Body composition, which is the relative proportion of muscle to body fat, rules health.
Metabolic syndrome and type 2 diabetes, are closely linked to body composition.

526 apparently healthy adults were grouped in tertiles (equal thirds) of muscle/fat ratio (MFR), from highest to lowest.
Those with lowest MFR had 5.4 times the odds of metabolic syndrome.

Metabolic syndrome and insulin resistance are linked, and vary with ethnicity, but this variation is almost if not entirely due to variation in muscle/fat ratio. pubmed.ncbi.nlm.nih.gov/19820012/
Aging and insulin resistance are also linked, but this has almost nothing to do with aging per se, but to percent body fat. pubmed.ncbi.nlm.nih.gov/1400882/
There's no difference in insulin sensitivity between young and old when matched for being athletes, normal weight, or obese.
Age has nothing to do with it: body composition and fitness rule.

Skeletal muscle insulin resistance is the primary defect in type 2 diabetes. ncbi.nlm.nih.gov/pmc/articles/P…
Obese people have greater whole-body insulin resistance, but this is due to low ratio of muscle to body fat. academic.oup.com/jcem/article/8…
Low cardiorespiratory fitness is linked to impaired insulin sensitivity and "was the most prevalent abnormality in a population at risk for IRS and T2DM but without overt disease."
You know what to do: get fit.

A single bout of high-intensity, glycogen-depleting exercise improves insulin sensitivity. diabetes.diabetesjournals.org/content/36/4/4…
Resistance training is more effective than endurance training for improving insulin sensitivity and body composition.
Resistance training is just much harder and produces a higher level of metabolic stress. ncbi.nlm.nih.gov/pmc/articles/P…

Resistance training can increase muscle mass and decrease visceral fat, and therefore massively decrease your risk of metabolic syndrome, T2D, and chronic disease.
And of course, a diet of real whole foods, low in refined carbs.

More muscle mass and less body fat are keys to health.
Health authorities often focus on the body fat, but pay less attention to muscle.
Lift weights and eat real (not ultra-processed) food.
