This pineapple and strawberry smoothie is delicious and healthy... no doubt it will become one of your favorite healthy smoothies for weight loss quick!I like to add chia seeds to the smoothie, and sometimes I even add in collagen powder. Make sure to see the healthy add-ins in the section above. Special Tip: Get frozen pineapple and peel, slice, and freeze your banana the night before for a super cold smoothie.
