Data & App Access

Even Tim Ferriss Measures

Tim Ferriss has long emphasized the power of DEXA scans to understand body composition beyond the scale. At Prefusion Health, we use the same gold standard measurement to guide smarter training, nutrition, and optimization; built on real data, not assumptions.

What You Get, Every Time

Measure First

Interpret Correctly

Execute With Support

Track Progress

Refine Over Time

Low muscle mass lowers metabolic output, making it harder to burn calories, maintain strength, and sustain long-term results.

Muscle Loss

We target the root causes that hold you back

When insulin isn’t working efficiently, your body favors fat storage and resists fat loss even with proper diet and exercise.

Insulin Resistance

Persistent inflammation interferes with recovery, energy levels, and how your body responds to nutrition and training.

Chronic Inflammation

Chronic stress drives visceral fat accumulation, disrupting metabolism and increasing health risk beyond what scale weight shows.

Elevated Visceral Fat

Imbalanced hormones can slow fat loss, impair recovery, and reduce motivation even when effort and consistency are high.

Hormonal Imbalance

Declining bone density often signals deeper age-related changes that impact strength, stability, and long-term resilience.

Age-Related Bone Loss
