Does Intermittent Fasting Hurt Your Gains?
A 2026 RCT put time-restricted eating up against unrestricted eating during an actual bulking phase. The muscle and strength gains came out identical, but the real reason why isn't the one you'd guess.

Does Resistance Training Actually Make You Sharper?
Cardio gets all the attention in the exercise-and-brain conversation. Two current reviews looked at resistance training specifically, and found a real but domain-specific effect, not the uniform brain boost the headline version implies.

Does Caffeine Actually Make You Stronger?
A single dose of caffeine measurably improves bar speed and power in the gym, that part's well established. What's less talked about: most of that research is built on men, and the picture looks meaningfully less certain once you look at women specifically.

Can You Actually Train Your Muscles to Get Longer?
Sarcomerogenesis: the muscle-growth mechanism nobody talks about, where fibers add contractile units end to end instead of getting thicker. It's real, directly measured in humans, and researchers are currently arguing about exactly what triggers it.

Does Creatine Actually Help Your Brain?
Creatine's reputation is built on muscle, but there's a real, separate body of cognitive research behind it too, including one honest methodological catch most headlines skip past.

Creatine: What It Actually Does (And Doesn't)
The most researched supplement in sports nutrition, and still one of the most misunderstood. What creatine actually does for muscle and strength, backed by the real studies, no myths either direction.
