Red Vines

red varieties are fat free, but there is sugar. I do not understand, I thought sugar converted into fat? So how is it "fat" for free?

He is fat because there is no fat in the red vines. It's just sugar, colorings and flavorings.

However, there is fat in chocolate to red varieties are different than the chocolate fat.

There is a difference between fat mass and fat in foods. Many food products are not fat, but eat them (and therefore eating too many calories) may lead to the addition of body fat.
