Europe’s fibre frenzy: excess intake can backfire
While most Europeans still miss the UK’s 30 g daily fibre target, recent trends have pushed some consumers to exceed 50–70 g per day. Such high intakes are linked to bloating, diarrhea, constipation and reduced mineral absorption, especially when fibre is increased rapidly without sufficient hydration.
The Recomposition Trap: Why Your Pursuit of the "Holy Grail" Is Keeping You Average
The article argues that pursuing simultaneous fat loss and muscle gain—often marketed as the "holy grail" of physique change—is a trap for most lifters. While body recomposition is possible in labs, real‑world results are slow unless you’re a beginner, an enhanced lifter, obese, or returning from injury. It also debunks popular fads like intermittent fasting, smart scales, and zero‑calorie BCAAs, emphasizing that total energy balance, consistent training, nutrition, sleep, and stress management drive progress.
