Yes, but you will really need to limit your foods. Try to avoid any fried food, and watch your portions for regular food. Don't eat until you feel full. Stop when you feel comfortable. And it's okay to go to bed a little hungry. It's actually better to.
Go for a walk once a day. You don't need to run, jog, just walk.
Always weigh yourself first thing in the morning before eating. That gives your true weight.
