Orange juice adds a lot of sugar to a NutriBlast without any fiber - while water adds no added sugar. This can potentially cause a rapid spike in blood sugar which can leave you feeling jittery and a higher chance of cravings later in the day (when your blood sugar heads back down). You want to be sure that your blood sugar is well managed so a balance of sweet whole fruits with veggies that are fiber rich along with a nice little boost of protein can help keep it stable. Maybe start with 1/2 orange juice and 1/2 water then slowly reduce the amount of OJ. Or try another liquid option like unsweetened almond milk or 1/2 coconut water and 1/2 water to add flavor w/o a lot of added sugar.
