Wii Fit U - NO
Donkey Kong - YES
Simple really. Tropical freeze is a fun game. Wii Fit U (and all Wii Fit for that matter) are TERRIBLE at weight loss and working out.
I'm a pretty avid athlete and have have much experience with the Wii Fit family and can tell you that you're much better off working out on your own like normal people.
