For obese individuals on the Atkins diet, a moderate exercise program that allows the body to burn fat rather than glycogen can be beneficial, since they would be able to exercise longer. For trained athletes, a higher level of exercise at a longer duration is possible, since the body's threshold for the change to using glycogen as ATP is higher.
Thus, our results that obese individuals on that Atkins diet who participate in moderate activity are able to exercise for longer periods of time is supported.
In conclusion, our results indicated that weight loss in our subjects was caused from a negative energy balance, rather than metabolic advantage. The Atkins diet works well not because of a lowered carbohydrate intake, but because of a lowered overall food and caloric intake. This lower level of food intake in turn leads to a higher ratio between energy output, and energy intake. These results are further improved with the addition of moderate exercise, since the diet would improve overall exercise performance, and allow the body to burn more fat. Additionally, and for the same reasons, the Atkins diet would also serve highly trained athletes participating in endurance training.

Eating for Good Health - Safe Weight Loss vs. Fad Dieting This paper explores the need for safe weight loss and healthy eating, as opposed to the fad diets often featured on television, in newspapers and in magazines. For the purposes of this paper, healthy eating is defined according to the standards set out by the U.S. government in its 2000 guidelines on nutrition. The diet industry globally makes millions of dollars
More specifically, when certain species (including homo Sapiens) consume more calories than necessary for immediate energy requirements, their digestive systems efficiently converts those excess calories into storable forms of reserve energy that are capable of being called upon in times of need (Larson-Duyff, 2005; Rinzler, 2004). In humans, excess caloric consumption increases the amount of sugars dissolved in the blood (Larson-Duyff, 2005; Rinzler, 2004). This triggers a natural insulin response
Obesity in America Many think of obesity as a disease that may need medication to retract, may be genetic in origin and, thus, not the fault of the individual, and, therefore, may be biologically rather than culturally deteremined. However, as this essay intends to show, people with genetic predisposition to obesity can still prevent their obesity from occuring, or can control it, by followign the guidelines of a healthy diet and
" (1999) Moran states that it has been demonstrated in many studies that a "familial aggregation f risk factors for obesity exist and the family "provides the child's major social learning environment." (1999) Surgical and Pharmacological Treatment There is very little conclusive research in the area of surgical and pharmacological treatment of child and adolescent obesity. These types of treatments are generally considered by HCPs to be "last resorts" (NIHCM, 2004) the
