Please don't hate me, but I've always been slim without needing to exercise much, but started exercising properly about 2.5 years ago, and now see a PT fortnightly, and do lots of weights at home in between (but not tonnes of stuff: maybe a total of 2.5 hours over a week?). I'm starting to think maybe I've got a bit too slim, some friends have mentioned it (in a "have you lost weight?" Kind of way), and my clothes are definitely looser. I'd say I was always a big 10 at 5'7", and am now an 8/10, and am hovering at around 9stone, so I don't think I'm underweight, but 9 stone has always been a bit low for me in the past (and usually was a result of an extended period of illness). I don't watch what I eat, but I wouldn't say I'm an overeater (if I've gone out for a big lunch say, I'll usually skip dinner, or just have crackers and cheese or something, as would be full still from lunch).
I'm not really sure what (if anything) I should do about this? Has anyone else found this happening to them?
