Whether your goal is to look better naked or look better with your clothes on, eating the right foods is key.  According to the book, Look Better Naked! The 6-Week Plan to Your Leanest, Hottest Body -- Ever!, written by Women's Health magazine editor-in-chief Michele Promaulayko, certain foods can help you lose weight, burn belly fat, tone muscle, and make your hair and skin glow.  These nine foods may help you achieve your naked ambitions.

Lean protein-foods. They're important for building muscle mass and controlling craving-inducing, blood sugar dives.  Not all protein sources are created equal though.  These five are particular effective in helping you look better naked.

1) Grass-fed beef. It contains less fat and fewer calories per serving than grain-fed beef.  It's also high in omega 3 fatty acids, (important for heart health and cell metabolism) and conjugated linoleic acid (CLA) to help reduce belly fat and build lean muscle.

2) Skinless chicken breasts. They're an excellent protein source that also contains high levels of Coenzyme Q10.  This antioxidant is thought to assist cell reproduction for healthy skin.

3) Tuna. Canned or fresh, this high-protein fish is easy to prepare, convenient and versatile. Grill up some tuna steaks, add canned tuna to salads and keep some around for easy snacking.  Lay off the high-fat mayonnaise though or you'll have to kick this high-energy food off your look better naked list.

4) Tofu. Not into meat?  This soy-based protein is full of antioxidants for cell renewal, iron for energy, is high in calcium and naturally lowfat.

5) Shrimp. It contains zinc and iron for energy production as well as low fat protein.  The more energy you have, the more you can spend working out, burning fat and building muscle to look better naked.
