To expect more than 0.5 pound weight loss?

I assume if you're on 15mg that you're lost quite a bit of weight before this plateau. If so, that's not that unusual. The body can have these periods where it is adjusting to it's new weight and will stall.
Realistically though, weight loss is just calories in calories out. So if you're not losing over a long period on 1200 calories then you're either eating more or that is too much for you.
I reached this situation myself. I was on 1200 calories, stopped losing. I personally can't manage on less than tha per day so I had to increase the amount of exercise I do. That was fairly easy for me as I was very lazy before lol.
I also agree with what some other people have said, some people don't need the average number of calories per day. My online calculated tdee is about right for me - a bit high but I've adjusted. But for some people it is wildly inaccurate. You have to adjust it yourself.

Do you have evidence for this? As anecdotally from the fhousands of social media posts I’ve seen this is far from correct and certainly wasn’t for myself.

I also have a blip once a month related to my cycle. Like clockwork - attaching my WL chart of the last month to illustrate…

I’ve been losing 2.5lbs a week on WLI - eating under 1000 cals a day mostly. No way could I do it without the jabs.
Tracking my calories, cutting out sugar and alcohol and focusing on protein at every meal has helped.
Yes it’s very low - but it’s the only thing that’s worked in 13 years.
Try cutting back to 1000 for a week op and see what happens?

I’m sorry OP, that must be so disheartening. It could be the recent gain is an anomaly due to time of the month or something but I think it’s nonsense for people to say 1200 calories is too much to lose weight when presumably you were eating more previously.

weigh daily as people say, hopefully the recent gain will have disappeared, but other than that I wonder have you been tested for thyroid issues or anything?

Weight fluctuates constantly throughout your cycle. It increases by anything up to 5lbs before your period for example and for some women prior to ovulation too. You didn’t gain 3lbs of fat in a week, it must be water weight. You retain whenever you drink alcohol too if this is something you do.

Are you exercising?

Eating less is not 'all there is to it'. Much better now would be to increase exercise given she is already on low calories.

If you are not losing weight but you want to, you need to eat less. That's all there is too it. You're eating too many calories.

I'm not saying you're counting calories wrong, you may be counting them perfectly, but it's too much.

A lot of people do not lose weight on "recommended weight loss calories", because it's too much for them to lose weight on. People don't like really admitting it or talking about it, because it's actually pretty bad for you nutrition-wise to eat little enough to lose weight (for those people).

Many people on the weight loss jabs who are suddenly losing weight when they couldn't before are losing it due to now being able to eat very little. Much less than you imagine. Again, won't be admitted, because it's terribly bad for you.

Well exactly

so perhaps you need to tailor your responses when you think you see a mistake

No need to be arsey, we all make mistakes.

Oops yes sorry !

It’s something that’s been happening a lot recently which is why I said the site.

Perhaps you didn’t read that post properly @Frenchfrychic

I'm on 12.5 and a slow loser. I realised over summer that any time I have alcohol it prevents me losing weight for that week. And agree with people about day to day fluctuation, I also gain around ovulation time and then it drops again about a week later - weighing every few days helps get a sense of what factors influence losing...

It’s not the site is it, it’s one person. They’re allowed to misread at 8am on a Monday morning.

Reread what I said… ‘your calories AREN'T LOW ENOUGH for loss’. Goodness me, the comprehension on this site baffles.

How long have you been taking it for and what was your starting weight?
and how much do you weigh now, what’s your BMI?

That’s what the poster you quoted said?

Are you still drinking alcohol during this period @Epicentre ?

Um that’s not how weight loss works, it’s the opposite, the lower the cals, the higher the loss. It really isn’t the more you eat the less you weigh.

I put on 3lbs whenever I ovulate- you need to weigh daily and look over months not days 😀

also I think until you have a few days of consistent weight at the 11st 3 you haven’t actually secured that weight loss- it can take a few weeks to stabilise.

this is without MJ but I’m assuming as you don’t weight much you’re on a low dose and wouldn’t be expecting rapid weight loss?

eta- I misread you were on 0.5mg 😱

What is your BMI? maybe your body is where it needs to be.

How are your energy levels? Do you need to eat a bit more and move a bit more? I'm on mounjaro and feel much better on a slightly lower dose when i can get a few more calories in, including carbs, which i couldn't on a higher dose, giving me the energy to exercise and enjoy life. It can be a fine balance.

How old are you? I do think as we get into our forties our metabolic rate can absolutely crash, and its terrifically hard to rebuild enough muscle to get it back when your hormones are working against you

Sounds like your calories aren’t low enough for weight loss then OP. How tall are you? You should have lost a lot more than that on such a high dose.
