Getting lean, explained honestly.
Evidence-based articles on GLP-1 medication, protecting your strength while the weight comes off, and keeping the results — written for a Singapore reader. Every clinical claim carries a citation.
Don't want to be on GLP-1 for life? GetLean's programme in Singapore is designed to get you off it: exit planned at your first consult, then a taper.
There is no fixed number of months. How the length of GLP-1 treatment is set: the goal, a planned pace, the plateau and the taper.
Looking for a GLP-1 taper schedule in Singapore? The trials took the medication away. How a planned taper differs, and what replaces its effect.
How to stop GLP-1, where clinically appropriate, with a planned taper. In the trials the medication was taken away and most of the weight returned.
CagriSema is not registered in Singapore and not approved anywhere. Submitted to the US FDA in Dec 2025. What REDEFINE 1 and REDEFINE 4 reported.
Dr Quek is comfortable keeping a patient on Mounjaro 2.5 mg, the lowest dose, if they stick to nutrition and exercise. Off-label: what the studies show.
Plain answers to common GLP-1 questions in Singapore: side effects, how often, food and coffee, MediSave, switching doctors. Education, not advice.
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.
Most trial participants reached 5% weight loss and a minority did not. The full responder ladder, the placebo arms, and why no predictor exists.
Foundayo is orforglipron, a daily GLP-1 tablet approved in the US and UK but not registered in Singapore. What it is, and how it differs from the tablet here.
Foundayo (orforglipron) side effects and stopping rates from the US label, what the main trials found, and where it stands in Singapore.
GLP-1 medications mimic a gut hormone signalling fullness and slowing gastric emptying. The brain mechanism, food noise, and Singapore prescribing rules.
GLP-1 medicines are Prescription Only in Singapore. Here is which products are registered, what the law says, and how licensed treatment works.
Is retatrutide available in Singapore? Not as a registered medicine. It is not on HSA's register (checked 8 October 2026) and HSA warns against online "reta".
Mounjaro injection cost in Singapore at GetLean: S$488 a month at 2.5 and 5 mg, S$788 at 7.5 and 10 mg, S$1,088 at 15 mg, all-in. Book your S$20 consult.
Which weight-loss medicines are approved in Singapore, which only abroad, which are in trials, and what each shows about stopping. Status at 9 Oct 2026.
Novo Nordisk's triple agonist is UBT251, in phase 2. Zenagamtide (amycretin) is in phase 3. Both are investigational; neither is registered in Singapore.
Reta is not an approved medicine anywhere. What HSA, Malaysia's health ministry and Victoria's health department warned, and what they report.
"Reta" sold online is not an approved medicine anywhere. What HSA warned on 25 September 2026, and why a "research use only" label is a warning sign.
At GetLean, Rybelsus (oral semaglutide) is S$288 a month at 3 mg and S$388 at 7 and 14 mg. Registered here for type 2 diabetes, so for weight it is off-label.
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.
GLP-1 was not found in lizard venom — exendin-4 was, from a separate gene. What the 1992 paper reported, and why the credit is still contested.
Singapore's Wegovy label includes an optional 7.2 mg weekly dose, given as three 2.4 mg injections. What the label says and what the STEP UP trial found.
The Wegovy pill is a daily semaglutide tablet approved for weight loss in the US, UK, UAE and EU, not registered in Singapore. How it differs from Rybelsus.
Wegovy cost in Singapore at GetLean: S$488 a month at 0.25 to 1 mg, S$788 at 1.7 and 2.4 mg, S$1,088 at 7.2 mg, all-in. Book your S$20 consult.
Semaglutide (Wegovy, Ozempic) against tirzepatide (Mounjaro, Zepbound) in the SURMOUNT-5 head-to-head, and what is registered in Singapore.
Patients described it before researchers named it. The first validated measures appeared in 2025. Here is what is established and what is not.
The dose climbs in fixed steps over months. The schedules are identical across the US, EU and Singapore — the tolerability wording is not.
Semaglutide stays in the circulation for five to seven weeks after the last dose. What the labels and the STEP 1 extension show about the months after stopping.
What happens to appetite after stopping GLP-1 medication: what the trials measured, what the half-life implies, and what to build while it still works.
Once the appetite effect stops, something else has to hold the result. What carries a loss after GLP-1 medication, and how a planned taper fits in.
Maintenance calories are an estimate of resting energy, movement and digestion. How it is worked out, why it falls after weight loss, and how to check it.
Tirzepatide's half-life is about five days, so its effect fades over weeks. What the labels and SURMOUNT-4 show about the weeks and months after stopping.
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.
Neither label describes a withdrawal syndrome or dependence. What stopping does is let the effects wear off. What is documented, and what is not.
GLP-1 microdosing has no published trial yet. At GetLean, microdosing means taking the medicine below its labelled dose or schedule, set with Dr Quek.
A trial has tested stepping down. In SURMOUNT-MAINTAIN, 5 mg tirzepatide held more weight off than stopping, and less than the full dose.
A pause is a short gap that ends in a restart; stopping is the exit. What the labels and guidance say about holidays, illness, Ramadan and surgery.
Restarting GLP-1 medication after regain is common, and rebound is not failure. How often people restart, what weight cycling does, and how a restart works.
Most guidance now says to keep taking it before surgery, with a liquid diet the day before for some. What the 2024 and 2025 guidance and the labels say.
In the STEP 1 extension the medication was stopped overnight, with no taper; about two-thirds of the lost weight came back in a year. What usually gets dropped.
A GLP-1 tablet leaves the body over weeks. What the labels show, what the injection trials cover, and what stays the prescribing doctor's decision.
GetLean helps patients in Singapore taper off Mounjaro and other GLP-1 medication, where clinically appropriate. Video consults, monthly dose reviews.
'Toned' is a ratio — muscle present, fat over it reduced. There is no toning exercise: taken to failure, light and heavy loads build similar muscle.
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.
Programmes are judged on kilograms because that is what the trials measured. What that metric cannot see, and what closing the gap would take.
No official healthy range exists. The most-quoted paper puts Asian women at about 25–36% and men at 13–24% between the BMI lines. Where that comes from.
One sub-study puts lean mass at a quarter of the weight lost on GLP-1 medication, a review of another nearer 40% — in the first, placebo lost the same share.
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.
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.
One tape measure, one division, and a boundary that outperformed BMI across 78 studies. Here is how to use it and what it does and does not tell you.
"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.
A concrete week: a protein target with the right denominator, two or three hard resistance sessions, walking, the injection day, and what to measure.
Phase one takes the fat off. Phase two holds it: the habits, the training and, on medication, the planned taper. What each phase is for.
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.
Body weight reports total mass, not what it is made of. What to track instead during treatment, and the evidence behind each alternative.
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.
One Singapore provider listed a DEXA scan at $308.47 and an InBody test at $43.60 in July 2026. Which is more accurate, and why to stick to one device.
Bands match weights for strength and the size evidence is thinner than the internet suggests. What decides it is progressive overload.
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.
Twelve tactics for reaching a daily protein target when food has stopped being appealing, sorted by sequencing, density and format.
The severity of the deficit clearly changes what you lose. Whether speed matters independently is contested — two trials say yes, one says no.
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.
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.
Walking is superbly evidenced for how long you live and poorly evidenced for what you are made of. Singapore survey data shows the gap.
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.
Total daily protein dominates and timing is second-order. The per-meal numbers in circulation were derived in people who were not dieting, and ours are.
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.
In the key trial, total weight lost was identical between short and adequate sleep. What changed was the composition. Plus what nobody has tested.
Marks at the injection site are uncommon — 1.4% against 1% on placebo. What the labels record, what nobody has published, and the short list to act on.
Gallstones are a known consequence of losing weight quickly, by any method. What the labels report, who is at higher risk, and the symptoms to act on.
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.
Constipation affects about a quarter of people on GLP-1 medication. Here is what the evidence supports doing about it, and what it does not.
One small claims study reported a nine-fold rate. Large randomised trials do not show an elevated risk. What the label warns, and what to watch for.
The warning comes from rodent studies, the contraindication is not the same in every country, and the human research genuinely disagrees with itself.
In the trials, participants with type 2 diabetes lost less weight than those without. Why the gap is unexplained, and where hypoglycaemia risk sits.
Fatigue is a listed adverse reaction in both labels; muscle cramps are not listed in either. What that distinction means for training in a deficit.
Pre-conception washout differs by drug and by document. The tirzepatide contraceptive interaction splits US and EU. Pregnancy-outcome studies disagree.
Slowed stomach emptying can change how oral medicines are absorbed. Why your full medicine list belongs with your doctor and pharmacist.
Where to inject, how long a pen keeps, why it flies in the cabin not the hold, the dose day across time zones, and what Changi and four countries allow.
Hair loss is a listed adverse reaction in both labels, far more often in women. It is telogen effluvium from weight loss, and it is usually temporary.
Do not give yourself another dose to make up a suspected partial one. What is documented, what has never been studied, and what to tell your prescriber.
An oral GLP-1 is registered in Singapore. Its registered indication is type 2 diabetes, not weight management, so using it for weight is off-label.
The longest GLP-1 trials ran three to four years in narrow, specific populations. What they found, who they enrolled, and what still has no long-term data.
Singapore's instruction counts days since the missed dose. The US one counts days to the next. Here is what applies if you are treated here.
Nausea affects a large minority on GLP-1 and clusters around dose increases. Here is what the trials show, and why the diet advice is not evidence.
"Ozempic face" is fat loss showing in the face, and it tracks the weight lost rather than the medicine. One 2025 study put a number on it for the first time.
Most GLP-1 side effects are gastrointestinal and transient. Serious problems are rare. Here is an honest, tiered picture with incidences from the trials.
Most GLP-1 side effects are unpleasant rather than dangerous. A short list is neither. Here is what the product information says to act on.
Who cannot take GLP-1 medication? Singapore's label lists one contraindication; the US label adds medullary thyroid cancer and MEN 2. What doctors screen for.
The first dose is the smallest of the schedule. What the labels say about sites and timing, what happens afterwards, and why the pen steps are not here.
Singapore uses 23 and 27.5 rather than 25 and 30. Here is the body-composition research behind that, measured largely in Singaporeans.
Our criteria are a BMI of 25 or more. Anyone can book the first consultation and Dr Quek decides there whether a GLP-1 medication suits you.
An overseas doctor prescription is not valid in Singapore. Personal import of your own prescribed medicine is. Those two get conflated.
Residency does not decide who may be prescribed for; a passport or FIN satisfies the rule. Where it matters is Medisave, which generally does not cover this.
Three lawful supply routes, what the labels say about keeping a pen, and why Singapore's delivery standard cannot be quoted here: its text is not public.
Nine questions that separate a medical service from a subscription. Criteria rather than names, with the evidence behind why each one is worth asking.
Four things anyone can check before paying: the licence, the doctor register, whether a live video consultation happens, and the product.
Few studies compare telemedicine with in-person care for weight-loss medication. Here is what each route is set up to do, and what the rules require.
A first visit here needs a live video consultation and enough history to assess you. What gets asked, and what people leave out.
No product label in the US or EU requires a blood test before starting GLP-1 medication for weight management; Singapore's is not public. Here is what they say.
Your first online GLP-1 consultation in Singapore is a video call: what to prepare, what the doctor assesses on the call, and what follow-up looks like.
The figure traces to a 1959 review plus 100 clinic patients, and no source states 95%. What it measured, and the share who succeed long term.
Caffeine, CLA and berberine produce small pooled effects, and the two berberine meta-analyses disagree. What the trials report, and what 'natural' means.
Aerobic exercise alone produced about 2.8 kg at 150 minutes a week. Added to a deficit it prevented roughly 46% of fat-free-mass loss. What each arm did.
Across 28 trials, intermittent fasting matched ordinary dieting for fat loss and cost slightly more fat-free mass. No trial has combined it with a GLP-1.
Pooled randomised evidence gives bariatric surgery about ten percentage points more weight loss than GLP-1 medication. Few trials compare them directly.
In a metabolic ward with energy and protein fixed, a ketogenic diet slowed fat loss while scale weight accelerated. The first week is glycogen and water.
Three weight-management medicines were registered here before the GLP-1 class arrived, and all three still are. What changed is the size of the effect.
Slimming treatments in Singapore, from fat-freezing to HIFU, are measured on fat thickness and circumference at the treated spot, not on body weight.
Chinese herbal medicine showed an adjunct signal in a high-bias evidence base. Green tea produced a small, non-significant loss in Cochrane's review.
Built on HPB's own composition data rather than brands: what belongs in the trolley when you are protecting muscle, and how to read a Singapore label.
HPB's database covers cai fan and prata clearly and has no mala xiang guo record at all. What the figures show, and why the third number cannot exist.
Sitting has a large mortality evidence base and almost none for body composition. What the numbers support for a desk job, and what a week can look like.
Singapore has over 3,400 outdoor fitness corners, and their equipment is fixed-resistance — the load cannot go up. Here is how progression works anyway.
Eleven Singapore hawker dishes with laboratory-measured energy and protein, ranked by protein per calorie — and why the top is not the best pick.
HPB puts a kopi at 193 kcal and 19.05 g of sugar, and kopi O kosong at 33 and none. Why the siu dai claim falls apart, and what Nutri-Grade covers.
ActiveSG membership is free, and gym entry was $2.50 for a citizen or PR aged 18–54 as at 1 August 2026. What that buys, and what to do inside.
Shift work is associated with higher rates of overweight and obesity. In an analysis that splits by study design, the cohort estimate is smaller.
Obesity rose from 10.5% to 12.7%. Diabetes stayed stable at 9.1%. The four ways Singapore's national health figures get misquoted, corrected.
On a suppressed appetite the limit is volume, not calories. Five ordering rules, built on HPB portion weights.
At a shared table you do not control portions — you control the order sheet. What to put on it, and how to serve yourself when the dishes arrive.
No registered weight-management trial of these medicines has enrolled anyone below BMI 23. For someone already lean, the evidence points elsewhere.
After 40, muscle loss and reduced protein response make getting lean harder — more protein and resistance training become non-negotiable, not optional.
The 2023 international guideline mentions GLP-1 medication for weight in women with PCOS — as a consensus recommendation, not as PCOS treatment.
Metabolically healthy obesity is usually a phase, not a type. Around 40 to 50% convert over 10 to 12 years, and the comparison group decides every risk number.
No trial has tested weight loss to a deadline. A prospective study of brides found they did not lose weight before the wedding and gained about 2 kg after.
No trial of GLP-1 medication has been run in adults over 65, and none measured muscle. What is strongly evidenced after 60 is resistance training.
Men carry more of their fat viscerally. Two things commonly said about that are wrong, and the corrections are more useful than the claims.
Menopause does not accelerate weight gain — it changes what the weight is made of. Here is what the DXA cohorts measured, and what nobody has measured.
The SAF publishes one weight figure and it applies to pre-enlistees only. For most younger men the useful evidence is about running and lifting together.
No published source sets a timing rule for starting a GLP-1 after birth, and the breastfeeding instruction differs by drug, by document and by country.
About 1 mm Hg per kilogram in the trials, lasting where the weight stayed off. What the evidence supports, and two famous figures that measure something else.
The dose-response is real and steep. The part usually left out is how few people in the study reached the amount of weight loss that produced it.
Prediabetes moves in both directions. In Singapore's own eight-year study, more people reverted to normal than developed diabetes.
Weight loss improves obstructive sleep apnoea and rarely resolves it. What the randomised trials found, and why Singapore has no national figure.
In a Singapore community study, 91% of people with moderate-to-severe sleep apnoea did not know. The signs that predict it come from outside, not inside.
A dark velvety patch on the neck will not scrub off, because it is not dirt. What the skin can suggest about insulin, and why only a blood test answers it.
What the class is, what it does to appetite, what it does not do, and how licensed supply differs from the grey market in Singapore.
No trial has compared Foundayo (orforglipron) with the Wegovy pill directly. Their separate trial results, how each is taken, and where they stand in Singapore.
No trial comparing Reta (retatrutide) with Mounjaro directly has reported results yet. Their separate trial results, and which one is registered in Singapore.

Ozempic and Wegovy are the same medicine, semaglutide. At GetLean it is S$488 a month at 0.25 mg, 0.5 mg and 1 mg, prescribed as Wegovy, all-in.
Reta vs Mounjaro and Foundayo vs the Wegovy pill: what each separate trial found, how it was counted, and which medicines are registered in Singapore.
Saxenda is liraglutide, a once-daily GLP-1 injection still registered in Singapore for weight management. How it compares with Wegovy and Mounjaro.
Wegovy and Ozempic are both semaglutide. At GetLean it is prescribed as Wegovy: S$488 a month at 0.25 to 1 mg, S$788 at 1.7 and 2.4 mg, S$1,088 at 7.2 mg.
Zepbound and Mounjaro are both tirzepatide. At GetLean it is prescribed as Mounjaro: S$488 a month at 2.5 and 5 mg, S$788 at 7.5 and 10 mg, S$1,088 at 15 mg.
A resistance stimulus and enough protein are the two inputs the evidence supports. How much of each, and what helps less than advertised.
Tau kwa, house-brand oats and peanut butter, and a 15-egg pack gave the most protein per dollar of 48 FairPrice foods priced on 7 October 2026.
What settles, what is serious and when to call a doctor, read against Singapore's label. At GetLean, daily WhatsApp coaching fills the gap between reviews.
Mounjaro (tirzepatide) side effects from its US and EU labels: nausea in 25% to 29% against 8% on placebo, how long they last, and the serious ones.
Sick on GLP-1 medication and your next review is months away? What is normal, what helps, when to get help, and how daily WhatsApp coaching at GetLean fits.
Nausea, diarrhoea and a skin sensation called dysesthesia led the list in Lilly's phase 3 retatrutide trials. The rates by trial and dose, and who stopped.
Wegovy (semaglutide) side effects from Singapore's insert and the US label: nausea in 44% against 16% on placebo, how long each lasts, and the serious ones.
Who a service can assess, what a consultation is required to involve, how the medicine is lawfully supplied, and what Medisave does and does not cover.
Yes. In Singapore an online doctor can prescribe GLP-1 for weight loss after a live video consult. How it works at GetLean, step by step, with Dr Quek.
If your clinic stops prescribing or your GLP-1 medication runs out, do not stop or change it alone. What a new doctor assesses and how a gap is handled.
Obesity is not one of MediSave's 23 chronic conditions, no GLP-1 for weight is on MOH's subsidised lists, and the Shield plans checked exclude weight treatment.
Transferring a GLP-1 prescription in Singapore means a new assessment. At GetLean: share your medication and dose, bring records, see Dr Quek by video.
11 questions to take to your doctor before a first dose of Mounjaro (tirzepatide): the Singapore label, tests, pregnancy, side effects and how treatment ends.
Tirzepatide and semaglutide are prescription-only in Singapore. See where a doctor can prescribe them, which clinics do Mounjaro, and how GetLean does it.
Any clinic can be checked in a minute: the HCSA licence, the doctor's SMC registration and a live video first visit. GetLean's licence is the worked example.
Weight-loss options in Singapore compared: lifestyle, medication, slimming treatments and bariatric surgery, including what Medisave covers.
Weight loss injections in Singapore are prescription GLP-1 medicines such as Mounjaro and Wegovy, not fat-dissolving injections: types, cost, side effects.
The same principles as the rest of this site, translated into hawker portions, public gyms, desk hours and rosters — with the local data named.
The Ramadan guideline names three older GLP-1 medicines, not tirzepatide or semaglutide. What it, MUIS and the labels say, and HPB's Hari Raya food figures.
HPB puts a 94 g slice of bak kwa at 370 kcal and a 20 g pineapple tart at 93. What the labels say about appetite and nausea, and what they say nothing about.
Singapore's guideline puts eating to lose weight at least 500 kcal below estimated needs. Two worked examples, with a day of hawker food at each level.
