There was a time when Fergie's diet and workout consisted of snacking on fast foods and touring with her band Black Eyed Peas.

In her mid-20s, Stacy Ann Ferguson (Fergie) realized she was unhealthy and perhaps overweight -her 5-foot-4-inch-tall frame was weighing 90 pounds.

All that was about to change. According to the current issue of Shape, when she turned 30, it was time to start thinking about a healthy lifestyle.

Fergie's workout and diet changed for the better, when she adjusted her busy schedule to pay more attention to her eating habits and exercise. For her cardio, she walks on the treadmill at 2.5 mph and a 15% upgrade, spending some time walking backwards.

To tone her arms and shoulders, Fergie does push-ups and uses 8-pound dumbbells to do shoulder raises. For her triceps, she says "I squeeze backwards with little reps for three minutes"- I am not sure what it means, but it sounds like modified dumbbell tricep extension.

Fergie's diet is all about eating healthy and regularly. She eats low-carb and low-fat meals, five to six times a day. As Janet Jackson did, to be consistent with her diet, Fergie uses a meal delivery service.

Her favorite breakfast is a bagel with cottage cheese and tomatoes. She admits to occasionally cheating on her diet. Her favorite cheat meal, wait for it - pizza dipped in ranch or blue-cheese dressing.
