The phrase josie gibson weight loss gets searched thousands of times a month. The results are a mix of magazine headlines, publisher blurbs and aggregator sites that copy from each other, and the figures don’t agree. Below we separate what each source actually says and flag what nobody has confirmed.
Josie Gibson’s weight loss: the latest verified update
These are the points we can tie to a named, public source:
- She has written a diet book. The Josie Gibson Diet is published by Pan Macmillan. The publisher’s listing says she lost over 5 stone in six months and went from a size 20 to a size 10. This is promotional copy from the publisher, not an independent or medical measurement.
- She fronted a Channel 5 diet series. Channel 5’s press office (Paramount) announced the show on 12 March 2025, under the working title The 1970s Diet. The press release says a doctor and a nutritionist designed the diet and that her weight, health and fitness would be monitored during the experiment.
- The series was broadcast as The 1970s Diet: Could It Work for You? TV listing databases show it as a two-part series airing in January 2026.
Josie Gibson has not publicly disclosed any medical diagnosis or condition linked to her weight, and we don’t suggest one.
Timeline of public statements
Most confusion comes from mixing up two separate things. One is her earlier personal weight loss, which the book covers. The other is the 2025–26 TV experiment. The table keeps them apart.
| Date | Event | Source | What it claims |
|---|---|---|---|
| 2010 | Wins Big Brother 11 | Broadcast record | The start of her public profile. No health claims involved. |
| Book publication (Pan Macmillan) | The Josie Gibson Diet is released | Publisher listing | Over 5 stone in 6 months, size 20 to size 10 |
| 12 March 2025 | Channel 5 announces The 1970s Diet (working title) | Paramount press release | The diet is designed by a doctor and a nutritionist, and she is monitored on weight, health and fitness |
| January 2026 (as listed) | The 1970s Diet: Could It Work for You? airs in two parts | TV listings (TheTVDB, IMDb) | Episode metadata only |
| Ongoing | Magazine coverage, including Hello! | Celebrity press | A headline of “5 stone in 3 months” linked to a “1970s diet” |
Where the reported figures conflict
You’ll see three different versions online:
- The time frame. The publisher says six months. A widely shared Hello! headline says three months.
- The dress size. The publisher says a size 10. At least one low-authority aggregator says a size 8.
- The method. Some articles credit the whole loss to the “1970s diet”. The publisher’s description of the book comes before the Channel 5 series, so the two can’t be the same thing.
Our position is simple. The publisher’s figure has a named source, so we attribute it to them. We treat the other figures as unconfirmed unless a primary interview turns up that supports them.
What the 1970s Diet show actually tested
The Channel 5 series was a TV experiment, not a record of how she lost weight originally. According to the press release, the format was:
- A diet based on how people in Britain typically ate in the 1970s, before ultra-processed food and constant snacking became common.
- A plan designed by a doctor and a nutritionist, not by Josie herself.
- Monitoring of her weight, general health markers and fitness during the experiment.
The press material we reviewed doesn’t publish outcomes. Any specific result attributed to the series, such as a number of pounds lost or changes in blood markers, should come from the broadcast itself. Where an article doesn’t say which episode a figure came from, treat it with caution.
One more practical point. A short, supervised TV experiment and a long-term diet you follow on your own are not the same. The first comes with professional monitoring. Most people at home won’t have that.
Confirmed health claims and what remains unverified
Did Josie Gibson use Ozempic or weight-loss jabs?
Several aggregator sites say she lost weight “without Ozempic” or “with no jabs”. We couldn’t trace these claims to a primary source, such as a dated broadcast interview or a quote from her own channels. Until there is one, the honest answer is that no verified statement from her has been confirmed either way.
This matters because GLP-1 medicines such as semaglutide are prescription treatments with specific eligibility criteria. Guessing whether a public figure uses them, in either direction, isn’t fair to them and doesn’t help you.
What we won’t report
- Before-and-after body comparisons or comments on her appearance
- Guesses about medical conditions she hasn’t disclosed
- Figures from sites that don’t cite where they came from
We take the same approach in our explainer on Sara Davies’s health and body-image claims, and in our look at how recycled “sad news” stories about Declan Donnelly keep circulating long after the facts have moved on.
Is the 1970s diet healthy? What authoritative sources say
We’re not going to review a TV programme’s diet plan. What we can do is set the headline figures against published NHS guidance.
The NHS says a safe, sustainable rate of weight loss for most adults is 0.5kg to 1kg (1lb to 2lb) a week. For scale, 5 stone is about 32kg:
- Over six months (the publisher’s figure), that averages roughly 1.2kg a week, slightly above the NHS range.
- Over three months (the magazine headline), it would average roughly 2.4kg a week, well above it.
This calculation isn’t a judgement of what she did. Starting weight, medical supervision and early water-weight changes all affect the numbers. But it does show why the three-versus-six-months gap matters, and why you shouldn’t treat a headline figure as a target.
The “eat like the 1970s” idea mostly comes down to familiar advice that the British Dietetic Association and the NHS Eatwell Guide already give: more home-cooked meals, less ultra-processed food and fewer snacks between meals. Those principles are well supported. A rigid diet built around a theme is a different matter, and that’s what your GP is there to help you weigh up.
Recovery and current work
Nothing in the public record suggests a health-related break from work. Josie Gibson has been a regular presenter on ITV’s This Morning and appeared on I’m A Celebrity… Get Me Out of Here! in 2023. Fronting the Channel 5 series in 2025–26 shows she is also working across channels.
TV schedules change quickly, so for her current role, check ITV’s and Channel 5’s own programme pages rather than fan sites. If you’re interested in the wider This Morning family, see our piece on Ruth Langsford’s career and earnings.

The bottom line
Here’s what’s confirmed. Josie Gibson has written a diet book whose publisher says she lost over 5 stone in six months. She also fronted a supervised Channel 5 experiment on eating like the 1970s. What isn’t confirmed: the three-month figure, the size 8 claim, and any statement about weight-loss jabs that we could trace to her directly. We’ll update this page if she or her broadcasters publish anything new.
FAQs
What has been publicly confirmed about Josie Gibson’s weight loss?
Her publisher, Pan Macmillan, says she lost over 5 stone in six months and went from a size 20 to a size 10, as described in her book The Josie Gibson Diet. Separately, Channel 5 confirmed she fronted The 1970s Diet, a supervised experiment with a diet designed by a doctor and a nutritionist. She has not publicly disclosed any medical diagnosis.
What is the 1970s diet Josie Gibson followed?
It was the basis of a Channel 5 TV experiment announced on 12 March 2025 and broadcast as The 1970s Diet: Could It Work for You? (listed for January 2026). A doctor and a nutritionist designed a plan based on how people ate in the 1970s, and she was monitored on weight, health and fitness. It is separate from the earlier weight loss described in her book.
Did Josie Gibson use Ozempic or weight-loss jabs?
Not confirmed. Some aggregator sites say she lost weight without jabs, but we could not trace this to a primary source such as a dated interview or her own channels. Until she addresses it directly, any claim in either direction should be treated as unverified.
How long did it take Josie Gibson to lose 5 stone?
The publisher says six months. Some magazine headlines say three months. The six-month figure has a named source, so we attribute it to the publisher. The three-month figure has not been confirmed by a primary source.
Is Josie Gibson currently working?
Yes. Nothing in the public record suggests a health-related break. She has presented on ITV’s This Morning and fronted Channel 5’s 1970s Diet series. Check ITV and Channel 5 programme pages for her current schedule.
Where can readers find authoritative weight and eating support?
Start with your GP. The NHS Weight Loss Plan app and the Eatwell Guide are free. The British Dietetic Association publishes fact sheets written by dietitians. For eating disorder support, contact Beat. Its helpline for England is 0808 801 0677.
