How accurate is Breezing?
As accurate as the gold-standard Douglas Bag method. For more details, here’s the Validation Study.
The word “metabolism” gets thrown around a lot. What is metabolism?
Your metabolism is a set of chemical processes powering your body to maintain life. Metabolism determines how your body uses energy. When we refer to a “fast” or “slow” metabolism, we’re actually referring to metabolic rate – the speed of your metabolism.
What is REE?
Your resting metabolic rate, or resting energy expenditure (REE), is the energy your body uses to sustain vital functions – breathing, cell growth and repair, circulation. If you spent the day lying down without moving, your body would still burn calories to carry out these basic functions. The number of calories you burn is your REE.
Why do I need to track my metabolism?
Your metabolism is the missing piece to weight management. Typically, your body burns most of your energy intake when you’re at rest – not when you’re exercising. Once you know how many calories your body actually uses, you can adjust your diet and exercise plan to reach your goals. In fact, the American Dietetic Association strongly recommends basing your energy needs on your resting metabolic rate.
Tracking your metabolism also allows you to better understand changes in your body. Having an extremely fast or an extremely slow metabolism may be a sign of a disorder. Knowing your metabolic history helps you know when to consult your healthcare specialist.
How does my metabolism affect my weight?
Conventional wisdom says: The higher your metabolism, the more you can eat without gaining weight. And vice versa.
Here’s how it works: When you eat, you take in calories. Your metabolism transforms these calories into your body’s fuel. What isn’t used is later stored as fat. Weight loss occurs when you take in fewer calories than what you use. Weight gain occurs when you take in more. And your weight stays the same when the calories you take in are equal to what you burn. The total number of calories you burn (your total energy expenditure) comes from your resting metabolism and your level of physical activity.
In today’s world, resting metabolism makes up as much as 70-85% of total energy expenditure. When you know your metabolism, you’ll know how many calories you’re really burning. Instead of following a “standard” 1500 or 2000 calorie meal plan, you’ll be able to fine-tune your diet to precisely match your daily calorie needs.
What is the weight loss plateau?
Here’s what usually happens:
As you lose weight, your metabolism drops. And as your metabolism drops, your body tries to stop losing weight.
For the same amount of exercise, you burn fewer calories than before. For the same diet, your slower metabolism keeps you from seeing results. You’ve reached the weight loss plateau – a point where you can’t lose any more weight with your diet and exercise routine.
To avoid the weight loss plateau, Breezing adjusts your diet and exercise plan every time your metabolism changes. This way, you stay on track.
I know my metabolism, and I am eating fewer calories and exercising more. Why is my weight the same?
Your weight can stay the same even when your overall body composition is changing.
Your weight comes from both fat tissue and lean tissue. Lean tissue – which includes organs, bone, and muscle – weighs more than fat tissue. If you lose fat tissue, but gain muscle tissue, this contributes to your weight. However, gaining more muscle tends to raise metabolism, which can benefit long-term weight management.
In addition to tracking your weight and metabolism, you can track body composition changes with an impedance scale (such as the Withings Body Analyzer) or by regularly measuring your waist-to-hip ratio.
Can’t I just estimate my metabolism?
Everyone’s metabolism is different. And even individual metabolism can change over time. Though ways to estimate your metabolism exist, they’re based on generic assumptions and don’t include the many “unknown” factors that make your metabolism unique to you. For that reason, metabolic estimates can be inaccurate.
What determines my metabolism?
- Body size – Those with larger frames tend to have higher metabolisms.
- Body composition – Individuals with greater muscle mass burn more calories, even at rest.
- Age – Growing older, metabolism slows down.
- Sex – Men typically have a faster metabolism than women of the same age and weight.
- Health and medical conditions – Stress, medications, pregnancy, and hormonal disorders (such as hypothyroidism) can change metabolism.
- Genes – Born this way.
How does Breezing measure my metabolism?
Breezing measures your metabolism using indirect calorimetry.Indirect calorimetry is the most accurate method of metabolic measurement available, the Gold Standard preferred by the American College of Sports Medicine, American Dietetic Association, World Health Organization, and other institutions. While traditional indirect calorimeters are bulky, difficult-to-use, and often only found in the doctor’s office, Breezing is different. Through sensor technology and creative engineering, Breezing streamlines indirect calorimetry – so it’s simple, mobile, and effective.
How do I prepare for my Breezing measurement?
To get the most accurate measurements, please be sure to follow the appropriate guidelines. These conditions are printed in the User Guide that comes inside the Breezing package. For an electronic copy, please email us at firstname.lastname@example.org
Can I share my results?
Yes. Breezing lets you share your results through Facebook, Twitter, and email. Email shows your results as both a screenshot and as a .csv file. You have direct control over who sees your progress – and how you want them to see it.
The Breezing App collects metabolic data, which may be stored on iCloud or Google Cloud, or on a user mobile device that has the Breezing ProTM/Breezing MedTM Mobile Application., see link below for detail.
