This one is tough for me... but I think that it all boils down to the yogurt that you choose...

Had 2 egg whites and 1 yolk w/a tomato, cauliflower and onion hash by noon and took my vitamins. Also had plenty of water. Hopefully after my Fit Test... I'll have my protein shake and one more meal before the rosary tonight. Wish me luck folks...

5. Yogurt

Eat It!
Get ready to show off your pearly whites! Spooning up yogurt can help keep your grin gorgeous. "It has calcium and phosphorus that can strengthen tooth enamel and protect your teeth from cavities," says Drayer. What's more, varieties such as Greek-style yogurt are high in protein, which is an essential nutrient for the production of collagen, a fibrous substance that keeps your skin youthful looking, according to Dr. Wu. Score more daily dairy by replacing regular sour cream with fat-free plain yogurt in recipes for salad dressings.

Apply it!
Yogurt contains lactic acid, an alpha hydroxy that's great for sloughing away dead skin cells and unclogging pores, says Dr. Wu. She suggests using full-fat plain yogurt as a mask: Apply a thin layer to clean skin and leave on for 10 minutes before rinsing. You can also whip it into a protein-rich hair mask, says Rhys. Whisk together 1/2 cup full-fat yogurt, 3 tablespoons honey, and 1 egg yolk. Apply to hair, put on a shower cap, and wait 15 minutes before rinsing and washing as usual.
