Just a few years ago most people probably would have had no idea that something called Greek yogurt even existed, but with increased interest in eating healthier and optimizing digestive health, Greek yogurt has been appearing in TV commercials and on supermarket shelves at an ever-increasing rate. Variety is a good thing and since a 20-year study by Harvard University found that yogurt is the single best food to eat for those wishing to lose weight, you can probably find a flavor that pleases your palate and helps you lose weight at the same time. Greek yogurt packs an additional nutritional punch by having twice as much protein and less sugar than regular yogurt.
