So-called “diet” foods can make you fat. How? They are loaded with sugar. To make processed diet foods lower in calories, much or all of the fat is removed, but sugar is added–sometimes in great quantities–to make them taste better. And you really have to pay attention to know that because the sweet ingredients are camouflaged under other names to give the impression that the food is healthy. That’s the word from University of Georgia researchers, who determined that these sugar-laded “diet” foods can actually cause you to gain weight.
