Exercise
Strength training is now recognized as essential for human health, and is a mandatory requirement in WHO guidelines. Beyond physical longevity, lifting weights triggers neurological growth and stabilizes emotions for sharper cognitive performance.

Brain scans of 10,125 adults link exercise to larger brains
In MRI scans of 10,125 adults, people who exercised on more days had larger gray matter, white matter, and hippocampus volumes. The links were small, the study took one snapshot, and it did not test memory or weight training.

Any strength training is tied to a 23% lower risk of early death
In 80,306 adults in England and Scotland, any strength training was linked to a 23% lower risk of early death. In US adults over 50, low muscle strength went with about twice the odds of dying.
Optimizations
You lift more in the evening, but morning training builds as much
Muscles are a little stronger in the evening, but reviews of trials find that morning and evening lifting build similar strength and muscle. Training at a steady hour matters more, and late morning has no proven edge.

Scientists are testing a new injectable drug, CBL-514, that makes unwanted fat cells in a chosen body area self-destruct. Early…
videoDr Réginald Allouche blames an overloaded liver for weight gain
Dr Réginald Allouche argues that an overloaded liver drives weight gain. European guidelines confirm the link in the other direction: losing 5% to 10% of body weight clears liver fat and can reverse liver damage.
videoRests over a minute grow a bit more muscle by allowing more work
A 2024 review of 9 trials found slightly more muscle growth with rests longer than 60 seconds between sets. A 2022 trial shows why: short rests grew as much muscle once extra sets matched the total work.
