An evidence summary with two things the creatine literature never mentions: loading moves the scale by kilograms of water, and creatine nudges a creatinine reading that a clinician may be watching.

Food and identity on a GLP-1: three empty plates in purple, teal and orange seen from above

When Food Was Your Whole Social Life

Some people arrive on a GLP-1 having been the host, the baker, the one who knew every restaurant. When appetite goes quiet, the role built on top of it can go quiet too, and that loss is real even when the weight loss is wanted.

Mounjaro vs Zepbound: two identical rounded shapes side by side, one teal and one purple

Mounjaro vs Zepbound: Same Molecule, Different Labels

Same molecule, same manufacturer, same weekly ladder, two different sets of approved uses. What each tirzepatide label covers, what is identical underneath both, and why almost none of it changes the tracking.

The GLP-1 boxed warning: a teal butterfly shape inside a soft orange paper frame

The Boxed Warning on Your GLP-1 Label, Explained

The page you want at 11 pm after finding the words thyroid C-cell tumors on a leaflet. What the box actually says, why the human question is open, who the contraindication excludes, and the four symptoms the label lists.

GLP-1s and your eyes: a flat purple eye outline with a teal iris and an orange pupil

GLP-1s and Your Eyes: Where the Regulators Disagree

European regulators list a rare eye condition as a very rare side effect of semaglutide. The US labels do not mention it at all. Both positions are defensible, and the arithmetic behind the numbers is the part worth learning.

GLP-1s and Mood: What the Regulators Concluded

Reports of suicidal thoughts in 2023 triggered formal reviews on both continents. Both are finished. What each one examined, what changed on the labels, and the line a population finding cannot cross.

Eating too little on a GLP-1: a large purple plate holding only two small items

Eating Too Little on a GLP-1: Why It Happens and What to Watch

A medicine that turns appetite down works exactly as intended, and the same effect makes it easy to drift into eating far too little for months without noticing. What tends to show first, and why appetite cannot be the signal any more.

What GLP-1s are approved to treat: a purple capsule ringed by four colored circles

What GLP-1s Are Actually Approved to Treat

Every approved indication across eleven GLP-1 products in one table, read off the current labels. Which product carries the liver indication, which carries sleep apnea, which carries kidney, and what off-label actually means.

Wegovy tablets: a row of seven small round orange tablets with teal score lines

Wegovy Tablets: What Changes When Semaglutide Is a Pill

Semaglutide for weight management now comes as a daily tablet as well as a weekly injection, on the same label, with a different ladder and one fewer indication. The empty-stomach rules, the four-step climb, and what a daily cadence changes.

GLP-1 dose steps: an orange ball resting on the second of five rising purple steps

Do I Have to Keep Increasing My Dose?

The printed ladder looks like an itinerary everyone is expected to finish. Read the label language and almost every step up is conditional, several maintenance doses are ranges, and the route back down is printed too.

Time of day on a GLP-1: an orange sun and a purple crescent moon with a teal dot between them

Does the Time of Day You Inject Matter?

For the weekly injections the labels say any time of day, with or without meals. The day matters, the hour does not. The exceptions are the oral products, and they do not agree with each other.

GLP-1 pen needles: a slim purple pen shape on the left and a separate teal piece on the right

Do GLP-1 Pens Need Separate Needles?

Some pens arrive with the needle built in and hidden. Some need a fresh screw-on needle every single time. One ships its needles in the carton. The answer depends entirely on which device you were handed.

Telling people about a GLP-1: two empty speech bubbles in teal and orange overlapping

Do I Have to Tell People I Am on a GLP-1?

A prescription is a private medical fact, and who hears about it belongs to the person holding it. The few disclosures that genuinely are owed are clinical, not social.

GLP-1s and breastfeeding: an orange feeding bottle with a teal collar beside a purple droplet

GLP-1s and Breastfeeding: What the Labels Say

The lactation sections divide into three groups, and the grouping is surprising: the tablets restrict nursing for a reason that has nothing to do with semaglutide, and one pair of injections carries real human milk measurements while the rest carry none.

Byetta and the short-acting GLP-1s: two small orange circles side by side on cream

Byetta and the Short-Acting GLP-1s

The oldest medicine in the class behaves nothing like a weekly injection. Exenatide clears in hours, which explains the twice-daily cadence, the meal anchoring, and why there is no reservoir to miss a dose out of.

GLP-1s and SGLT2 Inhibitors: Two Different Jobs

Jardiance and Farxiga treat the same disease from an entirely different direction: they send glucose out in the urine. Different organ, different indications, different warnings, and often prescribed alongside a GLP-1 on purpose.

GLP-1s and blood pressure: a blank purple gauge dial with a single teal pointer

GLP-1s and Blood Pressure: What the Trials Measured

Blood pressure falls on these medicines by a modest, measured amount that the labels print in their trial tables. Heart rate goes up at the same time. Both numbers sit in the same tables, and neither is a reading about you.

Resting heart rate on a GLP-1: an orange heart beside a teal zigzag pulse line

Why Your Resting Heart Rate May Be Higher

A wearable shows a resting heart rate a few beats higher than it used to be. The labels address this directly, with numbers, a distribution that also shows up on placebo, and one sentence admitting the clinical relevance is uncertain.

Diabetic retinopathy and GLP-1s: a teal circle with an orange centre and lines radiating out

Diabetic Retinopathy and GLP-1s: What the Label Warns About

This is the eye warning that IS on the US labels, and the risk in the trial concentrated almost entirely in people who already had diabetic retinopathy. The mechanism the label names is rapid glucose improvement, not the drug.

Foods that sit badly on a GLP-1: three plain circles in purple, orange and teal in a row

Foods That Commonly Sit Badly on a GLP-1

No label names a trigger food, and this article says so. What the labels do establish is slowed gastric emptying, and the patterns people report all follow from it. The useful skill is testing one food at a time, not cutting out six groups.

Injection site reactions: an orange spot ringed in teal on a pale purple patch of skin

Lumps, Itching and Injection-Site Reactions

The rates differ sharply across the class, from 0.2 percent on Ozempic to 6 to 8 percent on Zepbound. And both tirzepatide labels report something unexpected: whether your body made antibodies to the drug predicts these reactions by about tenfold.

Setting a goal weight on a GLP-1: a target of purple, orange and teal concentric rings

How to Set a Realistic Goal Weight on a GLP-1

A trial average is the centre of a wide spread, computed on the people who stayed, measured at an endpoint that took well over a year to reach. All three facts change what it is fair to do with the number.

Kidney stones on a GLP-1: four smooth teal and purple pebble shapes on cream

Kidney Stones on a GLP-1: What One Label Reports

Gallstones are on every label in the class. Kidney stones are on exactly one. The Wegovy label reports urolithiasis at 1.2 percent against 0.8 percent on placebo, and the other labels say nothing at all.

Plant protein on a GLP-1: a purple bowl holding orange bean shapes

Hitting Protein Goals Without Meat

On a GLP-1 the constraint is volume, so the number that matters is protein per 100 grams of food. Tempeh and firm tofu carry roughly twice what lentils, chickpeas or black beans do for the same weight on the plate.

Late-night eating on a GLP-1: a purple crescent moon above an empty teal plate

Late-Night Eating on a GLP-1

Evening lands on a stomach that is still emptying from earlier, and the appetite that shows up at ten at night is usually not hunger in the simple sense. No cut-off times here, and no moralising.

Prediabetes and GLP-1s: a teal line with a small orange circle and a larger blue one

GLP-1s and Adolescents: What the Labels Allow

Two clean rules fall out of the labels: on the diabetes side the pediatric floor is 10, on the weight side it is 12. And the brand matters more than the molecule, because tirzepatide is established in children only as Mounjaro and semaglutide only as Wegovy.
