The dimensions has by no means been a good friend to Mana Mostatabi. Even again in highschool, when she ran a fast 100m on the varsity observe workforce, her BMI – a ratio of weight to top – put her within the chubby class.
“My dad at all times joked that I ought to be a wrestler,” Mostatabi says because of her construct. Many skilled athletes flunk BMI exams. Some are thought-about overweight regardless of their health, and lots of docs say it isn’t a useful metric to deal with.
“BMI is a really crude measure,” says Dr. Richard Joseph, a doctor at Brigham and Girls’s Hospital who makes a speciality of metabolic well being. “It doesn’t inform me a lot about your underlying well being,” he says. Folks is usually a regular weight however have low muscle mass and excessive physique fats, whereas others have greater physique weight however are muscular and lean.
That’s why Mostatabi has discovered a brand new instrument – a physique composition scan – that measures her physique fats and muscle mass, that are two key metrics of well being. “It’s very affirming,” Mostatabi says. Over the past yr, she has misplaced ten kilos of physique fats and in addition gained a number of kilos of muscle. “This truly provides me info,” to trace progress. “It truly is motivating,” she says.
Physique composition scans have gotten an more and more standard approach to gauge well being and there are many totally different varieties.
An MRI (magnetic resonance imaging) is taken into account the gold customary, but it surely’s not sensible for most individuals given the expense and entry to medical imaging.
Dr. Joseph orders DEXA – dual-energy X-ray absorptiometry – scans for a few of his sufferers. These scans measure bone mineral density, and in addition measure physique composition and fats distribution. They sometimes value greater than $100, however costs have begun to drop in some areas as demand rises and extra machines can be found.
An choice that’s taken off in gyms and exercise studios, reminiscent of Anytime Health and Orangetheory Health is bioelectric impedance evaluation, utilizing units such because the InBody or the Evolt 360. Relying on the studio, the scans are sometimes free with membership or can be found for a small price. This take a look at isn’t as exact as an MRI or DEXA, however is dependable at monitoring adjustments over time, so long as individuals comply with instructions.
Mana Mostatabi makes use of a physique composition take a look at to trace her health. It is helped her decrease her physique fats and enhance muscle.

Mostatabi had her first InBody scan in January, when she signed up for a power problem at Orangetheory. “It’s a brilliant easy course of,” Mostatabi says, which takes lower than a minute.
The gadget seems to be like a scale with two arms. “You step onto the machine,” which has a steel base, she explains and also you maintain onto the ends of the 2 arms which ship a protected, low-level electrical present by the physique, estimating fats and lean mass.
“How briskly that present is returning to the electrodes provides a measurement of how a lot fats mass and muscle you may have, as a result of the present travels by these physique tissues at totally different speeds,” explains Scott Brown, Vice President of health at Orangetheory. The expertise is many years previous, and has turn into more and more standard with the arrival of business units and rising demand.
Mostatabi says you may’t really feel something in the course of the take a look at, and the outcomes are despatched on to a wise telephone app. Her first scan gave her a benchmark to enhance upon.
She explains her health took a nosedive in the course of the pandemic, and he or she was aiming for a recent begin this yr. All winter she pushed herself by 60 minute courses that mixed resistance coaching, weight lifting, cardio on a treadmill and rowing. “I used to be very diligent,” averaging about 5 to 6 courses per week.
“The InBody scan is the primary instrument I’ve ever used that exhibits good points,” she says. Mostatabi was accustomed to weighing herself, and recollects the frustration when the dimensions wouldn’t budge. Now, even when she hasn’t misplaced weight, she is aware of her physique is more healthy, with a decrease share of physique fats and a rise in muscle.
“It’s simply extremely empowering,” she says, realizing that girls who weight practice and construct power can count on to dwell longer and more healthy lives.
On common, ladies acquire much less muscle at a slower charge in comparison with males. Throughout Orangetheory’s eight week ‘transformation problem’ the corporate discovered that males who have been centered on muscle good points added about .83 lbs of muscle over eight weeks, on common, in comparison with a half pound of muscle acquire for females. Although throughout all members there was solely about .1 lb of common muscle acquire.
Eight weeks isn’t quite a lot of time to realize muscle, explains Brown. And he says it’s necessary to set “real looking objectives and targets” given the variability from individual to individual. The flexibility to construct new muscle is influenced by gender, age and genetics.
Dr. Joseph says the rationale it may be useful to know your muscle mass is as a result of research present that power is a predictor of longevity. Additionally, lack of muscle will increase the danger of falling, which is a prime reason for loss of life from harm amongst older individuals. “Lots of people are under-muscled,” Joseph says.
On the subject of physique fats, having an excessive amount of can enhance the danger of metabolic illness, particularly visceral fats, which surrounds the belly organs together with the abdomen, liver and intestines. “It’s inflammatory,” Joseph says and drives up the danger of coronary heart illness. The American Faculty of Sport Drugs units health classes for physique fats primarily based on age and gender, however there isn’t not an agreed upon goal for what’s thought-about superb. Utilizing the ACSM requirements, most Individuals may very well be categorised within the “poor health” class, because the common physique fats amongst adults within the U.S. is 33%. The U.S. navy considers the optimum physique fats for navy health to be between 10% and 20% for younger males and as much as 25% for middle-aged males. Girls sometimes have extra physique fats, with a great vary from 15% to 30% for younger ladies and as much as 38% for middle-aged ladies.
Joseph says the rule of thumb for health is that “it’s you versus you.” Reasonably than fixate on an exterior benchmark, “it’s most necessary to take a look at traits over time,” in your physique composition, he says.
It’s potential to lose fats and acquire muscle, with out shedding any weight. That is what occurred to Karen White, who’s 59, and a licensed well being coach in Alexandria, Virginia. She’s gained about three kilos of muscle over the past three years, and has shed physique fats,too. Her physique fats has dropped from 26% right down to 22%. “Actually, I’m the very same weight,” after three years of monitoring, however the constructive adjustments in her physique composition are profound.

“The misperception is that older individuals cannot acquire muscle, and that is completely not true,” she says. She factors to a brand new shopper she’s working with in her 60s. Already, after a number of months, her shopper has misplaced physique fats and elevated her power.
White agrees that it’s necessary to set real looking expectations, and acknowledge the adjustments in physique composition could take time. She has gained a few pound of muscle per yr, on common, and feels quite a bit stronger.
Provided that muscle peaks in our 30s, it’s necessary to do strength-training to keep up muscle mass, particularly as we age. “The chance of frailty actually will increase exponentially with age,” Dr. Joseph says and muscle-loss, additionally known as sarcopenia, impacts an estimated 45% of older adults, particularly ladies. Weight coaching can assist fend off this loss.
