I think it can't be used to lose weight mainly because it is a dehydrated product, and it must have been treated many times during the processing. I'm not sure there must be fried ingredients, but it's too healthy.
The other is fast food, and inevitably there will be some spices. But if you don't eat anything else, it may have a good effect in a short time, but the problems of nutrition and health can't be guaranteed at all.
