Metabolic Assessment

Have you ever wondered why you're exercising to lose weight but aren't
successful? Are you trying to build endurance with limited results? The
answer lies in your metabolism--not whether it's fast, slow, good or bad but
in how understanding your own, UNIQUE metabolism will help you achieve
your goal of better health, fitness, or athletic performance. In
fact, knowing how your metabolism works is essential to creating a plan to
live healthy, look better, and perform to your full potential.

Body By X offers metabolic assessments that include individualized fitness programs based on your
resting and exercise metabolic rates and fitness goals. It's not one exercise
program fits all!

Your metabolic assessment will:

  • Tell you WHEN and HOW to burn calories MOST efficiently
  • Help you establish training zones so you can achieve YOUR specific goals without overtraining
  • Determine the EXACT amounts of carbohydrates and fat your body is metabolizing at various exertion levels

Our metabolic testing provides the MOST effective tools for weight loss by telling you where your heart rate should be when you exercise.

Body By X uses state-of-the-art technology, including a proven software solution that make it easy to access your assessment results and customized fitness program online.

Who Benefits From Metabolic Tests?

  • People who want to lose weight
  • Athletes looking to train with purpose and gain a competitive advantage
  • Routine exercisers who feel stuck in a routine
  • Anyone who wants to exercise SMARTER not HARDER!

Resting Metabolic Rate Test (RMR)

Your Resting Metabolic Rate (RMR) is the minimum number of calories
your body needs to support its basic physiological functions, including
breathing, circulating blood and all of the numerous biochemical reactions
required to keep you alive. Your RMR is generally 60-80% of your total
daily caloric expenditure.

Knowing the minimum number of calories your body needs is important if
you're trying to lose, gain or maintain your current weight.

Resting Metabolic Rate is the amount of calories you would burn if you
continued to sit in a chair all day, doing nothing at all.

  • Things That Affect Your Metabolic Rate:
  • Muscle - More muscle increases your RMR.
  • Age - Your RMR can decrease (if inactive) with age.
  • Genetics - Can be a factor to your RMR
  • Meals - Small regular meals will increase your RMR.
  • Pregnancy - It can increase your RMR.
  • Crash Dieting - It will decrease your RMR.
  • Medications - Certain medications with increase or decrease your RMR

Exercise Metabolic Rate Test (EMR)

Just as everyone’s metabolism is unique, so is everyone’s response to
exercise. The EMR test reveals your body’s unique response to physical
activity at different levels of intensity. By measuring the volume of oxygen
your body takes in and utilizes (VO2), the volume of carbon dioxide exhaled
(VCO2) and your heart rate we can determine how many calories you burn
per minute while exercising and how many of those calories are drawn from
fat versus carbohydrates and MOST importantly, how aerobically efficient
you are at different levels of exercise intensity.

I'm 45 and for most of my life I have been struggling with my weight.  I have always exercised but was never really confident enough to take it beyond easy to moderate; even though I really wanted too.  I have tried many diets and eating programs thinking that all I needed was to find the right food combinations that worked for my body and then my body will become the right size.  Since there is a never ending supply of eating and exercise programs, I have been busy trying new things, but never finding something that I could stick too, until now.  New Leaf is a program that combines pure science with your own personal needs and goals and gives you a workout and calorie plan.  There are no false promises or magic solutions, just fact based reality that if you are ready to work, will work for you.    I have never worked so hard, or felt so good on any program before.  The best for me is that this is a program that I believe in and will use forever.  No more wasting time on false advertising.  With this program I am confident that I can reach any fitness goal that I want to, as well as learn how to eat right for me.
