Ignore the daily percentage values on food lables unless you want a 60% carb, 30% fat, and 10% protein diet.

Here's how I figured that out:

They recommend 65g of fat and 300g of carbs.
This is on a 2000 kcal diet, so if you multiply 300 by 4 and 65 by 9, you get 585 kcal of fat (or about 30%) and 1200 kcal (60%) of carbs. This only leaves 215 calories (or about 10%) for protein!

I'm sure many of you don't pay attention to those parts of the labels, but incase you do, you're not getting enough protein if you only get 10%.

How many of us really eat 2000 calories a day? Most of us are eating either more than that or less than that. The numbers on the labels are more helpful in comparing one food with another, than in checking how well it fits into your diet.

There's nothing wrong with a diet that gets 10% of calories from protein. Common dietary guidelines say that .75 g per 1 kg of body weight is enough, unless you are an athlete. For me, 55 x .75 = 41.25 g of protein per day, or 165 calories worth.

you're not getting enough protein if you only get 10%.
That's your opinion. If you want more protein than that, then, yes, you'll have to read the labels a little more carefully.

Should that be 300 g of carbs?

Where does fiber figure in here? There's some sort of subtraction you need to do somewhere. :confused:

Uh, yeah, thanks for seeing that. I guess that's my opinion, but I can't see how that little protein would be good for you, because it forces your diet to be high carb or high fat (the FDA's diet is high carb, I guess).

obviously, the daily percentage values is modeled for the "average" overweight American to continue being overweight.
