Energy Balance- in order to treat Body weight: understand that your change in weight: function of 2 variables:- How much you eat, how much you expend - change in weight = change in energy intake change in energy expenditure- glucose and amino acids go into the cytoplasm transformed into a glucose metabolite and pyruvate: yields energy in the form of ATP- fats: only go into the mitochondria as Acetyl CoA to be converted into ATP fats can't be converted into energy in the cytoplasm- end product of metabolism: ATP production (why we eat- to provide energy to body)- body uses ATPs but we eat food how these currencies of energy are converted back and forth?? II. Estimated Energy Content of Food A. Calorie (kilocalorie or 1000 calories) not direct measure of energy but measure of amount of heat required to raise 1 cc of water to 1 degree centigrade measure of transfer of energy...
