9. Brown-bag it more
You’ll save thousands of calories (not to mention hundreds of dollars) over the course of a year. Consider this: A premade chicken Caesar wrap from a chain restaurant has 610 calories, more than 40% of which come from fat, as well as 1,440 mg of sodium (more than half the recommended daily amount). Make your own with presliced deli chicken breast on whole wheat bread with light mayo and romaine lettuce for about 230 calories. You’ll cut almost 400 calories and about 520 mg of sodium, which leaves room for a side salad and could still add up to a 28-pound weight loss after a year. “When you make and eat your own food, you not only control the quality and portion sizes but also reduce the amount of sugar, salt, and fat that you’re consuming, which can be significantly higher in restaurant fare,” says Ashley Koff, RD, a Prevention advisor and nutrition consultant based in Los Angeles.
