Strawberry hulk substitute

I used smoothie kings free smoothie coupon one day and got the strawberry hulk. Now I’m obsessed with it. Come to find out… it’s weight gaining smoothie. I have no desire to gain weight. Is there anything that taste similar but is not weight gaining. I love sweet smoothies specifically. But there is something about the taste of the hulk that I LOVE. Just don’t love the calories tbh.
