To not understand my weight?

I think 1100 calories a day may be too low

It really isn’t.

As a professional dieter I’m similar height but ten yrs older I can only add I have similar health issues (PCOS) and here’s my advice. Add cals up to 1400 a day. Expect one pound a week loss could be two one week none the next. Be patient it’s a long game. Weigh and track everything! Key things that will affect you is high cal items so olive oil peanut butter honey etc weigh on digital scales and be like a ninja!

I track on free app my fitness pal. I added a little extra exercise each day like exercise bike or twenty minute walk.
Doing this I lost fifty pounds in six months . Good luck.

people will say it's a case of calories in, calories out but I am exactly the same as you at 44. I eat lean protein and veg twice a day and my weight just doesn't budge. it's immensely frustrating! I had success with hbd a couple of years ago and am going to try and go back on that strictly after half term.

I believe you because the same thing has happened to me.

In the end, I threw away the scales (well, put them in a place that wasn't easily accessible to me!) and bought a button through dress (Rua Style from White Stuff) in one size below my usual size.

I try this on every two weeks. It's a good way to see if you are changing without the scales.

How much and what do you drink?

I am on Mounjaro and eat 1200-1300cal a day, that's apprx a deficit of 500. But I only loose significantly if I drink at least 3l of water and herbal/lemon and ginger tea. Black tea is extra and cappuchinos or latte have to fit in my daily count.

No fizzy drink, hardly any juice, no squash.

Are you sure your scales are working OK?

Completely agree with this but she is still 0.3 heavier than 6 weeks ago.

Read burn by Herman Pontzer.

And try and increase your muscle mass like previous posters have said!

What’s carb heavy? Did you skim read and see all the things she COULDN'T eat…?

That's not enough calories. Are you feeling really lethargic on that? Upping the calories and increasing exercise might be the best way to go. Drink lots of water, it could be water retention causing the fluctuations.

I was exactly like you, pretty much same weight as well. Recording everything, 1000-1200 kcal, working out - and nothing.
I am now slim. I achieved this by mounjaro and using and AI app to photograph everything, all drinks, all snacks and random nibbles included.
Most people underestimate their calorie consumption, many studies on that topic. In a study of 10 obese subjects who reported diet resistance, 100% underestimated their caloric intake by an average of 47%. Another study- all participants underestimated calorie consumption, with overweight individuals underestimating by 40%.
And yes, as it turned out, even as a lifelong calorie counter, my estimates were wildly off. Even when measuring the main ingredients, it's quite amazing how little things add up. So something I would have recorded as 300 kcal, the AI estimated as 700. And when I looked at the breakdown, I had to agree 700 was probably more accurate. So I didn't lose weight when I thought I was eating 1200 kcal. I did, when I was actually eating 1200 kcal.

A lot of this will be water. There are quite a few calories in legumes, and I'm not sure I trust a lot of these apps. Have you looked at packets and worked out what you are getting calorie wise? That isnt a lot for someone taller than I am, if I could stick to 1100 I would lose weight I'm sure with only activity from my job and not much more at the moment. Generally it's 4000 calories a pound in or out, but everyone metabolises foods differently apparently. If you are exercising at all, muscle is significantly heavier by volume than fat. I think as some have said you need more fat and protein to fill you up though clearly you sound as if you are happy with your current intake. Personally I am wary of beans as a means to protein though obviously good for fibre and micronutrients. Also dairy free here.
Edited to add, have you weighed out a pound of something? It really isnt that much yet we stress over them in unison I guess!

I found this too and I have come to the conclusion that it is my metabolism slowing down a lot. So my advice would be to look at things that increase your metabolism. The single most effective one at our age is weight lifting. I am 5 weeks in and still haven't shifted any eeight but I am starting to look slimmer because far is becoming muscle and eventually I hope it will start to shift..

Good luck though I know how frustrating it is.

The only way I can lose weight nowadays is to cut out carbs. Nothing else will shift the weight. I found it quite easy to carb cut once I was in the right frame of mind, but it does taking planning because it’s not just bread and cake.

Even lower calorie foods will have an impact of you eat too much. You need to reduce calorie intake and or increase exercise. Weigh yourself once a week.

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.

Have you measured your fasting glucose and insulin along with your HbA1c?

If not, I’d check these as a priority but you may have to go private for the insulin unless you can convince your GP. You can buy a HOMA IR test online which will assess if you’re insulin resistant. Many people are but have no idea as docs only get concerned once a person becomes diabetic.

I would also buy a little blood glucose monitor to see what that’s doing 1,2,3 hours post eating with different foods. You might be surprised what certain ‘healthy’ foods can do to blood sugar.

1100 is a bad calorie intake for me. I do not lose weight at that level, I either have to go a lot lower which is unsustainable or go higher. I find 1800 works for me but I have an active job. At 1100 my body goes into starvation mode and holds onto as much as possible, I end up lethargic and unproductive.

You need to do strength training alongside it. Lifting weights increase your metabolism

Fellow coeliac here, and exactly the same problem. I’m convinced it is a coeliac thing but nobody believes me and is interested in finding a solution. I find my body just “fights” me daily - an inflammation response? Add in menopause and I literally feel likes there’s no hope in shifting any weight - it just fluctuates like yours and slowly creeps up. If I cut amounts down, I feel like my body goes into fight or flight mode and just stores everything.

If OP didn't get out of bed all day, she should be on 350 kcal/day deficit on that diet, so should have lost a fair bit by now.

Write down on here what you ate today since midnight, and every thing that passes your lips, OP, all fluids and all food today. Somewhere is 600/day missing kcal, I'd wager.

It looks like you're at maintenance with a water weight gain every 4 weeks due to your cycle

Don't weigh yourself everyday
Drink lots of water like 3l a day
Be mindful of hormonal fluctuations the scales only tell part of the story
Get your thyroid checked

Apart from the 13.2, which could be a scales anomaly, all the other measurements are effectively the same when you account for variables that have nothing to do with how much fat there is in your body, which is what you're trying to lose.

However, as someone who’s the same height and weight and slightly older than you, I don’t understand how the weight isn't falling off you as I easily eat twice as much as you and my weight is stable. If I could stick to even 15-1800, I would lose easily.
