To not understand my weight?

I seriously don't get it.
I'm trying soooooo hard to lose weight.
It's bloody hard, hard work trying to shift it.
The eating less is easy, I find calorie restriction easy. I'm naturally a healthy eater and my diet consists of vegetables, salad, brown rice, potatoes, poultry, fish, a little red meat, lots of mixed beans and lentils. No cheese, cream, milk, ice cream, as I'm dairy free. I don't eat any UPF or takeaways or convenience food; everything I eat is home cooked from scratch. Nothing is fried. I've got Coeliac disease which means I can't eat gluten so that cuts out bread, rolls, pastries, cakes, biscuits, etc. as I medically can't eat those foods. No crisps, chocolate or fizzy drinks, don't like that stuff. I don't drink alcohol, I'm teetotal.
Anyway despite eating healthily I am overweight and I am now tracking my calorie intake on a diet tracker.
What's hard is not the calorie restriction, I'm doing that easily. It's how hard it is to get any weight off. AND how much my weight is bouncing around.
So here's my gripe about my weight:
6 weeks ago: 12.6
5 weeks ago: 12.8
4 weeks ago: 13.2
3 weeks ago: 12.7
2 weeks ago: 12.8
1 week ago: 12.6
Today: 12.9
WTF?
Throughout these weeks I have eaten EXACTLY the same amount of calories each day, 1,100. All weighed, measured and recorded in to my weight loss app. Not one day have I exceeded this amount of calories. Literally not once.
5ft 7.
45 years old.
And bloody fed up.
BTW I've had a load of blood tests done (not for weight loss but for other reasons), tested my thyroid, diabetes, LH FSH hormones, kidneys, liver, cholesterol, lots of other stuff I can't remember, and every test was in the normal range.
Why is my weight bouncing around all over the place????

I'm very similar height, weight and age to you.

If I calorie count generally, I can easily think I've eaten 800-1000 only.

But if I really think about it:
There was a glass of apple juice that I was offered at work. I had a biscuit around 2pm when they were offered round the office. I had a handful of nuts when I first got in home... and I realise that all those extra bits add up to a bit amount, and they're all sweet/fatty things. Because they're all small things that have less than 100 calories, I don't recall them offhand, but they add up quickly.
Is there any chance you're doing similar?

Tbf I'm a grazer. I'd happily graze all day rather than have full meals. I've been intending to properly diet and cut the snacking for about a year now. I can always find a reason why I need to begin tomorrow/next week/another time.

LindorDoubleChoc · 25/05/2026 11:58

I'm really curious as to how anyone eating 1100 calories per day can gain 10 pounds in 2 weeks. That's quite something.

Starvation mode isn't real

The body does adapt its metabolic rate, so although people like to trot out this out, it isn't factual.

It does yes, but weight loss continues as normal if a defecit remains. You need to remain in a defecit to lose weight. Again, there is no getting round this.

But calorie calculation is actually not an exact science at all. A pureed cooked apple is not the same as a whole apple. You will extract more of the calorific value from the former and less from the latter. Your body also regulates metabolism to adjust to calorie intake so will reduce RHR etc if you are in a sustained low cal diet. This is why calorie deficit diets plateau after a while.
There is good science now backing this up. So whilst the cals in<out is in principle true, you cannot actually override some of the biology that is going on to account for the basic cal requirement your body needs to function

All of that matters if OP is eating 1500 or 1600 calories and never moves a muscle, lives a completely sedentary lifestyle. What are you describing is marginal. It is splitting hairs and only comes int play when you have nailed basic calorie deficit. Over complicating simple rules is why people get stuck in a rut.

As I say, at 1200 calories, there is no way that OP is not losing weight. If she is not, it’s because she is eating more than 1200 calories and she is not in a deficit at all.

VintageLane · 25/05/2026 12:47

I’m taller than you OP. I would not lose weight on 1100 calories and I do loads of exercise. I’d also not lose if I was eating that many carbs.

PCOS has now been renamed PMOS - polyendocrine metabolic ovarian syndrome. This is to acknowledge that it's not a condition about ovaries, it's a whole body metabolic condition, and this does lead to the issues with weight you're experiencing. Mounjaro in my experience helps to reduce these metabolic issues, meaning eating in deficit results in weight loss.

there's quite a lot online about this change - eg https://www.verity-pcos.org.uk/pmos-media.html

If starvation mode really existed all the starving people in the world would be fat. They aren't.

I believe your body does get used to you eating less and slows down the use of calories, but at some point you must start losing weight again if you eat less food than you need for your lifestyle. I think estimates of calories in different foods may be highly inaccurate depending on many factors, fat content, nutrient content due to the life cycle of the individual animal or vegetable, if you are not losing weight eat less. If the op is finding it easy and not feeling hungry and not losing weight (even gaining) over a number of weeks they are eating well for their lifestyle no matter what the calories say.

HeavyHeidi · 25/05/2026 13:28

of course calorie deficit doesn't mean that there's a magical number and you will lose weight if you eat less than that. And yes people have different metabolism, and there are many things that affect it - I have thyroid disease and there's a huge difference in how much I can eat depeding on if I'm hyper or hypo. Calorie deficit means you need to eat less than you personally burn, and yes you will lose weight if you do that, we can't live on fresh air and sunlight.

You aren't eating enough!!! Your body is probably in starvation mode and desperately clinging onto fat. You need to eat more, eat more fat and get more active. You need to increase your metabolic rate not send it comatose with so few calories. Also your weight is not wildly fluctuating it looks pretty stable to me.

Starvation mode is a myth. Please don’t perpetuate it.

Silverbirchleaf · 25/05/2026 13:37

I could have written your post, with a few adjustments. Told myself at the beginning of the year, I was going to be a stone lighter now. I calorie counted, virtually cut out alcohol, cakes and threw out my lovely hot chocolate powder (contained sugar) I got for Christmas. Swopped to herbal tea.

people probably look at me and assume I spend the day eating cream cakes . I don’t.

I weigh 2lb more. I could cry. Actually, I have cried.

RoseField1 · 25/05/2026 09:54

Starvation mode isn't real. And how do you think she's going to gain muscle in that kind of calorie deficit?

I wasn’t suggesting she should exercise on those calories. If anything I was pointing out she needs to eat more.
But starvation mode does exist. An efficient body will convert food and store it. A very inefficient one won’t.
In a Western society that doesn’t need that sort of famine mode it becomes a nuisance and not a benefit.

There is a difference between sharing down an opinion and spreading misinformation.

Starvation mode has been scientifically proven to not be real. If OP eats more she will gain weight. Misinformation is harmful.

Sorry but I don't agree. I don't agree with your analysis and I don't agree that I should stop sharing my opinion. I have been alive long enough to know that where food and diet is concerned 'scientific evidence' changes all the time depending on who is funding the research and the latest fad of the day. I know there is an idea that science is somehow a pure and direct access to the 'truth' but that is simply not the case. Research is always funded by someone and it asks specific questions in specific ways. The food industry is as corrupt as the pharmaceutical industry. Sadly we have to make our own choices around food and diet because there is no one size fits all and because there is a lot of bad science.

As previous posters have said, if starvation mode was real anorexics wouldn't be able to get so thin and people in famines wouldn't starve to death. It's just impossible to live on less calories than your body needs to survive and maintain your body weight.

How can you disagree with a fact. Biology is biology. It’s fine you beleive the body can fuel itself with air. As oppposed to burning fat or muscle to fuel the defecit thus making your body lighter, And no one asked you to stop sharing that opinion, of course pointing out you’re factually incorrect is what many will do.

but if you wish to beleive the human body can fuel itself on air. Crack on.

First of all, someone did tell me to stop sharing my opinion and that is exactly what I took issue with. Second of all, where the fuck did I say the body can survive on air? Third of all, you have a tenuous grasp on what a fact is. I presented a theory not a fact.

No, they are not opinions. They are facts. Please explain how you think anorexics overcome starvation to get skeletally thin?

Sharing misinformation isn't just sharing a harmless opinion, ita sharing information that is not.true and will also harm people. If OP listens to the posters bleating on about starvation mode and eats more she will gain weight and be more upset than she already is.

Travelban · 25/05/2026 18:20

I had an operation in December and for the first time I managed to lose 4 kgs - I was unable to move for 2 months but I was really not hungry at all - didn't drink, barely ate and lost the weight. All the other times I have struggled to lose weight so I think calorie deficiency does work BUT:
I am active now and weight lifting and exercising and I feel like I need to fuel that bit more. I have a healthy appetite and even if I don't eat that much and exercise my weight is not shifting. So I think there is an element that when active and exercising, your body will demand nourishment too. And muscle weighs probably more than fat? Or so I am led to believe....
Either way something has shifted significantly for me as I used to be able to lose weight very very easily - not so much now!!

Well done you for both having access to the truth and being able to see into the future 👏👏👏 You must be the only person on the planet or perhaps you are God? And op is perfectly capable of taking on board or discounting any opinions expressed on this thread she doesn't need your protection. She already has a weight problem so she can try something new or keep doing what she's doing that isn't working - entirely up to her.

Then if you don’t beleive your body is fueling the defecit with fat or muscle exactly what do you think is fueling it?

the biology is undisputed other than by you. Eat in a defecit your body burns fat or muscle to make up the difference, when you burn fat or muscle it no longer exists. As such your body weighs less.

so you’re repeatedly posting about eating in a defecit and maintaning weight, according to your personal belief system. So explain how it’s fueling itself. As the only other thing we can see going in is air.

What on earth are you talking about. Are you quite ok. Are you now felling people that by eating more she won’t gain weight? How does that work.?
