Regarding weight loss, it has always seemed to me a somewhat dreary and depressing thing to aim for. It's also quite hard, and requires patience. I think it better to focus on things like: eating well - eat nourishing, tasty food, get fitter and stronger and more flexible, ideally doing something fun or relaxing like sport, pilates, yoga, dance, walk in nice places, read interesting books or do something to enliven the mind, learn a language, whatever appeals. I think if you do some or all of these things, you will be healthier and happier, as long as you don't scoff biscuits.
