Evidence-based. Direct.
Without trends.

Which six values count, why ferritin cannot be judged without CRP, and why a mildly raised TSH usually does not explain your fatigue.

Too little energy alongside a high training load shuts down hormones, bone and immune function. Warning signs, risk groups and the way back.

The drug regulates appetite, not body composition. What is proven, what happens after stopping, and why strength training decides the outcome.

The most common causes are not in the blood count. What belongs in the basic panel, why sleep apnoea gets missed, and the four fallacies the guideline names itself.

Committed parents are not the problem, missing load management is. Growth and load, energy deficiency, supplements and sleep, with warning signs and six ground rules.

Longevity means healthspan, not lifespan. What the studies support, what merely sounds good, and where to start. The pillar article on the topic.

The body does not respond to training hours, but to a stimulus it can process. Four stages, nine adaptations and four markers that are enough to steer by.

Most answers are calendar dates. Your body follows capacity instead: four criteria, a four-stage build-up, and what the evidence says about surgery.

Strength, power, grip and conditioning in a single movement. What the BELL trial shows, what a swing does to your back, and where the limits are.

Strength disappears three times faster than muscle mass. What really changes about dosage, protein and recovery, and what testosterone contributes.

Sitting time isn't the problem, staying still is. What postural shifts, active breaks and a height-adjustable desk actually deliver.

Curl-up, side bridge, bird dog. Plenty know the exercises, almost everyone gets the dosage wrong. Plus the honest evidence and the limits of the method.

After 40 your body doesn't build muscle worse — it just forgives fewer mistakes. What really counts: load, joints, recovery over harder training.

Deep sleep is the phase where your body repairs itself. You can't force it, but you can stop sabotaging it. What counts and what is a myth.

A ring, a watch or a mat measures your sleep every night. The question isn't whether the number impresses — it's whether it's true, and what it does to you.

Same time every night, wide awake, thoughts on a loop. Why your stress hormone wakes you, when that's a real problem — and what you can do about it.

Recovery isn't the gap between your workouts. It's the part where progress happens. Which levers really work — sleep, nutrition, heat, HRV — and which ones are overrated.

Creatine is supposed to sharpen your thinking too. The meta-analyses find a small effect, the EU authority finds none. Both are true — and for most people the muscles are the better reason.

Some people sacrifice everything for a long life. And forget what they wanted to live for. Where optimisation tips over into maximisation — and why the ratio decides, not the protocol.

Citrate, oxide, glycinate or malate? The form decides, not the milligram number on the label. Which magnesium form your body actually absorbs and when the pill is unnecessary.

Tired but wired. If you wake at three and can't come down, you rarely have a sleep problem — you have a cortisol problem. Why your system won't switch off at night — and what actually helps.

"Within normal range" doesn't mean optimal. What a complete blood count measures, what it misses — and which values genuinely matter for high performers.

80% of people experience back pain at least once. Most try exercises — and notice after two weeks that nothing has changed. Here's why.

Relieving acute back pain quickly is possible — if you know what really happens in the first 48 hours. And if you stop doing what feels right but actually makes things worse.

Why more training doesn't automatically make you better — and what happens when you ignore the biological law of progression.

Sleep duration and sleep quality are two different things. Failing to separate them means you can lie in bed for nine hours — and still feel like you only got four.

Between miracle cure and warning, the truth usually lies in the dose. Which supplements are genuinely a risk, which are overrated — and why "natural" doesn't mean "harmless".
