Recent studies show that the so-called “fat-burning zone” displayed on commercial fitness machines frequently does not align with an individual’s best heart rate for losing fat. Utilizing clinical exercise tests could deliver more accurate guidance to tailor weight loss objectives.
New insights emphasize the limitations of commercial exercise devices, stressing the necessity for a more individualized exercise regimen.
A team from the Icahn School of Medicine at Mount Sinai found that the ideal heart rate for burning fat is not the same for everyone, and it often conflicts with the “fat burning zone” shown on numerous commercial exercise machines.
The researchers propose that clinical exercise tests, assessing an individual’s physical response to exercise, might be a more effective way to assist people in meeting their fat loss targets. Using a machine learning approach, these conclusions were published in the journal Nutrition, Metabolism and Cardiovascular Disease.
“The commonly recommended ‘fat-burning zone’ provided by most commercial exercise machines, depending on factors like age, sex, and heart rate, has not been verified, leading to potential misalignment with personalized weight loss goals,” says lead researcher Hannah Kittrell, MS, RD, CDN, who is also a Ph.D. candidate at Icahn Mount Sinai in the Augmented Intelligence in Medicine and Science lab.
Kittrell also directs the Mount Sinai Physiolab, focusing on clinical body composition and exercise physiology at Mount Sinai Morningside.
The investigation revealed individual differences in fat-burning rates during exercise, illustrating the necessity for customized exercise plans. FatMAX, a term used to describe the peak fat-burning rate during aerobic workouts, is particularly relevant for those looking to maximize fat loss.
The study contrasted heart rate at FATmax, as gauged during a clinical exercise test, with the predicted heart rate in the general “fat-burning zone.” Among 26 participants, the researchers observed a significant discrepancy, with an average difference of 23 beats per minute, indicating that general “fat-burning zone” recommendations might be imprecise.
Future research will focus on whether personalized exercise prescriptions result in greater weight and fat loss, along with improvements in health markers that pinpoint risks like type 2 diabetes, obesity, and heart disease.
Dr. Girish Nadkarni, the study’s senior author, says, “We wish to motivate more people and fitness trainers to apply clinical exercise tests to devise exercise routines designed for fat loss. It accentuates the potential of data-driven methods in refining exercise.”

Frequently Asked Questions (FAQs) about fokus keyword: fat-burning zone
What does the recent research from the Icahn School of Medicine at Mount Sinai reveal about commercial exercise machines?
Answer text in full: The research reveals that the “fat-burning zone” commonly displayed on commercial exercise machines often does not correspond to an individual’s optimal heart rate for fat loss. The study emphasizes that general recommendations may not provide accurate guidance, and individual variations in fat burning underscore the need for personalized exercise plans. Clinical exercise testing, which assesses a person’s response to physical activity, is suggested as a more precise way to align exercise intensity with personalized weight loss goals.
How was the research conducted and what were the key findings?
Answer text in full: The researchers compared heart rate at FATmax, measured during a clinical exercise test, to predicted heart rate within the typically recommended “fat-burning zone.” Among 26 individuals, they found a mean difference of 23 beats per minute between the measured and predicted heart rate, indicating poor agreement. These findings were published in the Nutrition, Metabolism and Cardiovascular Diseases journal, and they used a machine learning model to reach these conclusions.
Why is personalized exercise planning important, according to the study?
Answer text in full: Personalized exercise planning is important because the study uncovered individual variations in fat burning during exercise. The “fat-burning zone” recommended by commercial exercise machines has not been validated, so individuals may be exercising at intensities not aligned with their personalized weight loss goals. Personalized exercise routines, based on clinical exercise testing, are suggested to help people more effectively reach their fat loss objectives.
What are the implications of this study for individuals seeking to lose fat?
Answer text in full: The study implies that relying solely on commercial exercise machines’ “fat-burning zone” recommendations may lead to suboptimal results in fat loss. Individuals seeking to lose fat might benefit from clinical exercise testing, which can provide more accurate guidance in tailoring exercise intensity to their unique physiological response. This more personalized approach could help them achieve their weight and fat loss goals more effectively.

Who knew? I’ve been trusting my exercise machine’s readouts for years. Might be time to look into some professional guidance or clinical testing.
so this means my treadmill at home might be misleading me? that’s concerning! I thought i was in my fat burn zone all this time.
This article was really helpful, it shows the importance of personal trainers, and how tech can sometimes mislead. We shoud all focus on what’s best for our unique bodies!
This study is eye-opning. Ive been relying on those machines for my fat loss goals. Time to reconsider my strategy I guess. Thanks for sharing this.
This is a really important research. people should be aware of the fact that machines don’t know our body as we do. we need more personalized planning in exercise.
