Jabs to lose 1.5 stone?

torquayturkey · 02/08/2026 12:45

I’m 5’7 and feel my best when I’m between 10.5-11st. A couple of years ago I had a really bad time with my mental health (ended up sectioned) and lost 3 stone, making me 9st and I looked too thin. I’m much better now and I’ve gained 3st - I’m now 12st 4 and feel disgusting.

is it worth trying a GLP-1 to lost the 1-2 stone? I’m mainly worried about the side effects eg vomiting and stomach pains. What is everyone’s experience? Thank you.

This comment. You shouldn’t feel disgusting about being very slightly overweight.

Very slightly overweight? She has every right to feel what she feels. Im her height and at 11 stone I hate the extra weight I am carrying! I feel so uncomfortable. Stop projecting!

yeah I just get frustrated that people think that taking the jabs means someone doesn’t have to change their eating habits…because it isn’t true at all.

I eat 850-1000cals a day, I meticulously weigh everything I eat, if I see friends and family and they’re drinking etc I still choose not to. I still have to say no to things I would absolutely like to eat, the jab just makes it so I’m not hangry, so that when I make the right choices my resolve is not broken so easily. And I do it whilst feeling sick for 3 days of the week.

Ive lost 3st in less than 3 months because I am taking it seriously and I am putting in the work. And people act like the jab makes it so easy it can’t possibly fail…but that’s not true.

But it does make it easy, would you be able to reduce your calories that much so consistently without the jabs? I mean you technically could, but I bet it would be much mentally harder. Or we’d all be doing it already and saving £200 a month to boot. I personally don’t get offended by people saying I’m taking the easy route, you’re damn right I am, because why wouldn’t I!

p.s agree with others, that’s an unnecessary calorie shortage, I assume you’re planning on staying on the jabs to be looking to lose that dramatically that fast and have any hope of keeping it off.

@lindanovak are you a doctor?

Do i need to be?

Theworldsgonemadagain · 02/08/2026 17:29

Op you can do it without these jabs. Do you currently excersize? That would really help your mental health so it's a win win. Start the couch to 5k. In my opinion these jabs should only be for seriously obese people not just to loose a few lb. I would also worry about side effects.

lindanovak · 02/08/2026 17:16

You are not eating enough calories to fuel your body properly and that rapid weight loss isn’t something to be pleased about.

oh no…time for me to rethink my entire life choices now that Linda thinks I should eat more.

Thank you SO MUCH for educating me on what is an appropriate amount of calories to eat and weight to lose.

FWIW you can actually do an 800 calorie diet for 12 weeks without causing any damage to your body and healthcare professionals can recommend this to some people with high levels of obesity and health issues in order to rapidly correct these.

And with regard to the amount of weight loss that is healthy/unhealthy…The basic recommendation for weight loss calorie counts currently on the jabs is 1400. For someone who is very obese that means that can mean a daily deficit of 1500 calories on a sedentary lifestyle. Add into this a small about of exercise - a reasonable walk can do 250 calories, and you are at a deficit of 1750, which is 3.5lbs of fat per week.

12lbs for first 2 weeks whilst your body dumps all of the water weight, Glycogen, extra waste in your digestive system, leaves 10 weeks (since I’m on 12 weeks so far) - 3.5lbs a week for those 10 is 35, plus the 12 is 47lbs which is more than I’ve lost.

So yeah, tell me again how that weight loss is too rapid when I’ve lost 42 but could have lost more based on the calorie deficits that are recommended by pharmacies and medical professionals?

It is easier, but it is not easy. All I’m saying is you have to make the right choices still, you still have to have significant side effects (or I do), you still have to refuse to eat and drink at events that you used to enjoy.

I’m referring to the people who think you jab them don’t make changes and the weight just melts off, it doesn’t. You make the effort, you put in the work, you just don’t have to feel starving while you do it.

If you don't have a related health condition then you won't get Mounjaro at BMI 27. I started at BMI 29 as I have PCOS. I went back onto 2.5mg recently to try to get to 10.5/11 stone as my weight has crept up slightly again.

AnotherPidgey · 02/08/2026 17:35

I'm using Wegovy to come down from a peak of BMI 27 and in 5 weeks have got it down to 25.5 so far.

I'm one of those lazy-arsed layabouts who runs half marathons, lifts weights and was trying to make wise, nutririous choices such as half my plate being salad to moderate my portion sizes, but while my appetite hadn't changed in recent years, my metabolism had. Any type of hiccup, Christmas, holiday, injury (plus 2020-21) and it creeps up and I've managed to maintain and work a little off, but not get a notable net loss.

I was reaching the point of either spending on WLI or replacing my wardrobe.

I'm short, I don't carry it well. As I was getting heavier, running was getting harder, slower and more niggly.

What Wegovy has done is dial my appetite down so I can feel comfortable on the lower calorie intake that my body needs, because it's bloody miserable trying to eat half of the rest of your family and still feel hungry and light headed. With WLI, I feel more connected with genuine physical hunger and less distracting emotional "hunger".

I haven't had to make major changes because my framework was already decent, it just manages the curveballs better.

Do i need to be?

Without knowing anything about the posters health, you have no way of knowing if what she is doing is right for her.
Very low calorie diets aren't recommended for the majority of people, of course. But if someone has say, a life shortening weight related health condition they would be. Or if they have a very low TDEE due to a being immobile, eg due to disability. Or if they are starting from a very high BMI.

Just because something isn't right for you doesn't mean it applies to the next person. Its very arrogant to decide you know best and can give medical advice just because you've lost a few pounds.

Yes you will, just not from your GP. Private prescription is fine

3 stone in less than 3 months and you think that not rapid based on ‘it can be faster’? Ok. I mean you do you and all that but let’s not pretend your approach is at all healthy.

That's the case for many providers but not all, in the UK at least - some will prescribe to BMI 25 with no health conditions, and others will allow micro dosing at a lower starting BMI, eg Healand. They do tend to be the providers that are more expensive (albeit tends to come with more support)

I think you just need to look at the monthly threads on here or Reddit to know that’s highly unusual and certainly was not my experience, I’ve had no side effects, neither does my husband, like 80 percent of people.

so either you made that up, don’t really know anyone on it, or have an unusual cluster of reactions in your friendship group,

My friend is the same, sick a lot, esp if she accidentally eats something she shouldn't like greasy food or drinks the wrong thing like pineapple juice. I expect all people have different reactions. My other friend is fine on them but says the first couple of days after the jab she can't eat certain things or will be sick. Sickness is listed as a common side effect.

Even the private guidelines say for weight loss you must have an additional co-morbidity requirement to be prescribed Mounjaro in the first instance with a BMI of 27-29.9. <27 You can't start on it at all, but you can restart if you've already had it.

I'd love to see the study that backs up this claim. The NHS recommends a deficit of around 600 and eating in a deficit of 1500+ is going to cause loss of muscle and bone density, as well as increase the risk of gallstones and hair loss. This kind of deficit falls under a VLCD and shouldn't be done for longer than 12 weeks.

Boreded · 02/08/2026 17:43

RoseField1 · 02/08/2026 17:32

Why are you eating so little and trying to lose so quickly?

I’m eating so little because I’m not hungry, and I’m losing so quickly because I’m not eating much, and I’m fat.

I’m not trying to ‘lose so quickly’ - I eat at mealtimes, and I am NEVER hungry so all I am doing is eating a balanced meal and stopping when I’m full. As a result the weight is coming off.

If I pushed myself to eat when I was full then I’m setting myself up for more problems because I’m not learning not to overeat.

I’ll be upping my calories in the coming weeks because I listen to my body. I’ll be going to Florida and absolutely pounding the pavement in awful heat so I will need to build up better stores in my body and be better hydrated too…I adjust sensibly to match what I’m doing.

This is quite worrying. With kindness why would you continue to take something that makes you feel like shit when a healthy diet and exercise would make you feel good.

Because I do not lose a single ounce without the jag. Not one.
MJ is the ONLY thing that has got any weight off me for about 13 years.
Nothing works.
If I’m feeling sick & no appetite then I’m not driven to compulsive eating, feeing starving all the time and following yet another diet that doesn’t work.

My old lady MOT is showing my bloods normalising, hypertension resolving, mobility and breathing improving.
My health is improving which is worth every day of crappiness.

Backpedaling with pendantry isn't a good look. You implied you know better than them and their prescriber. And you have no way of knowing whether those calories are safe for that poster, or whether rapid weight loss is advisable for them. Again, just because rapid weight loss isn't a good thing for you doesn't mean that applies to everyone. Try thinking outside of your own perspective for a second.
