7 Ways to Be Healthier Now

"Lemon-besides offering a fresh and tangy flavor-has been shown to help with weight loss," says celebrity nutritionist Keri Glassman. "Add an ounce of lemon juice to each of your eight daily glasses of water for a quick antioxidant boost!" If you're on the go, add a True Lemon packet ($5 for 32; at truelemonstore.com) to your water for the same effect.

If you're short on cash, check your company's health and wellness plan before you rule out a gym membership. Many insurance providers reimburse a percentage of gym fees and some companies partner with fitness centers to provide discounted rates.

"Aesthetically, pulling your shoulders back and standing up straight can make you appear 10 pounds slimmer and more confident, but there are more important health benefits," says celebrity trainer Ashley Conrad. "Bad posture creates unnecessary strain on muscles, which can lead to fatigue, headaches, and low back pain. By correcting your posture you'll have more energy because blood flow isn't constricted."

Mint helps with digestion and eases tension and inflammation from colds or allergies. Replacing some of your normal water intake with a bottle of Metromint-a favorite of stars like Tom Cruise and Brittany Snow-provides a refreshing way to hydrate and add mint to your daily diet. Try all six flavors, including our fave, chocolate!

Instead of turning to an extreme diet, get fast, celebrity-worthy results with the GliSODin advanced detoxification formulas ($125; at skinstore.com).

Sandra Bullock used the Advanced Detoxification to prep her skin before the Oscars and Lady Gaga is a fan of the Skin Brightening Formula, which she used before filming her "Bad Romance" video.
