Fitness & physical performance

Train with your hormones, not against them. We cover strength, hypertrophy, VO2 max, recovery, and injury prevention through an endocrine lens. Discover how training, nutrition, and daily activity can impact testosterone levels and support natural balance. Use estradiol balance for joint health, plan sleep taper cycles before competitions, and turn smart physiology into new PRs.

In nondiabetic men, a CGM is most useful when diabetes risk is elevated and you use it to track repeatable trends (it reads glucose in interstitial fluid every few minutes), but it can mislead when you treat one-off post-meal “spikes” as verdicts because readings lag behind blood glucose and responses can vary even to the ...

For muscle growth, a fast-food meal can “count” if it delivers roughly 20–40 g of complete, leucine-rich protein to trigger muscle protein synthesis (MPS) without dragging in excessive refined carbs and added fats that crush the protein-to-energy ratio. This guide shows how to order “surgically” — prioritizing grilled meats and simple sides while skipping the ...

When weekly calories (and protein) are matched, calorie cycling (“metabolic confusion”) tends to produce fat loss similar to a steady daily deficit, but higher-calorie days may improve adherence and help manage diet fatigue tied to adaptive thermogenesis (a drop in resting metabolic rate during prolonged dieting). Here’s how to structure high- and low-calorie days so ...

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 ...

Masturbation does not permanently lower baseline testosterone because the hypothalamus‑pituitary‑gonadal (HPG) axis maintains homeostatic hormone production, and clinical studies show no statistically significant change in systemic testosterone after orgasm. The real story is short‑term fluctuation—like the often‑misread ~145% spike on day 7 of abstinence—and what that means (and doesn’t) for muscle, mood, and long‑term health. ...
