Truly blessed for both of your responses. My diet is pretty tight due to food allergies: no dairy, gluten, yeast products, peaches, pears, cocoa, coconut, oranges, broccoli, etc. I eat mostly proteins and healthy fats along with a few carbs (brown rice, sweet potatoes, veggies, etc).
Diet
I understand you avoidance of certain foods based on your food allergies.
However, "I eat mostly...healthy fat..." is a vague term. With many individual it is mean a dramatic restriction of saturated fat. Hopefully, that isn't part of your eating plan.
Saturated Fats are a vital component to hormonal production.
My Diet
Due to a metabolic condition that I have, I am on a Ketogenic/Intermittent Fasting Diet.
Approximately, 70% of my calories come from fats. The percentage of fats recommended on a Ketogenic Diet (Drs Stephen Phinney and Jeff Volek) is approximately: 55% Monounsaturated, 27% Saturated, and 18% Polyunsaturated.
My Saturated Fat intake is around 40%. My Lipid Panel is excellent.
Rather than rambling on, I'll stop there.
On another note, I'm looking to continue my profession as a physical education teacher for elementary students but also want to become a trainer. Any suggestions if I should go for my Certified Strength and Conditioning Specialist or Certified Personal Trainer?
Certified Strength and Conditioning Specialist, CSCS
I obtained my CSCS in 1998.
I've host the Albuquerque Strength and Conditioning Clinic since 2012; a non-profit event sanctioned with the National Strength and Conditioning Association and the National Academy of Sport Medicine. Information about the clinic is listed here:

I did some part time Personal Training for two years.
For the last twenty years, I have worked in Speciality Fitness Equipment Sales (Selling upper end fitness equipment.)
First, I worked in Retail Sales, now I work in Outside Commercial Fitness Equipment Sales (Schools, Colleges, Physical Therapy, Motels, Apartments, Police, Fire, etc).
My Recommendation
1) Purchase The Textbook:
Essentials of Strength Training and Conditioning
Read it cover to cover. Then read it again cover to cover and take notes. Read the book a third time, focus on your notes.
2) Practice Exam: Purchase the Practice Exam.
a) Take the test: On questions you answered incorrectly, look up the answers an assess why you answered it incorrectly.
b) Repeatedly Take The Test: Keep taking the test until you get all the answers right.
c) In reading the exam questions, break the question down into two parts.
Read the first part and assess if that statement is correct.
Read the second part of the question and assess if the statement is correct.
The Reason:
The exam questions are often composed of two statement tied together. One part of the question is correct, the other part is incorrect.
Another thing they do is interchange terms.
Personal Example:
I continually incorrectly answered the "Sliding Filiment Theory" question, even after repeated reviewing the Textbook.
What they did is interchange some of the terminology. I knew the right answer but for some reason didn't pick it up.
Analogy of Paying Attention to Detail
A friend of mine once told me, "Elvis Presley and I both went to different schools at the same time."
My reply was, "You knew Elvis?!!" For some reason, I missed the part "went to different schools".
c) Continue to re-read the Textbook and Take The Test.
Learning = Brainwashing
As you know, learning something is a repetitive process. You keep doing something until it is ingrained in your head.
My Son
The summer after my son was in pre-school, each day we'd break down the alphabet and go over it until I was ready to throw up.
When he started back in First Grade that fall, he had an edge because I had brainwashed the alphabet into his head and he'd learned to reading.
Kenny Croxdale
Man; I can relate to that!
