No matter how much time you spend reading nutrition labels and eating healthy, one of the biggest factors to any successful nutrition plan is still to exercise regularly. A strong nutrition plan can't make up for a lack of exercise and no matter how healthy your diet plan may be, you won't see the full effect of it until you begin exercising regularly.
Not all carbs are created equal. A fascination with low-carb diets has a lot of people eliminating all carbs from their diets. This is a mistake, a key to good nutrition is carbohydrate intake. Your brain and body needs carbohydrates every day in order to function at a maximum level. Complex carbohydrates, especially those rich in fiber and whole grain, keep you full longer and help you to avoid snacking.
