I've been 56-58 kg my whole adult life except in pregnancy and postpartum and have never needed to diet so I'm totally clueless. Over the last couple or years I've put on some weight and I'm now 65kg. I'm still considered in the healthy weight zone but it feels too much for me. Clothes are too tight and most of the extra is held around my tummy and bum. I am 45 so no doubt age is playing a part. How easy would it be to lose 4 or 5kg? Would it be realistic to think I could lose it by my holiday mid August or am I kidding myself? Where do I even start?
