Social Stigmatization
In American and other Westernized societies there are powerful messages that people, especially women, should be thin, and that to be fat is a sign of poor self-control. Negative attitudes about the obese have been reported in children and adults, in health care professionals, and in the overweight themselves.
People's negative attitudes toward the obese often translate into discrimination in employment opportunities, college acceptance, less financial aid from their parents in paying for college, job earnings, rental availabilities, and opportunities for marriage.
Much of the research on the social stigma of obesity has suffered from methodological limitations. There has been a lack of research that has looked at the impact of obesity in the context of other variables, such as physical attractiveness, the situational context, and the degree of obesity. In addition, social stigma toward the obese has primarily been assessed among white individuals.
In addition, the degree of acceptance of obesity among people of lower education and income has not been well studied. Thus, these data are very incomplete with respect to racial and ethnic groups other than whites.
Psychopathology and Obesity
Research relating obesity to psychological disorders and emotional distress is based on community studies and clinical studies of patients seeking treatment. In general, community-based studies in the United States have not found significant differences in psychological status between the obese and non-obese. However, several recent European studies in general populations do suggest a relationship between obesity and emotional problems. Thus, it may be premature to state that there is no association between obesity and psychopathology or emotional distress in the general population. More focused, hypothesis-driven, and long-term studies are needed.
Overweight people seeking weight loss treatment may, in clinic settings, show emotional disturbances. In a review of dieting and depression, there was a high incidence of emotional illness symptoms in outpatients treated for obesity. However, several factors influenced these emotional responses; including childhood onset versus adult onset of obesity (those with childhood onset obesity appear more vulnerable). Another study that compared different eating disorder groups found that obese patients seeking treatment showed considerable psychopathology, most prominently mild to severe depression.
Body Image
Body image is defined as the perception of one's own body size and appearance and the emotional response to this perception. Inaccurate perception of body size or proportion and negative emotional reactions to size perceptions contribute to poor body image. Obese individuals, especially women, tend to overestimate their body size.
People at greater risk for a poor body image are binge eaters, women, those who were obese during adolescence or with early onset of obesity, and those with emotional disturbances. It is no surprise, then, that in some groups of obese persons, these individuals are more dissatisfied and preoccupied with their physical appearance, and avoid more social situations due to their appearance.
Body image dissatisfaction and the desire to improve physical appearance often drive individuals to seek weight loss. However, obese persons seeking weight reduction must come to terms with real limits in their biological and behavioral capacities to lose weight. Otherwise, weight loss attempts may only intensify the sense of failure and struggle that is already present among many obese individuals. For this reason, psychosocial interventions which incorporate strategies to improve body image may be helpful for those who want to lose weight and are very concerned about their physical appearance.
Side effects of slimming pills
Many slimming pills have now been taken off the market because of potential side effects and complications.
Amphetamine-type slimming pills were popular 30 to 40 years ago, but it took some time for doctors to realise they can be addictive and harmful. Few people managed to diet successfully with them and keep weight off, and many became physically hooked.
Even the more recent appetite-suppressant drugs, such as dexfenfluramine, have now been taken off the market in most countries, as research has linked their use to long-term problems such as heart disease.
New slimming drugs
Some new medicines to help people lose weight have been licensed in recent years. One, called sibutramine, alters the chemical messages in the brain that control how the person feels about food. By influencing brain chemicals called noradrenaline and serotonin, sibutramine helps to make a person feel full. Another, called orlistat, changes the way the stomach or intestines function, so that less fat enters the bloodstream. Several other drugs are in the development stage.
But, like any treatment, they have side effects. Sibutramine sometimes increases blood pressure, for example, while orlistat can cause diarrhoea and flatulence.
Anti-obesity drugs are only really suitable for very overweight people. Doctors are advised to only prescribe them in special circumstances. For example, as part of an overall treatment plan for the management of obesity for people aged 18 to 65 years with a body mass index (BMI) of 30 or more. Or where someone has a BMI of 27 or more and has another significant disease, such as type 2 diabetes or high cholesterol. The person must have already made serious attempts to lose weight by dieting, exercise and/or other changes in their behaviour.

South Beach Diet
This diet teaches participants to rely on the right carbohydrates and the right fats - the good ones. As a result, participants lose weight, lower their cholesterol, reduce their risk of heart disease and diabetes, and eliminate cravings without feeling hungry. Some call it the “updated version of the Atkins diet”
The origins of the South Beach Diet lay with Arthur Agatston, MD, a cardiologist whose motivation was to improve the cholesterol and insulin levels of his patients, who had heart disease, by developing a healthy eating plan. Agatston has also published a book about his plan, The South Beach Diet: The Delicious, Doctor-Designed, Foolproof Plan for Fast and Healthy Weight Loss which is growing in popularity by the day.
Although a glamorous name the South Beach Diet involves a high degree of determination and self motivation. It appears to be scientifically based and is rich in vegetables, fruits, whole grains, and lean protein, and it doesn't omit any major food groups.
According to Agatston, at the end of two weeks, most participants on the South Beach Diet are 8 to 14 pounds lighter. He notes the weight loss does not happen because participants eat less, but rather because eliminating simple carbohydrates has broken a bad eating cycle. As a result, participants continue to lose weight after the initial two-week period.
South Beach Diet Phases
Phase 1, The Strictest Phase of the Diet - Lasts 14 days
In the first phase, you eat normal-sized helpings of lean meats, such as chicken, turkey, fish, and shellfish. Vegetables are also allowed, so are nuts, cheese, and eggs. The goal is to eat three balanced meals a day, and to eat enough so that you don’t feel hungry all the time.
Diet Foods to enjoy includes tenderloin, sirloin, skinless chicken or turkey breasts, all types of fish, boiled ham, turkey bacon, whole eggs, fat-free cheeses, peanuts and pistachios, green vegetables, legumes, canola and olive oils.
Diet Foods to avoid include, beef rib steaks, honey-baked ham, breast of veal, all yoghurt, ice cream, milk including whole, low-fat, soy, and full fat cheeses, beets, carrots, corn, yams, fruits and fruit juices, all alcohol, all starchy foods such as bread, cereal, oatmeal, matzo, rice, pasta, pastries, baked goods, crackers, etc.
Expected Weight Loss: 8-13 pounds.
________________________________________
Phase 2, More Liberal Phase Lasts Until You Reach Your Weight Loss Goal
The second phase is similar to the first phase, but you reintroduce some of the banned foods and eat from all the dietary food groups. You can start eating high-fibre carbohydrates, such as whole-grain breads, which raise your insulin levels in a much milder way that do simple, starchy carbohydrates.
Additional Diet Foods to enjoy include most fruits, fat-free or 1 percent milk, other low-fat dairy foods, whole grain starches, barley and pinto beans and red wine.
Diet foods to eat sparingly, include: refined wheat baked goods, potatoes, beets, carrots, bananas, pineapple, watermelon and honey.
Expected Weight Loss: 1-2 pounds per week.
________________________________________
Phase 3 - Weight Maintenance
This diet phase, which is an even more liberal version of the initial diet plan, lasts the rest of your life. It should be used to maintain your healthy weight. Agatston describes this phase as a “way of life.” Should your weight begin to climb, you repeat the diet plan.
Drawbacks of the South Beach
Although weight loss is achieved on the South Beach Diet some questions have been raised about the ability of the South Beach Diet to induce ketosis. This is a state when your body does not have carbohydrates to digest and results in rapid weight loss being achieved. Some health professionals are not convinced that by dropping carbohydrates and placing a greater emphasis on protein this is enough to induce ketosis.
Much of the initial 8-13 pounds weight-loss is likely to be water-weight-loss caused by carbohydrate restriction. This weight loss is usually regained, as soon as carbohydrate intake resumes. A further drawback of the South Beach Diet is that it doesn’t fully cater for people who don't or can't eat dairy. Many snacks are dairy-based, yet the diet bans soy in the first two weeks.
Although Dr. Agatston has concerns regarding the liberal intake of saturated fats permitted on the Atkins diet plan, and offers sound advice on the subject, the issue on complex carbohydrates remains unaddressed. Most of the world outside America thrives on complex carbohydrates and these foods do not keep us overweight, nor do they warrant a 14-day ban.
As with any diet, despite the many positive aspects of Agatston's South Beach Diet, participants should consult a doctor before commencing. A balance diet and healthy lifestyle combining exercise is vital to maintaining weight loss.
The South Beach and Jenny Craig diet plans are lacking in any sort of clinical evidence. As mentioned earlier, the biggest problem with all of these diets is simply the adherence. In many of the randomized studies, drop-out rates were as high as 45%. And those that did manage to stay with the diet were not very strict in following the diet exactly as it requests.

Sear's Diet
Sear’s Diet aka Zone Diet
Celebrities like Madonna, Demi Moore and Jennifer Aniston swear by the results of the Zone Diet created by Barry Sears, PhD. The Zone Diet contains 40% carbohydrate, 30% protein and 30% fat and is also known as the 40-30-30 plan. The Zone Diet works on the premise that 100,000 years ago, we were meat eaters and our bodies was designed to handle the demands of a meat-based diet.
As we have evolved, more carbohydrates have been introduced into our daily diet, causing an imbalance. The reason for our extra weight could be attributed to the many grains and starches in our diet (pasta, rice, breads, and potatoes). The Zone Diet’s strategy calls for a return to the diets of our ancestors where meat, fruits and vegetables are the main dietary items.
How Does The Zone Diet Work?
The Zone Diet works by working the right ratio of carbohydrates to proteins and fats in order to control the insulin in the bloodstream. Too much of the hormone (insulin) can increase fat storage and inflammation in the body (conditions that are associated with obesity, type 2 diabetes and heart disease). Sears asserts that by using the Zone Diet, you are actually optimizing the body’s metabolic function. Through the regulation of blood sugar, you allow your body to burn excess body fat.
The Zone Diet does not actually prohibit you from any particular food group; however food with high fat and carbohydrates such as grains, starches, and pastas should be avoided. Fruits and vegetables are the preferred source of carbs and monounsaturated fats (such as olive oil, almonds, avocados) are the ideal choice of fats. The Zone Diet claims to use food as a drug for overall good health, weight loss and prevention or management of heart disease and diabetes.
Risks/ Disadvantages
The AHA (American Heart Association) classifies the Zone Diet as high protein and does not recommend the Zone Diet for weight loss. They assert that the Zone Diet has not been proven effective in the long term for weight loss. They issued an official recommendation warning against diets like the Zone Diet.
They believe that the Zone Diet is hazardous as it restricts the intake of essential vitamins and minerals present in certain foods.
They are concerned that the protein ratio in the Zone diet is too high even if the minimal fat ratio is good. Robert H. Ecker M.D of the A.H.A., finds the Zone Diet’s theory on insulin flawed and argues that there is no scientific proof that the hormone insulin plays a big role in weight regulation.
According to Bonnie Liebman, at the Center For Science in the Public Interest, it's nothing new. "Miracle diets come and go like hemlines, hair-dos, and celebrity romances." Furthermore, they don't work; and all of them have the potential of raising low density lipoprotein (LDL) levels. And finally, what do these diets do for the authors themselves? Both Dr. Atkins and Barry Sears have exceeded the upper limits of weight recommended by federal guidelines.
Clinical studies conducted during the last half century, clearly show that a high-protein, high-fat, low-carbohydrate diet leads to higher rates of heart disease, stroke, hypertension, adult onset diabetes, and many types of cancer.
The relationship of animal fat to cancer is stronger than ever before. According to new studies released by the Environmental Protection Agency, potent carcinogens from industrial wastes, such as dioxin and other chlorinated compounds, are known to be concentrated in the animal fat of meat, fish, and dairy products. On the other hand, vegetables, fruits, and grains contain only small amounts of these compounds.
Its followers defend it vehemently, largely because they find the rapid weight loss irresistible. Like most low carbohydrate diets, however, a great deal of the weight loss is dehydration. Ordinarily, three grams of water are stored with every gram of carbohydrates in the form of glycogen in the liver and skeletal muscles. When this is sharply limited, the desperate "zonies" think they are losing up to a pound of fat a day. It's also low in calories (about 1,700), causing the unhealthy depletion of lean body mass along with the minimal fat loss.
Also, without careful monitoring, this type of diet may lead to "ketosis" (an unnatural form of acidosis), which often causes some degree of anorexia and even euphoria. Sears denies that this happens with the amount of carbohydrates he allows.

Complications of Overweight/Obesity
Hypertension
- related to substances produced by adipose tissue and the increase in the hormone insulin
Diabetes
- obesity is the leading cause of diabetes; risk of diabetes increased over 53 fold with severe obesity
- Type II Diabetes not Type I
Hyperinsulinemia, insulin resistance, glucose intolerance
Elevated cholesterol
- every 10 lbs of excess fat produces 10mg of cholesterol per day
Fatty liver
- Non-Alcoholic Steato-Hepatitis caused by excessive fat deposition in the liver
- Due to excess fat intake
- Results in silent inflammation, usually detected by liver function tests
- If untreated, can develop cirrhosis or liver failure
Cancer
- in females, 3 fold increase in the incidence of breast, uterine, cervical and ovarian cancer
- in men, there is an increased incidence of colon and prostate cancer
Degenerative arthritis (osteoarthritis)
- increased weight causes more wear and tear of the joints
- adipose tissue produces cytokines that “destroy” the normal cartilage in joints
Gallstones
- due to increase in cholesterol
- cholecystitis
CVD (Heart attacks, angina pectoris, CHF) and strokes
- increased incidence of strokes and heart attacks
- due to elevated blood pressure, diabetes, and elevated cholesterol
Sleep disorders
- feel tired all the time and have problems obtaining a restful sleep
- could be sleep apnea: becomes more difficult to breathe as their weight increases
- heart rhythms can become irregular leading to heart attack
- could lead to depression and anxiety due to lack of sleep
Polycystic ovarian syndrome

•gene mutations in the mitochondria
•Shared familial characteristics in the environment
–Food preferences
–Lifestyle factors
It’s everywhere!!!
•Fast food / junk food
•Busy work
•Sedentary lifestyle – couch potatoes!
•Inadequate physical exertion
Psychological factors
•Food <-------> emotion
•Depression and stress lead to eating disorder, hence obesity.
Endocrine
•Cushing’s Syndrome – excess cortisol stimlating appetite

•Impeded leptin production – inability cells to signal satiety
•Insulinoma
•Polycystic Ovarian Syndrome
“Fattening” Medications
•Note: May have different properties in different individuals.
•Lithium for manic bipolar disorders
•Cortisone for rheumatism and allergies
•Anti-seizure medicines (Valproate)
•Antidepressants
•Migraine medicines (Sandomigrin, Ergenyl, Trypizol)
•Oestrogen (Follimin, Follinett, Neovletta)
•Insulin for type 2 diabetes (Insulatard, Humulin, Actrapid)
•Breast cancer medicines (Nolvadex, Tamoxifen)
•Beta blockers (Inderal, Cardura)
