Switching from sugar-sweetened soda to low- or no-sugar functional carbonated drinks can reduce added-sugar intake and is associated with lower risk of calorie surplus, adiposity, and insulin resistance. Some options also add prebiotic fibers like inulin that may support beneficial gut bacteria such as Bifidobacteria. “Healthy” on the can is not a guarantee. Here is ...

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 reducing sharp post-snack glucose and insulin spikes and lowering chronic inflammation that can suppress testosterone production and damage endothelial function. Here’s how to use between-meal “fuel” to keep energy ...

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 to 10% of body weight in midlife can measurably improve blood sugar, blood pressure, and inflammatory markers. This makes ...
