I found that certain women at my last place of work got VERY interested in my lunch when my weight loss became obvious. They were the very, very dull people who were utterly obsessed with calories and 'syns' and everything they put in their mouth they had to comment on to each other
'Oh have you logged that hun?'
'These are amazing, only 123 calories and 3.6g of fat'
'How much weight have you lost this week?'
Etc etc etc.
I didn't care, however the problem was - they tried every faddy diet under the sun, used weight loss pills, slendertones... but also ate a LOT of junk (they were always the first out to the kitchen when it was someones birthday and there were cake / doughnuts) so they didn't lose weight.
Again... each to their own.
After 3-4 months, I'd lost a fair bit of weight, so they started to talk to me about calories / fat etc. Despite saying 'I just eat healthy and don't eat junk food' (truth), they figured I had some magical 'secret', I wasn't telling them, so used to pounce on me at lunch and literally comment on what I was eating every single lunch time.
It got so bad, I used to wrap my lunch up in a box, clingfilm it so they couldn't see what was inside, put it inside ANOTHER plastic bag and go downstairs to the foyer to eat....
They then convinced themselves the only reason I was losing weight was because I was starving myself as they never saw me eating...
