I've been meaning to blog about 'critical obesity' forever- but just haven't been able to find time. However, a classmate of mine, Nicole Bergen, wrote a great article on the topic, for her journalism class. It's such a well-written piece that offers a great overview of the subject, and I'm so happy she gave me permission to post part of it for you to read.
Great job, Nicki!
Sara can hardly remember a time when she wasn’t concerned about her weight. Since the age of 16, she has experimented with Weight Watchers, appetite-suppressant pills, restrictive diets and arduous exercise routines. The now-24-year-old teacher consulted a number of medical doctors for weight advice, but grew increasingly disheartened with their approach. “They were putting it on me that I was lazy or that I got this way because I never exercise or have unhealthy habits, “ Sara said. “They told me what an optimal [weight] goal would be, but didn’t offer any new insight on how to get there.”
Dr. Arya Sharma, a Professor of Medicine and obesity researcher at the University of Alberta agrees that the medical profession may not be adequately prepared to offer constructive weight-loss advice. “Not all health care providers are trained to assess and treat obesity,” he said.
The current Canadian Clinical Practice Guidelines for Obesity define overweight and obese according to a patient’s height and weight, using a measurement known as BMI (body mass index). For most overweight patients, the guidelines emphasize weight loss through diet and exercise therapy. Sara said that she spent only about 10 minutes discussing healthy lifestyle choices with her doctor.
This type of approach is almost certain to fail as a weight-loss treatment. Studies from a variety of regions and populations repeatedly log success rates of less than five per cent. In a 2007 edition of the
Journal of the American Dietetic Association, the combined results from 80 scientific reports concluded that advice-based weight-loss attempts produced minimal results, both initially and in the long-term.
A little unsettling for a nation with no shortage of overweight and obese people trying to lose weight.
Lucy Aphramor, a dietitian and obesity researcher in the UK, questioned the ethics of recommending weight-loss treatments that have such resounding failure rates. In 2005 she wrote “The reality is that we do not have an effective weight-loss treatment to recommend.”
Societal demonization of fatness may be fuelling an obsession with thinness. Motivation to lose weight has extended beyond health concerns, to a pursuit for social acceptance. And, according to Sharma, this is an important distinction. It usually takes only a small amount of weight loss to see significant health benefits; the process of achieving a desired body type, however, requires more effort.
“Managing expectations is a big part of making weight goals,” Sharma said. “It is never a good idea to use optimism as motivation or set someone up for failure.”
When Sara’s doctor provided unhelpful advice, she joined a gym and began weekly sessions with a nutritionist and personal trainer. “They probably spent about three hours catering a diet to my specific needs,” she said. “I have polycystic ovarian syndrome, and when I first approached them they didn’t know a lot about it. They did some research and developed a good understanding.” Sara is confident in the advice that she receives at the gym, and has met some of her goals.
After working in the weight-loss industry, Mabel Pang-Bishop has changed her views about weight-loss treatment. Pang-Bishop sold meal supplements for a commercial weight-loss program for two years, and then realized that she had become part of the problem. “We marketed a program that was very restrictive and claimed to be a safer alternative,” she said. “But the program is structured for people to fail. There were some successes, but mostly yo-yoing. Our customers saw themselves as failures in their weight-loss goals and therefore failures in life.”
Now, Pang-Bishop is a graduate student at the Ryerson School of Nutrition, studying an emerging field she calls ‘critical obesity studies.’ A critical perspective on obesity promotes health at every size, and looks beyond diet and exercise to broader, social determinants of health and social justice. “I knew there was something more to weight loss than energy in and energy out,” she said. “Why do we accept ideas without questioning them? It is important to be aware that there’s more out there.”
Gwyneth Paltrow does it. So does Angelina Jolie, Oprah, Liv Tyler, Ben Affleck and Christy Turlington (to name a few). Beyonce did it to lose 20lbs quickly for DreamGirls. I’m talking about “detox” or “cleansing” diets.
What are detox/cleansing diets?
There are different variations of detox diets but all claim to clean out our bodies of chemicals and dietary toxins. The supposed result: weight loss, increased energy, better digestion. Another claim is that by allowing the cells in the gut to rest, they are able to grow stronger, resulting in a healthier gut.
You can ‘detox’ by eliminating certain foods from your diet- Oprah recently followed a 21-d detox diet in which she eliminated animal products, sugar, alcohol, caffeine and gluten. The stricter versions are liquid diets- lemonade (followed by Beyonce and others) or juice fasts where followers will drink anywhere from 32 to 90 oz juice/24 hours, and even water fasts. Many of these diets also suggest enemas. These diets vary in time- from 1 day to a few weeks.
Do they work?
There is no scientific evidence available to support any of the claims these diets make- only people’s testimonials. Most health professionals, myself included, will tell you that our body is able to “detoxify” itself naturally. Abstaining from food will not help you be healthier. In fact, fibre’s role is to help clean out the gut- so a diet that’s rich in vegetables, fruits, whole grains, beans and lentils and other lean proteins and water would be the perfect detox diet!
With summer coming up, you may be tempted by this supposed “quick fix” to weight loss. However, for the most part, these diets and fasts are an ineffective weight loss solution. If you do lose weight, it’ll mostly be water weight and you’ll most likely regain it... quickly. Any diet that eliminates major food groups (or food, for that matter!) is not sustainable- definitely not a long-term solution. Moreover, many of these diets are extremely low in calories. As a result, your body goes into ‘starvation mode’- your metabolic rate will decrease so you’re burning less calories at rest. Moreover, your body will hold on to its fat stores (because it’s more energy-efficient) and burn lean muscle... something you obviously want to avoid. When you start eating again, your body will more easily store those calories as fat and, as a result, you’ll regain the weight faster.
You need to eat to lose weight!
These diets also lack major nutrients: protein, an essential nutrient in helping you maintain lean muscle mass during weight loss, as well as fat, an essential nutrient that, among other things, is essential in helping you feel full after a meal. As a result, people claim to always feel hungry on these diets... something that is not only uncomfortable but can cause irritability and lead you to eat irrationally afterwards. Beyonce was quoted as saying: “I was hungry, therefore I was evil. When we wrapped the movies, I was so excited... I ate a whole dozen Krispy Kreme doughnuts”. It was also reported that she quickly regained the weight she had lost on the diet... a fact that’s ignored by followers of the same diets!
A dietitian calculated that the Master Cleanse diet (a well-known detox diet that consists of drinking 96 oz of lemonade with maple syrup and cayenne pepper a day) is 1300 calories. A woman should never eat less than 1200 calories and a man, never less than 1500 calories. So, for a woman, 1300 calories isn’t drastically restrictive. However, it lacks major nutrients. Why not eat 1300 calories of fibre-rich vegetables, fruits, whole grains, lean proteins and drink water?! You’re more likely to stick to a meal plan that includes real healthy foods, you’ll lose weight, and you’ll also have more energy to exercise- an important key to long-term weight loss!
Oftentimes, these diets are used to “jump start” weight loss, ie. They start with a strict “detox” diet for a few days and follow it with a weight loss program. Maybe. A diet (under the supervision or guidance of a Registered Dietitian or doctor) that restricts certain foods, ie. alcohol, sugar, animal products (if replaced by vegetable protein), can be useful in motivating someone to kick-start a weight loss program and perhaps feel ‘cleansed’. As long as the diet is not overly calorically-restrictive and includes all the major nutrients, it can be an effective motivational tool to start a healthy weight loss program... although, not necessary.
What are the risks?
Evidently, the extreme diets, (fasting- no food) are extremely dangerous. However, even restrictive diets can be dangerous if you’re not replacing the nutrients you’re eliminating. As a result, speak to your doctor and/or a Registered Dietitian before embarking on any diet.
Many of these detox diets will rightfully warn pregnant and breastfeeding women and women trying to become pregnant against trying them. Children should not be put on these diets. These diets can widely affect blood sugar levels so people with diabetes and low blood sugar (hypoglycaemia) should avoid them as well.
If you’re recovering from an illness or injury, suffer from anemia, have weakened immunity (ie. elderly), have heart problems, psychological problems (depression, bipolar disorder, prone to eating disorders), are underweight and/or suffer from migraines, you should not embark on these diets- they can exacerbate existing illnesses or delay healing/recovery.
Apart from irritability, side effects of liquid diets and fasts can include GI problems, ie. diarrhea and/or constipation, dizziness, difficulty concentrating, fatigue, depression, headaches, fainting, irregular heart beats, dehydration and even death.
