Is BRI better than BMI? The new longevity metric men need to know
Dr. Susan Carter, MD: Endocrinologist & Longevity Expert
Jan 15, 2026 · 12 min read
The Body Roundness Index (BRI)—a 1–16 score calculated from height and waist circumference—has outperformed BMI in large studies at predicting all-cause mortality because it captures abdominal “roundness” tied to visceral fat. If BMI has mislabeled your physique or missed hidden belly-fat risk, BRI shows what your shape says about your metabolic health and longevity. “We ...
Healthy carbonated drinks: The science behind the switch for men
Dr. Susan Carter, MD: Endocrinologist & Longevity Expert
Jan 13, 2026 · 9 min read
Switching from sugar-sweetened soda to low- or no-sugar functional carbonated drinks removes the liquid fructose hit that drives insulin resistance and visceral belly fat (which can suppress testosterone) and can add prebiotic fibers like inulin that feed beneficial gut bacteria such as Bifidobacteria. “Healthy” on the can isn’t a guarantee—here’s how the key ingredients actually ...
Mediterranean diet snacks to optimize testosterone and heart health in men
Dr. Susan Carter, MD: Endocrinologist & Longevity Expert
Jan 07, 2026 · 9 min read
Mediterranean-style snacks built around monounsaturated fats, polyphenols, and protein (such as walnuts, olives, and plain Greek yogurt) can support testosterone and heart health in men by preventing sharp post-snack glucose/insulin spikes and lowering chronic inflammation that suppresses testosterone production and damages endothelial function. Here’s how to use between-meal “fuel” to keep energy steady while protecting ...
The anabolic crunch: Are protein chips a viable tool for male metabolic health?
Dr. Bruno Rodriguez, DPT, CSCS: Strength, Recovery, and Physical Therapy Expert
Dec 13, 2025 · 10 min read
Protein chips can be a viable tool for male metabolic health when used as an occasional swap for traditional chips, because their higher protein and lower rapidly digesting carb load tends to increase satiety and better supports muscle repair than starch-heavy snacks. The trade-off is that most are ultra-processed and often high in sodium and ...
How body fat speeds up aging in men: The science of metabolism and longevity
Dr. Susan Carter, MD: Endocrinologist & Longevity Expert
Dec 10, 2025 · 14 min read
In men, excess visceral (deep belly) fat speeds up aging by acting as an inflammatory endocrine organ that releases cytokines such as TNF-α and IL-6, driving chronic inflammation, insulin resistance, and faster atherosclerosis. Losing just 5–10% of body weight in midlife can measurably improve blood sugar, blood pressure, and inflammatory markers—making fat loss one of ...
