I have always been slim - size 8-10 and about 5 ft 7. Didn't put on much weight when PG, lost it when BF, DD now 6 and over the last year I have started to put on weight - mainly since Christmas though I think. No scales in this house but I reckon a stone or so - enough that I have a distinct muffin top when naked and can't get into some of last summer's clothes. I gave up smoking last summer after 10 years and suspect that may have contributed.
I am sort of veggie - I do eat fish on occasion (maybe twice a month?) but no meat for the last 20 years. We only have wholemeal bread, but pasta/rice are 50/50 white and wholemeal. Loads of veg, though not so much fruit. I think fundamentally I eat good food - certainly enjoy cooking - but probably too much fat. I love cheese and olive oil and salad dressing [mmmm]. I crave carbs, fat, and salt and when I eat I can't really stop until I am full to bursting. Generally I only eat one 'meal' a day (evening usually) but will have 2 or even 3 helpings.
I don't eat breakfast. I suspect this may be part of the problem? But I just don't feel like food in the morning, and when I do have some I just get ravenous a couple of hours later anyway. I get really hungry in the evenings - right now I want a big bowl of salty buttery popcorn. Have been wondering if a vitamin/mineral deficiancy might be an issue maybe? Are there any that make you crave crap food and salt at strange times?
