In a nude photo spread for V magazine, Christina Aguilera flaunted her pregnant body, which shows that she has gained weight only in her belly while she is lean everywhere else.

She said that she is proud to embrace her body through all stages of life while always being fearless and confident about the future. In the recent past, she made news after she lost a massive 35-pounds with the help of yoga, low-carb diet and staying active. There were rumours that she had undergone weight loss surgery or suffered from an eating disorder.

Her diet includes high-quality fats like avocado along with chicken breast and fish. She indulges in healthy snacks like almond butter with celery.

During her pregnancy with Max in 2008, she indulged in foods like baked potato, steak, fried chicken and macaroni and cheese. She lost 40-pounds after that by doing cardio workouts and weight-lifting for 90 minutes in a day, five times a week. She followed strict diet of proteins, vegetables and whole grains which totalled to 1,700 calories a day.

Despite not being a workout fanatic, she makes sure she does regular exercise and this is what makes her motivated and confident as it makes her body feel stronger.

Low-carb diets help in reducing hunger which ultimately helps aid weight loss. They are very effective in removing harmful fat from the abdominal cavity. It helps increase the level of high density lipoprotein which is 'good' cholesterol.

Megan Fox, lost her pregnancy weight in record time while on the Paleo diet and Kristin Cavallari, too, lost 20 pounds in 2 months on a diet that involves grass-fed beef, bison and coconut oil. Kristin completely eliminated processed foods from her diet and she makes it a point of reading about anything that she eats. Other celebs who took to the Paleo diet are Tim McGraw, Jessica Biel, Robin Wright and Joe Manganiello.
