<\/span><\/h3>\n\n\n\nIndividually, high fat and low muscle each increase diabetes risk. Together, they create a compounding effect that researchers have termed “metabolic obesity” or, in more severe cases, “sarcopenic obesity” a condition where an individual appears metabolically compromised despite having a normal or even low body weight.<\/p>\n\n\n\n
The fat-to-muscle ratio (FMR) integrates both markers into a single index. A 2022 study in the Journal of Clinical Endocrinology & Metabolism found the FMR to be a stronger predictor of insulin resistance than either metric alone, outperforming BMI and waist circumference.<\/p>\n\n\n\n
InBody measures: <\/strong>Both SMM and Body Fat Mass are printed on every result sheet, allowing immediate calculation of the fat-to-muscle ratio by any clinician or health professional.<\/p>\n\n\n\n<\/span>Secret 5: Trunk Fat Mass Central Adiposity Beyond Waist Measurement<\/span><\/h3>\n\n\n\nWhile waist circumference is a common proxy for central adiposity, it cannot distinguish between subcutaneous abdominal fat and visceral fat. InBody’s segmental analysis provides trunk fat mass as a more precise measure of the lipotoxic fat depot most closely associated with hepatic insulin resistance and ectopic fat deposition in the liver and pancreas.<\/p>\n\n\n\n
Research published in Diabetologia (2019) demonstrated that trunk fat mass was more strongly correlated with fasting insulin and HOMA-IR (a validated insulin resistance score) than both total body fat and waist circumference.<\/p>\n\n\n\n
InBody measures: <\/strong>Segmental body fat analysis separating trunk fat from arm and leg fat. Available on InBody 570 and above models.<\/p>\n\n\n\n<\/span>Secret 6: Leg Muscle Mass The Forgotten Metabolic Engine<\/span><\/h3>\n\n\n\nThe muscles of the lower limbs, quadriceps, hamstrings, gluteals, and calves represent the largest single muscle mass in the body and are therefore the dominant site of glucose disposal. Selectively low leg muscle mass (often caused by sedentary behaviour, ageing, or poor nutrition) disproportionately impairs whole-body glucose metabolism.<\/p>\n\n\n\n
A large-scale Korean cohort study (n = 15,000+) published in Medicine (2021) found that low leg muscle mass was associated with a 50% increased risk of new-onset diabetes over a 10-year follow-up period, independent of age, BMI, and abdominal obesity.<\/p>\n\n\n\n
InBody measures: <\/strong>Segmental lean analysis for each limb right leg, left leg, right arm, left arm, and trunk. Identifies regional muscle deficits that total body measurements would miss.<\/p>\n\n\n\n
