Thirty Japanese adults, sixteen weeks, and cognitive scores that rose and then fell again a month after the tablets stopped. An independent panel says nobody has repeated it.
The confident objection is that your gut destroys it. A six-month trial in 54 people says body stores rose by a third. The unanswered question is whether that does anything for you.
A panel convened because nobody could agree what zone 2 was. They agreed on a definition — and then wrote that the adaptations might not be unique to it. Meanwhile the calculators cannot find it on you.
An electrical engineering department with no stake in earthing built the instrumentation and measured the current flowing between a grounded body and the earth. Billionths of an amp, tracking nothing but movement.
One study links this plant to testosterone and it was done in male albino rats. Four years later the same three authors, at the same doses, reported enzymes leaking out of liver and kidney cells.
Eight men in a sealed metabolic chamber showed the mechanism plainly: alcohol speeds your metabolism up and stops your fat-burning cold. Then thirty-one population studies failed to find the weight gain.
Everyone trained the same arm the same way for twelve weeks, with their other arm as the control. Biceps size changed by anywhere from minus two percent to plus fifty-nine. That spread is the answer.

Cut 500 a day and the rule says 52 lb in a year. The measured response to a change in intake has a half-time of about a year, because your expenditure falls as you shrink. Same arithmetic, completely different trajectory.
572 studies and 486,538 cancer cases say yes, with a clear dose-response. The protective effect of moderate drinking disappeared once studies stopped counting sick quitters as non-drinkers.
