That whole grapefruit diet that your mom tried way back when? She may have been on to something: Experts say this vitamin C-packed fruit helps reduce insulin levels and steady blood sugar levels, which, in turn, helps boost metabolism and helps you stay full longer (so you end up eating less). Did we mention that it also acts as a diuretic? So if you're holding onto any holiday bloat, adding a bit of grapefruit to your diet could do wonders. Now, we're not suggesting you subsist on grapefruit alone, but what’s so hard about eating some grapefruit along with your Cheerios in the morning or tossing some slices into a salad?
