The Low Serotonin Theory A considerable body of evidence demonstrates that levels of serotonin in the brain play a major role in influencing eating behavior best buy female viagra menopause urine changes. Initial studies showed that when animals and humans are fed diets deficient in tryptophan order female viagra line menstruation and ovulation pro, appetite is significantly increased purchase 50mg female viagra free shipping women's health issues by age, resulting in binge eating of carbohydrates. Feeding animals or humans a carbohydrate meal leads to increased tryptophan delivery to the brain, resulting in the elevated manufacture of serotonin. This scenario has led to the idea that low serotonin levels contribute to carbohydrate cravings and play a major role in the development of obesity. Furthermore, it has been demonstrated that concentrations of tryptophan in the bloodstream and subsequent brain serotonin levels plummet with dieting. Cravings for carbohydrates due to low serotonin levels can be mild or quite severe. They may range in severity from the desire to nibble on a piece of bread or a cookie to uncontrollable binging. At the upper end of the spectrum of carbohydrate addiction is bulimia, a potentially serious eating disorder characterized by binge eating and purging of the food through forced vomiting or the use of laxatives. Therapeutic Considerations Long-term control of obesity is one of the greatest clinical challenges. Few people want to be overweight, and most overweight people express a strong desire to lose weight, yet only 5% of obese individuals can attain and maintain normal body weight for a year or more, while 66% of those just a few pounds or so overweight are able to do the same. The successful program for obesity is consistent with the basic foundations of good health—a positive mental attitude, a healthful lifestyle (especially important is regular exercise), a health- promoting diet, and supplementary measures. All of these components are interrelated, creating a situation in which no single component is more important than the others. Improvement in one facet may be enough to result in some positive changes, but incorporating all components yields the greatest results. Literally hundreds of diets and diet programs claim to be the answer to the problem of obesity. In order for an individual to lose weight, energy intake must be less than energy expenditure. This goal can be achieved by decreasing caloric intake or by increasing the rate at which calories are metabolized; the best results are achieved by doing both. To lose 1 pound, a person must consume 3,500 fewer calories than he or she expends. The loss of 1 lb each week requires a negative caloric balance of 500 calories a day. This can be achieved by decreasing the amount of calories ingested or by increasing exercise. Reducing a person’s caloric intake by 500 calories is often difficult, as is increasing metabolism by an additional 500 calories a day through exercise (accomplished by a 45-minute jog, playing tennis for an hour, or a brisk walk for 1. The most sensible approach to weight loss is to both decrease caloric intake and increase energy expenditure through exercise. Most individuals begin to lose weight if they decrease their caloric intake below 1,500 calories a day and exercise for 15 to 20 minutes three to four times per week. Starvation and crash diets usually result in rapid weight loss (largely of muscle and water) but cause rebound weight gain. The most successful approach to long-term, sustainable weight loss is gradual weight reduction (0. Exercise is critical to maintaining muscle mass and bone mineral density and to preventing the accumulation of abdominal fat, both during active weight loss and after weight loss has been achieved. For example, a 5 to 10% reduction in weight is accompanied by clinically meaningful improvements in cholesterol, blood pressure, and blood glucose levels. Behavioral Therapy Although clinical studies indicate that behavioral approaches to the management of obesity are often successful in achieving clinically significant weight loss, the lost weight is generally regained. The great majority of patients return to their pretreatment weight within three years. In order to provide the best insights on effective interventions, it is important to examine the psychological characteristics of people who have lost significant amounts of weight and experienced only minimal weight regain. For example, most obese patients who see a doctor about weight loss want to lose 20 to 30% of their body weight. Because most people lose only modest amounts of weight, many quickly lose the motivation and determination to keep the weight off. However, if people feel a significant boost to self-esteem and self-confidence, as well as have the experience of improving their appearance, feeling more attractive, and being able to wear more fashionable clothing, it can provide tremendous impetus for continued weight loss until goals are achieved. Remember that the majority of people want to lose weight for the changes in their physical appearance, not the health benefits. Although there is widespread awareness that being overweight is associated with increased health risks, relatively few patients give this as their reason for seeking treatment. Identifying patients’ primary goals for losing weight is a key step in helping them achieve success. Diet The dietary strategy that we recommend for obesity is the one given in the chapter “A Health- Promoting Diet. We recommend 2 g protein daily per kg of body weight unless a person is showing signs of kidney failure. The importance of higher protein consumption was demonstrated in the Diogenes Study (Diogenes is an acronym for “Diet, Obesity, and Genes”). The five-year program involved 29 world- class centers in diet and health studies, epidemiology, dietary genomics, and food technology across Europe. More than 700 overweight adults from eight European countries who had lost at least 8% of their initial body weight with an 800-calorie diet (mean initial weight loss was 24. The participants were to stay on the diet for 26 weeks, and the amount they could eat was not controlled. Fewer participants dropped out in the high-protein/high glycemic and high-protein/low-glycemic groups than in the low-protein/high-glycemic group (26. Among participants who completed the study, only the low- protein/high-glycemic diet was associated with subsequent significant weight regain (3.
