Two-thirds.
That is how much of the lost weight was regained after they stopped the treatment.
The number comes from the follow-up part of one of the biggest weight-loss medication trials ever done. People in the trial had dropped an average of 17.3% of their body weight in 68 weeks. Then they stopped taking the medication, and the support for healthy habits ended too. A year after, that group was only 5.6% below where they started. No one in that study was lazy. Each person had shown, while being watched and checked, that they could lose weight.
The study looked at what happens when the support is taken away.
The real thing to ask when you look at the two ways people in Australia buy medical weight loss online right now is this. The first way is simple. You fill out a quick form, have one talk with an Australian telehealth clinic, get what you need, and that’s it. The other way is a plan where a doctor checks in every month as your body deals with the changes.
It will try because that is what happens. This is not just a feel-good saying. It’s about how the body works.
The two models, in plain English
Single-consult: You fill out a form, have one talk with a doctor, and get a prescription. It is fast and not costly at the beginning, with no extra need to sign up long-term. If you want a different dose or need another prescription three months down the line, you usually pay for another talk and do all of it again.
Monthly care: You pay a set fee each month. This amount covers a call with your doctor that happens at set times, getting your medicine renewed when you need it, and changing the dose as you go. NextClinic uses this model to work. You pay $89.90 for your first fifteen-minute meeting and phone call with a doctor who is AHPRA-registered. After that, you pay $49.90 a month with the self-dispense plan. The monthly call is already included in this price, and you are not charged extra for it.
The price is the easy thing to spot between them. But, out of all things, it’s not the most interesting one. If you total six months of re-consult fees with a one-time consult service, you may find the totals are closer than you might think.
The thing that matters starts to show around month three.
Month three is where it gets strange
You will likely have a good first six or eight weeks. Most people feel that way at the start. The hard part begins after this, and it often comes as three things at one time.
The scale stops changing. You did not stop what you were doing. A smaller body uses less energy than before. It also uses a bit less energy than you might think from doing math. At the same time, your hunger hormones start to do the opposite. You feel hungry again around 4pm. Food amounts that felt right in week five feel too small in week fourteen. This is a normal thing that happens to the body when you lose weight. It is not because you do not want it enough.
Next, the side effects that were ok at first start to feel harder. Nausea, reflux, constipation, and the feeling that eating is work. A lot of this can get better if you change when you take it or adjust the plan. If you have a doctor you can call, you can fix it fast. If not, you just deal with it or stop without saying much.
Third, and this is what makes most clinicians feel sick: people begin to change their own dose. They skip a week because they feel bad, and then they take more to make up for it. They make a prescription last longer by going every ten days instead of every seven days. No one means to do this. It happens because there is no one to talk to, and stopping feels like you did not do well.
None of that means getting help is a bad idea. It means the first six months are not a good time to be alone.
A monthly review helps catch these things early. Your doctor can see when your numbers stop changing before you feel like giving up. A problem gets solved with a new plan instead of you wanting to quit. The speed at which you lose weight stays good. This helps protect your muscles. This is very important because losing weight fast can take away both fat and muscle. Muscle is what helps keep your body running well after you lose weight.
Side by side
| Single-consult provider | NextClinic monthly plan | |
| How it works | One-off consult, one-off script | Ongoing plan with a scheduled doctor call every month |
| What you pay | Low fee upfront, then a new consult fee each time you need something changed | $89.90 to start, then $49.90/month self-dispense, check-ins included |
| Dose changes | Standard schedule, adjustments usually mean booking again | Adjusted by your doctor as your response and tolerance change |
| When you plateau | You work it out yourself, or pay for another appointment | Reviewed at your next check-in, with the plan adjusted |
| Side effects | Ring your GP, or wear it | Raised on your monthly call and managed |
| Reaching a doctor | Effectively ends after the first consult | Monthly call plus support through the app or email |
| Best suited to | People already stable on a treatment who just need continuity of supply | People starting out, or anyone who’s regained before |
| The catch | Support disappears exactly when it starts to matter | You have to actually show up to the monthly call |
So which one wins?
For most people who start with nothing, the monthly plan works best. This is not because the medicine changes, but because all that comes with the medicine does.
It’s good to be clear about what this claim really means. A monthly plan won’t make sure you lose weight or keep it that way. Nobody can promise you this, and you should be careful with any clinic that does. A plan can help you stay with a treatment that works for you long-term, rather than dropping it after a few months.
Single consultations may suit people who are stable on the same treatment and only need occasional prescriptions.
That way, you avoid paying for monthly reviews you don’t actually need.
Before signing up, make sure a doctor speaks with you in real time rather than relying only on a questionnaire.
A phone call is enough; you do not need a video consultation.
If a service offers treatment without any real-time doctor consultation, consider it a warning sign.
Here are some other things you should look at before you give your card number:
- Are the doctors AHPRA-registered, and does the site say this clearly?
- Is there an Australian address and ABN listed on the page?
- Does the site send out medicine from another country instead of giving you an eScript you can use at an Australian pharmacy? The TGA has found fake weight-loss injectables at the border, so this risk is not just a guess.
- Can you quit without a problem? With NextClinic, you stop your plan with one support email. If the doctor says you should not get the treatment after your first chat, you get your money back.
Also, and this is more important than everything else here: taking medicine is not the right choice for everyone. If you are pregnant, or if you have had problems with eating in the past, you should see someone in person. Do not use an online program for this. A good clinic will tell you this and will not just take your money. If a doctor chooses not to give you medicine, it means the system is doing what it should.
The short version
One meeting may help you start. But it will not help when your body starts to fight against you, and that will happen to everyone no matter how eager you feel when you first begin.
If you have lost weight before but then saw it come back, you know that the hard part is not dropping the first ten kilos. It is about being there in month nine that matters most. Pick the model that lasts that long.
