Why am I putting ON weight?

Look at the diet for type 2 diabetes. Ditch the potatoes, peas, white bread and pasta, and switch to carbs with a lower glycaemic impact - quinoa, buckwheat, wholemeal bread. Increase your intact of protein and leafy green veg.

OP check your hormone levels. At your age you may be perimenopausal. Your hormones may be off an impacting your weight.

Ultimately the injections have shown it’s all about calories in and out. Regardless of how bad the calories are. Are you really tracking your calories? Ie cups of tea or sauces like a previous poster said?

Good luck!
You can still eat quite a lot on 1400 calories.

I've been snacking on carrots and fruit throughout the day. So I've never been really hungry at 1400

I just wouldn’t weigh yourself. Stick to measurement or photos so you can see a difference.

Weight fluctuates for lots of reasons; hydration, where you are on your cycle etc.

You could also reduce your cals by 100 and/ or increase your activity levels and see how you get on.

I read a great article about how the first 3-4 weeks are learning / trial and error when it comes to losing weight.

I agree that 1700 sounds too much given your height. I’m taller and that’s only just under what I need to maintain. You definitely won’t be building muscle to the extent that it will have an impact on your weight but you can get some water retention when you start doing exercise which may be happening. It’s also worth remembering that hormones have an impact on weight too, I can easily go up or down a couple of pounds depending on where I am in my cycle/bloating.

I just tried another online calculator there.

I put in five foot three, and fourteen stone weight.

It said to lose one pound a week, you need to eat 1428 calories a day.

Don’t stop the exercise, it’s still good for you!

This is not true. Walking is good exercise and any exercise will contribute to weight loss, as long as you aren’t eating way more than you should.

I’m currently losing weight and my food intake is under control, but I notice a difference in how much is coming off whether I do more walking or not.

Weigh every day and note the trend over time, you can fluctuate massively day to day depending on lots of factors, particularly hormonally. Manage your expectations, 3 weeks is not really long enough to see a significant difference, especially if you’re not weighing daily. Also do photos/measurements as the scales are not the only marker of progress.

If you’re on IG follow someone like ESGfitness, I’ve learnt so much.

I use my fitness pal and find it really good.

I disagree that walking is useless for losing weight..the more active you are the more calories you'll burn. I lost some weight with a PT last year and when I stalled a couple of weeks , she'd drop the calories and up the steps and that tended to get things moving again.

You may still be eating too much to lose and just be gaining slower that you were previously.

Walking and those weights won’t be doing much for weight loss.

1300/1400 is more realistic to lose 1lb a week at your age, weight and exercise level.

How often are you weighing yourself and what time of day are you weighing yourself?

Weighing in the morning after going to the loo is best for consistency. If I weigh myself in the even it can vary by a lot depending on what I have eaten or drunk that day.

It can still vary a fair bit in the morning. I weighed a pound more this morning than yesterday but I am not concerned as the overall trend is that my weight is going down.

I don't think 1700 calories is right.

Online weight loss calculators don't factor in people's height properly.

If you're short and five foot 3 is short, you need to eat less calories to lose weight.

I'm eating 1400 calories at five foot 3. And I've been losing weight.

Walking is better than nothing for your heart but absolutely useless for losing weight. It’s 95% diet and 5% rigorous exercise

I wouldn't jump down to 1200 but maybe drop a hundred and see where that gets you.

You're not a nibbler are you?! I'm a terrible nibbler, little corner off this, a couple of pieces of that and before you know it I've nibbled through 200 calories.

I don't think 1700 is the right amount of calories for you to lose a pound a week.

Especially as you are a short woman.

I'm the same height and weight as you. I'm five foot three and fourteen stone one pound.

The calculator I used told me that to lose one pound a week , I need to eat 1400 calories a day.

1700 calories is not right if you want to lose weight. You'll maintain weight eating that amount.

Use another weight loss calculator.

Are you weighing every day of the week and then averaging it each week to see if there's a decline that's the best way. If you only weigh one day you won't get a true number, you could need the toilet, be holding more fluid due to sodium intake, could be hormonal.

Calorie counting is dubious. It makes you obsessive, and not all calories are equal. Not to mention the fact that many food labels aren’t accurate.

are you eating mostly veg, a bit of meat, and no sugar?
