ow levels of body fat are a value to the performance of a number of sports. Thus, athletes often pursue fat loss. Sometimes this is chronically, and others attempt to reduce body mass and body fat acutely so they may compete in a certain weight class in weight-categorized sports.
Body fat is the most important component of mass loss, and lean body mass loss should be minimized when possible. To loss fat mass, both an exercise and eating program should be combined to provide a sustained and moderate energy deficit, but still allows the athlete to meet their nutritional needs.it is important to avoid rapid weight loss as due to possible health concerns and drastic decreases in performance.
Caloric restriction diets are often employed to …show more content…

Often individuals fail to maintain sufficient energy expenditure and/or a healthy calorically controlled dietary intake (Tate et al. (2007. Additionally deviations of an individual’s bodyweight also may trigger compensatory mechanisms in lipoprotein lipase activity, Ghrelin level alterations, and decrease in thermogenesis (Major et al., 2007; Dulloo, 2007).
Lipoprotein lipase
Lipoprotein Lipase is the enzyme responsible for fat synthesis and storage in adipose tissue which appears to become more active when a weight loss of approximately 15% of total body weight occurs due to signaling of increased appetite, particularly of that of fat, as well as an increased ability for other excess macronutrients to be converted to fatty acids (Gershoff, 1991, 1992; Nash, 1987; Schelkun, …show more content…

It should be noted that obese individuals appear leptin resistant and loss exhibit high levels of leptin whose function is blocked while simultaneously being overly sensitive to ghrelin (Ruda et al., 2006; Klok et al., 2007).
Research shows evidence that fat restrictions avoid increases in ghrelin caused by caloric restrictions (Weigle et al., 2003). This avoidance in ghrelin increase my make maintained of weight loss easier (Hansen et al., 2002; Klok et al., 2007; Leidy et al., 2007; Romon et al., 2006). Protein ingestion also appears to suppress ghrelin for long periods. Carbohydrates, however, initially suppress ghrelin more than protein but causes a rebound effect leading to higher levels of ghrelin hours after ingestion(Foster-Schubert et al., 2008).Ghrelin levels are counter regulatory mechanism for short but not long term energy deficiencies and thus return to baseline after several months of lower body mass (Garcia et al.,
