Danielle Cunningham 90-Pound Weight Loss: '16 & Pregnant' Star Shares Photo

16 & Pregnant star Danielle Cunningham has reportedly dropped 90 pounds since giving birth to her second child.

Earlier this week, the young mother shared several photos of her incredible weight loss on Twitter, and today, her weight loss secret was revealed.

"Danielle—who welcomed her second child almost a year ago, on June 7, 2013—credits the diet supplement ViSalus for her impressive slim-down," In Touch Weekly reported on May 23.

Although Cunningham and the father of her son, Jamie Alderman, have been on and off since the birth of their first child, Jamie Jr., they rekindled their romance in late 2012 and Cunningham became pregnant. At the time, Cunningham contemplated having an abortion but eventually decided to go through with the pregnancy and better herself for the sake of the baby.

After welcoming daughter Jayleigh Rae in June, two weeks prior to her due date, Cunningham vowed to get her pre-baby body back and began taking ViSalus and changing her eating habits in an effort to make it happen. Ten months later, she announced she had lost 70 pounds.

Now down an additional 20 pounds, Cunningham is sticking to a strict diet and continues to use ViSalus, although not consistently.

"She says the results came after replacing two of her three daily meals with their provided shake and allowing herself three snacks a day," In Touch reported. "Her impressive physique took form after she did the program 'on and off' for three months."

As for her exercise routine, Cunningham doesn't have one and recently told a fan that she "hates" working out.
