Always Hungry

I feel like I am hungry all the time, it's like my stomach is never full. I want to loose weight and if I keep eating like I do I'm going to gain more weight. I didn't gain any weight during pregnancy and I lost 14 lbs once I had her but I gained back 7 lbs since also.

I want to join a gym this Friday but I also don't know what to do or how to eat right.

Any advice? No rude comments, Google sends me to all these websites that

they want you to pay for this or that.
