Fantasia Barrino is looking healthy and fit after dropping 20 lbs. with a low-calorie diet and a commitment to fitness.

“In the industry I am in you have the pressure of perfection — and I definitely gained a few pounds,” the singer, 32, tells PEOPLE.

Finally she decided to take action. “Fantasia’s program [involved adhering to] a 1,200 to 1,400 calorie a day diet [that included eating] lots of protein and low carbs, drinking only water, and also eating every two to three hours to keep her metabolism boosted,” Rachel Roff, owner of Urban Skin Solutions, tells PEOPLE.

Barrino used the medspa’s medical weight loss program to get her health back on track.

Urban Skin Solutions helped me look better and feel better without taking shortcuts or going under the knife,” says Barrino.

The American Idol champ also stayed “extremely active” during her weight loss journey.

“Fantasia is a fitness junkie,” says Roff. “She loves hot yoga and she has a trainer that she works out with on a regular basis that incorporates cardio and strength training.”

“I have lost the weight and I feel great!” adds Barrino.
