Fitness fanatic Lauren Simpson recently revealed that she was once obsessed with fitness in all the wrong ways, avoiding carbs, sticking to cardio and letting “the number on the scale rule my life.”

THE FOODS THAT CAN HELP YOU SLEEP BETTER (AND THE FOODS THAT MIGHT KEEP YOU UP AT NIGHT)

“My health deteriorated as a result of punishing my body — under eating and over training,” the Australian woman confessed in a candid Instagram post on Wednesday.

Things changed for the better, however, when the gym-goer embraced weight training and a more positive approach to eating on her journey to a healthier lifestyle.

“Biggest game-changer for me was weights training and shifting my mindset around food,” the 29-year-old explained. “Lifting weights and learning about resistance training built my confidence and created shape with my body. I learned food was not the enemy.

“I no longer wanted to be ‘skinny’ - I wanted to be strong!”

Since 2015, Simpson has gained about 20 pounds by training hard and increasing her caloric intake from a mere 1,000 to a healthier 2,000 calories each day, The Sun reports. And today, she’s never felt better.

“My journey is far from over - I see myself as a work in progress,” Simpson said.

“My journey is far from over — I see myself as a work in progress,” she continued. “I’ve learned that the beauty isn’t in reaching your end goal, but it lies within finding your true self and being proud of your successes along the way.”

As for favorite fare, Simpson keeps it simple in the kitchen when she’s “shredding” for a bikini fitness competition, according to The Sun. The fitness fanatic will eat a two-egg omelet loaded with cauliflower rice, baby spinach, cashew nuts and tomatoes for breakfast, later digging into fish with potato wedges, mushrooms and green beans on the side for lunch.

Before a workout, Simpson likes rice cakes with tuna, tomatoes and a cup of coffee, finished off with fruit for an afternoon snack. She also loves a chicken salad for dinner, and smoothie bowl with blueberries, almond milk, peanut butter and protein for an evening treat.
