Life& Stylegets Jessie James Decker’s vacation slimdown secrets

hether she’s wearing brand-new pair of blue jeans or a skimpy swimsuit, Jessie James Decker always manages to look sensational — but it takes effort. “At 20, I could eat whatever I wanted and not work out,” the mother of Vivianne, 6, Eric, 4 and Forrest, 23 months, tells Life & Style. “Now at 32 and three kids later, I’ve had to adjust my lifestyle.”

Her winning food and fitness formula? The South Beach Diet ambassador combines the famous low- carb, protein- andvegetable-focused plan with plenty of circuit training. “I love to enjoy myself quite a bit on spring break vacation so right beforehand [I’ll] do South Beach for a couple of weeks,” says Jessie of getting streamlined for upcoming warm-weather revelry. “I know there’s a big rule on whether or not you should weigh yourself, but I personally like to weigh myself so I can stick to the weight that makes me feel best.
