Now that you've sweated your way to a tighter bod, make some tiny adjustments to your supermarket list. "Including specific foods that hydrate skin, build collagen and prevent fat storage in your healthy diet may help keep cellulite at bay," says Christine Gerbstadt, M.D., a spokeswoman in Sarasota, Florida, for the American Dietetic Association.

"Anytime the skin is well hydrated, it will look suppler and healthier," says Lona Sandon, R.D., a spokeswoman in Dallas for the American Dietetic Association. On your tush, thighs and other spots prone to cellulite, a thicker, plumper skin layer will better cover the fat cells underneath. Aim for about 8 1/2 cups of water per day, Sandon suggests. Count the water that's in your glass, but focus as well on what you put on your plate. Don't love to chug? Foods that contain large amounts of H2O can help you reach your daily goal. Not only can snacking on these hydrating eats help you look sleek, but you'll trim down, too! Women who took in more fluid from water-rich foods, such as apples, grapes and cucumber, had a smaller waist and a lower body-mass index than those who took in fluids from beverages, a study in the journalNutrition reports.
