Hey Harrypotterocks,
Dropping 53 pounds is an amazing job. So, first of all, well done. Don't be discouraged that you've not got to the body you want yet.
When it comes to fat, everyone is different. Your body will burn off stores of fat from certain places on your body first, before touching others. Whether it is your arms, legs, bum or stomach. Some people will lose weight from their stomach first but keep it on their bum for longer. Others will be like yourself where your stomach could be the last to go.
The important thing is to realise that your process is working. You're losing weight and burning off the fat. As long as you keep on with the same routine you've developed you will lose it.
Sometimes, it may not always be apparent what's happening with your body, especially when you look at yourself every day. So try and keep track - get a measuring tape and measure your waist. Then, after a couple of weeks, measure it again to check on your progress. (Just don't do it everyday, as your weight can fluctuate in the short-term depending on what you've eaten/physical exercise etc and provide inaccurate results across the long term).
Just note down the size changes and this can show you how much progress you are making, even if sometimes it doesn't feel like it.
