I have similar issues but like Marydean's philosophy. Sounds like it's just your body shape. I call my butt my "stores" it's where my body stores it's fat and apparently it's a good place! MUCH better than storing it around the tummy... less chance of disease like diabetes.

I lost quite a lot of weight 2 years ago but the proportions stayed the same.... and i looked "scrawny" up top. Now i aim to maintain a healthy weight and learn to wear flattering clothes. Belted coats and dresses are very flattering

What REALLY bugs me is that i don't drive and walk at least 4km a day... but my legs are still fat.... no it's not just muscle it's fat you'd think my legs would be burning it off??? Maybe when i start to drive my legs will shrink and waste away a bit? LOL
