I'm happy with my weight (just inside the limits for BMI) but I'm looking to slim down a bit. I think I follow a fairly healthy diet, have cut out drinking this month and started exercising in earnest from November last year. I've not really noticed any startling physical changes although I do feel slightly better about myself. Is there anything that works for slimming rather than weight loss? Should I up my exercise (currently 2 gym sessions a week and quite a lot of walking) or cut down my food (like pasta but generally few other carbs)? Also, I'm not weighing myself as I'm not really bothered about my weight. Is that OK?
