I'm losing weight, /fit/, and a staple of my healthy diety is a two fruit smoothie with a half-cup of plain, non-fat yogurt. I would like to switch to French vanilla non-fat yogurt, which would mean an increase of thirty calories and eight grams of sugar.What is the recommended daily intake of sugar? There's no substantial sugar in anything else I eat, save fruit - will switching yogurts make me a fatty?
