Direct costs to attend the university include tuition & fees and room & board. As an example, the direct costs for a full-time, undergraduate resident student who lives on or off campus are $15,688.
In this case, your dietitian or diabetes educator should give you an idea of how many carbohydrates you should eat at each meal and snack. A general rule of thumb is to limit your carb intake to around 30-60 grams at meals and 15-30 grams at snacks, although this varies greatly.
But as a rule a diabetes instructor will tell you 45-60 gms of carbs per meal and 15-30 for snacks. 3 meals a day and 3 snacks a day. If you are trying to lose weight I'd stick to the low end of that range and add exercise.
