Shine offers some great celebrity diet secrets. The secrets are centered around strategic eating and plenty of water.

1. Plan your meals. When you don’t plan ahead, you are more tempted to snack on junk foods.

2. Drink ten 8 ounce glasses of water daily. It sounds like a huge amount, but remember water curbs hunger pains.

3. Add flavor to your meals not in the form of salt but with herbs or lemon. Grilled fish doesn’t have to be boring.

4. Eat good fats. For example, nuts and olive oil are great sources of fat.

5. Make each meal balanced. Each meal should have a balanced ratio of 30% protein, 40% carbs and 30% good fats.

6. Speed up your metabolism by eating five small meals: breakfast, lunch, afternoon snack, dinner bedtime snack. The emphasis is on small, the food on your plate should not be larger than your hand.

Are you always starving before meals? Curb your hunger before so that you don’t overeat at dinner by snacking on 20 almonds before each meal.
