5 Surprising Facts About Body Fat
Body fat is more than just a number on the scale. Let's explore five fascinating points:
1.Location Matters
Visceral fat around organs tends to pose a higher health risk than subcutaneous fat beneath the skin.
2.Metabolism Influence
Having more lean muscle increases basal metabolic rate, helping burn more calories at rest.
3.Age Adjustments
Body fat distribution often shifts with age, which can change how health professionals interpret the data.
4.Health Over Aesthetics
A moderate body fat level can promote hormone balance and protect organs. Extreme leanness might not always be healthier.
5.Multiple Measurement Methods
Techniques like skinfold calipers, bioelectrical impedance, and DEXA scans can cross-verify your calculations.
