First-Year Food

Most students tend to eat more than they did when living at home, sampling everything and snacking late at night. Eventually, many gain weight (the "freshman 15").

Studies show that students on average gain 3 to 10 pounds during their first 2 years of college. Both girls and guys do more maturing during their college years, so some weight gain is to be expected. But people who really pack on the pounds may become overweight or obese, increasing their risk of developing weight-related medical problems like high blood pressure and diabetes. And some students may resort to excessive dieting or other unhealthy eating behaviors when they see the number on the scale creeping up, or because they feel stressed.

To help you maintain a healthy weight, eat normally and at regular intervals — usually three well-balanced meals and maybe one or two healthy snacks — at the same times each day. That way, your body knows what to expect. Pay attention to your inner signals and eat when you're hungry and stop when you feel full. Watch portion sizes and try to resist trips back to the buffet for additional servings.

But chowing down when you're bored, munching because your roommate has pizza (even though you've already had dinner), or snacking on chocolate simply because you're stressed, means you are overriding your body's natural signals. This tends to lead to more chaotic eating and weight gain.

So now you know when to eat, but how about what to eat? Eating right is all about balance. You'll want to eat foods from each group every day. If your meals include too many items from one food group, it's at the cost of nutrients from another. Eating from many food groups doesn't just give the body a well-rounded diet — it satisfies your mind's craving for variety, too. So don't worry about eating an occasional candy bar, just don't use it to replace a well-balanced dinner.

A final note about food: It's tempting to pull all-nighters with the aid of caffeine. But too much caffeine can cause anxiety, dizziness, headaches, and the jitters. Caffeine can also interfere with normal sleep. And you can become dependent on caffeine with as little as 100 milligrams a day, which means you may experience withdrawal symptoms like headaches and irritability if you don't get your daily fix. Most people know caffeine is in coffee, but watch out for it in energy drinks, soft drinks, iced teas, and over-the-counter medications.
