How should I track Yogurt, Greek, plain, lowfat?
Yogurt, Greek, plain, lowfat is a good source of protein. The best way to track Yogurt, Greek, plain, lowfat is by weight, not volume. A 200 g serving of yogurt or cheese varies in density between brands and fat levels, so the same portion can differ by 20–40 calories. Research shows people underestimate calorie-dense dairy portions by up to 50% when eyeballing (Almiron-Roig et al., Appetite 2013). A kitchen scale keeps things honest. Also check whether the label lists values for the product as sold or as prepared — some powdered or concentrated dairy products show very different numbers once mixed.
