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?

How much are you lifting

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.

I’m doing both gym and jabs!

Working out always adds water weight to me temporarily, because muscles need it to repair. Also blood volume gets heavier. You are doing your body so much good, the results will reveal themselves once the fat is lost!

DitzyDerbyBabe86 · 25/01/2026 20:16

Gym 100%. WLJ come with a slew of health drawbacks. Numerous people I work with are on them and I could count numerous who now have health issues. The gym will be doing your body the world of good.

Because the battle if the bulge is won in the kitchen, not the gym. And don’t fall into the ‘you’re building muscle’ crap - it takes a very long time and significant work to build muscle. You can tone for sure, but build? Not in a month.
Work out your TDEE, minus 500 calories, ignore anything burned during exercise, and be consistent.

The two things aren't mutually exclusive. I'm on WLI and I also up my protein, go to the gym 4 times a week and lift weights and do everything you do.

You need to do you, never mind what your mates and husband are doing. It's not a race to see who can lose weight the quickest. Two stone to lose really isn't all that much, perhaps the people losing quicker have a lot more to lose.

By losing weight slower and building muscle you will be in a better place than those losing weight quickly and not thinking about exercise and nutrition, regardless of the method used to lose weight

How much are you lifting

ChangeTheDayJob · 25/01/2026 20:06

Honestly, well done you for taking action!

Muscle and fat weigh the same. You are definitely putting on muscle if you're lifting.

Try to shift from the scales to looking at what you see in the mirror and how your clothes are fitting.

Drink plenty of water and bear in mind your body will retain water when you eat food high in salt and through your menstral cycle.

If you must weigh on the scales, do it every day and make a note of it. Do at the same time every day (preferably in the morning before eating or drinking anything). Eventually you will see your body's natural fluctuations.

Remember, when you weigh, you're weighing your whole body - not just fat.

Are you dull?

This is not true for everyone. I gain muscle super easily. My first year of lifting in 2019, I had complete recomposition went a size down with no change in my weight while eating at 300 deficit. It is obvious in my pictures. My coach at the time was in disbelief. I am dense, which is not uncommon for women from my part of the glove

i appreciate what you say may be true in general but my personal experience is different and I have read plenty of literature to support it.

i miss those days.

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

Allaboutthecats · 25/01/2026 08:25

3 lbs is great for a month. You'll be gaining muscle mass. Take measurements too.

No. Extremely had for women to build muscle.

Op - what you see on the scales is just your mass.
As long as you are tracking calories than you will be fine

I'm quite a few stones overweight and have decided this is the year that will change. I have looked in to weight loss jabs and have been reading in to it and contemplating over the last 18 months. What I've read has made me come to the conclusion that losing the weight without medication sounds much more sustainable. The biggest thing for me is the concern that you need to stay on them for life or you risk piling it back on and that just isn't for me or my bank balance. So I've started eating better and doing more exercise. It may be slower but in my opinion the risks with the jabs just dont add up for me.

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

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.

Elishiva · 25/01/2026 18:11

I stopped drinking on New Year’s Day, started going to the gym 2 weeks ago.
Ive also got 2 stone to lose, I’m only 5”1 so am only a few pounds off being obese.
Ive lost 4lb so far, I’m aiming for a 1lb a week, slow and steady wins the race.
it’s taken me years to put all this fat on so it’s not reasonable to expect it to drop off fast with a relatively small amount to lose and a low calorie allowance, I’m looking forward to being slim again but I also want to be healthy.
Keep going op, as others have said also take your measurements and some photos.

Jackiepumpkinhead · 25/01/2026 18:09

You could do both, I do.

MightyGoldBear · 25/01/2026 18:08

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.

This is a great post and representative of the value of decent workouts and nutrition. And of the fact its only fat loss, not total body weight, that's really important.

In the longer term, muscle really makes your metabolism faster and more likely to use calories to feed muscle, not store extra fat, while leptin levels are really managed a lot better if you exercise regularly meaning you're more likely to keep appetite and snacking under control. Your blood sugar and insulin response is also more effective under these conditions. Its all part of how good diet plus exercise equals more likelihood of losing weight permanently.

Jabs make you lose weight faster but thats also because it does way less of all the sophisticated other benefits that exercise plus good diet does (thats why the second is slower but overall more likely to benefit you).

No judgement from me of what people choose for their individual situation and choice, though.

Is this why the gladiators all eat like 5000 calories per day? I don’t really understand this

Yes basically, but also they work out a huge amount so need it to fuel themselves.

ThisIsAGlobalPlayerOriginalPodcast · 25/01/2026 17:31

Wickedlittledancer · 25/01/2026 11:52

It’s really not muscle gain,it’s virtually impossible to gain muscle when in a calorie deficit.

Read my next post. It is easier mentally as it stops the food noise and you can focus on the training and the lifestyle change. I repeatedly did say that If I had the option I would have had them myself.

so may I ask why are you attacking me and making personal remarks??? You do not know me. I have supported OP choice and expressed shared frustration.

I'm not attacking you, I'm responding to a comment. This is how these forums work.

I have been doing calorie deficiti, upping protein and doing strength training. I've only "lost" 2lbs but my body has completely changed shape and my scales say I've lost a stone of fat and gained nearly a stone of muscle. Gone from 34% body fat to 22%. If it was based on weight only I would be disappointed with 2 lbs!

It's not the easy way at all, you still have to put the work in (they don't melt fat) and even if it is, so what? Why do people want to martyr themselves thinking, I'll do it the natural and most difficult way. I have trained hard, eaten well and the jabs helped. I'm keeping the weight off by continuing as I did on the jabs.
