The only way to reduce overall fat and inches is to lose weight.
You cannot spot reduce. No exercise or "magical" food will cause your body to take fat from one place over another. Only your body decides where the fat is being taken from. We have no control over it.
Your stomach will go down given time. You're not going to be at goal weight with a 52" waist... that's just ...not possible!
Losing inches, just like losing weight, takes time. I hear you about wanting to be healthier... but you're already
making the changes you need to be making. You've made exercising a habit, and you're watching what you eat.
There's not a whole lot else to be done other than to have fun trying new activities, and find the joy in eating healthier. After all, this is forever.
