We are designing a diet plan for ed.
00:03
It needs to have 2 ,100 calories.
00:06
50 % are from carbs, 20 % are from protein, 30 % from fat.
00:14
So how many grams of each does he need per day? okay, so first of all, we're going to work at how many calories he's getting from each.
00:23
Because we know how many calories total.
00:25
We know the percentages.
00:26
So let's translate that into actual hard numbers.
00:31
So for example, for carbs, 50 % of this 2 ,100 has to be from carbs.
00:37
So we just multiply this by 50%.
00:40
So that's 0 .5, which gives us 1 ,050 calories from carbohydrates.
00:48
Okay, protein has to be 20%.
00:51
So we multiply it by 0 .2.
00:55
So 0 .2 times 2 ,000.
00:59
Is 420 calories.
01:02
And finally, the fats, so 30 % are from fats, 0 .3 times 2 ,100 is 6 ,30.
01:14
And if you wanted to check, if we add these up, they all add up to the total 2 ,100, so that's a good sign...
