For all my Canadian readers (and any international readers planning to attend), here just a quick reminder that the deadline for early bird discount registration for the upcoming 4th Canadian Obesity Summit in Toronto, April 28 – May 2, ends March 3rd.
To anyone who has been at a previous Canadian Summit, attending is certainly a “no-brainer” – for anyone, who hasn’t been, check out these workshops that are only part of the 5-day scientific program – there are also countless plenary sessions and poster presentations – check out the full program here.

Following the recent guest posts by Drs Vera Tarman and Pam Peeke on food addiction, many readers have left comments about how this notion rings true to them and how the ideas of treating their “eating disorder” as an addiction has helped them better control their diet and often lose substantial amount of weight.
Others have asked how to tell if they might be food addicts. For them, I am reproducing the following list of 20 questions taken from Food Addicts in Recovery Anonymous.
Although it is important to note that “food addiction” has yet to be officially recognized as a medical/psychiatric condition and the following questions are by no means “diagnostic”, I would still support the idea that the more of these questions you answer with yes, the more likely you may benefit from discussing this problem with someone who has expertise in addictions (rather than simply going of on another diet or exercise program).
1. Have you ever wanted to stop eating and found you just couldn’t?
2. Do you think about food or your weight constantly?
3. Do you find yourself attempting one diet or food plan after another, with no lasting success?
4. Do you binge and then “get rid of the binge” through vomiting, exercise, laxatives, or other forms of purging?
5. Do you eat differently in private than you do in front of other people?
6. Has a doctor or family member ever approached you with concern about your eating habits or weight?
7. Do you eat large quantities of food at one time (binge)?
8. Is your weight problem due to your “nibbling” all day long?
9. Do you eat to escape from your feelings?
10. Do you eat when you’re not hungry?
11. Have you ever discarded food, only to retrieve and eat it later?
12. Do you eat in secret?
13. Do you fast or severely restrict your food intake?
14. Have you ever stolen other people’s food?
15. Have you ever hidden food to make sure you have “enough?”
16. Do you feel driven to exercise excessively to control your weight?
17. Do you obsessively calculate the calories you’ve burned against the calories you’ve eaten?
18. Do you frequently feel guilty or ashamed about what you’ve eaten?
19. Are you waiting for your life to begin “when you lose the weight?”
20. Do you feel hopeless about your relationship with food?
Continuing with the theme of food addiction, here is another guest post – this one by Dr. Pam Peeke, a Pew Foundation Scholar in Nutrition, Assistant Clinical Professor of Medicine at the University of Maryland, and Senior Science Advisor to Elements Behavioral Health, the USA’s largest network of residential addiction treatment centers. She is author of the New York Times bestseller The Hunger Fix: The Three Stage Detox and Recovery Plan for Overeating and Food Addiction. Her website is http://www.drpeeke.com/
For years, the popular culture has embraced the relationship between food and addiction. It permeates our daily vernacular— “I’m hooked on bread”, “I need a candy fix”, “I can’t get off the stuff”, “I’m a carb addict”. Grocery store shelves are filled with colorful cereal boxes labeled “Krave”, as the food industry capitalizes on the consumers’ never ending hunger for another fix. History was made when a major weight management company aired its first Super Bowl commercial, choosing a “food as drug” theme, narrated by Breaking Bad actor Aaron Paul. Close your eyes, listen to the words, and you’d never guess that food, not drugs, was the focus. Companies and communities, however, cannot validate the phenomenon of addictive eating behavior—only science can do that.
Heeding the call to arms, nutrition and addiction researchers, led by Dr. Nora Volkow, Director of the National Institute of Drug Abuse, have spent the past ten years generating a critical mass of valid and credible science associating specific food products and addictive eating behavior. A tipping point was reached in 2012, when the peer reviewed and edited professional textbook Food and Addiction was published. A month later my consumer book, The Hunger Fix: The Three Stage Detox and Recovery Plan for Overeating and Food Addiction, was released and the single most common response from my readers was “What took you so long?” We needed, and finally benefited from, new groundbreaking research.
We now know that certain foods, namely the “hyperpalatables”–sugary, fatty, salty food combinations— affect the brain’s reward center in a way identical to drugs and alcohol, triggering an abnormally high level of release of the pleasure chemical dopamine. Repeated hyper-stimulation of these reward pathways can trigger neurobiological adaptations that can lead to compulsive consumption despite negative consequences.
In 2009, Yale researchers developed the first assessment tool, the Yale University Food Addiction Scale, or YFAS, to identify individuals who demonstrated an addictive response to specific foods. Subsequent studies using the scale have shown that there is a wide spectrum of people who present with addictive eating behavior, especially in those who are overweight/obese, female, over 35, or who have existing disordered eating patterns such as binge eating disorder or bulimia. Ongoing investigations have noted that among women, there is a 90 percent association between food addiction and prior history of abuse, especially in childhood and adolescence. As well, the incidence of addictive eating in women increases with post-traumatic stress syndrome.
As scientific evidence continues to mount clarifying the connection between food and addiction, attention is now beginning to focus on treatment options. Treatment for addictive eating behavior is of particular interest to me as a scientist and a clinician. I recall one of my patients, a former alcoholic with a disabling sugar addiction, declaring, “If drinking is black and white – I drink or I don’t– sugar is more shades of grey than there are books.” Indeed, in contrast to drugs and alcohol, treatment for the psychobiological challenges of addictive eating is far more complex. In a prior blog, Dr. Vera Tarman addressed abstinence as one treatment option.
Who is the target treatment population? It’s not just obese, compulsive overeaters. It also includes thin, average and mildly overweight men and women experiencing a full range of eating disorders (ED), mood syndromes and substance abuse. Within these groups there are numerous intricate interconnections, interrelationships and co-occurrences. For instance, current research suggests that approximately 50% of those with an ED are also substance abusers, including 57% of men with binge eating disorder experiencing long-term drug and alcohol abuse. Cross addictions abound as people transition from drugs to cupcakes, from alcohol to sugar, and from bariatric surgery to alcohol. This complicated web of interrelationships is one reason that determining the precise prevalence of food addiction is such a challenge.
In essence, the larger the treatment population, the wider the spectrum of therapeutic modalities required, and thus, the greater the need to individualize and customize treatment for addictive eating behaviors. To address this challenge, I have created the Integrative Nutrition and Holistic Lifestyle Program at Malibu Vista in California. This women’s residential treatment program treats women, many of whom have co-occurring mood and food conditions, specifically addictive eating. This pilot program has garnered national attention including a recent NBC Today Show segment.
The program’s blueprint is based upon my three pronged, customized approach to: 1. mental/spiritual wellness (MIND); 2. whole food nutrition (MOUTH); and, 3. physical activity (MUSCLE). Therapists use a wide range of cognitive psychotherapeutic methods to treat mental health conditions including trauma. Body movement modalities include yoga, tai chi, and meditative walks to foster an improved mind-body association. Nutritionally, the chefs have eliminated any refined or processed foods, including table sugar and artificial sweeteners. Our culinary nutritionist, who is both a certified chef and registered dietitian, assesses each woman. This includes completion of the Yale Food Addiction Scale, a metabolic evaluation, and documentation of any history of substance abuse and disordered eating. An individualized plan is created and refined during the typical 4-5 weeks in-residence. Through hands-on cooking lessons and nutrition education sessions, individuals can reframe and redefine their relationship with food. Group fellowship is critical to ongoing support and success. Continued coaching continues upon discharge. For example, Sandie, featured in the Today Show segment, is now off her anti-anxiety medications, no longer binges, has halved her diabetes medication, and has thus far removed over 50 pounds of excess weight.
In honoring each woman’s unique story and the complexities of treating addictive eating behavior, the Malibu Vista team draws upon elements found from a multitude of resources, including but not limited to 12-step programs. Individualized strategies are designed to use a wide range of interventions to optimize body-brain-mind healing. The end goal is to help each person manage the triple challenge posed by the food-mood-addiction triad, and in doing so, create a blueprint for long term recovery, and success in navigating addictive eating’s many shades of grey.
Recently, I had the opportunity of meeting Vera Tarman, a Toronto addiction physician, who is also a self-proclaimed “food addict” and author of the book, “Food Junkies: The Truth About Food Addiction“.
It is fair to say that talking to Tarman and reading her book (of which she happily gave me a copy) has definitely given me food for thought.
To start with, her book “Food Junkies” is not a typical diet book or even a treatment guide to food addiction.
Rather, it is a rather compelling treatise in support of the existence of a discrete and definable subset of obese (and non-obese) individuals who may well be considered “food addicts” and for whom the only viable treatment is complete abstinence from their respective trigger foods.
To put things simply, Tarman (and her co-author Philip Werdell) describes three categories of “eaters” (the following words my attempt at paraphrasing the central ideas as I understand them):
Normal Eaters: this is by far the largest group of individuals with obesity, who may overeat for no other reason than that they like food, are surrounded by food, pay little attention to food, let themselves go hungry, have food pushed on them, and/or really don’t obsess or worry about food at all. Normal eaters can learn to control their eating through education and coaching and by changing the circumstances that foster poor willpower: better sleep, stress management, improving social skills, changing their personal food environment, etc.
People with Eating Disorders: for this group of individuals, obesity is not the primary problem, rather it is just another symptom of the underlying emotional disturbances that drives their “pathological” eating behaviour. The “spectrum” of these disorders ranges from rather mild “emotional eating” to full blown “binge eating syndrome”. The primary driver of their overeating is psychological (e.g. trauma, grief, abuse, etc.). Once the psychological problem is identified and resolved (or managed, e.g. though cognitive behavioural therapy), they can gain control over their eating behaviour, which in turn can help them control their weight problem.
Food Addicts: this group of individuals is literally “addicted” to certain foods (usually foods high in sugar, flour, fat and/or salt) in the same manner that a drug addict would be considered addicted to their drug, with the same clinical signs that range from denial and loss of control, to physical symptoms on “withdrawal” and relapse that can be prompted by minimal exposure, even years after being “clean” or “sober”.
According to Tarnan and Werdel, this grouping has important implications for clinical management.
While a “normal eater” and someone with an “eating disorder” can eventually learn to practice “moderation”, this is virtually impossible for the true addict – the only viable strategy for them is complete and lifelong abstinence (best coupled with a 12 steps program or something similar).
For the true “food addict”, no amount of education, psychological counselling or attempt at “moderation” will ever lead to success. Any attempt to get the “food addict” to learn how to “use” their “drug” in moderation will be as futile as trying to get a drug addict to learn how to use alcohol or heroin (or any other drug) in moderation (the vast majority will fail).
As to how the “food addict” can practice abstinence, the Food Junkie acknowledges that this is difficult but achievable. Obviously, the goal will be to completely eliminate and abstain from the “trigger foods”, which will vary from individual to individual (and people may well bounce around from one food to the next). Nevertheless, a good place to start is probably with foods that contain sugar, flour, are highly processed, high in fat or otherwise “addictive”.
For some it may mean a low-carb, for others a paleolithic diet, or simply a fruit and vegetable-based high protein diet with some fat thrown in for satiety – here Food Junkies discusses the various options, while acknowledging that there is no hard and fast rule – only, that it can be achieved (a point that the authors illustrate using their own stories and those of their patients).
All of this said, the authors are the first to acknowledge that there is much about food addiction that we don not yet know or fully understand.
For one, making the diagnosis is anything but easy – often, this “diagnosis” can only be made when all attempts at “moderation”, despite best efforts, fail.
The authors also accept that we do not know the prevalence of true food addiction – only, that it may be higher than we think.
If nothing else, the book is a quick and fascinating read for anyone interested in the issue – patient or professional.
It certainly has got me thinking about whether or not “abstinence” may indeed be a viable approach for some of my patients.
For anyone, who has questions regarding this concept, Dr. Tarman has kindly agreed to address these in a subsequent guest post on these pages – so please send me your comments/questions.
Last week, the US Endocrine Society released a rather comprehensive set of evidence-based clinical practice guidelines for the pharmacological management of obesity, published in the Journal of Clinical Endocrinology and Metabolism.
The recommendations in the 21-page document follow the rather rigorous Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) group (from 0 to 4 stars) and goes beyond just evaluating the evidence in favour of pharmacological treatment of obesity itself but also for the pharmacological treatment of overweight and obese individuals presenting other medical conditions.
Here are the (in my opinion) most important recommendations from this document:
1) While diet, exercise and behavioural interventions are recommended in all patients with obesity,
“Drugs may amplify adherence to behavior change and may improve physical functioning such that increased physical activity is easier in those who cannot exercise initially. Patients who have a history of being unable to successfully lose and maintain weight and who meet label indications are candidates for weight loss medications.(****)”
2) “If a patient’s response to a weight loss medication is deemed effective (weight loss > 5% of body weight at 3 mo) and safe, we recommend that the medication be continued. If deemed ineffective (weight loss < 5% at 3 mo) or if there are safety or tolerability issues at any time, we recommend that the medication be discontinued and alternative medications or referral for alternative treatment approaches be considered. (****)”
3) “If medication for chronic obesity management is prescribed as adjunctive therapy to comprehensive life- style intervention, we suggest initiating therapy with dose escalation based on efficacy and tolerability to the recommended dose and not exceeding the upper approved dose boundaries. (**)”
The guidelines also make specific recommendations for the pharmacological treatment of overweight and obese individuals presenting with a wide range of other medical issues, including 2 diabetes mellitus (T2DM), cardiovascular disease, psychiatric illness, epilepsy, rheumatoid arthritis, COPD, HIV/AIDS and allergies.
“In patients with T2DM who are overweight or obese, we suggest the use of antidiabetic medications that have additional actions to promote weight loss (such as glucagon-like peptide-1 [GLP-1] analogs or sodium-glu- cose-linked transporter-2 [SGLT-2] inhibitors), in addi- tion to the first-line agent for T2DM and obesity, metformin. (***)”
The guidelines also discuss the pros and cons of the anti-obesity medications currently available in the US (phentermine, orlistat, phentermine/topiramate, lorcaserin, buproprion/naltrexone, and liraglutide), which we can only hope will soon also become available to patients outside the US.
