The argument is not valid because the two premises do not logically lead to the conclusion. Just because all candy is fattening and all candy is delicious, it does not necessarily mean that all fattening food (which includes more than just candy) is delicious. This can be seen by drawing Euler circles for "candy" and "fattening food" - while there is overlap between the two circles for "candy," the circle for "fattening food" extends beyond just "candy" and includes many items that may not necessarily be delicious.
