Really worried about my girlfriends health. she is on diet to lose weight and kind of weak. should i give her candy?

Avoid The Candy: I don't like the phrase : " on a diet", because going " on " implies going "off". Actually a permanent lifestyle change should be her goal. It is also best to know why someone gained weight in the first place before a solution is applied. She could be weak for any number of reasons, but giving your girlfriend candy is not really a good idea. Find out why she is "weak" if possible.
