I started down the gym a week before Christmas. Cut alcohol first of jan and been dieting and upping protein. Been going gym 4 times a week. Started weight training and lifting weights. Was feeling good this morning. Weighed in and ive lost 3lbs. Im a couple of stones overweight.

Im really demoralised. All my mates have lost loads of weight on ghe jabs. Im just wondering if im doing the right thing now. Aibu?

I lost my first baby weight using willpower and calorie deficit. Took 4 months to lose 3 stone (20kg).

This time I’m using mounjaro to lose 3 stone and I think it will take the same time. This time is easy though. It’s magic and absolutely no willpower needed on the diet front 😂 Still need to exercise though to preserve muscle. I found a pharmacy that accepted BMI 27 and perimenopause as a reason.

For that group, it's about rarity and relative value. If they used to be above 90% of the population in their personal rankings but all of a sudden an extra 20% move up to the same level and some of them even move higher, that means fewer people they can feel superior to. Figures made up to illustrate point, but hopefully you see what I mean.

I get you but it’s just so funny, who thinks in personal rankings!

HattiesBag · 27/01/2026 19:26

But you're gaining cardiovascular fitness and strength.
A number on the scales is just one part of the puzzle.
Are you getting 30g+ of fibre a day?

I just don’t understand their mindset at all. Why would their worth be affected? They are still slim, still get the benefits of that.

There's a lot of concern trolling on here about MJ. I only realised after starting the jabs and engaging in online discussion how many people have thinness ranking systems, and don't want their own positions relative to others to change.

Skip breakfast. Intermittent fasting. I’m skinny and realised when reviewing a students paper (academic) that that’s the reason I’m not fat. What time to you go to the gym.

I rarely eat anything before 11:30 or after 7pm and have been overweight for about 25 years.

I did both despite being in the “you don’t need jabs if you’ve only got 2 stone to lose” catagory. Had an awful 18 months where Covid triggered recurrence of my childhood asthma, which took ages to get under control and interpurptes by exercise routine then I had to have significant surgery which took me out for months and then just when I was getting back to it I broke my leg. This plus perimenopause onset and I gained 18kg over this period. Trying to lose just felt insurmountable especially as I’d gone from pretty fit to barely able to heave myself up the hill from the station and all my joints hurt. It’s taken me six months to lose the weight but best part was from first week of the injections the joint pain subsided so I’ve consistently made 4x a week gym, often 5. Am mixing heavy weights, spinning for cardio body pump because I just like it and reformer for flexibility and balance.So nice feeling strong and fit again but I will also stay on low dose wli for a further year until my body gets back used to this weight level and I embed the fitness changes. Another vote for “Both” , if affordable

Its so bizarre how 'concerned' they are about an overweight person now being a healthy weight. I totally understand feeling a genuine envy of someone losing weight when you have tried and haven't (i felt it) but I was always pleased for them just annoyed I wasnt managing it.

This 100%. Someone made a really rude comment about my weight loss on here, had the nerve to say how worrying it was (dont know them at all). I have been on the jabs since 1st November. Had 3 stone to lose, have lost 31lb since then but that is actually only 2.4lb a week but if you take off the 9/10lb I lost in the first week it is under 2lb a week. Its just consistant every week which obviously is so hard doing it alone when life events etc get in the way. I haven't lost over 2lb in a week for a while so its definitely a healthy weight loss.

jabs didn't make me lose faster. They made me lose longer, that's the difference. If you are struggling with food noise and addiction, yes you can get your willpower together and restrict food, but it's exhausting and most people fall off the wagon rather sooner than later, usually before they have achieved their desired weight loss. Another failed diet.

Me too, I couldn’t keep it up, not every days for months and months. And then live like that in maintenance, I was insulin resistant with sleep apnea and high cortisol, it was an impossible task to get myself out of it; when your exhausted and constantly craving foods and feeling starving hungry. Mj let me lose consistently and for the length of time needed.

at 1.5 lbs a week, it was not fast, it was healthy weight loss, but it was sustained over the amount of time it took me to lose over 6 stone.

narcASD · 27/01/2026 00:08

I do both, 3st one lost in just over 3 months, I have no side effects from Mounjaro, no sickness or reflux, just a better attitude towards food and less cravings, I started the gym just before Christmas and can now really start to see the benefits. Take measurements too as scales are just one way of measuring.

GLP affects insulin so it does make you lose weight faster. It curbs hunger reducing calories but it also how these are broken down and metabolism. You are misinformed.

Additionally for people who are new to weight training, muscle gain DOES happen in caloric deficit. It is called recomposition where your muscles draw what they need from the stored fat. Hence muscle gain and fat loss occur simultaneously and is VERY common in the first year of training. It gets harder down the line due to how muscles expand.

you need to inform yourself on how biology works

It isn’t faster nor does rhe manufacturers claim rhis, in fact they advise 1-2lbs a week and how to eat. But do link to showing us how they make us loose weight faster.

You've completely misunderstood what I said, but thanks to another poster upthread for correcting you on my comments.

I have a masters degree in exercise science with a dissertation specialising in the biological antecedents of fat loss so 'having a quick google' as you suggested isn't something I'd do - I only use quality research studies and googling doesn't cut it if you're really serious about interventions that work.

How did I misunderstand your statement, you said, quote unquote Jabs make you lose weight faster

they do not. And irrelevant of your degree in exercising,, that does not in any way relate to scientific knowledge of the meds. They do not make you lose weight faster, there is no way round this and I corrected it.

Don’t be ridiculous!! Your genetics and family genes will be why you are the way you are! Cutting essential meals out messes with your sugar levels and also makes your body hold onto every calorie as it’s put into starvation mode! Telling someone some utter drivel when you clearly have no medical experience or knowledge severe stupid

Research intermittent fasting. It doesn’t mess with the sugar levels in a bad way but rather gives the body a chance to reset. It’s been proven to reverse type 2 diabetes. And as for “medical experience or knowledge”, I’d suggest that nutrition and diet are an area where modern medicine is woefully behind/ plain wrong.

Wickedlittledancer · 25/01/2026 17:38

This is utter nonsense. The medication doesn’t make you lose weight faster, how can you be wading in and so ill informed; your rate of weight loss is fully dependent on how many cals you consume. And a good diet and exercise is not mutually exclusive to the injections, in fact for many of us they go hand in hand.

please take some time to at least spend some cursory mins googling and learning the basics on the meds.

If you lose 3lbs in 3 weeks that’s very good!!! Slowly us far best as then it stays off!!! Losing a stone in a month is far far too much too quickly and as soon as they stop the injections they will pile it all and more back on!! Also you will end up with lots of loose skin if you lose weight quickly whereas slowly it shrinks with you

The simplest easiest way I've lost weight and relatively quickly nearly a stone in a month. Intermittent fasting 16/18 hours and last 2 weeks ive added a keto diet but even that is super simple not strict or calorie counting.

That's without really adding in exercising I do walk daily and cycle but nothing major. Its all about eating less and what I am eating is high in fat and protein so I'm fuller for longer. Its been such a game changer and something I can see myself keeping up even when I add in treats. Mentally it's so simple to say to myself I eat between 10am and then stop at 6pm. Many days I'm not even hungry till 1pm. And I really do love my food so quite the change for me.

Hi, if you don't mind me asking what's ur start weight to have lost 1st in a month?

I was on the jabs. Put on in region of 6kg. Looking at keto.

Would like to do intermittent fasting but no idea how I work that when working n/s

How much are you lifting... Give examples

Why are you asking? If you clarify I can try and answer in a helpful way

whitesilvered · 25/01/2026 20:42

PurpleCoo · 25/01/2026 20:31

I'm not sure what you are hoping for by asking me that.

It's different weights depending on whether I am doing biceps, triceps, chest or shoulders etc.

If I said what I lift for each area, I am not sure how helpful that would be for anyone else, as it's very individual. I started low though and increase once it gets easy to lift that weight. I have been doing it for over 6 months now I reckon.

Where is the muscle? You lose body fat, where is the muscle?

it's usually under the fat, or what do you mean?

You’ll have to eat better and exercise forever to maintain your weightloss either way. Good luck to you! 🙌
