Summer is over, schedules are back to normal, and the days are getting shorter. For many of us, fall feels like a second January. It is a natural time to restart your routines.
But where do you start?
If you have ever picked a calorie goal from an online calculator and hoped for the best, there is a better way. Metabolic testing in Calgary gives you real numbers from your own body. At Eatuitive Nutrition, we test first, so your fall plan is built on facts instead of hunches.
Why Metabolic Testing in Calgary Beats Guessing
Online calculators use math formulas. They take your age, height, weight, and sex, then estimate how many calories you burn. But formulas describe an average person, and you are not one. Research shows these estimates can miss by a few hundred calories a day for some people. Eat too little and you may feel tired, hungry, and stuck. Eat too much and progress stalls.
Testing replaces the estimate with a measurement. Two tests matter most.
Resting metabolic rate (RMR) is how many calories your body burns just to stay alive. Think breathing, pumping blood, and staying warm while you lie still. For the test, you rest quietly and breathe into a mouthpiece for about 10 to 15 minutes. The machine measures the oxygen you breathe in and the carbon dioxide you breathe out. The more oxygen you use, the more energy you burn. It is painless. With our upgraded test, the carbon dioxide reading also shows your metabolic efficiency: how much fat and how many carbs your body burns at rest.
Body composition shows what your weight is made of: fat, muscle, water, and sometimes bone. Your bathroom scale gives one number. A scan breaks it into parts. Two people can weigh the same and have very different mixes, so this helps us set goals that fit your body.
The Main Numbers and What They Mean
Healthy ranges depend on your age, sex, health history, and goals. Treat these notes as general guides, and let your dietitian read your results in context.
1. Resting Metabolic Rate
We compare your measured number with what a formula predicted for you.
Lower than expected? Eating too little for a long time can teach your body to save energy. Low muscle, poor sleep, and age can also pull the number down. Sometimes a health issue, like a slow thyroid, is involved. What helps:
Eat at least as many calories as your RMR, and avoid crash diets
Lift weights or use resistance bands two to three times a week
Aim for seven to nine hours of sleep
Talk to your doctor if your number is far below expected
Higher than expected? More muscle burns more energy, even at rest. Hard training, stress, caffeine, or a recent illness can also raise it. This is often good news, because it means you can eat more than the formula said. If your result seems odd, we can retest when you are well rested. A high number with a racing heart or unplanned weight loss is worth a doctor visit.
2. Metabolic Efficiency (Fat vs. Carb Burn at Rest)
Your body runs on a mix of fat and carbohydrates. By comparing the carbon dioxide you breathe out with the oxygen you take in, our upgraded RMR test shows which fuel your body leans on while you rest. Most people at rest burn a healthy mix that includes plenty of fat.
Burning mostly carbs at rest? Sometimes it just means you had sugar or a carb-heavy meal before your test. It can also mean your body is not using fat for energy as well as it could. That pattern can be an early sign of insulin resistance, where your body has a harder time managing blood sugar. This test cannot diagnose insulin resistance, but it can flag when it is worth a closer look. What helps:
Follow your pre-test instructions so your result shows your true resting state
Cut back on sugary drinks and sweets, and build meals around protein, fibre, and whole-food carbs
Stay active most days, with both walking and strength training
Ask your doctor about bloodwork, such as fasting blood sugar or HbA1c
Burning mostly fat at rest? After an overnight fast, this is often a good sign that your body uses fat well for fuel. Very low-carb eating or long fasts can also push the number this way, so we read it alongside your usual eating habits.
Metabolic efficiency adds another layer to your RMR results, and it helps your dietitian fine-tune your carb and fat targets. Ask us about adding it when you book.
3. Body Fat Percentage
This is the share of your weight that is fat. Some fat is healthy. It protects your organs and helps your hormones work.
Higher than your target range? Over time, eating more energy than you burn is the most common reason. Low activity, poor sleep, high stress, some medications, and hormone shifts can all add to it. What helps:
Make a small calorie cut, about 10 to 20 percent below what you burn
Walk daily and lift weights to protect your muscle while fat comes down
Go slow, since steady changes are easier to keep
Lower than your target range? This usually means not eating enough, very heavy training, or both. Very low body fat can affect energy, mood, bones, and hormones. Eat more, ease your training load, and check in with your health care team.
4. Muscle Mass
Muscle helps you move, keeps your metabolism up, and supports your bones and balance.
Lower than expected? Common reasons are too little protein, little strength training, poor sleep, aging, and past crash diets. What helps:
Aim for 25 to 30 grams of protein at each meal
Strength train two to three times a week and add a little more challenge over time
High? That is usually a win. It can even explain why your scale weight looks “high” when you are lean. We help you eat enough to keep it.
5. Visceral Fat
This is fat stored deep in your belly, around your organs. Some scans estimate it. If it is high, the usual causes are extra calories, long hours sitting, stress, poor sleep, alcohol, age, and genes. What helps:
Get about 150 minutes of brisk walking or similar activity each week
Eat about 25 to 35 grams of fibre a day from beans, oats, fruit, and veggies
Cut back on alcohol and protect your sleep
Ask your doctor about bloodwork
Many scans also guess your body water. Day-to-day swings are normal, and dry Alberta air can make you need more fluids than you think. Ongoing swelling in your legs or ankles is worth a doctor visit.
A Simple Framework: Calories, Carbs, Fat, and Protein
Once you know your RMR, you can build your plan. Every food gives you energy, measured in calories. The three big nutrients carry different amounts per gram:
Protein: 4 calories per gram
Carbohydrate: 4 calories per gram
Fat: 9 calories per gram
Fat has more than twice the calories per gram, which is why small amounts of oil or nuts add up fast.
What about alcohol? Alcohol is not a nutrient, but it still has about 7 calories per gram. That is almost as much as fat, with none of the vitamins, minerals, or protein your body needs. Drinks can add up quickly, so count them when you plan your week.
Here is a sample. Say your RMR is 1,500 calories and you are moderately active. Multiply by about 1.4 to cover your daily movement, and you burn roughly 2,100 calories a day. For gentle fat loss, we might aim about 15 percent lower, near 1,800 calories. For a 70 kg (155 lb) person, that could look like this:
Protein: about 110 g (1.6 g per kg of body weight), or 440 calories
Fat: about 55 g, around 28 percent of calories, or 495 calories
Carbs: about 215 g, the rest, or 860 calories
What does that look like on a plate?
Protein: 100 g (3.5 oz) of cooked chicken breast has about 30 g. One large egg has about 6 g. Cooked lentils offer about 18 g per cup.
Fat: One tablespoon of olive oil has 14 g. Half an avocado has about 15 g.
Carbs: One cup of cooked rice has about 45 g. A medium banana has about 27 g.
These numbers are an example, not your prescription. Your own results, goals, and health history change them. Your dietitian will set targets that fit you, and we retest every three to six months to see what has changed.
