The famous 30% metabolism boost works out to about 24 calories, and two later labs could not reproduce it at all. What two randomised trials do support is duller and more useful: a glass before meals, for a couple of pounds over twelve weeks.
By volume, yes — that is chemistry. But in a 12-week trial people gained about 2.6 lb of lean mass while losing up to 7 lb of fat, so their weight went down, not flat. And the density constant everyone quotes was measured in rabbits and dogs.
The only randomised trial of a corset for weight control watched compliance fall from 100% to 10% in nine months — the authors said it 'could therefore not be evaluated.' There is no mechanism, and the one measured effect of abdominal compression is worse reflux.
Cold exposure does raise the calories you burn, and over weeks of daily cold air one study trimmed fat mass slightly. But the research used hours of cool air, not a three-minute plunge — and no study shows a cold plunge takes fat off.
If you’ve been training hard, eating well, and still watching belly fat cling to you, has someone told you the culprit is your cortisol rhythm? Here is what the research behind that idea can and cannot say. A 2017 meta-analysis…
You know the routine: hard session, decent dinner, a couple more messages under bright lights, one last episode. You sleep seven or eight hours and still wake up flat. The first heavy set bites, “easy pace” doesn’t feel easy, and…
A randomised trial in 120 older adults found aerobic exercise grew the hippocampus by 2% and improved memory — that part is real. The famous 'four times faster' figure comes from mouse cells in a dish, and the phrase does not appear anywhere in the paper it is credited to. It entered at the press release.
Twenty-four years of literature contains zero randomised trials of a commercial detox tea. The mechanism is a laxative — and even four to six litres of diarrhoea cuts calorie absorption by only about 12%. The liver damage, though, is documented.
The checklist this page always promised, finally on the page. It sorts your answers into what the ECSS/ACSM consensus says must be excluded first — energy intake, iron, thyroid, infection, mood — and refuses to give you a score, because that consensus found no marker good enough to be generally accepted.
The pinch test everyone repeats has no clinical basis and runs backwards to what a skinfold measures. What biopsies after major weight loss actually found, and the correction we owed this page.
