Then I started wondering how low calorie they could be . I found a recipe for 40 calories , so of course ... I had to try it . Unfortunately ( or rather fortunately , I suppose ) , my brother has basically NO ingredients for ANYthing . So I had to substitute nearly everything in the recipe because there were no eggs / vegetable oil / applesauce , butter / margarine , salt , or baking soda / self - rising flour .

Question: Why is the speaker interested in find low calorie recipes ?
Answer: They are on a diet and are trying to limit the calories that they consume in a given dayThey are on the marketing board of a food manufacturer and are trying to create low calorie treatsThey are trying to determine the exact amount of calories in every ingredient for researchThey are doing a science project to determine if calories and taste are entirely related
