Jennifer Lopez is feeling the burn after ditching sugar and carbs.

On day two of her extreme diet, the 49-year-old singer/actress admitted she was struggling with the challenge and is feeling “very hungry.”

But by day four, Lopez claimed on social media that she was doing “a lil better.”

The Grammy winner posted a selfie on Instagram Thursday where she proudly put her flat abs on full display while wearing a blue bra top and vibrant leggings.

Previously, the mother of 10-year-old twins shared the health challenge is meant to last a total of 10 days. Lopez and her beau, former New York Yankees baseball player Alex Rodriguez, revealed on Instagram they were embarking on the challenge together.
