Plain-language reviews of GLP-1 research, practical guides, and evidence-based tips for getting the most out of your medication journey — from the team behind GLTrax.
Medicare's GLP-1 Bridge gives eligible Part D members Wegovy, Zepbound, or Foundayo for a flat $50 a month. Here's who qualifies, how to actually get it, and the four mistakes sending people home empty-handed.
Three randomized trials put an eating window head to head with ordinary calorie restriction. The weight came off about the same either way. Here's what that means if you're on a GLP-1.
You took the quiz and got your era. Here's what the Researcher, Newbie, Plateau Warrior, and Maintenance Pro each say about where you are on the journey, and how to handle what comes next.
PJ's latest reel asks the question out loud, so here's the honest answer. What the randomized trials actually show about GLP-1-type medications and obstructive sleep apnea, what's FDA-approved today, and what's still emerging.
You saw PJ's Costco Cart reel fly by — here's the full breakdown. The ten items, protein versus calories for each, and why every one earns its spot when you're eating with a GLP-1-sized appetite.
It is the question almost everyone on a GLP-1 quietly searches at 2am: can I ever stop? Two randomized withdrawal trials, SURMOUNT-4 and STEP 1, have a clear and uncomfortable answer about what happens to the weight when the medication goes away.
For years, "food noise" was a word patients used and no test could see. At EASD 2026, a brain-imaging study of an investigational GLP-1 drug showed food-cue responses changing in the scanner — matching what people have reported all along.
In one semaglutide trial, 12% of people still hadn't lost 5% four weeks after reaching the full dose. Most of them got there anyway — here's the data.
Average weight loss from the main trials for tirzepatide, semaglutide and orforglipron — the dose ramp for each, and when the weight actually comes off.
A Gila monster survives on a handful of meals a year. To manage it, it evolved a version of a human gut hormone that lasts hours instead of minutes — and that molecule became the first GLP-1 medication.
These medications don't flood your brain — they reach a few specific places that sit outside its security barrier. Understanding which ones explains both why appetite quiets down and why nausea is the signature side effect.
For years, people on GLP-1 medications reported wanting alcohol less — without trying to. Researchers have now tested it properly, and the finding is narrower and more interesting than the headlines suggest.
The hormone behind semaglutide was found in 1987 and was almost useless as a medicine — it disappeared from the blood in about two minutes. The fix came from a lizard in the Arizona desert.
Menstrual changes are one of the most-discussed GLP-1 side effects online — and one of the least documented. Here's what a 410,000-post analysis found, plus the contraception warning many people never hear.
Fatigue is the second most-reported GLP-1 side effect, and feeling cold barely appears in the official documentation at all. Here's what's usually behind both — and the handful of things worth actually checking.
In analyses of GLP-1 communities, the psychological and social side of weight loss is the second-biggest thing people talk about — and almost nobody prepares you for it. Here's what actually changes, and what to watch.
GLP-1 drugs like semaglutide drive real weight loss — but some of it is lean muscle. Here's what the evidence says, and how to protect muscle while you lose fat.
Just starting semaglutide or tirzepatide? Here's a plain-language guide to your first month on GLP-1 — what to expect, how to handle side effects, and what to track.
