The story01
Which apple cider vinegar weight loss study was retracted?
It was a March 2024 trial in BMJ Nutrition, Prevention and Health, run in Lebanese adolescents and young adults with overweight or obesity.
About 30 people per group drank 5, 10 or 15 mL of vinegar a day for 12 weeks. The paper first reported average losses of 6 to 8 kg, which is much larger than earlier work (BMJ Group, ACV trial retracted (2025)).
The retraction02
Why was the vinegar trial retracted?
Because outside statisticians could not reproduce the results. They found multiple errors, implausible statistics and irregularities in the data set (BMJ Group, ACV trial retracted (2025)).
The trial was not registered ahead of time. The authors called the problems honest mistakes and agreed to the retraction, announced September 25, 2025 (BMJ Group, ACV trial retracted (2025)).
| Item | What the notice says |
|---|---|
| Original claim | Average losses of 6 to 8 kg |
| Doses | 5, 10 or 15 mL vinegar daily for 12 weeks |
| Problem | Could not be replicated; errors and irregularities |
| Advice | Results should no longer be referenced or used |
What remains03
What does the rest of the vinegar research show?
It shows small effects. The older Japanese trial found about 1 to 2 kg lower weight on 15 or 30 mL of vinegar a day, and weight drifted back after people stopped (Kondo 2009, vinegar trial).
A 2025 review of 10 trials found small average effects with large differences between studies, and it had included the trial that was later retracted (Castagna 2025, ACV meta-analysis). Mayo Clinic says vinegar is not likely to cause weight loss (Mayo Clinic, ACV for weight loss).

What does this mean for Jellutide?
It means no study backs big numbers for vinegar, and none tested Jellutide itself.
The sales page makes bold promises, which we quote only to check them. The label is milder: "Supports Metabolism* · Helps Support Weight Management* · Natural Ingredients"
The label vs sales page comparison shows where the two disagree. The claims below sit next to the evidence.
- Sales headline“Melt away stubborn fat and reclaim the body you had in your 20s - in less than a month”No trial has tested the gummy. The best-known vinegar trial found 1-2 kg over 12 weeks, and a trial reporting bigger losses was retracted. (Kondo 2009, vinegar trial) (BMJ Group, ACV trial retracted (2025))
- Around-the-clock claim“24/7 automatic fat-burning”No ingredient on the label is shown to burn fat around the clock. About 27 mg of BHB salts is far below the 10-40 g used in ketone studies. (Evans 2022, exogenous ketone review) (Buga 2021, ketone salts + diet trial)
- GLP-1 copy“GLP-1 activation”GLP-1 medicines are prescription drugs, mostly injected. No study shows this gummy acts like one, and experts call GLP-1 supplement labels misleading. (NIDDK, Prescription weight medicines) (Harvard Chan, GLP-1 supplements)
- Evidence claim“clinically proven”No clinical trial of the product is published, and none is shown on the sales page. Health claims need real evidence. (FTC, Health Products Compliance Guidance)
- Ingredient claim“NO STIMULANTS”True of the label formula. The sales page's own list, though, names guarana and green tea, which contain caffeine. (MSKCC, Guarana) (Jellutide sales page)
- Safety claim“no significant side effects”Not backed by data on the page. Vinegar is acidic, and the label itself asks people on medication to check first. (Mayo Clinic, ACV for weight loss)
- Bottle front“Weight Loss Support*” with the FDA asteriskStructure/function wording, allowed with the FDA statement. It is not a disease claim and not FDA approval. (21 CFR 101.93 (structure/function))
Claims as printed on the sales page (Jellutide sales page) and the label. Health claims need competent and reliable scientific evidence (FTC, Health Products Compliance Guidance).
Reading claims05
How can you spot a shaky weight loss study?
Look for results that are far larger than earlier work, no trial registration, and no outside replication.
The FTC says health claims need competent and reliable scientific evidence, and that testimonials alone are not enough (FTC, Health Products Compliance Guidance). Ask whether the study tested the exact product you are buying.

FAQ06
Questions about the retraction
When was the apple cider vinegar study retracted?
BMJ Group announced the retraction on September 25, 2025, with a notice dated September 23, 2025 (BMJ Group, ACV trial retracted (2025)). The trial had been published in March 2024.
Who ran the retracted vinegar trial?
It came from researchers working with Lebanese adolescents and young adults, published in BMJ Nutrition, Prevention and Health. The authors called the problems honest mistakes and agreed to the retraction (BMJ Group, ACV trial retracted (2025)).
Are other vinegar studies still valid?
Other trials stand, but they show small effects, such as about 1 to 2 kg in one 12-week trial (Kondo 2009, vinegar trial). A 2025 review shows high variation and counted the retracted one (Castagna 2025, ACV meta-analysis).
Was there a warning before the retraction?
According to Retraction Watch, as summarized in our source notes, no expression of concern was posted before BMJ retracted the paper (BMJ Group, ACV trial retracted (2025)).
