How much do I way the next morning, what percentage of my weight is pure body fat, and what percentage is pure muscle if I have a slow metabolism?

How much do I way the next morning …

Your mass (or weight, as it’s more commonly referred to informally) can and typically does vary significantly from day to day and during the day, mostly due to gaining and losing water. Making precise predictions from a catalog of food and exercise is practically impossible. Averaged over many days, however, it’s fairly easy to document the connection between exercise, food eaten, and body mass.

 

Although eating a variety of good foods is important to assure you get all the amino acids and vitamins needed for good health, contrary to the claims of countless “fad diets”, nearly all foods provide about the same amount of metabolic energy for a give dry mass, and nearly exactly the same amount of metabolic energy as thermal energy produced by burning them (note I say “about” - alcohol and fat have about 2 times the energy density of sugar and protein). Fortunately, in the US, nearly all foods are labeled with their energy content in large calories, so we don’t have to conduct experiments to figure them out.

 

Bottom line:the most important thing to count in a food diary are calories.

… what percentage of my weight is pure body fat, and what percentage is pure muscle if I have a slow metabolism?
This wikipedia article describes a procedure for determining your body’s average density using a swimming pool and ordinary plastic bottles. It’s only approximate, however – bone density and other complicated factors make an exact measurement of body fat practically impossible without using advanced (and expensive) medical imaging technology.

there's also hand-held Body fat percentage testers that work via imputting your weight etc... into it and then grabbing two electrodes while they pass electricity hrough you, th resistance values give a fairly accurate BFP result. I used to use one every couple of weeks in my active living(re: Weight lifting) class in highschool.

 

Google it or go to a fitness club to see if they have one.
