Both are good staple foods for losing weight. Personally, if you choose one of the two, it should be taro. There will be less sugar. However, you can also eat two crossed ones, always eating the same, which is easy to get bored.

But you can't just eat these. You can usually eat some vegetables (just scalding water) and fruits. If you want to look better, you can stew some tremella and jujube soup every day to lose weight ~ ~
