Question: how many calories are in a jello cup?
Answer: Jello has long been a staple of many diet plans, as it's low in calories and fat-free. However, this doesn't necessarily make it healthy. One serving (21 grams of dry mix) has 80 calories, 1.6 grams of protein, and 18 grams of sugars — which is approximately 4.5 teaspoons ( 2 ).
