Compounded semaglutide and Telegram sellers: the real riskMedically reviewed

Grey-market GLP-1 is not a cheaper version of the same thing. Here is what HSA has found in seized weight-loss products, and what the law says.

GLP-1 dose titration: how the step-up schedule worksMedically reviewed

The dose climbs in fixed steps over months. The schedules are identical across the US, EU and Singapore — the tolerability wording is not.

GLP-1 medication in Singapore: what is legal and licensedMedically reviewed

GLP-1 medicines are Prescription Only in Singapore. Here is which products are registered, what the law says, and how licensed treatment works.

How GLP-1 medications work: appetite and your brainMedically reviewed

GLP-1 medications mimic a gut hormone signalling fullness and slowing gastric emptying. The brain mechanism, food noise, and Singapore prescribing rules.

Telemedicine is licensed under the Healthcare Services Act. Here are the instruments that govern it, what each one requires, and what they say about GLP-1.

Semaglutide vs tirzepatide: the head-to-head trialMedically reviewed

Semaglutide (Wegovy, Ozempic) against tirzepatide (Mounjaro, Zepbound) in the SURMOUNT-5 head-to-head, and what is registered in Singapore.

What is "food noise", and is it a real clinical thing?Medically reviewed

Patients described it before researchers named it. The first validated measures appeared in 2025. Here is what is established and what is not.

Body fat percentage vs BMI: which number to useMedically reviewed

Three numbers doing three different jobs. One of them has no authoritative healthy range at all, which is not what the internet will tell you.

Can you build muscle on a GLP-1 medication?Medically reviewed

Holding muscle on GLP-1 medication is well supported by the evidence. Building it is harder, slower, and depends mostly on whether you have trained before.

How much muscle do you lose on GLP-1 medication?Medically reviewed

One sub-study puts lean mass at a quarter of the weight lost on GLP-1 medication, a review of another nearer 40% — but placebo arms lost a similar share.

Is losing weight the same as losing fat?Medically reviewed

Body weight is fat plus lean tissue. What a DXA sub-study found about the split, and why the ratio decides whether a result holds.

Metabolic adaptation: why regain is almost the defaultMedically reviewed

After weight loss, energy expenditure falls by more than body-size change predicts. Here is what that means, what it does not, and what changes the odds.

The two phases of getting lean: the deficit, then afterMedically reviewed

Phase one takes the fat off. Phase two holds it, is longer, has no end date, and is where most results are lost. What each phase is for.

What "skinny fat" means, and how to avoid ending up thereMedically reviewed

"Skinny fat" means a normal body weight with a high body-fat percentage and low muscle. What the evidence shows, and why it is common in Singapore.

What a good week of 'getting lean' actually looks likeMedically reviewed

A concrete week: a protein target with the right denominator, two or three hard resistance sessions, walking, the injection day, and what to measure.

What a weight-loss programme measures, and what it missesMedically reviewed

Programmes are judged on kilograms because that is what the trials measured. What that metric cannot see, and what closing the gap would take.

What is lean mass, and why does losing it matter?Medically reviewed

Lean mass is everything that is not fat. Losing it lowers what your body burns at rest and costs you tissue that is slow to rebuild. Here is the evidence.

Why the scale is insufficient to track GLP-1 progressMedically reviewed

Body weight reports total mass, not what it is made of. What to track instead during treatment, and the evidence behind each alternative.

Beginner strength training when you have never liftedMedically reviewed

Most of what a beginner gains in the first month is nervous system, not muscle. Here is what to expect week by week, and how little training it takes.

Cardio-only exercise during weight loss: what it costs youMedically reviewed

In a trial of dieting older adults, aerobic-only exercise lost roughly double the lean mass of resistance training. Here is the evidence, and a myth.

Hitting your protein target when you have no appetiteMedically reviewed

Twelve tactics for reaching a daily protein target when food has stopped being appealing, sorted by sequencing, density and format.

How fast should you lose weight? What the evidence showsMedically reviewed

The severity of the deficit clearly changes what you lose. Whether speed matters independently is contested — two trials say yes, one says no.

How much protein do you need on a GLP-1 medication?Medically reviewed

Most guidance lands at 1.2–1.6 g of protein per kg body weight per day during active weight loss to preserve muscle — here's how to hit that in Singapore.

InBody, DEXA and smart scales: what each one measuresMedically reviewed

DEXA, InBody and smart scales measure body composition differently and disagree with each other. Here is what each is good for, and Singapore costs.

Protein powder in Singapore: how to choose, when it helpsMedically reviewed

A tub of protein powder is very probably regulated as food by SFA, not as a supplement by HSA. What that means, whether whey beats plant, when it helps.

Resistance training on GLP-1: the minimum that worksMedically reviewed

You do not need long sessions or heavy weights to protect muscle during weight loss. Here is the least training the evidence supports, and why it works.

Strength as a vital sign: track performance, not kilogramsMedically reviewed

Strength is worth tracking in its own right and predicts hard outcomes. What it cannot do is tell you whether you are keeping muscle. Both halves matter.

Appetite after stopping GLP-1: what is known and what is notMedically reviewed

No withdrawal trial measured appetite after stopping. Here is what was measured, what the drug half-life implies, and why the distinction matters.

How much weight comes back after stopping GLP-1?Medically reviewed

Trial data puts roughly two-thirds of the lost weight back within a year. The parts of that number that usually get dropped.

Maintaining a loss without medication: what carries itMedically reviewed

Once the appetite effect stops, something else has to hold the result. What the withdrawal trials measured, and what they never did.

Tapering off GLP-1: what the evidence actually showsMedically reviewed

GLP-1 withdrawal trials tested stopping abruptly, not tapering. Here is what that absence of evidence means for planning an exit.

The habits that predict keeping weight offMedically reviewed

Registry data on people who kept large losses off for years points at a short list. Here it is, with the limits of the evidence stated honestly.

Treatment length on GLP-1: what has been testedMedically reviewed

No trial has compared one treatment duration with another. The longest exposure data, when the curve flattens, and what decides duration.

What an exit plan contains, and when to build itMedically reviewed

Regain after stopping is well documented. What designing the exit at the start actually consists of, and what has never been tested.

What is the weight you regain actually made of?Medically reviewed

No GLP-1 trial has measured whether regained weight comes back as fat or muscle. Here is what is known, what is assumed, and why the distinction matters.

Alcohol on GLP-1: what changes and what is unknownMedically reviewed

Many people report drinking less on GLP-1 medication, and trials are testing it. Here is what is established, and what the labels do not say.
