How Eating Sugar Contributes to Weight Gain
Sugar contributes calories and taste to foods, but not nutrition. Ferrari said this is why it's often referred to as empty calories. "Typically, foods that are high in sugar offer little nutritional value and displace other foods that provide vitamins, minerals, fiber, protein, and healthy fat." This means that when you reach for an afternoon cupcake, you're missing out on the protein, fiber, and vitamins you'd get if you snacked on yogurt and fruit or hummus and veggies instead.
Stahl added that "too much added sugar can crowd out lower-calorie nutritious foods from a person's diet, can lead to weight gain and obesity, and impact metabolism." Ferrari agrees and said, "Cutting sugar is a great way to lose weight and improve your overall diet quality."
