Okay, I wanted to go over the AMDR. Basically it is just a way that people can talk about the distribution of where your energy should be coming from in relationship to the macro nutrients. So those macro nutrients being carbohydrates, lipids, and then proteins. Currently what people are saying is approximately 45 to 65% of your total calories should be coming from carbohydrates, 20 to 35% of those calories should be coming from lipids, and then 10 to 35% of your total calories should be coming from protein. So other important numbers that kind of be aware of is actually how many calories there are per unit of measurement of mass. So four kilocalories of carbohydrates is equivalent to one gram of carbohydrates, and then also nine kilocalories of lipids is equivalent to one gram, and four kilocalories of protein will come from one gram. So basically if you have one gram of carbohydrates you should have approximately four kilocalories in that food. So what we need to do is figure out how we can use that. So we may have a diet where we have a particular number of kilocalories you want to aim for, and we may want to have a certain number of carbohydrates, or at least a percentage of calories coming from those carbohydrates, and now we can utilize these numbers to figure out how much carbs we really need in terms of the amount. So let's go over the first problem here. So here we got a scenario. We got Susie's told to consume a diet with the total number of kilocalories set at 1,850. So that's our total number that we need to be worried about. So what we want to know is how many grams of protein she would have in her diet, or should she have in her diet. So now we need to do a little bit of math. And since we're dealing with protein we'll need to come back up here and look and see that well we need 10 to 35% of the calories should actually come from protein. So we'll need to utilize that to figure out how many grams that she should have in that diet to have a proper diet. So here's some numbers just so we can start doing some calculation. So here's the total number calories we had talked about 1,850. To figure out 10% of those calories or what 10% of 8,150 is we can multiply that by 0.10. And if we do that we'll get 185 kilocalories. So what that's saying is 185 kilocalories is 10% of that total number. To do 35% we'll take 1,850 and we'll multiply that by 0.35. When we do that we'll get 647.5 kilocalories. And so now what we've just done is here is our distribution range in terms of proteins in terms of how many calories should be coming from proteins. So we should have between 185 kilocalories to 647.5 kilocalories coming from protein. Now the problem that we have now is we've got to get this converted into actual grams, a measurement that we can use. So to do that we're going to do some math here and we're going to utilize that 4 kilocalories per gram measurement that we talked about earlier. So here we got my 185 kilocalories. And what I'm going to do is just put this as a proportion here. So 1 gram is equivalent to 4 kilocalories. And when I do this and I do a multiplication what we'll see is my kilocalories will cross out and I'll be left with my grams number. And so 10% then of my calories would actually be about 46.25 grams of protein. Now to figure out the 647 one we divide that by four and we'll get 161.9 grams. So basically what we're saying is Sally needs a per our Susie needs approximately 46.25 grams to 161.9 grams to fit within the AMDR range of proteins. So that's how you'll do a problem number one.
