Can you chew gum while fasting? What it means for ketosis and autophagy

Can you chew gum while fasting? What it means for ketosis and autophagy

Sugar-free gum is usually compatible with a ketosis-focused fast because one piece is typically a negligible caloric input (often kept under ~30 calories total during the fasting window), but any calorie- or sugar-containing gum can blunt a stricter fast aimed at autophagy, where the safest approach is staying truly calorie-free. The key is how many ...

Sea moss does not have solid clinical evidence showing it directly boosts testosterone or male fertility, but its high iodine content can support thyroid hormone production (T4/T3), which indirectly affects energy and libido when a deficiency is present. Here’s what the data actually supports—and where the “fertility superfood” marketing goes beyond the science. “Sea moss ...

Does alcohol cause inflammation? What men need to know about the immune response

Does alcohol cause inflammation? What men need to know about the immune response

Alcohol causes systemic, dose-dependent inflammation by producing acetaldehyde and activating liver immune cells (Kupffer cells) to release pro-inflammatory cytokines such as TNF-α and IL-6, while also weakening the gut barrier so bacterial toxins can enter the bloodstream. That immune “alarm” can keep firing long after the buzz fades—affecting blood vessels, testosterone production, and sexual function. ...

Biohacking is a data-driven approach to improving physiology by measuring key biomarkers (such as glucose, cortisol, and testosterone), changing lifestyle or environmental inputs, and re-testing using a “measure, modify, measure” loop. Here’s how mechanisms like epigenetic regulation and hormesis can help counter modern stressors and extend healthspan. “Biohacking is often marketed as a shortcut, but ...

Peptides vs TRT: Which therapy optimizes male performance and longevity?

Peptides vs TRT: Which therapy optimizes male performance and longevity?

TRT best optimizes male performance when a man has clinically low testosterone (levels decline about 1% per year after age 30) because it replaces missing androgen directly, while growth-hormone secretagogue peptides target recovery and tissue repair by stimulating the pituitary to pulse more of its own HGH—so neither is universally “better” for longevity. Here’s how ...
