"American Idol's" Fantasia Barrino dropped quite a few pounds this year ... and she's crediting her weight loss to some serious Hollywood pressure.
In a new interview with People, the "I Believe" singer was very candid about her yo-yoing weight over the years since winning "American Idol."
"In the industry I am in you have the pressure of perfection -- and I definitely gained a few pounds," she told the mag. That pressure led to action from Barrino, who has since lost 20 pounds.
Barrino's friend and owner of Urban Skin Solutions, Rachel Roff, also opened about the former reality star's hardcore fitness regimen.
"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," explained Roff.
"Urban Skin Solutions helped me look better and feel better without taking shortcuts or going under the knife," added Barrino.
"Fantasia is a fitness junkie," continued 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."
These days, Barrino says she feels "great" -- and has been flaunting those curves in some very sexy outfits lately.
