Red and near‑infrared light therapy (photobiomodulation) may lead to small, body‑contouring reductions in waist, hip, or thigh measurements—typically measured in centimeters—by stimulating mitochondrial energy production and influencing how fat cells release stored fat, but it has not been shown to produce large or consistent drops in body weight or BMI. Here’s what the research really ...

Energy drinks without sucralose aren’t automatically healthier—their health impact is driven mainly by caffeine dose and total sugar, and most healthy adults should keep caffeine under about 400 mg per day from all sources. Here’s how to decode what’s used instead (like sugar or stevia) and read labels for gut, hormone, sleep, and long-term metabolic ...

A 100‑gram protein meal after resistance training can support muscle protein synthesis for longer rather than being “wasted,” because the body slows gastric emptying and releases amino acids into the bloodstream for roughly 12 hours (vs. a quicker rise-and-fall with 25 grams). That finding challenges the old 30‑grams‑per‑meal rule and reframes how to time bigger, ...

Algae cooking oil is a reasonable upgrade if it replaces butter, coconut oil, or shortening, because its mostly unsaturated, high‑oleic fat profile can lower LDL cholesterol similar to other high‑oleic vegetable oils, and it tolerates high heat with a smoke point around 535°F. Here’s how it actually stacks up against common seed oils in cooking ...

In observational studies, male cigarette smokers average about 15% higher total testosterone and 13% higher free testosterone than non-smokers, likely because nicotine alters liver hormone metabolism and slows testosterone breakdown. That “smoker’s paradox” can still coincide with erectile dysfunction and infertility as smoking damages blood vessels and testosterone-producing Leydig cells, so higher lab numbers don’t ...
