Jackie ‘O’ Henderson shows off her svelte figure while shopping with daughter Kitty and mum Julie

She recently lost a whopping 12kg in three months after indulging in a healthier lifestyle.

And on Saturday, Jackie ‘O’ Henderson, 48, showed off her sleek new physique as she stepped into Sydney’s Bondi Junction shopping center with daughter Kitty, 12, and her mother Julie.

Looking slim, the radio queen wore a white patterned tank top, beige cargo pants, a shoulder bag and eye-catching sunglasses.

To complete her look, Jackie pulled her hair back into a ponytail and slipped on a pair of brown sandals.

Kitty, who shares Jackie with ex-husband Lee, wore a black racerback top and gray sweatpants, while Julie looked festive in a multi-colored polka-dot white sundress.

The sighting comes after Jackie shared a glimpse of her day on a board, following her recent slimming down.

Last month she revealed on The Kyle and Jackie O Show she regularly skips breakfast, a practice known as intermittent fasting.

She also avoids carbs and satisfies her hunger throughout the day by snacking on pre-cut pieces of steak.

“I cook steak and slice it, and then I just have a little piece of steak when I’m hungry,” she told her co-host Kyle Sandilands.

Jackie, who is an ambassador for the WW weight loss program, resists splurging on high-calorie foods for lunch, opting to eat just “three small pieces of steak” and a few Vietnamese rice paper rolls with fish and cabbage.

Kyle was shocked by her small portion size and told her, “A dog would eat more!”

For dinner, Jackie usually eats vegetables and a protein such as chicken or red meat.

Between meals, Jackie treats herself to smoothies and Starbucks Frappuccinos, a kind of blended iced coffee drink.
