I know what you mean when you say you still "feel" fat. I did not lose even half of that kg's, but in school I was 87kg the day of my matric dance. I now weigh 70kg and somedays - I still feel like I weigh 87kg again! I have more good days than bad and I LOVE my body, just sometimes my body does not like me
What helps me to feel better is getting toned. The fact that I can do a few reps of sit-ups, makes me look at myself different. Maybe all you need is to get your body toned? I know it can be hard with kids around, but do try and make time for yourself. You can lose loads of weight, but when you do some toning, you get an instant "butt-lift", kwim. As soon as your butt lifts as a result of toning, you can fit into clothes better and that makes me feel better about my pear-shaped body.
Walking is great for weightloss, but try walking with dumbells and get your arms moving. Constantly picking up kids is also great for your biceps :P Just crunch your tummy muscles as you pick them up and get two flies with one slap! I crunch my tummy and squeeze my butt when I walk up stairs - silly, but it works. Getting muscle will put on weight, but it's not the tire-around-the-middle or love-handles (that's me) type of weight, its good weight.
If I am being forward, please excuse me - I am on a gym high this morning
ps. Absolutely bloody marvalous losing that much weight!! Give yourself a pat on the back, hun!
