Smoothies can be your best friend or your worst enemy. The size of your smoothie and the ingredients are key to your health and weight management. Smoothies are great because they are full of vitamins and nutrients, they fill you up and cool you down after a workout or during the hot summer. My first suggestion is to order a small (large smoothies are typically too many calories). Be careful what you put in your smoothie, don't use ice-cream or frozen yogurt and stay away from most juices. Instead, use coconut water as a base or a little fresh squeezed orange juice. I personally love using avocado in my smoothies, it adds great nutritional value, makes it creamy and very tasty (don't use too much because avocado is high in calories). Adding things like peanut butter, ice-cream and frozen yogurt can turn what was a healthy choice into a bad choice. Try using avocado, I know it sounds a bit odd, but you will likely love the texture and flavor.
