Nutrition - Essay Example in the for of triglycerides, proteins in the form of amino acids, nucleotides in the form of nucleic acids after being absorbed and transported into individual cells may undergo metabolism, thus releasing ATP or free energy to sustain the activities of the organ system and the whole body collectively. The extra glucose will be converted by the liver as stored glycogen and the extra lipids will be stored as fats. In case of additional intake of food when cells needs are just satiated or satisfied, the liver takes care of the storage of the extra materials. In increased respiratory function brought about by exercise, stored glucose and fats will be tapped to produce replacement ATP’s. Increased respiratory functions through exercise then must be good because in excessive storage of fats, according to the study conducted by Ziccardi P. et al (2002), concentrations of pro-inflammatory cytokines are higher which are found to be tumor necrosis factor ÃŽ ± (TNF- ÃŽ ±) and interleukin-6 (IL-6). On the other hand, weight loss resulted to reduced fats, reduced concentrations of ÃŽ ± (TNF- ÃŽ ±), reduced interleukin-6 (IL-6), reduced P-selectin, reduced ICAM-1, and reduced VCAM-1 (Ziccardi P. et al 2002). Thus, weight loss through exercise would bring down the level of endothelial dysfunction such as inflammations as a consequence of the lowered level of the most likely trigger factors, cytokines, consequently, reducing also the risk of artherothrombosis (Ziccardi P. et al 2002). Furthermore, exercise and weight loss are the closest mean s by which inflammatory process impact may be lessened (Visser 1999). 2. Blundell and Hill (1992), showed a diagram explaining the biological regulation which starts with the brain including environmental adaptation driving eating behavior for the body to gain the nutrition needed for physiologic function. Hunger and thirst normally drives food intake, which are basically stimulated by Ghrelin molecules that relays the message to the
