That depends. Many people can get away with eating less bread in their diets because they are very inactive and don't need that many carbohydrates (carbs)to support a sedentary lifestyle. Athletes however, need a greater amount of complex carbs and may need bread (along with pasta, grains, etc) to meet their carbohydrate needs.
If you tend to overeat bread cutting back may help you shed excess pounds. Focus on getting carbs from fruits, veggies, and whole grains like oatmeal, brown rice, etc.
