| Body Fat % | BF % = tina_fit | The percentage of your body that is fat. One of the top predictors of long-term health, lifespan, metabolism and athletic performance. Improve your body fat percentage by losing fat, building muscle or both. | 23.7 | % |
| Lean Mass % | LM % = 100 - BF % | Your non-fat or muscle percentage (also including water, bone, etc.). | 76.3 | % |
| Fat Mass | Fat Mass (lbs) = user weight (lbs) x BFM | Decreasing fat mass is associated with improved health, lifespan and athletic performance. However, it is not as strong of an indicator as body fat % because body fat % incorporates both fat and lean mass. | 39.6 | lbs |
| Lean Mass | Lean Mass (lbs) = user weight (lbs) x (100% - BFM) | Your non-fat or muscle mass (also including water, bone, etc.). More lean mass is associated with better health, lifespan, metabolism and athletic performance. | 127.4 | lbs |
| Basal Metabolic Rate | basalMetabolicRate, https://journals.physiology.org/doi/full/10.1152/ajpendo.2000.279.3.E539 | Metabolism is the sum of all chemical processes that take place in your body. It is also the amount of energy (Calories) your body needs daily. |
Track your daily caloric intake and eat under this number to lose weight or over to gain. In general, a higher metabolism means better health and faster weight-loss. Improve yours by building muscle and/or improving cardiovascular fitness (VO2 max).” | 2000 | Kcal (Cal) | | Weight | weightAsKg | Weight as inputted by the user. | 167 | kg | | Waist-To-Hip % | Waist-To-Hip = (waist circumference) / (hip circumference) | The waist-to-hip ratio (WHR) is a measure used to assess fat distribution around your waist, hips, and buttocks and assess if it’s putting your health at risk.
