Hit the Gym Regularly

To become more comfortable with skin-baring concert ensembles and revealing red carpet looks (like the plunging Roberto Cavalli gown Lambert wore in November 2013), the singer hits the gym -- hard. Working with a trainer while she's on the road, Lambert pushes herself at home with jumping jacks, climbing stairs and sweating through run-walk intervals around her 700-acre ranch.

Splurge in Moderation

She may splurge on fried chicken at lunch, but now Lambert will skip the leftovers at dinner in favor of grilled poultry -- saving 264 calories! Her light side: fruit.

Control Portions

The chart-topper (wearing Pamella Roland at the 2014 Grammys) skipped diet plans and simply made healthier choices. "There was no miracle. I'm just not a glutton anymore," Lambert explains.

Snack Smart

Though she tells Us, "There's nothing I love more than Cheetos," she skips the 150-calorie snack for nuts. Twelve almonds have just 80 calories.
