Diet jellies are typically marketed as low-calorie or reduced-calorie snacks or supplements that can be consumed as a part of a weight management or diet plan.

Diet jellies usually contain a combination of ingredients that may include water, gelatine or gelling agents, sweeteners (often artificial sweeteners or sugar substitutes), flavourings (in this case, strawberry flavour), and sometimes added vitamins or minerals.

One of the primary features of diet jellies is that they are low in calories compared to regular jellies or desserts. This is often achieved by using artificial sweeteners or sugar substitutes to provide sweetness without the calories found in sugar.
