Before Starting Medical Weight Loss: What Patients Should Know
A pre-treatment checklist from a Singapore family physician: what assessment involves, what questions to ask, and how to spot a responsible programme.
Starting medical weight loss is a decision worth making carefully. Singapore’s market has everything from doctor-led clinical programmes to commercial slimming packages, and the difference matters for both your safety and your money. Here is what a family physician wants you to know before you start.
1. Assessment comes before anything
A legitimate medical weight loss programme begins with assessment: your history, current medications, examination, measurements, and relevant blood results. The doctor is establishing why your weight is where it is: thyroid problems, medication side-effects, sleep issues and metabolic conditions all present as “can’t lose weight”.
If a programme sells you a plan before anyone has examined you, that is the first red flag. At Accord, every plan begins with a clinical assessment, and nothing is recommended before it.
2. Ask about the doctor
Who assesses you, prescribes (if anything), and follows you up? A clinical programme should have one accountable doctor throughout. Weight management is chronic care, and being handed between different staff at each visit dilutes the judgement that matters.
Ask: Will I see the same doctor at every visit?
Two checks help before you commit. The first is registration: every doctor practising in Singapore must be registered with the Singapore Medical Council, and a clinic that hesitates when you ask has already answered the question for you. The second is structure: is the doctor running your care from assessment through follow-up, or is their involvement limited to signing off a package run by someone else? The person prescribing and monitoring your treatment should know your history, not just your file number.
3. Pricing should be transparent
Before you commit, the costs should be clear: consultation, follow-ups, any programme fee and, where relevant, the range for prescription medicine.
When a clinic can’t or won’t explain pricing up front, walk away. Our cost page publishes the full breakdown, and the policy is simple: costs are confirmed before anything is arranged.
4. Beware of guarantees
Anyone promising a specific number on the scale is selling hope, not medicine. Clinically meaningful results take time, and individual response varies widely. The WHO classifies obesity as a chronic, relapsing disease, which is exactly why “lose 10 kg in a month” framing should set off alarms. A responsible doctor will give you a realistic range and a timeline, then review the plan when results don’t match expectations.
5. Understand the role of medication
Prescription weight-loss treatment such as the GLP-1 class is a tool within a programme rather than the programme itself. In Singapore it is prescription-only, which means a doctor must assess, prescribe, dose-escalate and monitor you. Ask what happens around the medication: diet, activity, sleep and follow-up are the programme. A plan with nothing to say about any of them is not managing your weight, only prescribing for it.
6. Plan for the maintenance phase
The hardest phase of weight loss is keeping it off, and the questions that matter come after you reach your target: how reviews change, how habits are reinforced, and what the exit plan looks like. Programmes that ignore maintenance are programmes you’ll need twice.
A credible programme has specific answers. Reviews that continue at a slower cadence (monthly, then every few months). Measurements and bloods repeated at sensible intervals rather than quietly dropped. And an honest conversation about medication: whether it continues, changes or stops, and what that means for your weight afterwards. If the only answer to all of this is “keep buying the plan”, that is an answer too.
The checklist, in one breath
- Assessment first — no plan before examination
- One accountable doctor — from first visit to follow-up
- Pricing up front — costs confirmed before you commit
- No numbers promised — results framed as a range, not a guarantee
- Medication in its place — one tool within a broader plan
- A maintenance phase — a real answer for the years after
If a programme ticks all six, you’re in good hands. If it can’t answer any of them, keep looking, and book a consultation somewhere that can.
Frequently asked questions
Do I need blood tests before starting medical weight loss?
Often, yes — metabolic markers, thyroid and liver/kidney function can all affect both the cause of weight gain and the safety of treatment. A doctor decides what is useful for your individual case; not everyone needs the same panel.
How do I know if a weight loss programme is legitimate?
A responsible programme starts with assessment before selling anything, is led by a registered doctor, publishes its pricing, and monitors you rather than sending you off with a meal plan. Be wary of guarantees, before-and-after marketing and upfront packages.
Can I start medical weight loss if I'm on other medications?
Possibly — but the doctor must review every medication you take, because interactions and contraindications exist. Bring your complete medication list (including supplements) to the first visit.
What should I bring to the first consultation?
Your medication list, any recent blood test results, and a rough history of what you've tried before. You don't need to fast for the first assessment unless bloods are ordered at the visit.
