Where I live, you can buy 1% and you can buy skim. 1% is partially
skimmed.

3. Whole milk mixed with equal amounts tap water (1.5% fat) = 75
calories, $1.75/gallon, great taste.

What am I missing here???

If you dilute a glass of full fat milk so that it has only as much fat
as skim milk, you will end up with something that has next to no
protein and carbohydrates. It also has less calcium, less vitamins,
etc.

Adding water to milk does not change its /ratio/ of
protein:carbohydrate:fat calories. The resulting drink has fewer
overall calories, but in the same ratios. On the other hand, skim
milk actually has a greater percentage of calories from carbohydrates
and protein relative to fat.

This is why you should look carefully at products which are marketed
as ``low fat''. Many are targetted at naive shoppers who are taken in
by the low absolute fat content percentages quoted on the package,
which say little. The percentage of fat calories could be very high or
very low.

To calculate the percentage of calories from fat, multiply the fat
grams by 900, and divide by the total calories. If this comes out to
more than 40, leave the food on the store shelf.

Is 3% fat yogurt leaner than a 4% fat cheese? Yogurt is mostly water
compared to the solid, protein-dense cheese. Ignore the water; what
are the actual solids in there that you are paying for? Does it
really make sense to be dieting by eating fatty food, and padding up
the volume with water? If you think you need more water, then just
drink more of it!

Your analysis is exactly right. Skim milk is not 1% milk either. 1%
milk is 1% milk, but skim milk has all the fat removed so it is
essentially 0% fat. Yes, to understand percentages (of fat) in food,
you need to determine the percent of fat calories compared to the
total calories. This shows that 1% fat milk is still loaded with fat
with 2.5 grams of fat which totals 22.5 calories from fat in each cup
making the fat in 1% milk really 20% of the calories. dkw
