That’s NOT fruit!

Making healthy food choices is never easy. It is made more challenging by the fact that some foods that appear to be a smart choice may be less healthy than you think.

This is the topic of my Health & Fitness column in the Aiken Standard this week. It is a topic I have addressed in the past that is still relevant today. Specifically, regarding what my kids picked for breakfast this morning! This shouldn’t be a surprise, since many foods that look healthy, but aren’t are breakfast foods marketed to children.

Often, prepackaged fruits and vegetables contain added sugar, fat, or salt, making them less healthy than eating them fresh. Consumption these foods can also make it less likely that people—especially children—will eat fresh fruits and vegetables when they are available.

The problem is that these foods may look like fruit. They may even contain real fruit juice. But many drinks and snacks–especially for kids– that look like fruit are really candy in disguise.

Here are a couple of examples of foods that may appear to be healthy but, upon closer examination, turn out to be less nutritious than we might think.

Fruit snacks: These gummy fruit treats are a favorite among kids. If you check the package you will probably see that they contain real fruit or fruit juice, so they must be healthy, right? While there is variation among different brands, in most cases these snacks contain little, if any, actual fruit. If you read the ingredients you will see that they do contain lots of added sugar, meaning that many of these snacks are essentially candy. In fact, if you compare some brands of fruit snacks with something that is easily recognized as candy, such as gummy bears, you will see that they have a similar sugar content.

Fruit drinks: Not everything that looks like fruit juice is actually juice. Take Sunny D for example. This popular orange drink contains mostly sugar and water—and only 5% juice. By contrast, real orange juice contains fewer calories and more vitamins per serving. In fact, if you compare the ingredients and nutrition information, Sunny D is essentially orange soda without the bubbles!

There are two problems with this. First, some foods that appear to be healthy because they either claim to or actually do contain fruit are actually less healthy than we might believe. Considering that fruit snacks and fruit drinks are likely to be consumed as alternatives to real fruit juice or a piece of fruit as a snack, these foods could lead to poor nutrition. This is especially true in children.

Second, sweetness is one of the most important tastes we respond to. Consuming food and beverages that are flavored like fruit but are actually much sweeter may make real fruit less palatable. Again, this is especially true for children who may develop an expectation that strawberries should taste like strawberry-flavored fruit snacks or that orange juice should taste as sweet as Sunny D. These kids are likely to prefer the sugar-sweetened version over the real fruit. Since these sugar-sweetened “fruits” tend to be higher in calories, consumption of these foods is one contributor to childhood obesity.

This isn’t just the case with fruit. Adding salt and sauces to vegetables makes them more flavorful, to the point that many of us don’t eat plain vegetables very often. The majority of potatoes are consumed in the form of French fries, loaded with both fat and salt. This has changed how we expect potatoes to taste so that now we typically eat baked potatoes “loaded” with butter, sour cream, cheese or bacon. When was the last time you ate a plain baked potato?

But there are some simple steps you can take to get back to eating real fruit and vegetables. Look for 100% fruit juice or, better yet, a piece of fruit instead of fruit-flavored drinks. Instead of sugar-sweetened fruit snacks, try dehydrated fruit. Cut back on the salt, butter, and other toppings you add to vegetables or purchase frozen vegetables without added sauces.

Subway’s identity problem (and why it matters).

If you are looking for a healthy place to eat lunch, chances are you will think of Subway. More than any other fast food restaurant, Subway has developed a reputation for being a healthy choice, consistent with losing weight and an active lifestyle. While you can get healthy food at Subway, you may end up eating a meal that is similar to traditional fast food in terms of calories, fat, and sodium.

This “identity problem” — Is it a healthy option to regular fast food? Or just an alternative to fast food? —  is the topic of my Health & Fitness column in the Aiken Standard this week.  This matters, of course, because you may well be fooling yourself into thinking you are making healthy choices when you aren’t.

Subway has long been thought of a healthy alternative to traditional fast food. This is largely due to a menu that has fresh-looking sandwiches rather than burgers and fries. Food at Subway looks healthy. This image is enhanced by a marketing strategy that associates Subway with health and wellness, something they seem to do better than any other fast food chain. Advertisements featuring former Olympians were abundant during the winter Olympics television broadcasts and the continuing association with Jared Fogle, who lost nearly 250 pounds by drastically changing his diet—including eating at Subway—and becoming more active strengthen this image.

The Subway menu does include several sandwiches designated as Fresh Fit choices that are low in fat and calories and could contain a full serving of vegetables. If you read the fine print you will see that this is true if you order a 6-inch sandwich on plain bread with meat and veggies, but no condiments or cheese. Adding mayo, sauces, and cheese or substituting another bread will increase the calories and fat in the sandwich. But, if you make smart choices, select a healthy side such as apple slices, and have water, unsweet tea, or another calorie-free drink, you can get a healthy, low-calorie meal.

However, that does not mean that all of the sandwiches at Subway are good choices if you want limit calories or fat. One of the sandwiches featured currently is the Fritos chicken enchilada sandwich, which is served exactly as it sounds: shredded chicken topped with enchilada sauce and Fritos chips. But if it comes from Subway it must be healthy, right?

Wrong! If you look at the nutrition information you will find that this sandwich has 580 calories, 26 grams of fat (which account for 40% of the calories), and 1170 milligrams of sodium (nearly half of what you should get in a whole day). The best traditional fast food comparison is the Big Mac at McDonald’s, which has 550 calories, 29 grams of fat, and 970 milligrams of sodium. Considering that many people eat at Subway in an effort to avoid the fat and calories of fast food, this would not be a good choice.

The point is that while you can get a healthy meal at Subway, many menus items are as high in fat, calories, and sodium as food at other fast food restaurants. The image that Subway has carefully cultivated likely conceals this fact, leading people to think they are eating a healthy meal when, in reality, they are not. It is also possible to get a meal at McDonald’s and many other fast food restaurants that is nutritionally similar to the healthier sandwiches at Subway.

This is a good lesson, since menus at many restaurants include a “healthy choices” section. Keep in mind that food that appears to be healthy may not be and that a restaurant typically thought of as a poor choice may have healthy menu items. The trick is to check out the nutrition information and make smart choices.

Sports Science at the Winter Olympics

So, the 2014 Winter Olympics wrapped up with the closing ceremony yesterday. If you have been watching the Olympics you have seen some incredible performances. The competitors are among the fittest and most highly trained athletes in the world, both in terms of laboratory measures of fitness and in subjective evaluations of skill. Competing in the Olympics requires years of focused, intense training and some good luck.

In my Health & Fitness column in the Aiken Standard this week I take a look at the  physiology that goes in to training for and competing in the Olympics.

First, let’s look at the fitness. This is most evident in the endurance events like cross-country skiing and speed skating. The key to performance in long-duration events like these is for the muscle to contract repeatedly and forcefully without fatigue. In order to do so, the muscle must have a steady supply of oxygen and nutrients. These nutrients are delivered through the blood, which is pumped to the muscle by the heart. The muscle takes up and uses these nutrients to produce ATP, the form of energy used by the muscle.

After months and years of endurance training the heart gets bigger resulting in the ejection of more blood to the muscle. Within the muscle there is an increase in the number of capillaries, the small blood vessels that deliver blood to the muscle, and mitochondria, the part of the cell that produces most of the ATP. Together, these adaptations allow the muscle to produce more ATP without fatigue, allowing the athlete to sustain a higher intensity (skiing speed, for example) for a longer time without fatigue.

How fit are these athletes? In the laboratory we measure VO2max, the maximal rate at which oxygen can be used by the muscle to power exercise, during intense exercise. While we don’t have test data on most Olympic athletes, cross-country skiers tend to have the highest VO2max values, followed closely by distance runners and cyclists.

While all Olympic athletes are all very physically fit, other events rely more heavily on skill including figure skating and freestyle snow boarding. For example, in figure skating completing a triple axel involves leaping into the air, spinning three and a half times, and landing backwards. On a 4 mm wide blade. On ice. Or think about the triple cork 1440, a snowboarding trick that involves flipping three times in the air while doing four 360-degree turns.

The athletes who are able to successfully complete these maneuvers have practiced for years to develop the skill and confidence needed to perform them consistently in competition. These are some of the most obvious displays of athletic skill, but all events require good technique. The development of skill in addition to fitness is the main reason why athletes specialize in one area and you don’t see people competing in both downhill skiing and speed skating, for example.

Of course, there is a psychological aspect to Olympic performances. The motivation to put in the training time alone is remarkable. Even more impressive is the ability to focus on an event despite the distractions of the crowds, media, and pressure of competition. This combination of physical and mental preparation is rare—as rare as Olympic gold medalists!

The training and preparation followed by bobsledders provides a good model for what goes into creating an Olympic athlete.

But is training alone sufficient for Olympic-level performance? Could anyone who trains enough make it to the Olympics? The answer is no, because there is another important factor in athletic performance—luck. Luck refers to genetics, which determine potential for attributes like heart size and muscle characteristics. As much as 50% of performance in some events is attributed to genetics. One sports physiologist famously answered the question, “How do I become an Olympic champion?” with “pick the right parents!”

There is more that I am missing (on purpose, because I have a word limit in my column). One additional key factor is nutrition. Despite what Subway would have you believe, Olympic athletes don’t really eat a lot of sandwiches with Fritos on them. In fact, this is a good overview of what US Olympians eat to fuel their training and competition.

Even though most of us will never become Olympic champions we can still experience many of the same benefits of training. All athletes train to develop strength, endurance, and flexibility, which is exactly what we should do, too. And those attributes will help us perform better at work (and play) and help us live a longer healthier life. It will also help us appreciate the training, dedication, and good luck that the athletes bring to the Olympic games.

Reducing your risk of heart disease

February is Heart Month, an ideal time to assess your risk of heart disease and take steps to improve your health. This is important because heart disease, sometimes called coronary artery disease, is the leading cause of death among adults in the United States. It is responsible for nearly 600,000 deaths each year, mostly from heart attacks. Millions more are at increased risk because of certain biological and behavioral risk factors.

Identifying your personal risk for heart disease and making efforts to improve your heart health is the topic of my Health & Fitness column in the Aiken Standard this week.

Some of these risk factors cannot be changed, such as age, sex, and family history, while others can be altered to reduce risk. These modifiable risk factors include smoking, high blood pressure, high cholesterol, diabetes, obesity, and physical inactivity. While your doctor can play an important role in treating these conditions, there is much you can do on your own to improve your heart health.

The first step is to get a good assessment of your heart health. If you haven’t done so recently, you should see your doctor to have your risk factors evaluated. This includes tests for blood glucose and blood lipids (including total, LDL, and HDL cholesterol and triglycerides), measurement of your blood pressure and body weight, and an assessment of other health factors such as your family history, whether you smoke, and your level of physical activity.

The next step is to treat the risk factors that you have. Depending on the severity and your own personal health history your doctor may prescribe medications to lower your blood pressure, blood glucose, or blood lipids. These medications are most effective when combined with lifestyle changes including good nutrition, exercise, and weight loss. In some cases, poor diet and lack of activity can counteract the beneficial effects of these drugs. Furthermore, these healthy habits may help you reduce the dosage, and limiting the side effects, or stop taking the medications altogether.

The other risk factors—obesity, inactivity, and smoking—really must be treated through lifestyle management. While there are medications that can help with smoking cessation and weight loss, being successful requires making lasting behavior changes. These habits can be difficult to change, and many people have tried before without success. Keep in mind, though, that everyone who is successful at quitting smoking, losing weight, or sticking to an exercise program has experienced his or her share of difficulty. The difference is that those people kept trying until they were successful. You can be successful, too.

Even small changes can have a big impact. Take exercise, for example. The benefits of as little as 30 minutes of physical activity per day are well established and impact heart disease risk in a multitude of ways. Physical activity helps with weight control, lowers blood pressure, improves blood lipids, and prevents and treats diabetes. Think of this as a great health “deal.” By modifying one risk factor—inactivity—you can also promote beneficial changes in four others—obesity, hypertension, high cholesterol, and diabetes. There is no other treatment, drugs included, which can have such a broad impact on reducing heart disease risk!

Of course, there are steps you can take beyond becoming more physically active to reduce your risk of heart disease. The list of beneficial changes you can make to improve your heart health is long, but keep in mind that even small changes can add up to a big benefit. 

Knowing which risk factors are most concerning can help you and your doctor make effective treatment decisions. Quitting smoking, increasing your physical activity (and reducing sedentary time), and eating a healthier diet can lead to improvements in heart disease risk factors and reduced heart attack risk. The best news is that these same changes can also reduce your risk of other serious health problems including many types of cancer, stroke, and lung disease.

 

 

What is a healthy breakfast?

Everyone knows that breakfast is the most important meal of the day, right?

Eating a healthy breakfast provides energy to start the day, can reduce hunger to prevent overeating later in the day, and is important for attention and learning, especially in kids.

But what is a healthy breakfast? This is the topic of my Health & Fitness column in the Aiken Standard this week.

 Unfortunately, there is no specific answer to that question. I think most experts would agree that a good breakfast should include a combination of carbohydrates, protein, and even some fat but be low in added sugar. These broad guidelines suggest that there are many ways to create a healthy breakfast, even if it doesn’t include traditional breakfast foods.

Instead of making a list of all the foods that could be part of a healthy breakfast, I took the opposite approach and made a list of foods that shouldn’t  be part of a healthy breakfast. The idea being that if your breakfast contains these items,  it could likely use some improvements. And if you avoid these foods, your breakfast can’t be all bad.

So, here is my list of foods that almost certainly aren’t part of a healthy breakfast:

1. It has frosting on it.

I think everyone would agree that foods that are frosted are better classified as dessert than breakfast. That said, from donuts to Pop Tarts to breakfast bars, many unhealthy breakfast foods are covered with a layer of frosting.

2. One of the ingredients is marshmallows.

Just like frosting, breakfast foods that contain marshmallows are probably better choices for dessert. Marshmallows are found in cereals, granola bars, an other packaged foods that are almost always high in added sugars beyond the marshmallows.

3. It is topped with whipped cream.

A fruit smoothie can be a healthy breakfast. But a fruit smoothie topped with whipped cream is likely closer to a milkshake as far as sugar and calories are concerned. The same goes for coffee drinks. A mocha-caramel-latte with whipped topping may contain coffee, but it also has far more sugar, fat, and calories than you might expect.

4. It contains chocolate.

Research shows that eating chocolate may have health benefits. But the research involves consuming small amounts of dark chocolate, not chocolate donuts or chocolate-flavored cereal. Again, save the chocolate for dessert.

5. You are eating it in your car.

More specifically, you got the food while you were in your car, which means it likely came from the drive-through window at a fast food restaurant. Fast food is just as poor of a choice for breakfast as it is for lunch or dinner.

Of course, this is a work in progress and there are certainly some exceptions. And there is nothing wrong with treating yourself to a chocolate frosted donut once in a while. But if your daily breakfast includes items from this list, you could benefit from a breakfast makeover, and this list should help you avoid many unhealthy choices.

Honesty is the best policy

Being honest about your health is the topic of my Health & Fitness column in the Aiken Standard this week.

Have you ever justified your weight by saying you are “big-boned?” What about your eating and exercise habits? How often do you really eat out? How many days did you actually get to the gym last month? Are you being honest with yourself when it comes to your health? And are you asking others to be honest with you?

Being honest with yourself is essential for initiating health behavior changes and setting good goals. For example, someone who tells themselves they need to lose “a few pounds” may really need to lose much more and may not take their weight loss as seriously as they should. Convincing yourself that you are doing more exercise than you really are may mean that you won’t see the fitness or weight loss results you were expecting.

This type of self-deception is easy to do. Take body weight for example. The current standard for determining if you are at a healthy weight is body mass index (BMI), calculated from your weight and height (kg/m2). It requires a bit of math, so using a mobile app or online calculator is a good idea. A BMI between 18.5 and 24.9 is considered normal, 25-29.9 is overweight, and if your BMI is 30 and higher you are classified as obese. To put this in perspective, a BMI of 30 is equivalent to about 25–30 pounds of excess fat.

Let’s say your BMI puts you in the obese category, suggesting you should lose weight. But then you think about an article you read about how BMI isn’t accurate because you can be considered obese if you have excess muscle, not fat. And then there was the story on the news suggesting that it is okay to be obese as long as you are physically fit. So, maybe you don’t need to worry about your weight!

See how easy it is to tell yourself that you don’t really need to lose weight. In reality, BMI is an accurate method of assessing your body fatness; the inaccuracies reported in the news almost always involve athletes or people with lots of muscle mass developed through physical labor. Be honest…is that really you? It’s also true that people who are fit and fat can be healthier than people who are thin and sedentary, but it requires a lot of exercise to reach that level of fitness. Again, are you really that fit?

Probably the best test is to take a good look in the mirror and be honest about what you see. Try to “pinch an inch” of fat around your belly. One inch isn’t necessarily a problem, but take notice if you can pinch a handful of fat. Measuring your waist circumference (or looking at your pants size) can give you the same information. People who have a high BMI because of extra muscle, like athletes, have thin waists. If your waist circumference is greater than 35 inches (for women) or 40 inches (men), you have excess fat.

This honesty also applies to others, including your doctor. Many physicians are reluctant to discuss weight and weight loss with their patients, and many patients don’t want to hear what they interpret as a personal attack. Don’t be one of those patients! Ask your doctor for an honest assessment about your weight and the impact it might have on your health.

This is a real problem. According to one report, only 39 percent of obese people surveyed had ever been told by a health care provider that they were obese.     To help combat this problem, the American Medical Association has developed resources to help physicians better communicate with patients about their weight.

Making changes to diet and activity habits is a difficult process, to be sure. Telling yourself that you don’t need to make them only delays getting started and can lead to poor health in the meantime. When it comes to your health, honesty is the best policy!

Eat smart, move more, chill out

The goal of being “more healthy” is a good one, but can include an almost endless list dietary, activity, and other behavioral changes. Some people may feel overwhelmed and unsure of where to begin. Furthermore, there is a perception that you have to implement all of the changes simultaneously or follow a complicated diet or exercise program in order to see results.

But it doesn’t need to be this way. My Health & Fitness column in the Aiken Standard this week outlines a few simple guidelines that have the potential to lead to significant improvements in health, fitness, and wellbeing. Not only are these things you can implement right now, but they are scalable, so the more you do, the bigger the benefits.

1. Eat smart.Healthy eating isn’t necessarily about eating less or avoiding certain foods, it’s about making smart choices when you shop, cook, or eat out. Many problems with the typical American diet probably have to do with the fact that we tend to eat heavily processed, calorie-dense foods. The major difference between what we eat now and what most people ate before the current obesity epidemic is the processing our food undergoes.

You can eat smart by focusing on eating real food—fresh and minimally processed plants and animals—instead of the processed and pre-packaged food that is so common in restaurants and in meals we eat at home. That isn’t to say that all processed food is necessarily unhealthy, but it would be wise to shift the balance toward more real food.

This isn’t necessarily new advice…it was featured on the cover of a popular book in 2009, after all. But this message seems to have gotten lost in the chaos of health claims made by manufacturers in advertisements and on food labels.

You can do this right now by having a piece of fresh fruit, some nuts, or vegetables for a snack. Later, you can make most of your food purchases from the perimeter of the grocery store, and less from the aisles in the middle.

2. Move more. Most people spend too much time sitting and not enough time moving. In fact, the amount of time someone sits during the day has nearly as much impact on their health as their exercise habits. So, step one is to sit less.

Next, move more, which means just that—finding ways to be active during the day. This includes simple things like standing rather than sitting when you talk on the phone, taking the stairs instead of the elevator, and getting up off the couch during commercials. It also includes dedicating time every day for structured exercise or other activity like yard work, house work, or taking the dog for a walk. Every little bit helps, but aim for a minimum of 30 minutes per day.

Right now you are probably sitting, so stand up and stretch or move around a little. Later, go for a walk or do something active around your house.

3. Chill Out. With so much emphasis placed on diet and exercise, the health effects of stress are often overlooked. Chronic stress can have serious emotional, psychological, and physiological effects that lead to or exacerbate many health problems. While it is impossible to avoid all stress in life, minimizing stressors and managing the way you respond to stress can have important benefits.

Exercise is one good way to manage your feelings of stress as well as the effects it has on your body. Yoga has long been recommended to help reduce and control stress, but all types of exercise can help. Managing time better, including getting enough sleep, is helpful for many people.

Right now you can close your eyes and take a few deep breaths to relax. Later, spend some time doing something you enjoy.

So, if you are feeling overwhelmed by complicated and confusing health recommendations, keep it simple: eat smart, move more, and chill out!

Santa’s fitness report, just in time for Christmas.

Right now Santa is making the final preparations for his big night, from checking his list of good boys and girls to packing the toys in the sleigh and giving the reindeer a pep talk. As we can only imagine, a trip around the world in one night is quite a physical feat, so, like an athlete preparing for the Olympics, Santa has certainly been training all year for this  event.

Of course, Santa keeps his training regimen a secret. In my Health & Fitness column in the Aiken Standard this week I make an educated guess as what he does to prepare in the “offseason” and how this training helps him maintain good health despite his less-than-athletic physique. Santa’s training likely includes a combination of endurance, strength, and flexibility exercises.

Endurance training, probably a combination of both high-intensity interval training and long-duration, lower intensity training, leads to a high maximal aerobic capacity and fatigue resistanceProof for this is the fact that he flies away from each home with a hearty “ho, ho, ho.” If he were out of shape, he would be too short of breath to speak, much less give such a robust farewell!

Resistance training gives him the strength to repeatedly carry his heavy sack of gifts  up and down chimneys. In addition to traditional weight lifting, Santa probably also engages in plyometric training, which involves explosive movements that develop muscle power.

Stretching and exercises like yoga promote good flexibility so he can squeeze through narrow spaces and move quickly without pulling a muscle.

Santa certainly knows that proper training is only part of the answer, so he certainly focuses on sports nutrition, too. Many athletes use specialized sports drinks and foods that provide fluid, carbohydrates, and protein during long events. Santa relies on the cookies and milk you leave for him to provide the nutrients his muscles need to delay fatigue.

We can also learn an important health lesson from Santa. Even though he is overweight, through regular exercise, Santa has reduced his risk of health problems and maintained his fitness at a level that allows him to complete his necessary activities. Like Santa, all of us can benefit from being physically active, whether we are overweight or not.

Happy holidays!

Go Nuts (again)!

My Health & Fitness column in the Aiken Standard this week is about the health benefits of nuts. It is  a follow-up to a blog post I wrote a few weeks ago. This isn’t new, of course, since nut consumption has been recommended as a part of a healthy diet for years.

What is new is a recent study in the New England Journal of Medicine that shows that nut consumption was associated with a reduced risk of death from heart disease, stroke, and some cancers. The people who ate nuts every day got the biggest benefits.

That doesn’t mean that simply adding nuts to an unhealthy lifestyle will have some magical influence on health. In fact, the people in the study who ate the most nuts were also likely to do other healthy things like eat more fruits and vegetables, exercise, and not smoke.

The most practical advice is to eat nuts as a replacement for other snacks or to add nuts to salads and other dishes. While specific types of nuts have different health benefits, the recent study suggests that all nuts, including peanuts, are beneficial.

The mystery of how you can feel hungry shortly after eating breakfast explained.

Have you ever noticed that sometimes you can feel hungry—really hungry—midway through the morning, even after eating breakfast? Isn’t eating breakfast supposed to get you through the morning without feeling hungry?

The answer to these questions gets into why we eat and what regulates feelings of hunger. This is the topic of my Health & Fitness column in the Aiken Standard this week.

First of all, much of the time we want to eat we really aren’t hungry. Hunger is a physiological drive to seek food and is generally experienced as a negative sensation. It is a survival stimulus that got our caveman ancestors out of the cave to seek food, despite the threat of saber-tooth tigers. Hunger is a signal that energy and nutrients are needed and nearly any food will meet this need. In our world now, we rarely need such a powerful stimulus for us to seek food, and most people eat even though they aren’t truly hungry.

What we experience more often is appetite, a psychological sensation that motivates us to eat, usually in response to some sensory input. For example, the smell of fresh-baked cookies makes most people want to eat, even after a meal. In this case, it is the idea of food that triggers the sensation, not a physiological need for nutrients. Additionally, appetite is usually specific to a certain food we crave, like cookies.

One of the problems we face is that we often confuse appetite (wanting something to eat) with hunger (needing something to eat). This can lead to overeating.

It turns out that the foods we eat help determine how much we will eat in a meal and  contribute to our feelings of hunger later. A meal that contains a combination of foods providing carbohydrates, protein, fat, and fiber tend to make us feel full sooner, so we may eat less in that meal. By contrast, eating foods that contain primarily carbohydrates, especially refined grains and sugar, don’t have the same effect, and we can take in more calories before our brain gets the signal that we are full. This is called satiation.

That isn’t all. What you eat for one meal can influence how quickly you will feel ready to eat again later. This effect is called satiety. A meal that contains mostly refined carbohydrates can lead to feelings of hunger shortly after a meal. This why you can feel hungry midway through the morning after a breakfast consisting of a donut and juice.

One recommendation to help people eat less to lose weight is to eat foods that are high in fiber such as whole grains, fruits, and vegetables, since these foods tend to make us feel full sooner. Meals that contain a combination of nutrients, especially protein, can also help us go longer between meals.

So instead of a donut and juice for breakfast, try a piece of fruit (fiber!) and something containing protein, like an egg or yogurt.
