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.

I’m 5ft 8, started 19st 5lb, now 9st 10lb and in maintenance so does fluctuate a few lbs either way. I’ve never eaten less than 1300 a day, I was on around 2000 at first and then reduced as my weight and TDEE reduced. I can maintain on 1300-1500 a day.

800 is likely too low for most people, but 1000 not necessarily so. I'm short, very active, fairly close to goal and I am losing 1-2lbs a week on 1300. It would be less if I was sedentary.
I was overweight because I listened to too many people tell me that what I thought should be my maintenance and deficit was 'toddler calories'.

It obviously isn't recommended for someone to go from eating 3000 calories a day to barely eating, but how much each person needs varies a lot.

But there is a difference between 1000 and 1300 calories a day. I am not denying people who are shorter will need less calories but you are proof that weight can be lost on more than 1000 calories.

LaurieFairyCake · 01/06/2026 17:55

Obviously I’m saying proof for ME 😂 I’m 4.5 inches shorter than you.
my maintenance is 1100, if I eat more I put on weight

I’m not suggesting you are lying, but you said another poster was incorrect and said your experience is proof. It’s not. It’s just your experience.

glutenisthedevil · 01/06/2026 18:05

For my age, height, activity etc. my TDEE says 1300 calories for weight loss and 1800 for maintenance. On average I'd say that I usually come in at 1200-1300 per day and I'm losing around 2lb per week. For me, the jabs don't give massive suppression so I don't struggle to consume calories, and I don't mind that as I'm not afraid of feeling hungry; it's something I'll have to get used to when I'm no longer on them. What I do love is that they take away the constant food noise.

I'm proof based on over a decade of strength training to give me a considerable amount of muscle mass for my size, which means having a higher than average BMR. As well as still strength training 2-3 times a day I do a sport 3-5 times a week and I use a walking pad at home to get 10000 steps a day. That is neither realistic or sustainable for many people, and I'm in a privileged position of having the money, free time and good health to do these things.

Again it was because of people telling me that I couldn't do this level of activity on 'toddler calories' that lead to me feeling so confused about what I actually needed. Please don't make blanket statements as it's really not helpful.

peakygull · 01/06/2026 18:28

Absolutely no idea. I’m eating what I want, but trying to focus on protein and fibre. Don’t restrict myself. I had 20lb to lose to get to target and it took about 3 months, I’ve extended my target slightly now, it’s just been much easier than I anticipated. I’m planning on staying on it, it’s been life changing not being ruled by food noise.

GaurdRails · 01/06/2026 18:32

I am not on glp 1s but am dieting through calorie counting. At 5ft tall with 8lbs left to lose I'm keeping my daily calories to 1200 and losing about 1lb a week. I wouldn't set a target below 1200, I really think this is my limit to make sure I have energy.

Gardenflowering · 01/06/2026 18:40

700-900 a day.

Nausea horrendous.

2.5 stone lost in 11 months so around 1lb per week, some weeks zero loss on those calories.

No light headedness at all.

Intake greater than 1000 cals per day results in around 2-3 lb GAIN a week for me.

There are lots of people who eat far too little on a glp1 because they have it in their head they need to loose faster and don't understand the risks of malnutrition.
I have lost over 80lbs in a year and a half. Some months big losses, some months slowly. My starting calories were about 2300, now I'm around 1600/1800 depending on how active I am but tbh I don't really calorie count any more.
The biggest thing it has helped me with is portion sizes. I can eat a normal person's dinner and be full which had never happened me before. I also crave snacks and that has been lessened but it is still possible to overeat. I just really try hard to not restrict on snacks as I will binge and instead try to have a normal portion or figure out something else to do instead.

Anyone eating 800/1000 calories is doing harm to their bodies and are the ones who have higher risks of osteoporosis or gallbladder issues. A toddler needs more calories than that and the glp1 is just facilitating an eating disorder at that point.

You have lost over a stone and you can recognise where you're biggest downfall for food is. That's amazing. Don't get disheartened by other noise. A GLP1 is for life because it addresses metabolic issues, if you can diet and keep it off without them keep going. I'm not gatekeeping, I'll always support taking them if needed but it's not a short term solution and if used as such, causes more health problems in the long run.

This is a great post.

I’m sorry but nobody (and I don’t care how short you are!) will be getting enough nutrients and energy from less than a 1000 calories a day. You are just storing up problems for the future which may not be apparent now. Particularly those on 700-800.

The reason you seem to put on weight when you eat more calories is because you’ve most likely messed with your metabolism (and hormones).

You’d be better doing it slowly and steadily but with enough calories.

There are times that medical staff will recommend 800 calorie a day diets for some people. People should seek medical advice rather than Mumsnet lore.

Right but not the general public let’s be honest. An otherwise healthy woman needs more than 800 calories. If there is a medical need that someone needs that little food then that’s different. I can’t see anyone on here that has been advised to eat 800 calories by medical staff.

I think that’s pretty short term though usually? Things like extreme dieting when needing to get to a better weight for surgery? I don’t think many people would be advised to be on that kind of deficit for the length of time it takes most people to see through their weightloss journey. It’s a means to an end.

MissFancyDay · 01/06/2026 19:33

Iv'e lost about 7 and a half stone over about 22 months on Nutrachecks recommendation of 1200 calories per day.

I didn't calorie count at Christmas or special occasions. Losing it relatively slowly has left me with nowhere near as much loose skin as I was expecting, even though I am late 60's.

I’m assuming you mean strength training 2-3 x a week not a day!

but I agree with you. I’m 5’3” and strength train with heavy lifting 4 x a week. I also get my steps in

I’m postmenopausal I’m a size 8. I have a lot of muscle mass for my size and I can hip thrust nearly 4 times my body weight. I’m very strong. I have very defined arms and my core and my glutes are rock hard when tensed. I can’t eat that many calories a day or I will gain body fat. I have to stick around 1200 And the fact is, if I wasn’t getting enough from that I wouldn’t be building a muscle I’m building.

True, but nor are people on here saying that they're planning to eat 800 calories a day long term. For someone who is very overweight and has related health conditions it may be advisable to lose weight as quickly as possible initially, even taking into account risks such as gallstones, because those are lower risk than the other conditions they are living with. And for very short post menopausal women, 800 could be a necessary deficit to lose weight at a slow rate on a short term diet. It isn't going to be the majority of course, but blanket statements don't help with something as complicated as weight loss.

no, what I said is proof is that I’m healthy at maintaining at 1100 calories. My DEXA scan says so, my low inflammation says so, my disappearance of pre diabetes says so.

What I was responding to is the ‘health’ claims by another, that I’m on ‘toddler calories’, ‘storing up trouble for the future’, at risk of ‘osteoporosis and gallbladder’ problems.

No, no, no and NO. I didn’t lose weight fast, my
’losing weight’ calories were 800-900. My maintenance is 1100. I’ve been maintaining for a year.

fantastic that others can eat more but the whole point is that NOT EVERYONE IS THE SAME. And when posters say you’re going to get ill or you’re not eating enough or you’ve got hormone problems or you’ve destroyed your metabolism it’s perfectly fair to come on and say NOT MY BODY, not my experience.

Sorry yes! 2-3 times a day would be a lot even for me 😁But yes, up to eight overall exercise sessions for me a week, plus steps, so it isn't as simple as 'i can lose on 1300 a week and everyone else should too'.

That's a seriously impressive hip thrust btw! I'm hoping that if I lose a few more kilos I'll regain my ability to do pull ups!

100% agree wholeheartedly with this!!

Thankyou for beautifully putting into logical words what I have been stumbling through and trying to say.

But people just do not get this and will argue strenuously about “starvation mode” and “ not eating enough” and “go to the Drs, you are not right” all of which I have read on repeat on these threads.
We are not all the same, I know from 50 years of living in my body, what does snd doesn’t work for it.
For the first time in around 12 years what I’ve been doing for the last 11 months (the same method as you) is the ONLY thing that has worked. And believe me, I have tried everything.

It does get exhausting when people go on and on about malnutrition and starvation mode. It makes me want to not even talk to anyone about weight loss because they are so 1979 in their thinking.

It also explains why we're all so overweight, as a society, because people literally think that they can starve even though they've eaten all of their calories and nutrients, in surplus, for years.

So, people end up overeating and being frustrated when the scales don't move or move in the wrong direction, because they're told by people who have no clue that they'll starve even though they are large and actually do need to eat a lot less. They are just trying to do the right thing but getting incorrect information.

Dr Now (American bariatric surgeon) once told a woman that she wasn't going to suffer from malnutrition because she'd eaten all of her nutrients for the next 4 years. She was so mad at him for saying this but it made sense!!

I have previously put my calorie level here, when asked, and had posts deleted. It's ridiculous that misinformation that results in unhealthy outcomes i.e. obesity/overweight, is allowed, but not counter arguments that promote healthy BMIs because they are not 'popular' amongst those suffering from obesity or overweight.

I once lost more than 80 pounds eating 1800 calories a day but that's because my starting weight allowed me to lose weight, quickly, on a higher amount of calories.

As we lose and get closer to goal weight, the calories required to lose shrink further, and that's especially true if one is sedentary, older or petite.

Summerhillsquare · Yesterday 05:55

Dunno. The point was to relearn sustainable eating habits. 3 moderately sized balanced meals a day, lots of veg, basically. Calorie counting and 'dieting ' isn't sustainable.

Is the nausea constant? How long have you been on them @Gardenflowering ? Does the nausea not seriously impact your quality of life?

farfallarocks · Yesterday 06:12

I’m tall but a super responder and i could not eat much at all at the lowest doses, some days 800 max. Lost 4 stone in as many months but then reverse dieted so addded 100 calories a week more and happily maintaining at 1900-2200 a day. Now focused on body recomposition and building muscle and never felt better despite the rapid loss

Rockgrin · Yesterday 06:13

I'm on my third week but haven't counted so far.

For me that was the point, to finally be free of the endless obsession, weighing and counting that had dominated my life since I was 11. The mental energy I was wasting on it was astounding.

I listen to my body and eat when I'm hungry and stop when I'm full. Because I actually feel full now! So far if I had to guess I'd say it is anywhere from 800 to 1500 on different days.

I haven't looked at the scales since the first week (lost 12 pounds) because I also want freedom from them, but the food noise was really coming back at the end of last week, so I am moving up to 5mg after my last 2.5 shot.

If I weigh in a few weeks and haven't lost on average 1 to 2 pounds per week then I will consider some form of tracking.

11 months. Nausea for the first 2-3 days (& headaches and feel very unwell) hence not moving up the doses.
Quality of life is impacted.

Weight stalled for the last 8 weeks. (On 800-900 cals a day) But I can’t face the side effects by moving up, in fact I have to prepare myself every week to jag myself because some weeks I just can’t face the next 3 days of feeling so unwell.

I also do not want to drop cals any more so here I am stuck.. if I stop the jags, I will gain a shed tonne of weight again and I don’t want that either.
