Keep Track of Your Body’s Most Important Biomarkers for Fat Loss

Spren empowers you with the data that truly drive positive changes in fitness and performance.

Biomarker/Insight

Description

Body Fat (%)

Fat mass / total mass; the proportion of your body that is made up of fat.

Fat Mass

Total weight of your fat mass (lbs/kgs)

Lean Mass

Total weight of your body from non-fat sources like muscle, organs, water, connective tissue, etc. (lbs/kgs)

Android Fat

Body fat around the trunk and upper body; an increase in android fat is associated with an impaired glucose tolerance and insulin resistance (higher risk of type 2 diabetes) (lbs/kgs)

Gynoid Fat

Body fat that forms around the hips, breasts, and thighs; often referred to as “reproductive fat”. The ratio of this to android fat is also related to risk of type 2 diabetes and cardiovascular disease (lbs/kgs)

Resting Metabolic Rate

Minimum daily calorie requirements needed to sustain your basic life-sustaining functions.
