as much as five times more protective than muscle gain.
“Muscle gain only seemed beneficial when it happened in adolescence, between 13 and 18 years old,” Bell says. “This is a busy time of growth and maturity and might be when we should promote some muscle gain as well. [Heart] benefits seem to fade after then.”
His bottom-line message: While muscle is important for outcomes like mobility and independence, fat control seems to be a higher priority when it comes to keeping markers for heart disease in check.
Bell stresses that the findings are critical because the seeds of future heart trouble are sown among youths and adolescents, who are otherwise healthy.
While “serious events like heart attacks don’t tend to happen until older ages, heart disease doesn’t happen overnight,” Bell notes.

What should you focus on?
Lona Sandon is an associate professor in the school of health professions at UT Southwestern Medical Center in Dallas and reviewed the study findings.
She says you should aim to prevent excess fat gain from the start, rather than focus on fat loss later.
“Instill healthy eating and activity habits early on to maintain a healthy body weight throughout childhood and adolescence for the best chance of reducing early onset of heart disease risk factors,” Sandon says. “And by early on, I mean in the womb and infancy.”
There should be a focus on educating parents about healthy pregnancies and healthy feeding patterns. “Start with breastfeeding and feeding healthy whole foods and age-appropriate portions during infancy and early childhood,” Sandon advises.
Restricting calories during childhood is generally not a good idea, as this is a time of growth, Sandon cautions. “Calories and quality foods are needed for proper growth and development.”
Instead, exercise and sports can be a great way to keep a growing body trim. “Active play goes a long way toward keeping kids fit without putting the focus on body fat,” Sandon stresses. “Also active kids may be more likely to carry over those active habits into adulthood.”
The key to reducing heart disease is eliminating fat, getting people active and eating healthy will greatly reduce the risk of fat in the first place. If you need help with what you should be eating or which exercises are best for eliminating fat, contact a doctor, nutritionist or trainer.
