We're so used to taking our lattes "skinny" that if you don't, it almost feels as if you're announcing to the coffee shop that you'd like a mug full of fat to go along with that cookie you just ordered. But scientists have started to seriously question skim milk's health benefits. Switching from reduced-fat to nonfat milk hasn't been linked to weight loss, and, in multiple studies, children who drank 82-calorie skim were more likely to gain weight than those who drank the full-fat version. One explanation? Fattier milk increases satiety, decreasing the chances of eating something less healthy later on.
Microchange: Go for reduced-fat, 2 percent milk (122 calories and almost 5 grams of fat), but consider it as part of your snack, not the drink that goes with the snack. Whole milk (146 calories and almost 8 grams of fat) is pretty rich—but still less indulgent than a cup of skim milk and two cookies (239 calories and 9 grams of fat).
