“Christina has hired a trainer and is really dedicated to getting thin again,” said a source. “She lost 46 pounds from changing her diet and working with a personal chef.”
In 2013, Aguilera lost 35 pounds by following a low-carb diet that featured lean proteins such as chicken or fish, as Celebrity Health Fitness has reported.
Other celebrities such as Kim Kardashian and Megan Fox have hopped on the low carb bandwagon and experienced fast weight loss by adopting the low carb ketogenic, Atkins and Paleo diets.
Christina hasn’t stated whether she follows any of those diets, but makes an effort to eat low carb. Low-carb diets promote rapid weight loss by forcing the body to burn fat fuel, said Jeff Volek, author of the Art and Science of Low Carbohydrate Living.
Obesity expert Dr. Eric Westman, author of Keto Clarity, agrees. Westman has helped hundreds of morbidly obese people lose thousands of pounds on the low carb ketogenic, Atkins and Paleo diets. Reducing carbs and eating more healthy fats has been proven to aid rapid weight loss without hunger, said Dr. Westman.
Aguilera said yoga workouts and an active lifestyle spurred her jaw-dropping weight loss. “I did some yoga,” said Christina.
Yoga promotes weight loss by reducing stress, building lean muscles and suppressing appetite, said Jennifer Aniston’s yoga teacher, Mandy Ingber, author of Yogalosophy.
In May 2008, Aguilera lost 40 pounds just four months after giving birth to son Max by combining cardiovascular workouts and weight-lifting for 90 minutes a day, five days a week.
Christina also followed a low-carb diet like the Atkins diet, which Kim Kardashian used to lose 80 pounds. Aguilera’s weight loss comes shortly before she rejoins “The Voice” as a judge on season 8.
