I really wanna loose weight fast i work out 4 times a week. volleyball practice and i would want to go on a diet. which would you suggest?

Eat 3 meals a day: Simple sugars and processed carbs should be avoided or limited. This includes any flour product. The fine grind makes absorption quick, and spikes your blood sugar which increases Insulin and promotes weight gain. Good fats such as olive oil and coconut oil are fine in sensible amounts. Eat a rainbow of organic vegetables and just enough protein.
