Can I ask how many calories you eat on a glp 1?

Just curious. I’m also on my own non glp1 weight journey. No judgement around it whatsoever. Please can you disclose how many calories you consume. My issue is that I genuinely just eat out of boredom and having not made good choices post motherhood. I’ve lost 15 pounds very slowly. But I have made some good changes. Ie getting ready (bit of lippy) and walking to the local coffee shop instead of eating a packet of biscuits in front of the telly when bored.

Just seen a lot of friends who have always struggled with weight and had issues like pcos and thyroid issues lose weight very effectively. I can definitely keep to a deficit.

This thread is really quite frightening. There’s no way anyone’s maintenance calories are 1000, even a small child requires more than this a day to stay alive. Eating 800 calories every day is an eating disorder. You’re unwell and need help.

An adult should be consuming absolute minimum 1500 to survive. That’s just if you don’t move around at all. Obviously when trying to drop weight people reduce down to 1200-1300 or something and feel ok. There’s just no way anyone feels sustained on 800 cals unless you literally don’t move at all.

I lost a lot of weight years ago pre jabs and I did it initially through the 5:2 diet. Fast days were super hard for me, I felt moody, had headaches, would shake etc but I persevered for a few months till my appetite reduced overall. On non fast days I’d eat about 1400-1500. I also exercised every day- either a YouTube HIIT video, dumbbells or running. Lost the 7 stone in a year and kept it off. Now a perfectly healthy weight and long distance runner, I’d guess I eat 1800 a day.

People keep referring to small children as though being physically small means they must need the lowest amount of calories of any human.

Do you know what requires a fuckton of extra calories? Rapid growth and brain development.

Babies feed every couple of hours, by your logic the rest of us should eat ten meals a day to compete.

Honestly? Probably 600-800 per day. Not deliberately, but because I just can't stomach any more. I'm absolutely stuffed to the gills with an apple.

I'm not on it anymore, I came off it last year after hitting my goal weight but when I was on it it was nearly impossible to eat much more than that.

And now you’re off it @LordofMisrule1 still only consuming 600/800?

Zempy · Yesterday 11:46

Whilst losing, around 800 to 1000 calories a day. Now I am in maintenance I consume 1200 to 1300 to maintain a BMI of 20.

Safarisagoody · Yesterday 12:44

I’m shocked at how low some of these are. I’m up at 2400 or so to maintain a bmi of 20 at nearly 5ft 7 and mid fifties, post menopause.

I understand if chair or bed bound, or very petite, but I am struggling to comprehend how so many are eating so little and are apparently active, how are people even getting enough protein.

if I was eating so little my muscle would have wasted away, I’d be a mess of saggy loose skin, and by body would look like a deflated ballon, hunched, with a flat arse and no muscle.

It’s good you’re eating more then. I can assure you I haven’t “wasted away my muscles”, I’m not a “mess of saggy skin”, nor do I look like a “deflated balloon”. I’m not hunched either and my ass is not flat. In fact, I look and feel great.

I hope you weren't suggesting that people who eat less than you look like that, as it would be quite rude.

For those on 700-800 calorie diets -
you will not be getting enough protein,
nutrients or energy from this diet for healthy functioning. You will not be hitting basic daily energy requirements. Of course you will lose weight! But you will completely mess your metabolism and your endocrine system in the process.

Why do you think you seem to be only able to eat 1000 calories after doing this without putting on weight? It’s because you’ve slowed your metabolism, messed up your hormones and lost muscle.

Please listen to some of the posters on here who have lost weight sensibly without going too low on calories. They then built muscle and now eat a decent amount! Without putting it back on. That is sustainable and healthy. Love those on 2000 plus calories! The muscle needs this.

A diet of 800 calories and less should be done under strict medical supervision - what does that tell
you?

I've lost nearly 12 stone
Never gone over 1000 a day
Currently it's quite low about 800 as I'm a bit fed up with what I'm eating

I know you didn’t ask me but I’m just jumping it to say feeling hunger is absolutely normal and apart from the very early days I have felt hungry often. The difference is the WLI stops me from eating everything - I do not want it to stop me having hunger cues as I want my eating to be as normal as it possibly can be which means having an appetite.

I'm stuck at home , little chance to get steps in
Having done yoyo diets my entire life ,my metabolism is shot to peices ,I'm in menopause and I just don't burn fuel efficiently
I have tried eating more and I just put weight on .
I'd love nothing more than to be able to eat 2000 calories a day
But if I did ,I'd be right back at where I started,12 stone heavier

Macaroni46 · Yesterday 13:43

As a shortie I’ve only been able to lose on 800-1000 per day. Any more than that and I maintain. That’s with 10mg of mounjaro. And the loss has been slow. 11 months to lose almost 3 stone.

Any chance of doing some weights? I do think the key to being able to eat a decent amount long term is to put some muscle on.

I concur if for reasons out of your control you have to be inactive then you will need less calories

Fully agree, I think you never feel hunger your dose is likely too high.

I aim for 1500 a day or thereabouts and am on the lowest dose. I did worry about making it too easy for myself and then going back to old habits eventually so I'm hoping this will be more sustainable for me. I've also upped my exercise.

I didn’t even intimate that, I was very clear. It’s rhe people eating very low cals. The 800 odd a day we are seeing, even up to 1000. These are very low cal diets. It’s great youre firm and muscular on that, I would not be, and I’d suggest it’s unusual,

Viviiene · Yesterday 13:51

Those who are now counting calories are you making massive savings as eating probably half what you used to?

Does it surprise you how much you used to consume compared to what you eat now? Genuine question, I'm not being goady we've just heard for years that eating less and counting calories didn't work. Can you now see that it does?

You’re right, I was utterly fed up with it, I was eating the same stuff every day just to hit my calorie and macro targets. Recently, I’ve made more effort to learn new recipes and now have a much more varied and tasty diet. All part of the learning process!

Yes ..the less active you are ,the less you can eat
I've recently bought a rowing machine,and I'm starting to build up using it each day .
I do hope very much to be able to eat like a normal person one day

When losing 800-900. Maintenance for me is 1100 ish.

@LaurieFairyCake , are you taking a maintenance dose and if so how much please? I am at my goal weight and titrating down the doses, presently at 7.5mg. My weight fluctuates a bit usually between 107 and 108.5Lbs; I’m 63 and 5’1”. I estimate my average daily calorie consumption is approximately 1800 which to be honest I can’t understand because in theory I shouldn’t be able to have that much especially since I also have hypothyroidism. I can only imagine the medication is making my metabolism work particularly efficiently, I would like eventually to get to 5mg but I’d rather not have to consume less.

GPL-1 also impact your blood sugar and the efficiency with which you burn fat so the weight loss isn’t purely down to calories in/calories out.

I don’t get that, genuinely don’t.

I’m 5ft2 and have lost just over 1st in 9 weeks, on around 1200-1400 calories a day.

(Not on WLI, but the deficit would be the same either way)

What does being short have to do with it? How short does a person have to be to genuinely need less than 1000 calories?

MargoLivebetter · Yesterday 15:21

I lost slowly on MJ, my weightloss averaged 1.8lb per week. To lose, I was on 1100-1300 calories a day. To maintain, I am on 1300-1600 calories a day. For maintenance, I look at that as a weekly average, as there are some days when I eat out, where I will consume more and then the next day, I will make sure I consume less.

Everyone will be different and will find their own level. My calorie intake matches fairly well my energy expenditure, according to my watch/health app, now that I'm maintaining.

@Viviiene I think everyone knows that consuming less calories is a proven way to lose weight! Most people who take WLI will have tried many diets and lost weight. But what most haven't been able to do is stick with it long-term, change their eating habits and then maintain. For a whole variety of reasons WLI seem to make this more doable for many users.

Where have we been hearing for years that eating less and calorie counting doesn’t work? I have known since at least the 80s about counting calories and have never heard anyone say it doesn’t work?

In terms of finances I probably don’t save as much as expected by some as I buy far better quality food now.

The way I understand it is that the shorter you are, the lower your daily allowance is. I’m glad your weigh loss has been fast. I can only go on my own experience and mine’s been slow but I’ve lost nonetheless. I also am menopausal and have lipoedema which may well affect my progress.
