MISHAWAKA — From summer grilling to family get togethers, it's not easy to keep weight off once you've lost it. But there are ways to stay on track with a healthy eating plan.

Memorial Bariatric & Weight Loss Center Registered Dietitian Laura Jordan told WSBT grilling vegetables can be great because they add a lot of nutrients and antioxidants, plus they're very low in calories and fat.

Jordan knows it can be tough to make that option when more appealing foods are around. But she said you can still grill out and be healthy about it.

"There's a lot of lean beef and lean poultry choices," she said. "Pork tenderloins are great. Chicken breasts, even a T-bone steak can be lean if you cut the fat off it."

Jordan also suggests using a smaller plate to save calories, stop eating when you start to feel full and start reading labels.

Sugar free Jell-o has no fat, no calories, no carbs. Just half a cup of regular Jell-o has 80 calories and 19 carbohydrates.

You can also use the 50/80 rule. The first time you fill up your plate, you should leave 50% of it bare. After that you can go back for more food as many times as you'd like, but you should leave 80% of the plate bare during each of those trips.

Kirk Mason, Cari Peugeot and Kelli Cheatham began their Why Weight challenge in January. Now, 46 pounds later, they're done with the 12 week program, but still have a few final tests to go through.

Tune in to WSBT First Thing in the Morning on Friday May 2 to see their final results.
