How do people become obese?

Before someone is obese, they are overweight. Their clothes sizes also change. Why do they wait until they are obese to try and lose weight? Do the majority of obese people have mental health issues?weigh

Because I like biscuits! Judge away but leave me alone 😆

On a serious note though, it’s not hard to figure out OP.

Long covid. Can no longer exercise, my body also can’t seem to respond normally anymore to lots of things including trying to minimise weight gain. It defies science in lots of ways now (including gaining half a stone in a month on 850 sodding calories a day) - some of those calories are thrown up too (getting sick if I forget to stand up slowly enough is another long covid pleasure). Previously I would nip it in the bud if I felt a few pounds go on and stayed the same dress size for years. However, many people for a wide variety of reasons won’t have been able to do that - surely that’s easy to understand? It’s a bit simplistic at best to say “why don’t they just….”.

We don't really need three meals a day. And big portions!

BePoisedPlumUser · 27/04/2026 14:42

I really like cake

TheHouse · 27/04/2026 18:35

Cos I’m a fat cunt who loves to eat and my husband also likes to still shag me.

In a nutshell.

It isn't something that happens overnight. It only takes a very small overeat to put on 1lb a month - over a year, that's nearly a stone; over 5 years and it could take someone from healthy to obese.

Metabolism can slow fo all sorts of reasons, most obese people did not suddenly decide to eat lots of cake, they ate what they'd always eaten but stopped being able to burn it off, and the weight crept up.

Me?

I had a disabled child that keeps me awake literally all night and spends his days chucking stuff about, so ended up just eating whatever was quickest/easiest/most satisfied my burning desire for something comforting. I spent the very little time I have, sitting down. Just sitting. In peace and quiet. With biscuits.

My metabolism is slower than your average snail, and for a long time that just meant my bum and boobs got bigger. Then I hit my mid 30s and “hello stomach!”

Then I got CFS (and still stayed up all night) so had even less energy to do anything apart from exist.

Now, I make my entire body hurt by walking steps I’d still rather not, and try and meal plan in the 0.2 seconds of time I have. I have binned all chocolate and crisps, and instead eat fruit. Most days, I’d still actually like a kebab. But I’m also going to die of obesity if I’m not careful, and see previous rant about disabled child requiring my existence.

HTH!

Come on Op- you can’t work this out?
Why do people smoke? Or fall into any bad habits? Do you live your life perfectly?

dottiehens · 14/05/2026 22:52

Cortisol, depression ,lack of sun, hormones and aging. Less to do with food really.

Eat too much?

Eat too much?

Ah there we go. Nice and easy.

Now everyone who is obese will know they just have to eat less. Easy peasy.

soundsys · 02/06/2026 00:11

For me it was the boredom plus stress of covid times. I was never overweight before, and I’m not obese anymore. I am still overweight but very nearly back to (my) normal).

honestly, I thought the same as you OP. I’d always been a size 8-10 and then sometimes got closer to a 12 and just ate less/exercised more and stayed a 10. Couldn’t understand why anyone ended up obese.

And then covid hit and I felt like I was losing my mind and a drank too much wine and ate too many biscuits, just a bit at a time, I guess! And all of a sudden…

oh as a PP said, anti depressants made it much worse! Having stopped them (gradually, as my mental health got better) I’ve found it much easier to lose weight!

basically: lots of reasons!

Ok- I’ll bite.

I am considered clinically obese (probably about 2 stone overweight). I have an underactive thyroid, which affects my metabolism.

I also have arthritis, and an autoimmune disease.

At the moment, I’m managing to stay active. There are times when I have more difficulty with this though, and I’m guessing that as I age (I’m 60 now), movement will become steadily more difficult. So I’ll get fatter.

Think I’m happy about that? I’m not.

My friend is a lot more overweight than I am. She’s had huge trauma in her life. Trauma often leads to addictive behaviours. She doesn’t drink, self harm, or take drugs like some people do. She eats. To cope.

Yes, that too is a form of self harm.

Its not just people being greedy.

Our supermarkets are full of UPFs. People are growing up eating foods that are designed to make you want to eat more.

This is a health crisis on lots of different levels.

Most of them do it on purpose because they like having people make goady threads to body shame them.

The remainder are just thick and don't notice/understand what is happening.

Honestly op: as @NormasArse has said, these things are way more complex than you can perhaps conceive?

I’m under 5 foot tall. I am only able to eat 1000-1100 calories every day without putting on weight.

OBVIOUSLY that was impossible so for 30 years I fought my body, tried every diet and exercise going. I had SO MUCH WILLPOWER that it took me 30 years to put on 8 stone.

Can you do the maths on that?

Thats an average of 1200 calories a day. I fought that hard that 2 digestives extra on top of my allowance caused me to put on weight. I was hungry every day for 30 years. Ravenous all the time.

Now I can eat 1000 calories a day and not be hungry (Mounjaro). It takes a 10mg maintenance dose for me not to ‘overeat’ and put on weight. This is just how I’m built.

No one can eat 1000 calories a day and not be hungry, it is not a moral failing. It’s just fucking biology.

You sound just like me. And Mounjaro has been the best thing for me too. I’m hungry a lot but I feel better than I have for a long time.

it doesn’t take much overeating to be enough to get to obesity. Especially when you are 5 feet tall. Life is very stressful and difficult and eating is very comforting.

Pyjamatimenow · 02/06/2026 00:27

I put on weight very easily. For me it would be as easy as going on holiday once a year, Christmas, putting on the 7lb that I can easily gain over both those events, not losing it in between and then the same events again.

Thaks for everyone’s input. I understand the struggle all too well having being overweight but fit most of my life. For me , it definitely started with being overfed as a child. However, I went on to the obese range post pregnancy and had to follow a strict diet to get to a healthy weight. Over the last few years my steady weighr has shifted to being 10kg heavier. However, I make a point of not changing my clothes size. If I can no longer fit in to my size, i need to lose the extra weight (which is not easy). I was genuinely interested in the answer as my friend circle comes in all shapes and sizes and the obese friend had a disordered relationship with food which she recognised.

If I can no longer fit in to my size, i need to lose the extra weight (which is not easy).

For me it took a low dose of Mounjaro to make losing the extra weight “not easy”. Before, that I yo yo dieted and tried bloody hard for 30+ years and it was impossible to sustain, gaining weight as I went along. For others it takes a high dose to make it “not easy” but achievable, for other they choose a surgical route.

Be glad for you that while it is “not easy”, it is possible. You might find as you get older or your body changes in the future and it isn’t always that way.

Maybe it’s biology and I need a little extra help to get to your “not easy”, maybe it’s psychological, maybe environmental, what I have eventually wrapped my head around is it isn’t because anyone is better. No one knows for anyone else how easy or hard they find their obesity, so maybe we all just focus on our own challenges and we all congratulate each other trying to improve our health regardless of how we do it.

What kind of public transport do you use with seatbelts

I became obese after having children. I went back into a stressful job, had a couple of traumatic life events so never bounced back and just kept eating for two. Then I felt worse and ate more and before I knew it, I was very overweight. Age doesn’t help either.
