There’s an old adage you may have heard: “Eat after eight, put on weight.” And maybe you’ve experienced it first-hand: You noticed that eating those late night pizzas and ice cream really packed on the pounds. But was your weight gain due to timing or just the high calorie counts? According to research in the field of circadian rhythms (CRs)—the 24-hour cycle of your body’s biological, hormonal, and behavioral patterns—it seems that when you eat could be just as important to weight gain as what you eat.
Deep within your brain sits a small cluster of nerve cells—a “master clock” of sorts—that’s responsible for orchestrating your CRs. Each biological system in your body works on a different CR schedule, and the master clock keeps all the schedules in sync. For example, CRs influence your body’s production of the hormones that regulate hunger, as well as how your body uses and stores fats and sugar, ultimately influencing your body weight, performance, and overall health. Other hormones, such as the ones that tell you when you’re full, are switched on or off according to a variety of inputs.
The two greatest influences on how well your master clock is able to keep things in sync are light and food. Light tells your brain how much sleep you get (think: eyes closed, less light). Food (smell, taste, and consumption) tells your body to produce a myriad of chemicals. As a result, staying up late at night, working shifts, and eating at all hours of the day and night—whether voluntarily or due to the demands of overseas deployments, training demands, shift-work schedules, and even parenthood—can play havoc with your circadian rhythms.
In an interesting twist, not only do CRs influence hunger and body weight, but excess body fat and/or a high-fat diet may disrupt CRs. This can lead to further weight gain, culminating in a collection of health problems known as “metabolic syndrome.” In the U.S., regular loss of sleep closely parallels the occurrence of metabolic syndrome. In addition, researchers have found that people who sleep less or have poor-quality sleep are more likely to become obese.
What to do? Make a conscious effort to “normalize” your daily routines as much as possible to maintain regular mealtimes. Whether you choose to eat three regular-sized meals or four to six smaller meals a day, space them out through the daylight hours to take advantage of your body’s natural rhythms. Here are some suggestions to avoid eating late at night:
- Try to eat a balanced dinner at least two hours before you go to bed, and take a walk afterwards when possible.
- Sip on soothing herbal tea or flavored water (without sugar).
- Be aware that watching TV (especially food-related ads) can trigger your desire to eat.
- Sometimes it can help to create new nighttime rituals that don’t involve eating, such as light stretching or yoga, taking a warm bath, listening to soothing music, or reading (or listening to) a book.
But if you find yourself up late at night—whether it’s due to a hard day at work, regular shiftwork, or temporary shifts due to jet lag or an infant’s night feedings—resist the urge to snack out of boredom or to “keep your energy up.” Shift workers should pack or purchase a healthy meal to eat during their work hours—one that includes lean protein and complex carbohydrates such as whole grains, fruits, and vegetables. Eat early in the shift if possible, so you’ll have the energy you need to think and move efficiently. Travelers and parents should look for healthy snacks that follow a similar pattern. And try to limit coffee, tea, and other sources of caffeine to just two to four servings a day.
Of course, eating is just one half of the CR equation. Getting enough sleep is important too, so read HPRC’s overview for great tips on how Warfighters can improve their sleep.
Holiday parties provide opportunities to relax and enjoy good food and good times with family, friends, and colleagues. But they also can derail your weight and fitness goals. Buffet tables laden with calorie-rich treats and beverages can weaken the resolve of even the most committed folks. To keep yourself on track, remember these tips:
- Never go to a party hungry. Eat a protein-rich food before you go. Protein foods tell your brain that you’re satisfied and help you avoid overindulging. Low-fat milk or yogurt or a handful of nuts are great choices.
- Follow the MyPlate strategies for filling your party plate: Fill half your plate with fruits and vegetables then fill the rest with whole grains and lean protein such as fish or chicken.
- Choose wine over fancy mixed drinks or beer, and be sure to drink in moderation: one drink for women and two drinks for men. Sip slowly to make your drink last through the evening.
- If it’s a potluck, you really are in luck. Offer to bring a healthy salad or entrée, and fill your plate with your own delicious creation.
- Don’t waste your calories (and taste buds) on desserts that you don’t absolutely love. Choose your favorite and then share it with a friend. You’ll eat slower while you and your friend chat, and cherish the moment as much as the sweet!

It’s the New Year! If you’re already despairing about resolutions, keep in mind that making small changes in behavior that fit easily into your lifestyle are good options for family health and weight loss over time. For one month, try choosing three small habits to focus on changing that you can apply to any situation, whether you’re at home, overseas, or travelling. Try setting up email or calendar reminders if that helps you, or put up tangible reminders such as sticky notes around your house. To get you started, here are some ideas:
- Keep unhealthy foods such as potato chips, cookies, etc. out of sight so they are less tempting.
- Put down your fork and knife between bites.
- Portion out “snackable” foods that come in large bags/containers into smaller one-serving containers, so you don’t keep dipping in.
- Choose water over soda.
- Keep fresh fruit on hand to replace fatty, high-calorie snacks.

Preventing obesity should begin at an early age, because children who are overweight often become obese as adults. And while many of us know that we need to eat right and exercise, there are also risk factors that we are born with that we can’t change. Now you can calculate your child’s risk of developing obesity with an online calculator.
The calculator was developed by a team of researchers who looked at a number of well-known biological and social risk factors for developing obesity. They were able to boil down their findings to six simple factors that provide a reasonably accurate probability of whether a child will develop obesity:
1) The body mass indexes (BMIs) of both parents. (HPRC has a link to a calculator you can use to calculate BMI.)
2) The number of people who live in the house.
3) What kind of work the child’s mother does.
4) Whether the mother smoked during her pregnancy.
5) The birth weight of the child (in kilograms). (To convert pounds [lb] to kilograms [kg], multiply pounds by 0.45359237.)
Living a healthy lifestyle is beneficial for everyone, but tools like this can help you determine whether your child is particularly at risk for becoming an obese adult, so that you can make important health changes early in life. For ideas to help your family be physically active and healthy, check out this HPRC Healthy Tip as well as the family physical fitness and family nutrition sections of HPRC’s website.
The Institute of Medicine (IOM) just released its recommendations for obesity prevention in response to the rising obesity rates in the United States, a problem that affects the military. IOM has also developed an interesting graphic that shows where significant problems lie and how we can change our communities to help solve them. See the graphic and download the free report here.
Looking for programs to help manage your weight? The Human Performance Resource Center just posted its new “Fighting Weight Strategies” page, where we have compiled a list of programs and resources, arranged by service, for maintaining overall health and body weight.

Overall healthy food choices may help prevent long-term weight gain. A recent study in the New England Journal of Medicine found that potato chips, other forms of potatoes, sugary drinks, and both processed and unprocessed meats can contribute to long-term weight gain. Gradually including more vegetables, whole grains, fruits, nuts, and yogurt in one’s diet contributed to less weight gain. Other creeping changes that affect long-term weight gain are physical activity, watching TV, and sleep duration. Read more about the study details in an article from Medical News Today.
Body weight may be used as a measure of overall health by calculating your body mass index (BMI) and may also be used as an indicator of your health risks, particularly if you have more body fat than recommended. Read this answer from the American Council on Exercise to learn more about your ideal body weight. The Army’s Hooah 4 Health website also has online calculators for body mass index and optimal body weight.
