Not planning ahead is one mistake nutritionists agree causes weight gain. You can avoid the temptation of eating countless calories at the local cafe by packing a lunch from home. When made right, salads are great because they're full of fiber and protein to satisfy hunger and keep blood sugar steady. Prepare a salad in a mason jar like this roasted sweet potato and quinoa salad, or make extra for dinner and bring along this sesame ginger quinoa salad.
Whatever you choose, it's much easier to add up the calories on lunches you pack from home. And when it's made the night before, there's no morning stress or forgoing it altogether because you don't have time. Go the distance and pack snacks, too, and put everything in the actual lunch bag, so when it's time to head out for the day, you can just throw in an ice bag, grab it, and go.
