Cathy is 66 years old. She loves traveling and spending time with her kids and grandkids now that she’s retired. But in the past few years, she started feeling fatigued, having trouble with her weight, and despite treatment had dangerously high cholesterol levels.

“I just felt off,” she says, “and every doctor I saw just told me to eat right and exercise more.”

After taking her doctors’ advice but finding her weight didn’t budge and she still felt tired, sluggish, and medications weren’t working, Cathy decided it was time to find different answers.

Dan is 62 years old with three grown children and one four-year-old granddaughter. A few years ago, he and his doctors decided that knee replacement surgery in both knees would improve his quality of life. However, he also learned that he would have to lose a significant amount of weight before his surgeon would operate on him.
