Wow, I wasn't expecting so many replies, thank you all so much. I've just read through them all and really appreciate everyone's insights and you've given me a lot to think about.
Some people asked a few questions about my lifestyle etc, so a bit more info. Late 50s, 9st 7, 5ft 3.5, size 32G boobs (more on them later🙄). I started a weight training programme 6 months ago and am progressing well I think. Not massive weights but more than I could do before and it's an instructor led programme so I'm always being challenged to increase to heavier weights. Also do pilates/yoga once or twice a week and walk an average of 55/65K steps a week (trying to get that to 70 but struggling).
Diet wise, breakfast is generally high protein yogurt and fruit, lunch will be salad or a sandwich if I'm out and about and dinner is generally chicken, veg and carbs like new potatoes. My downfall is chocolate. I usually have a couple of squares after lunch (dark 75%) and also dinner, and also most likely a chocolate biscuit with tea mid morning. So, I can see that's about 350 excess calories a day that I don't need (but also don't want to suck all the joy out of life!). Alcohol intake is pretty low, just a couple of glasses of wine once a week.
There's two big issues for me I think. The first is that - I know this sounds odd - but I genuinely fear feeling hunger when there will be no food available. I know it will make me snappy to those around me and I won't be able to concentrate or function well. Worst case scenario is being a passenger in a car in this situation when I'll get terrible motion sickness. Linked to this, I am convinced my need for sweet treats stems from childhood. My parents ate very sensibly (and still do), and sweets were viewed as a treat that you could have a little of now and then, certainly not before a meal and then only if you'd cleared your plate. The minute I left home I took great joy in eating sweets whenever I pleased. I often think of this when I read women on MN saying they strictly ration sweets with their children - it's not necessarily the right approach.
The second issue is what I feel is my disproportionately large bust. I've lost half a stone in the last 8 months but my bras were still uncomfortable. I went to get fitted, only to be told my cup size had actually increased and that this can happen through menopause to some women. I've just tried on a few dresses that were delivered this morning, they are all size 10 and fit well until I try to zip over my chest. If I size up, everything is too big on the hips and shoulders. I think I've felt worse about all this in the hot weather as they make me feel so uncomfortable. I'm embarrassed to say I even googled reduction surgery but I wouldn't be brave enough to do this.
Anyway, sorry for the essay and thank you so much for all your thoughts. I think I'll work on the portion control/protein levels/chocolate rationing. I also need to think more about what clothes work best for me. When I went for lunch yesterday, I did make an effort to look smart and felt good when I left, only to feel like a complete heffalump next to my friend!
