- Physically active overweight and obese people were more likely to have high cholesterol, high blood pressure, and diabetes — dispelling "fat but fit" claims.

fitness expert told Insider weight and BMI are not the only indicators ofhealth .
A new, large study made headlines this week for finding that overweight and obese people have significant health issues, even if they are fit and exercise regularly.
But one fitness expert told Insider the study ignores that there is more than one measure of health - including mental health - and the findings could deter people who are making good progress, fitness-wise.
The researchers behind the study, published in the European Journal of Preventive Cardiology, sought to dispel claims that it's possible to be healthy and overweight - otherwise known as "fat but fit."

"Our findings refute the notion that a physically active lifestyle can completely negate the deleterious effects of overweight and
However, Noam Tamir, the founder and CEO of TS Fitness who trains people of all sizes, says the widespread attention on this study perpetuates an idea that being overweight is a losing battle.
Overweight people in the study had health isues even if they worked out regularly
In this study, the researchers analyzed data from 527,662 people in Spain. They were grouped based on weight, such as normal, overweight, or obese, and on activity levels varying from regularly active, moderately active, and inactive.
The researchers found that, compared to normal-weight people, overweight and obese people were twice as likely to have high cholesterol, four times more likely to have diabetes, and five times more likely to have high blood pressure regardless of their activity levels.
"Exercise does not seem to compensate for the negative effects of excess weight," said Lucia.
This finding builds on existing research that the risk of developing heart issues increases with weight gain. In another large study of nearly 300,000 people, researchers found that your chances having a stroke, heart attack, or high blood pressure increases as your waistline expands.
A fitness expert says there's more to health than weight and BMI
In a society where being thin and fit is praised, respected, and idealized, Tamir says shining a spotlight on these kinds of studies, without broader context, can discourage overweight people who work out.
"It definitely diminishes their accomplishments," Tamir told Insider.
Tamir also said measuring body mass index (BMI)-which the study authors used to assess participants' health - is not a perfect metric because it doesn't capture body composition, such as muscle or fat mass.
Stress reduction, improvement in agility, and better mental health are important exercise benefits that should be considered in assessing health, according to Tamir.
These are the types of benefits Tamir stresses to his clients who are looking to get into shape. If anything, weight-loss comes secondary.
"I tell my clients losing weight is an extra, added bonus of exercise," he said.
Tamir gives credit to overweight people who choose to move compared to those who put off exercising. In his mind, if you're moving your body, "you're already ahead of the curve."
