Now I'm trying to lose some weight, so I practically don't eat fast food. I think that fruits help me lose weight very well, so now I actively buy and eat them. By the way, I like durian and I can recommend durian delivery service if you want to try something new and different too. But I immediately warn you that not all people like durian.
