Like "It is impossible to give you a simple answer. How many carbs you should eat is influenced by several factors such as your height, weight, sex, age, and activity level. To determine how many carbs you first need to know how many calories are right for you and that again is different from individual to individual based on your personal metabolism rate. I can give you a fairly simple way to determine it. First, determine how many calories you need per day. You can do this by accurately recording your daily calorie intake and watch your scale. When your weight is stable that is the amount of calories you need to maintain your weight. If you want to lose weight reduce the calories consumed by 500 for each pound you wish to lose each week. Once you have your ideal calorie consumption you can determine the proper amount of carbs. In my opinion it is a mistake to only focus on carbs. I use a 20-50-30 PCF ration and that works very well for me. PCF ratio is the ratio of calories from Protein, Carbohydrates and Fats I consume at each meal. That is a sound bite answer that needs to be expanded a bit. 20% calories from good protein sources such as Lean chicken breast, fish, beans, spinach, and other good protein sources. 50% calories from low glycemic Carbohydrates. Contrary to the old information still promoted by ADA there is a huge difference in how different carbs raise blood glucose. 30% calories from good fats. The sound bite answers on fat are also very misleading. Too often, all fats are lumped into the same category. There are over 48 varieties of dietary fat. These fats cover the range from good to bad. Some are very bad and others are essential for good health. It takes work to get it right. Maybe it is the simple answers that got us in trouble in the first place. The biggest contributing factor to the ever increasing rate at which Americans are being diagnosed as type 2 diabetic is our extremely bad North American diet based on convenience and highly processed inflammatory foods.
