5. If so many want to lose weight and need to… Why are we failing to do so?

6. Set Point Theory • Set Point is a particular weight range your body fights to maintain • Contributing Factors: • Heredity, Age, Health, and Activity Level • Your body defends this set point by altering: • Metabolism, Efficiency in burning calories, and Intensity of hunger

7. Set Point • Increases with: • Age • Chronic Dieting • Chronic Overeating • Long-term Depression • Maintaining a weight above set-point • Decreases with: • Exercise • Nicotine • Some drugs

8. The Weight Cycling Effect of Repeated Dieting “Each round of dieting is followed by a rebound of weight to a higher level than before.” Understanding Nutrition, 8th ed. Pg 262

9. Recommendations for Healthy Weight Loss • No more than1 to 2 pounds a week • “Rapid weight loss may cause serious health problems.” • Nausea, headaches, and dizziness • Death • “Rapid weight loss is a loss of more than 1 ½ to 2 pounds per week or weight loss of more than 1 percent of body weight per week after the second week of participation in a weight-loss program” • It is important to consult a physician prior to beginning any weight-loss program. Understanding Nutrition, 8th ed. Pg 261

11. FAD DIETS:“Anyone who wants to believe in them is forced to wonder how the thousands of scientists working on obesity research over the past century could possibly have missed such obvious connections.” Understanding Nutrition, 8th ed. Pg 251

12. What is a Fad Diet? • A fad diet is a weight loss plan or aid that promises dramatic results. These diets don't offer long-term success, and they are usually not very healthy. American Academy of Family Physicians

13. American Heart Association • “We want to inform the public about misleading weight-loss claims. Many of these diets — like the infamous Cabbage Soup Diet — can undermine your health, cause physical discomfort and lead to disappointment when you regain weight soon after you lose it…

14. American Heart Association • “Quick-weight-loss diets usually overemphasize one particular food or type of food. They violate the first principle of good nutrition: Eat a balanced diet that includes a variety of foods. If you are able to stay on such a diet for more than a few weeks, you may develop nutritional deficiencies, because no one type of food has all the nutrients you need for good health. The Cabbage Soup Diet mentioned above is an example. This so-called fat-burning soup is eaten mostly with fruits and vegetables. The diet supposedly helps heart patients lose 10–17 pounds in seven days before surgery. There are no "superfoods." That's why you should eat moderate amounts from all food groups, not large amounts of a few special foods…

15. American Heart Association • “These diets also violate a second important principle of good nutrition: Eating should be enjoyable. These diets are so monotonous and boring that it's almost impossible to stay on them for long periods.” http://www.americanheart.org/presenter.jhtml?identifier=4584

16. How to identify Fad Diets • Promise dramatic, rapid weight loss • Promote diets that are nutritionally unbalanced or extremely low in calories • Use liquid formulas rather than foods. • Attempt to make clients dependent upon special foods or devices. • Fail to encourage permanent, realistic lifestyle changes. Understanding Nutrition, 8th ed. Pg 253

17. How to identify Fad Diets • Misrepresent salespeople as “counselors” supposedly qualified to give guidance in nutrition and or general health. • Collect large sums of money at the start or require that clients sign contracts for expensive, long-term programs. • Fail to inform clients of the risks associated with weight loss in general or the specific program being promoted. Understanding Nutrition, 8th ed. Pg 253

18. How to identify Fad Diets • Promote unproven or spurious weight-loss aids such as starch blockers, diuretics, sauna belts, body wraps, passive exercise, ear stapling, acupuncture, electric muscle-stimulating devices, amino acid supplements, “unique” ingredients, etc • Fail to provide for weight maintenance after the program ends. Understanding Nutrition, 8th ed. Pg 253

19. If fad diets don't work, why are they so popular? • “People are often willing to try anything that promises to help them lose weight because they want to look or feel better, or because they are worried about getting weight-related diseases. Companies that promote fad diets take advantage of this fact. They appeal to people by promising weight loss that's very quick and easy. Many people prefer to try the quick fix of a fad diet instead of making the effort to lose weight through long-term changes in their eating and exercise habits.” American Academy of Family Physicians (AAFP) Website: http://familydoctor.org/784.xml

20. If fad diets don't work, why are they so popular? • “Fad diets also become popular because many of them do work for a short time. In many cases, this is because when you stop eating certain types of food or eat “special” combinations of foods, you are getting fewer calories than you normally would. You are also paying more attention to what you are eating. However, it’s likely that much of the weight you lose is from water and lean muscle, not body fat. Also, most people are not able to keep up with the demands of a diet that strictly limits their food choices or requires them to eat the same foods over and over again. People who use fad diets usually end up gaining back any weight that they lost.” American Academy of Family Physicians (AAFP) Website: http://familydoctor.org/784.xml

32. What’s the difference?

33. What’s the appeal? • Turns current diet recommendations upside down • Eat as much fat, meat, and dairy as you like • Ignore fruits, vegetables, and grains • “Steaks without the potatoes, ribs without the coleslaw, and meatballs without the pasta.” Understanding Nutrition, 8th ed. Pg 251

34. What’s the appeal? • Blame current diet recommendations for our obesity epidemic • Facts: • Obesity has risen • Fat intake has dropped from 36 to 34 percent • BUT… energy intake increased by 200 kcals a day  actual fat intake has increased by 4 grams a day! Understanding Nutrition, 8th ed. Pg 251

35. Why does it work? • Weight loss results because of a reduction in calorie intake • Protein is the most satiating…people feel more full… they eat less (it’s the calories) • Provides a guide… eliminating decision making

36. What are the risks? • Nausea • Fatigue • Constipation • Low blood pressure • Elevated uric acid • Stale foul taste in the mouth Understanding Nutrition, 8th ed. Pg 252

37. What are the risks? • Shift from lean body mass to fat • High protein usually means high fat! Diets high in fat, saturated fat, and cholesterol are risk factors for heart disease and atherosclerosis • Without fruits, vegetables, and grains the diet lacks fiber, vitamins and minerals. Understanding Nutrition, 8th ed. Pg 252
