I used to teach KS3, GCSE and 'A' level Textiles, KS3 Food, GCSE Child Development, KS3 and GCSE R.E. and PSHCE. So I know my way round the NHS guidelines on 'Healthy Eating'! My whole life has now changed - for the better. Work-life balance is back!
Unfortunately you will find a lot of shops stocking clothes which fit! 30 odd years ago, I kept my weight down because I found it difficult to find large clothes. Plus sizes now are doing the general public no favours, just adding to a 'growing' market of profit for the retailers and manufacturers.
Son was overweight and now gone down 4 clothes sizes as I have stopped feeding him loads of food!
I put on and lost weight quite a few years ago but it all went back on and some more. With the LCHF, I didn't think about trying to lose any weight as it was too difficult to think of day-to-day. Just made sure I eat very little at each meal. Weighed myself every morning and steadily lost 2 - 3 lbs a week. kept track on a chart as I still do now. 6 months in to my new way of eating, I used an app to count the carbs and calories and some days I was only eating around 600 calories but it did the job. My own version of the 'Newcastle Diet', I suppose.
I still track my weight and I still weigh myself every morning. A weight increase needs addressing fast.
I don't eat overtly carby food. If I can't find a food when we are out, I don't eat and wait till the next meal, as I don't find being hungry a problem. I'm aware could slip back at any point so can't be complacent. The Diabetes diagnosis was the wake-up call - the end of the line. A blessing in disguise.
