If you restrict your intake of processed foods, grain/gluten, and sugars for a week or two you'll definitely see some weight disappear. Especially if you're used to having those things in your diet.
If you want to go the extra mile try making some broth based veggie soups and have a bowl of that for at least one meal a day.
You can also cut out some of the more sugary fruits and simply stick to meat & veggies for a week. If your body is accustomed to a lot of these things I wouldn't stick on a meat & veggies diet for too long or else you may see some adrenal withdrawal and that would be hard to deal with.
Hope that helps!
