I can give myself a pat on the back. b.)  Fail in front of everyone. --What a motivator our egos are.

6. Most importantly, I look to inspire all of you to make a promise to yourselves that you are going to take care of your bodies. 

As a basic physiological need, nutrition precedes all others in terms of importance. Our bodies must be fed before we can even worry about safety, social relationships and emotional health. Feeding our bodies alone is not the only step to fulfilling our worldly potential, but it does lay the foundation.

 Like all things in life balance is crucial. The balance in my life does not equal balance in your life. Balance is dynamic - ever changing - and we have to work relentlessly to find and maintain it. 

  “Health is a state of complete harmony of the body, mind and spirit. When one is free from physical disabilities and mental distractions, the gates of the soul open.”  ~B.K.S. Iyengar
