Book Review: Overcoming Binge-Eating by Christopher G. Fairburn

 Written by: Margaret Conte, Dietetic Intern

As a dietetic intern, we learn to calculate patient needs and how to present our findings to the patient. We receive training on counseling, but the focus is on nutrition. When it comes to treating eating disorder patients, in many ways the counseling is far more important than nutrition. “Overcoming Binge-Eating” gives an intimate look into the therapy and counseling side of treating binge eating disorders, and I believe it is a valuable read for all current and future dietitians.

            The book is divided into two parts, the first of which discusses the research and what is known about binge eating disorders. Part II is an evidence-based curriculum that can be followed by an individual alone or in conjunction with a therapist. One asset of the book is its readability. An individual need not be a medical professional to understand the information or follow the curriculum.


What is binge eating?

            Binge eating is more recently being recognized as an eating disorder with a psychological basis, rather than a merely lack of discipline when it comes to eating. Some people can binge, and it has no effect on their lives. This is called an indulgence and is a common phenomenon in men and women. When the repeated practice has a profound impact on a person’s quality of life and health, then it becomes an eating disorder, and we as dietitians can help with this. The two hallmarks of a binge are 1) the amount eaten is excessive in the eyes of the individual and 2) there is a sense of loss of control in the eyes of the individual.

            We are taught as nutrition students that binges are the result of restriction. According to Fairburn, the most common foods eaten in a binge are foods the person is trying to avoid. There is a myth that binges are characterized by high carbohydrate content, but in reality, the proportion of carbohydrates in a binge is no different than in ordinary meals. Binges are characterized by the amount of food rather than the macronutrient composition of the food.

            Binges can cause extreme distress in people. So why would someone subject themselves to feeling “gross” and “disgusted” over and over? This is important to understand in order to help someone overcome binge eating. One study interviewed women with bulimia nervosa who binge and revealed major precipitants of binges: tension, eating something (anything at all), being alone, craving specific foods, thinking of food, going home (after school or work), feeling bored and lonely. Other reasons for binges include undereating and the associated hunger (especially those who eat little outside of binges), breaking a dietary rule, and unpleasant emotions.

            Binge eating can be an eating disorder in itself, “binge eating disorder”, or it can be a component of anorexia nervosa, bulimia nervosa, or eating disorders not otherwise specified (do not meet the diagnostic criteria for anorexia nervosa, bulimia nervosa, or binge eating disorder). Many people who binge also diet. People who binge might think their dieting is in response to the binging, while in reality the binging may have initially resulted from the dieting, and the two cyclically encourage one another. The person may also engage in self-induced vomiting or laxative misuse, which encourages more binging. As we have learned in class, self-induced vomiting and laxative misuse can cause very serious health effects.

           

How can I use this book to help my patients?

Part II is a self-help program for people who binge. There are many concepts throughout Part II that hark back to the motivational interviewing and transtheoretical model of change we learned in counseling classes. It begins with the chapter, “Why Change?” and instructs the reader to “Start by drawing up a list of the potential advantages of change. To help you do so, ask yourself the following questions:

If I stop binge eating . . .

• Will I feel better about myself?

• Will it improve my quality of life?

• Will my physical health be enhanced?

• Will others benefit?”

            The rest of Part II outlines steps of the program. Step 1: Starting Well covers self-monitoring and weekly weighing. Step 2: Regular Eating establishes a pattern of regular eating and stopping vomiting and misuse of laxatives. Step 3: Alternatives to Binge Eating substitutes alternative activities and identifies changes in weight. Step 4: Problem Solving addresses problems that may be coming up. Step 5: Taking Stock reviews progress and decides what else needs to be tackled. Next there is a diet module which tackles strict dieting and a body image module that addresses shape concerns, shape checking, shape avoidance, and feeling fat. The program closes with the section Ending Well, which discusses maintaining progress and addressing setbacks.

 

Why is this important?

            Because eating disorders are so complex, it is especially important for the dietitian to collaborate with other professionals, and understand their own scope of practice and refer appropriately. I hope this blog post will encourage future dietitians to read “Overcoming Binge Eating”, because the information I have written here only scratches the surface of the links between dieting, binge eating, and eating disorders. We will be better dietitians for understanding where binging behavior comes from, and how to make recommendations appropriately for optimal health of body and mind.

Move with the BEET!


By Alyssa Bossle

What if there was such thing as a drink that could benefit your overall performance, increase blood flow, improve lung function and strengthen muscle contractions?  Well, you might be surprised to know, this drink already exists! Research has shown that beet juice has all these benefits and more for enhancing athletic performance. Diets rich in vegetables like beets are shown to have a significant impact on body functions during exercise as well as aid in recovery after a workout. In fact, beet juice is becoming one of the most popular ergogenic and natural supplements used by athletes.

So, what makes beets such an athletic nutritional superfood?

Beetroots contain high amounts of inorganic nitrates, and after they are consumed, beetroots increase levels of nitric oxide in the body.  This serves multiple functions related to increased blood flow, improved lung function and stronger muscle contractions, as mentioned earlier. Beets also provide a boost stamina, which helps the body last longer during exercise. It's been well researched that a diet rich in vegetables can improve cardiovascular health, due to this high nitrate content. While all vegetables contain some nitrates, they are more abundant in beetroots, leafy greens, spinach, celery, arugula, and parsley.

What does nitric oxide do for your body?
  • ·         Improves oxygen delivery to cells
  • ·         Expands blood vessels  
  • ·         Leads to lower blood pressure
  • ·        Improves overall circulation
  •         Boosts energy
  • ·         Aids in digestion
  • ·         Improves immunity
  • ·         Improves sleep quality

What does the research say on how much you need?

Every person is different, so it is difficult to state one specific number for the entire population. From what has been seen in studies, drinking as little as 4 oz, or half a cup, two to three hours before exercise is sufficient to receive the many benefits beet juice has to offer. In one study, a group of researchers wanted to find out if consuming more beet juice is better or if there is an upper level, so they put it to the test. They set up a group of men on an exercise bike and had them cycle until they exhausted all their energy and could no longer pedal. The subjects made it about eight minutes after drinking a placebo. After one ounce of beet juice, which is about a quarter of a cup, some participants gained a few seconds while others showed no change. However, drinking about 4 ounces, or half-cup, gave them a full extra minute without exhaustion. Drinking even more didn’t seem to offer any additional benefit. The 4 ounces of beet juice corresponds to 8 units of nitrate. So, 4 units didn’t significantly work, and 16 did no better than 8 units found in the 4 ounces. The 8 units, found in the 4 ounces of juice, appears to be the best amount for improving athletic performance (Wylie, L.J., 2013)

 *PL – Placebo
*BR – Beetroot Juice

What other benefits does beet juice provide?

Consumption of beet juice is known to have anti-inflammatory properties and antioxidant properties, which helps to reduce the oxidation of LDL, or the “bad” cholesterol, protect the artery walls and guard against heart disease and stroke, according to the American Journal of Clinical Nutrition. Beets are good sources of folate, potassium, vitamin C, and fiber. It also aids in the absorption of iron, which ensures that our muscles are working properly by delivering oxygen to our tissues.

Tips for beet juice consumption

·        * It is suggested to avoid drinking beet juice on an empty stomach. 
o   Beet juice is very acidic, and when taken on an empty stomach, it can make you feel more nauseated than energized.
·         *Try mixing with lemon juice and ginger to give it more flavor.
·        * If your drink is too thick you can add some water to balance the consistency.
·         *Mix in with other fruits or vegetables to make a smoothie. (See recipe below)
·         *Don’t remove the pulp! That’s where all the fiber is.

Try it out!

Although researchers have narrowed down a recommended amount of beet juice to be consumed in order to enhance performance and have significant benefits on health, further research is needed to determine long-term effects and outcomes on performance. 

If you are an athlete and are interested in consuming beet juice to enhance performance, it is important to check with your sports nutritionist, athletic trainer, or coach before consuming.
