Next up in our "Heat index." Finding the determination to shed the unwanted pounds. We asked you 0 tell us how much weight you lost and got so many inspiring tweets, people losing 25 up to 15 pounds. We're about to meet a remarkable couple that did it as a team and, boy, did they succeed. Here's their story. In the spring of 2012 Jessica and Robert foster were a couple struggling with obesity. Food was my comfort and when I was feeling down or blue or angry, anything, you know, I'd just -- I ate. I kind of played the fat guy part and that was kind of what I saw as being my identity. Reporter: Finally fed up, they decided to change their lives together. She took up Zumba and encouraged rob to start running and changed their diets and eventually became vegan. Every time we dropped a pants or shirt size it did nothing but boost what was battered self-esteem from all those years before. Reporter: Their goal to be healthy role models for their four young daughters. I wanted to show these girls you can do anything you put your mind to and don't let anybody ever tell them that they can't because look at us. It's me. I did it. Reporter: Two years later they are transformed losing 280 pounds together. They did it all right. So are you ready to meet this wonderful couple? Come on out, Robert and Jessica. Oh. You look great. Awesome. Fantastic. So let's start with Jessica. Here's Jessica two years ago. This her of four weighed 287 pounds and worried about the threat of diabetes. She went on to lose 120 pounds and, boy, do you look amazing. Yeah. All right. So now Robert, he weighed 327 pounds. He didn't have any energy. Couldn't play with his kids. He said enough's enough and lost 160 pounds. He's running marathons. You guys look great. Come on over. That's fantastic. It is a pleasure to meet you. Nice meeting you. So inspirational to so many who want to do it but don't know where to start. What advice do you have? You know, I think the couple biggest things that I could say is, you know, you got to start off with the right goals, you know, so many people out there -- Meaning don't set them too high. Don't set them too high and don't make them short term. I want to lose X number of pounds. Once you get to the point where you lost that weight where do you go from there? You don't have to get an expensive gym membership. You did a great approach at home with milk bottles. We didn't buy gym memberships, all at home, cross fit in our home and that was kind of later down the line. We started off with very, very fun type of activities, though, because getting started is tough. And if you start with something that's fun that you can incorporate other people into, friends and family, makes it really easy and you get that high from doing, you know, physical activity and that exhaustion and you just crave more at that point. Easy and fun. Fantastic. Love it. You look amazing. A couple, a great team and hopefully our viewers are really getting inspired. Thank you so much for being with us.
