Hi,

I've been on my weightloss journey for some time. Lost 3 stone through diet and exercise and really struggled to lose more.

I put some weight on, struggled with cravings so decided to try mounjaro.

I'm 5 pens in, just ordered my 6th and upped the dose to 10mg and only lost 1st 8lbs in that time. That's from beginning November, (with a big loss in my first week of mounjaro).

What am I doing wrong ? I eat in region of 1200 calories a day. I try to exercise but not as much due to time.
I'm only grateful that at least the weights not going back on. I have the odd treat but I count everything.

Any ideas/ tips /advice ?

If your maintenance is really that low, which seems incredibly unlikely unless you’re both very short and totally sedentary, then the 500 calories deficit isn’t suitable for you. Please speak to a GP.

Thanks but you have no idea.

I think I will stick to my endocrinologists advice rather than a random internet mum.

Most doctors advise a loss of 1 to two pounds a week is safe. No idea why you think otherwise…

Maybe look at your calories? If I ate 1,200 I wouldn’t lose weight.

if you're obese then this is literally not possible to be true

FortyElephants · 21/03/2025 18:10

Misread the OP.

InfoSecInTheCity · 21/03/2025 18:10

Your TdEE calculation puts maintenance at 1899 calories, so a deficit of 500 is 1399. You do not need to eat less calories than you already are.

If you have some kind of medical issue that means you genuinely only burn 1300 calories a day to maintain an obese body weight then you are an extreme outlier and should not be posting things like this on a public forum.

There’s no way a qualified endocrinologist has said that 2-3 packs of noodles and a couple of coffees a day is adequate nutrition. If they have then they should have their medical licence revoked. Missing pretty much all the food groups.

namechanged4goodreason · 21/03/2025 17:35

I live on noddles about 2-3 day and coffee.
I dont think i cover a 1000 calories.

This is eating disorder behaviour. Don't post on public fora please, it's extremely irresponsible.

I don’t eat noodles or drink coffee.

And I’m not obese. I am now overweight 😍

MsBucket · 21/03/2025 18:18

Nowvoyager99 · 21/03/2025 17:38

I maintain on 1300. So 800 is the recommended 500 below maintenance that allows me to lose between one and two pounds a week.

@Nowvoyager99 This might be something that your endocrinologist might have recommended, but please do not try to give dangerous and unhealthy weight loss advice to someone online or even IRL. I do find it in interesting how you mentioned your endocrinologist only later. This might work for you in consultation with your endocrinologist, this doesn’t necessarily mean it’s safe to do so for everyone else without a qualified HCP.

Why do you find this so funny @Nowvoyager99 ? Do you think encouraging other people to eat anorexia level amounts relative to their body weight is funny?

Nowvoyager99 · 21/03/2025 18:20

I genuinely don’t understand why wanting to lose weight at one to two pounds a week, which is what OP appears to desire, is being seen as “dangerous”

If she’s not losing that on her current intake, she needs to reduce.

Fast 800 diet obviously passed some of you by too…

Because going below 1200 calories more or less is starvation levels! It's going to lead to physical health problems. If your TDEE is too low then you physically can't lose 2lbs a week because you'll be reducing your calories too far. The body needs calories to function. You'd think if you were under supervision of an endocrinologist who knows how little you're eating you might have discussed the risks of eating so low?

Just because the fast 800 diet exists, doesn't mean it's a good idea!

You have a problem. It's not an endocrinologist you need to speak to.

Wanting to lose a pound a week is not the same thing as encouraging someone to have an unhealthy calorie deficit. 800 calories for someone with an active lifestyle is not healthy. You may have an endocrinologist, this does not necessarily mean this works for everyone else. It’s not a one size fits all.

InfoSecInTheCity · 21/03/2025 18:33

Fast 800 is a short term plan designed to last no more than 12 weeks because it’s not sustainable. The idea of it is to do intermittent fasting, low carb and low calorie, designed for people who are significantly overweight to kickstart weight loss with the goal of putting diabetes and pre-diabetes into remission. It’s not recommended as a long term sustainable way of eating.

Strudie · 21/03/2025 18:44

Honestly I’m really hoping that the two posters on here pushing a long-term very low calorie approach, apparently on ‘medical advice’ (yeah, right) are just wind up merchants.

OP, I’m a slow loser too and it does get me down sometimes, I’m averaging 0.5lbs to 1lb a week. It’s all going in the right direction though and I’m prioritising making sustainable changes and good nutrition over rapid loss. I could maybe manage on under 1000 calories now with the suppression, but there’s no way I’d keep it up after coming off the injections, and it could cause other issues such as muscle loss, hair loss etc.

Mounjaropen · 21/03/2025 18:45

@Hundredthmillionthdiet come over to the Mounjaro November ‘24 starters thread. We’re at the same point as you. Lot of support, encouragement, ideas for recipes etc. Not everyone loses at the same rate.

I think you probably aren’t eating enough protein from your description and it’s possible your body has adapted to your low calorie diet (look at Metabolic adaptation). You need to keep your body guessing a bit by varying diet, exercise etc. You do need to keep an eye on macros and ideally have 1-2g of protein per Kg of body weight per day to ensure that you don’t lose too much muscle mass.

Finallydoingit24 · 21/03/2025 20:58

Nowvoyager99 · 21/03/2025 16:38

I would hardly lose anything if I consumed 1200 a day.

I usually eat around 800 since starting MJ.

If you aren’t getting adequate suppression maybe go up to max dosage, but I suspect you are just consuming too many calories to make significant loss possible.

Wtf

Sampler · 21/03/2025 21:44

I’m a slow loser too op, but I’m fine with it. The main thing is to not panic and not rush. 1lb a week is fine, sustainable and healthy. You aren’t exercising much atm and I’m assuming you are eating healthily - so keep continuing on and it will come off in the end. It’s not a race although some people seem to think it is.

PersonalBest · 21/03/2025 21:58

SilenceInside · 21/03/2025 16:04

So, around 20 weeks and a 22 pound loss, is that right? That gives an average of 1.1 pounds lost per week, which is an expected amount of weight loss.

1200 calories puts you at about 500 cals below your TDEE roughly, per week. Which would be around a pound a week weight loss, on average, which is where you are at. So I would say you're not doing anything wrong at all.

This seems right? Losing weight is hard and it is a slow process

NewbieMJ · 21/03/2025 22:28

Dismayed to see such unhealthy "advice" on here about extremely low calorie intake, but glad too that it is countered by sensible posts.

I would say 1200 is too low and you are at risk of malnourishment.

Always be mindful of coming off/reducing MJ when you get to your desired weight loss goal. Your way of eating has to be sustainable long term. It is simply not possible to sustain an under 1000 calorie daily intake in the longer term (unless you enter disordered eating territory which we all have a responsibility to avoid promoting on these forums. It is bloody dangerous).

I have a lot to lose (3.5 stone down) and am a relatively slow loser and am not a super responder to MJ. It's worked out half a stone/7 lbs a month).

The key to this journey, in my opinion, is to sustain weight loss. The only way to do that is start as you mean to go on. Adopt a nutritionally dense way of eating that becomes a way of life.

Malnourishment is frightening. As others have mentioned - hair loss, muscle loss and the likes. Look up "set point". Dr Jason Fung is excellent in making sense of obesity and helpfully gives some good perspective on our calorie intake.

It's disheartening, as you say, seeing the scales go down slowly, but you've done great and it is coming off.

iamnotalemon · 21/03/2025 22:41

I think that’s great to be honest. I know some people lose weight by looking at a salad but you shouldn’t compare yourself. The weight will come off and clearly has - sounds like you’ve lost a lot of weight anyway before the WLI. Well done
